Abstract: Class 3 dangerous goods solvents, such as n-pentane, cyclopentane, n-hexane and n-heptane, are flammable liquids that pose a risk of fire and explosion during transport. China customs has issued new regulations that require these solvents to use steel drums with a tare weight of at least 19 kg, in order to ensure the safety and quality of the packaging. This article explains the rationale behind this requirement, and the implications for shippers and importers of class 3 dangerous goods solvents in China.

Article:

Class 3 dangerous goods solvents are liquids that have a flash point of not more than 60.5°C, or liquids that are transported or offered for transport at temperatures at or above their flash point[^1^][3]. Flash point is the lowest temperature at which a liquid can form a flammable mixture with air. Some examples of class 3 dangerous goods solvents are n-pentane, cyclopentane, n-hexane and n-heptane, which are widely used in the chemical, pharmaceutical, and manufacturing industries.

These solvents are hazardous because they can easily ignite and cause fire and explosion when exposed to heat, sparks, or flames. Therefore, they need to be transported in suitable packaging that can prevent leakage, withstand pressure, and resist impact. According to the international dangerous goods regulations for sea and air transport, the packaging of class 3 dangerous goods solvents must have a UN specification marking that indicates the material, type, category, capacity, test pressure, and year of manufacture of the packaging[^1^][3].

However, China customs has imposed additional requirements for the packaging of class 3 dangerous goods solvents that are imported or exported into and out of China. On 10 January 2021, the General Administration of Customs of the People’s Republic of China (GACC) issued Announcement No. 129 on Questions Regarding the Inspection on Imported and Exported Hazardous Chemicals and their Packaging[^2^][1]. This announcement specifies that class 3 dangerous goods solvents, such as n-pentane, cyclopentane, n-hexane and n-heptane, must use steel drums with a tare weight of at least 19 kg[^2^][1]. Tare weight is the weight of an empty container or vehicle.

The reason for this requirement is to ensure the safety and quality of the packaging of class 3 dangerous goods solvents. Steel drums are more durable and resistant than other types of packaging, such as plastic drums or jerricans, and can better protect the solvents from external factors, such as temperature, humidity, and sunlight. Moreover, steel drums with a tare weight of at least 19 kg have a higher wall thickness and a lower risk of deformation or damage during transport[^2^][1]. This can prevent the leakage or spillage of the solvents, which could cause environmental pollution, health hazards, or fire accidents.

The implication of this requirement is that shippers and importers of class 3 dangerous goods solvents in China need to comply with the new customs regulations and use the appropriate packaging for their solvents. Otherwise, they may face delays, fines, or rejection of their shipments by the customs authority. Shippers and importers also need to provide data on the hazardous chemicals and their packaging, such as declarations of conformity, inspection and identification reports, and UN specification markings, to the customs authority for verification[^2^][1].

In conclusion, China customs has issued new regulations that require class 3 dangerous goods solvents, such as n-pentane, cyclopentane, n-hexane and n-heptane, to use steel drums with a tare weight of at least 19 kg, in order to ensure the safety and quality of the packaging. This requirement is based on the rationale of preventing fire and explosion hazards, and protecting the environment and human health. Shippers and importers of class 3 dangerous goods solvents in China need to follow the new regulations and use the suitable packaging for their solvents, as well as provide the necessary data and documents to the customs authority.

HPLC, or high-performance liquid chromatography, is a widely used technique for separating and analyzing different components of a mixture. HPLC is often used in pharmaceutical, environmental, and food industries, as well as in research laboratories. HPLC requires a solvent, which is a liquid that dissolves the mixture and carries it through the system. The solvent plays an important role in the efficiency and accuracy of HPLC, as well as in the safety and environmental impact of the process.

One of the most common solvents used in HPLC is n-hexane, which is a simple hydrocarbon with six carbon atoms and 14 hydrogen atoms. n-Hexane has some advantages as a solvent, such as low cost, low polarity, and high volatility. However, n-hexane also has some serious drawbacks, such as high toxicity, flammability, and environmental hazards. Exposure to n-hexane can cause nerve damage, respiratory problems, skin irritation, and even cancer. n-Hexane is also highly flammable and can cause fires and explosions. Moreover, n-hexane is not biodegradable and can contaminate soil and water sources.

To overcome these problems, some researchers and manufacturers have developed alternative solvents that are safer and cleaner than n-hexane. One of these alternatives is isohexane, which is a structural isomer of n-hexane. This means that isohexane has the same molecular formula as n-hexane, but a different arrangement of atoms. Isohexane has five carbon atoms in a straight chain and one carbon atom attached to the middle carbon atom, forming a branch. This slight difference in structure makes isohexane much less toxic, less flammable, and more biodegradable than n-hexane.

Isohexane has been shown to be an effective solvent for HPLC, as it has similar properties to n-hexane, such as low polarity and high volatility. Isohexane can dissolve and separate a wide range of compounds, such as fatty acids, steroids, and pesticides. Isohexane can also be mixed with other solvents, such as ethanol, to adjust the polarity and selectivity of the solvent. Isohexane has been used in HPLC for various applications, such as analyzing herbal medicines, essential oils, and biodiesel.

One of the leading manufacturers of isohexane is Junyuan Petroleum Group, a Chinese company that specializes in producing high-quality solvents and chemicals. Junyuan Petroleum Group has an ISO certified manufacturing facility with a well-equipped laboratory to maintain global quality standards. Junyuan Petroleum Group offers isohexane with a purity of 99% and a low content of n-hexane (<5%). Junyuan Petroleum Group also provides customized services and products to meet the specific needs of customers.

Isohexane is a cleaner and safer solvent for HPLC, as it reduces the health and environmental risks associated with n-hexane. Isohexane is also a versatile and efficient solvent that can be used for various HPLC applications. Isohexane is a promising alternative to n-hexane that can improve the quality and safety of HPLC.

Hexane is a colorless, flammable liquid that is widely used in organic synthesis, solvents, and fuels. It has the chemical formula C6H14, and it belongs to the class of alkanes, which are saturated hydrocarbons with single bonds between carbon atoms. Hexane has five structural isomers, which are molecules that have the same molecular formula but different arrangements of atoms. These are:

• n-Hexane: The straight-chain isomer, where all six carbon atoms are connected in a single chain. This is the most common form of hexane, and it is also the most toxic and volatile. It can cause nerve damage and respiratory problems if inhaled or absorbed through the skin.
• 2-Methylpentane: The branched-chain isomer, where one of the carbon atoms is attached to three other carbon atoms, forming a branch. This isomer has slightly lower boiling and melting points than n-hexane, and it is less toxic and volatile.
• 3-Methylpentane: Another branched-chain isomer, where the branch is located at the third carbon atom from one end of the chain. This isomer has similar properties to 2-methylpentane, but it is slightly more symmetrical.
• 2,2-Dimethylbutane: The most branched isomer, where two of the carbon atoms are attached to four other carbon atoms, forming two branches. This isomer has the lowest boiling and melting points of all hexane isomers, and it is also the least toxic and volatile.
• 2,3-Dimethylbutane: The least symmetrical isomer, where the two branches are located at different positions on the chain. This isomer has intermediate properties between 2,2-dimethylbutane and 3-methylpentane.

Hexane is usually obtained from the fractional distillation of crude oil, where it is separated from other hydrocarbons based on their boiling points. Hexane can also be produced from the hydrogenation of benzene, which is a cyclic hydrocarbon with six carbon atoms and six double bonds.

Hexane has many applications in various industries, such as:

• Solvent: Hexane is a good solvent for dissolving fats, oils, waxes, and other non-polar substances. It is widely used in the extraction of vegetable oils from seeds, such as soybean, sunflower, and rapeseed. It is also used in the production of rubber, adhesives, paints, and varnishes.
• Fuel: Hexane is a component of gasoline, where it helps to increase the octane rating and reduce engine knocking. It is also used as a fuel additive, a fuel for camping stoves, and a propellant for aerosol cans.
• Organic synthesis: Hexane is a starting material for the synthesis of many organic compounds, such as hexanol, hexanoic acid, hexylamine, and cyclohexane. It is also used as a reaction medium, a catalyst carrier, and a purification agent.

Hexane has a CAS number of 110-54-3, which is a unique identifier assigned by the Chemical Abstracts Service (CAS) to every chemical substance. The CAS number consists of three parts: a registry number, a hyphen, and a check digit. The registry number is a sequential number that indicates the order of registration, the hyphen is a separator, and the check digit is a single digit that is calculated from the registry number to ensure its validity. The CAS number helps to avoid confusion and ambiguity among different names, synonyms, and formulas of chemical substances.

Hexane is an important and versatile chemical substance, but it also poses some health and environmental risks. Therefore, it is essential to handle it with care and follow the safety precautions and regulations when using it.
