Butylene oxide is an important raw material for chemical production, with unique properties and a wide range of uses. This article will detail the properties of butylene oxide, production methods, uses and safety knowledge.
1. the nature of epoxy butane
epoxy butane is a colorless transparent liquid, similar to the smell of ether. Its molecular formula is C4H8O, and its structure contains epoxy groups, so it has high chemical activity. Butylene oxide has a boiling point of 34.6 ℃, a flash point of -23 ℃, and a density of 0.806g/cm3. It is insoluble in water and soluble in organic solvents such as alcohol and ether. In addition, butylene oxide also has flammable, explosive, toxic and other characteristics, so special attention should be paid to safety during use. The production method of
2. butylene oxide
butylene oxide has two main production methods: one is obtained by the reaction of butene and hydrogen peroxide, and the other is obtained by dehydrogenation cyclization of butanol. Among them, the former process is more commonly used, mainly butene and hydrogen peroxide in the acidic catalyst under the epoxidation reaction, the formation of butylene oxide and water.
3. the use of butylene oxide
butylene oxide as an important chemical raw material, widely used in various fields. The following are its main uses:
1. Preparation of rubber accelerator
epoxy butane can be used as the main raw material of rubber accelerator, used in the production of accelerator M, DM, CZ, etc., these accelerators in the rubber processing process can improve the vulcanization speed and vulcanized rubber strength, toughness and other properties.
2. production of ethylene glycol
the reaction of epoxy butane and water to produce ethylene glycol, ethylene glycol is an important organic chemical raw materials, can be used in the production of polyester fibers, antifreeze, solvents and so on.
3. Preparation of other chemicals
Butylene oxide can also be used to produce butanediol, γ-butyrolactone, 1,4-butanediol and other chemicals, these compounds are widely used in medicine, pesticides, plastics and other fields.
4. the safety
of butylene oxide
Because butylene oxide has flammable, explosive, toxic and other characteristics, it is necessary to strictly abide by the safety operation procedures in the production process to ensure production safety. In addition, when using butylene oxide, care should be taken to avoid contact with open flames, high heat, etc. to prevent fire and explosion accidents. At the same time, contact with skin and eyes should be avoided to avoid irritation and damage.
In conclusion, as an important raw material for chemical production, butylene oxide has a wide range of applications. In the process of use, we should fully understand its nature and safety requirements, and strictly abide by the operating procedures to ensure the safety of production and use.
