On July 29, the emergency management department held a quarterly video promotion meeting on the centralized management of safety risks of hazardous chemicals nationwide to report progress, analyze problems, exchange practices, strengthen measures, promote the implementation of key tasks, effectively prevent and control major safety risks, and create a stable safety environment for the success of the 20th CPC National Congress. Sunguangyu, member of the Party committee and vice minister of the emergency management department, attended the meeting and delivered a speech. Qichunxiao, the general manager of the group, and Qiao Huijie, the deputy general manager and director of safety and environmental protection, attended the video conference at the venue of the agricultural high-tech division in the Yellow River Delta.

However, from the mid-term evaluation results of centralized governance, there are still problems of uneven progress between regions, lagging progress of some special projects and low quality.

The meeting emphasized that we should have a clear understanding of the severe situation faced by the current safe production of hazardous chemicals and strengthen the sense of mission and urgency of doing a good job in centralized management. We should adhere to the problem orientation, anchor the goal of centralized governance, and make every effort to overcome difficulties. We should quickly wake up, be nervous, and take action. If there is a deviation in the direction of work, we should correct it in time. If the progress of work lags behind, we should pay close attention to make-up lessons, and accelerate the completion.

The meeting required that we should adhere to both the symptoms and root causes, accurately grasp the relationship between major risk prevention and control and centralized governance, promote major risk prevention and control and centralized governance as a whole, and prevent “two skins”. We should organically integrate centralized management and annual key work, integrate the requirements of centralized management tasks and measures into the major inspection of production safety and special safety actions, strengthen supervision and inspection and open and secret visits, do a good job in production safety in summer and flood seasons, strictly implement the main responsibility of enterprises, and resolutely prevent and contain major accidents and accidents with great impact.

At the meeting, Beijing, Liaoning, Zhejiang, Ningxia and other four provinces and CNPC made exchange speeches respectively, and the heads of relevant departments and bureaus, institutions and industry associations of the emergency management department and the main heads of relevant central enterprise safety management departments attended the meeting at the main venue; The heads of the emergency management departments at the provincial, municipal and county levels, as well as the relevant chemical parks and the main heads of enterprises attended the meeting at the branch venue.

Physical Properties The boiling points of the pentane isomers range from about 9 to 36 °C. As is the case for other alkanes, the more branched isomers tend to have lower boiling points.

Usually, n-Pentane is used as a refrigeration or air conditioning substance, effectively replacing substances such as fluorinated hydrocarbons and ammonia. Here are some of its potential uses: refrigerant R601, non-polar solvent polyethylene process medium, how to use Isopentane? Isopentane is widely used. Firstly, it is an important refrigerant, which is used as the mixed refrigerant component of condensation inducer and LNG in LLDPE unit of olefin plant; Used for blending octane number of oil products;

Usage: isopentane is widely used. First, it is an important refrigerant of olefin unit, condensation inducer of LLDPE unit and LNG mixed refrigerant components; Used for blending oil octane number; It is widely used in organic synthesis reactions and the separation and purification of organic compounds; Secondly, isopentane dehydrogenation can be made of isoprene and isoprene, and isopentanol is obtained by chlorination and hydrolysis. It is also an important raw material for organic synthesis. Isopentane can also be used with n-pentane in EPS (expandable polystyrene) blowing agent, or with cyclopentane as rigid polyurethane blowing agent. It is mainly used in organic synthesis and also as a solvent.

Cyclopentane, as a blowing agent in Polyurethane (PU) foams, is the most important raw material for high-performance insulation in refrigerators. 

Pentane, C₅H_12, is a clear colorless liquid with a petroleum-like odor. It belongs to the organic class alkanes, and is naturally present in crude oils and condensates. It is a component of some fuels and is employed as a specialty solvent in the laboratory.

The boling point 36°C/97°F, and the vapors are heavier than air. Both the liquid an the vapor are flammable.
