In 1993, the International Union of Pure and Applied Chemistry (IUPAC) issued its final nomenclature for organic compounds. Nomenclature (Nomenclature), as the name suggests, is the method of naming compounds. If we want to give each organic compound a name, we obviously cannot write all possible organic compounds and their names into a table. So we need to write a few very concise rules to help us quickly name even a compound that has never been seen before.

Naming structure The naming structure of organic compounds can be basically split into prefix (Prefix) and suffix (Suffix). The prefix generally indicates how many carbon atoms are in the compound. The suffix represents which functional groups (Functional Group) are contained in the compound. In other words, the suffix represents which organic compound this organic compound belongs to, such as alkanes (Alkane), alkenes (Alkene), alcohols (Alcohol) and so on. There is nothing to say about the prefix. It is purely a one-to-one table: 1 Carbon: Meth- 2 Carbons: Eth- 3 Carbons: Prop- 4 Carbons: But- 5 Carbons: Pent- 6 Carbons: Hex- 7 Carbons: Hept- 8 Carbons: Oct- 9 Carbons: Non- 10 Carbons: Dec- 11 Carbons: Undec- 12 Carbons: Dodec- … In IGCSE chemistry, we rarely see names above 7 Carbons. So everything from Meth- to Hex- must be memorized. No way, just memorize it by rote. The prefixes are only associated with carbon atoms, so you don’t need to count hydrogen atoms. You see several carbon atoms, and its prefix is the corresponding prefix. Let’s take an example.

Now that the prefixes are finished, let’s talk about suffixes. If there are only Carbon-Carbon single bond and Carbon-Hydrogen single bond in a compound, then it belongs to alkane (Alkane). Let’s take a look at the name Alkane. It can be split into Alk- prefix and -ane suffix. The Alk- prefix represents a comprehensive compound category. It does not specify the length, but it is just a placeholder. So of course, -ane is the common suffix of this kind of compound.

We still see our three previous examples. Take a closer look, in each compound, each atom is connected with a single bond (a horizontal line), so we can say that all three of them belong to Alkane, and their suffixes are all -ane. So we have a prefix, and we have a suffix, and we can name it. The first compound has the prefix Meth- and the suffix -ane, so the full name is Methane. The second compound has the prefix But- and the suffix -ane, so the full name is Butane. The third compound has a prefix of Pent- and a suffix of -ane, so its full name is Pentane. simple right?

Types of Pentane and Pentane Blowing Agents

Pentanes include n-pentane, isopentane and cyclopentane. The molecular formula is C5H12 and the molecular weight is 72.15. Cyclopentane, also known as “pentamethylene”, is a cycloalkane with the molecular formula C5H10. Molecular weight 70.13. flammable liquid.

It’s essential to know about hydrocarbons, increasingly present in the market.

The use of R600a and R290 hydrocarbons as refrigerant fluids has been consolidating itself and gaining space in the market. By representing, at the same time, a good solution from a technical point of view as well as a response to the need to cause less environment impact, they have been adopted by various refrigeration equipment manufacturers.

From an environmental aspect, it should be emphasized that they do not harm the ozone layer and contribute almost negligibly to global warming – a considerable advantage over many other alternatives now present in the market. Another advantage is that their use delivers greater cooling system efficiency. For those not familiar with these refrigerants yet, it’s worth noting that R600a or isobutane, is mainly used in household refrigerators and some types of commercial equipment, while R290, or propane, is an alternative increasingly more present in commercial equipment. There is still a degree of concern from some professionals and companies in relation to the use of hydrocarbons, since they are flammable. But it’s an unnecessary concern. Knowing how to work with them, there’s no risk. The example of several European countries proves this: there, isobutane and propane have been used for many years.

There is other information that should be emphasized to make it clear how safe their use is. The first is that the entire electrical circuit of these products is suitable for flammable gases to prevent generating sparks. Added to this, it’s important to know that the hydrocarbon charge in a refrigerator is very small, being around 80 grams for household systems and 150 grams for commercial systems. Let’s compare: the hydrocarbon mass of a refrigerator is about 1% of the total existing in a 13 kg gas cylinder, which is commonly used in kitchens. Since the refrigeration systems are sealed, the gas doesn’t come in contact with the environment.

COOKING GAS MUST NOT BE USED

Liquefied petroleum gas (LPG), also known as cooking gas, cannot be used as a refrigerant fluid in refrigeration equipment. For this use, only isobutane (R600a) and propane (R290) hydrocarbons are indicated. LPG is a mixture of butane and propane, with different characteristics both for R600a as well as for R290 and its use can generate moisture in the system, among other problems. In addition to the different chemical composition, it receives an additive to have an odor that makes it easy to notice leaks and this additive can also react with the elements present in the refrigeration system. 

Necessary precautions

It’s important to be aware of the characteristics of these refrigerant fluids when doing maintenance on equipment in which they are used. Since they’re flammable, some precautions should be taken:

• Before beginning, it’s important to consult technical reference materials, reinforcing your knowledge on best practices and precautions to be taken.

• In welding operations, release all the refrigerant from the refrigeration system in a well-ventilated area or collect it in a closed container. Make sure that the tubing is completely free of isobutane or propane before using the welding torch. For this, a nitrogen charge can be passed through the tubing.

• Seal the process tube with locking pliers.

• You can also choose to use the Lokring® system to join the tubes, avoiding the need to weld

• Be attentive to the electrical devices which need to be appropriate to the flammability of these refrigerants.

A key guideline is that isobutane and propane should only be used in compressors that are designed for their use. That’s what will ensure good system performance and operational safety. Regarding electrical components, the need to use starting devices approved for the compressor must be emphasized. The thermal protector must be ¾ sealed (with cover) or the 4TM model.

Other important information is about filter driers, which should contain 4A-XH5 desiccant. Some refrigeration system characteristics change when using hydrocarbons. And, in some aspects, there are important differences among the systems with R600a and those designed for use with R290. For example, an R600a compressor has a displacement approximately 70% greater than a similar model with R134a. R600a also has lower vapor pressures than R12 or R134a, in all temperature ranges.

While in the case of propane, the situation is different. In R290 compressors the displaced volume is always smaller, reaching up to a 40% reduction when compared to R134a models. Propane operates with higher pressures compared to R600a or R134a. Regarding gas charge, the characteristic is the same for both R600a and for R290: in both cases it’s normally 40% lower when compared to other refrigerants – another reason why there should be no fears about the operational safety of hydrocarbons. In other aspects, there are few changes.

In the case of capillary tubes and heat exchangers (evaporators and condensers), almost always the same system characteristics that operate with other refrigerants are maintained. Finally, a key recommendation: in systems designed for the use of hydrocarbons, never replace them with other refrigerant fluids.

Tip: If you have doubts or want to enhance your knowledge on this topic, watch the video on changing compressors available on the Club’s website (refrigerationclub.com). The compressor shown there uses hydrocarbon.

Which refrigerators use R600a refrigerant?

This is a great, energy-efficient French-door refrigerator, the most popular style right now. It stores a lot of food and uses the climate-friendly R600a refrigerant.

What is Isohexane?

Isohexane, also known as 2-methylpentane, is a colorless liquid. The chemical is a six-carbon chain with a branching methyl hydrocarbon group coming off of it. It is a highly non-polar chemical, as it only consists of hydrogens and carbons, neither of which have a high electrical pull, meaning they are both uncharged.

Is Isohexane Safe?

This is a highly flammable chemical. While it is unreactive on its own, it should be kept away from heat and flame, as it will almost immediately catch on fire.

Due to isohexane’s non-polar nature, it is a good solvent for removing fats and oils from substances. Because of this, it can cause dryness and cracking in skin when there is prolonged or repeated contact with the skin. This generally happens when it comes into contact with the hands, and thus gloves should be used whenever handling this chemical.

Isohexane is also an irritant, as most chemicals are. It is irritating to the eyes and skin when they come into contact with the chemical. More seriously, this chemical can cause central nervous system depression. When one comes into contact with isohexane in high concentrations or for a long period of time, loss of consciousness may occur.

Proper precautions, such as wearing safety goggles, using the chemical in an area with good ventilation and removing flame from the work area, along with storing the chemical properly can reduce the possibility of harm coming to those utilizing the chemical.

What is Isohexane Used in?

Isohexane is used in a wide variety of different substances found in everyday life. This includes, but is not limited to:

• Gasoline
• Glues
• Shoes
• Leather products
• Roofing products
• Extraction of oils
• Cleansing agents for leather
• Furniture manufacturing
• Textile manufacturing
