R1150 refrigerant Ethylene is an important basic raw material for organic chemical industry, and is one of the most basic raw materials for petrochemical industry, mainly used in the production of polyethylene, ethylene propylene rubber, polyvinyl chloride, etc. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, styrene and polystyrene, as well as ethylene propylene rubber, etc. In terms of chemicalbook organic synthesis, it is widely used in the synthesis of ethanol, ethylene oxide and ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and its derivatives, etc. Basic organic synthesis raw materials; after halogenation, vinyl chloride, ethyl chloride, ethyl bromide can be produced; after polymerization, α-olefins can be produced, and then higher alcohols, alkylbenzenes, etc. can be produced.
In the process of forming ethylene molecules, each carbon atom forms a bond with 1 2s orbital and 2 2p orbitals to form 3 equivalent sp2 hybrid orbitals. These 3 sp2 hybrid orbitals are in the same plane, forming an angle of 120° with each other. Therefore, five σ bonds are formed in the ethylene molecule, of which four are C-H bonds (sp2-s) and one is C-C bond (sp2-sp2); the two parallel p orbitals of the two carbon atoms that have not participated in the hybridization overlap on the side to form another chemical bond: π bond, which is perpendicular to the plane where the σ bond is located. For example, the C=C double bond in the ethylene molecule is formed by a σ bond and a π bond. The orbital overlap of these two bonds is different. The π bond is formed by the overlap of the p orbitals from the side, and the overlap is smaller than that of the σ bond from the front, so the π bond is not as strong as the σ bond, and it is easier to break, and the energy required for breaking is also less.
The company has built multiple sets of high-purity gas filling systems and purification systems, equipped with advanced gas production, purification, and analysis equipment, which can fill and produce a variety of 5N high-purity gases and 6N ultra-pure gases. We have established strict specifications and processes. All production personnel have received professional training and obtained certification.
