The main purpose
1. Mainly used as a monomer for the manufacture of EVA resin and VAE emulsion by copolymerization with vinyl acetate, used for the manufacture of adhesives and coatings, etc. Ethylene is one of the basic raw materials of petrochemical industry and is widely used. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, styrene and polystyrene, and ethylene-propylene rubber. In terms of organic synthesis, it is widely used in the synthesis of ethanol, ethylene oxide, ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and its derivatives as basic organic synthesis raw materials; through halogenation, it can produce chloroethylene, chlorine Ethane and ethyl bromide; through oligomerization, α-olefins can be produced, and then higher alcohols, alkylbenzenes, etc. can be produced, which are used for the development of synthetic resins, synthetic fibers, synthetic rubber, basic organic synthetic raw materials, and fine chemicals, such as Pesticides, medicines, dyes, coatings, additives, surfactants, spices and ion exchange resins, etc.,Can provide a wealth of basic chemical raw materials. It is used as a fruit ripening agent in agriculture, but ethylene can also accelerate the decomposition of chlorophyll, turn fruits and vegetables yellow, and promote the aging and quality decline of fruits and vegetables. Therefore, the use of ethylene as a fruit ripening agent must be done before the fruit matures, and the treatment concentration and time must be appropriate. In order to slow down the ripening and senescence of fruits and vegetables after harvest, it is also necessary to control the amount of ethylene produced by fruits in the storage environment. 2. Used in the manufacture of synthetic rubber, synthetic resin, synthetic fiber, plastic, etc. It can also synthesize explosives and organic synthesis products such as ethanol, acetaldehyde, acetic acid, and ethylene oxide, and can replace acetylene for cutting and welding metals, and can also be used as an accelerator for fruit ripening. 3. Used to make polyethylene, polyvinyl chloride, acetic acid, etc.
