Hydrocarbons

It is used in the production of surfactant, bactericide and detergent. Intermediate of surfactant, also used as bactericide; Production of detergent, etc.

As for butene, it is mainly used in three aspects. One is as a fuel filler. After alkylation, the product can improve the octane number and can be used as alkylated gasoline or gasoline additive. Second, as a monomer during polymerization, it can be oligomerized, homopolymerized and copolymerized. Polybutene is a long-chain monoolefin, which is not dry and cross-linked. It can be used as oil additive, adhesive, lubricant, compressor oil and cable impregnation oil; The copolymer can be used to produce rubber, plastic, resin and gum base of gum sugar. Third, it is widely used as chemical raw materials. N-butene can be used to prepare sec butanol, methyl ethyl ketone, butadiene, maleic anhydride, acetic acid, pentanol and so on. Isobutylene can be used to prepare neopentyl alcohol, neopentyl aldehyde and neopentyl acid; As tert butyl agent, tert butyl benzene, tert butyl amine, tert butyl mercaptan, p-tert butyl toluene, etc. are prepared; Methacrolein and methacrylic acid can be prepared by oxidation; Reaction with formaldehyde to prepare isoprene; Preparation of methacrylonitrile and methacrylic acid by ammoxidation; Reaction with methanol to prepare methyl tert butyl ether; Used as gasoline additive; Pesticide raw materials to produce "DV pyrethrin", "permethrin", "cypermethrin" and "permethrin"; After alkylation, antioxidants, anti-aging agents and heat stabilizers can be prepared; React with acetic acid to prepare butyl acetate, which can be used as perfume; React with formaldehyde to prepare isoprene, and further prepare a series of spices and rubber; Chlorination, which can prepare methyl allyl chloride β- Epichlorohydrin; Hydration can prepare tert butyl alcohol, further produce spices and be used as solvent; Disproportionation can prepare neohexene and further produce spices; Preparation of triisobutyl aluminum, isovaleraldehyde and isoamyl alcohol; A super absorbent polymer can be prepared by reaction with maleic anhydride. It can be used to produce surfactant, butyl resin, dispersant, etc.

Cetane is an alkane with the chemical formula C16H34. Cetane is composed of 16 carbon atoms in a straight chain. The head and tail are connected by three hydrogen atoms, with two in the middle. Cetane number is used to measure the flammability of diesel fuel. Cetane is very flammable under compression. Therefore, cetane number of cetane is 100, which can be used as a reference for other fuels. Cetane is one of the fuels with the lowest octane number, which is less than − 30.
