What is 2-Phenyl-1-propene?
2-Phenyl-1-propene, also known as α-methylstyrene (abbreviated as a-MS or AMS) or phenylisopropene, is a by-product of the production of phenol and acetone by the cumene method, generally a by-product of phenol per ton 0.045t α-MS.
2-Phenyl-1-propene is a colorless liquid with a pungent odor. The molecule contains a benzene ring and an alkenyl substituent on the benzene ring. It is prone to polymerization when heated. 2-Phenyl-1-propene can be used in the production of coatings, plasticizers, and as a solvent in organic synthesis.
- 2-phenyl-1-propene can be used in the production of coatings, plasticizers and also as a solvent.
- 2-phenyl-1-propene is used as a polymer monomer, such as toluene-butadiene rubber and high temperature plastics. It can also be used to prepare coatings, hot melt adhesives, plasticizers and synthetic musk.
- In Japan, 90% of α-methylstyrene is used as a modifier for ABS resin, and the rest is used as a solvent and raw material for organic synthesis.
- 2-phenyl-1-propene was used in organic synthesis. polymerized monomers.

The synthetic route of 2-phenyl-1-propene
Synthesis path 1
Taking cumene as starting material, cumene is oxidized, with cumene hydrogen peroxide stream, under the situation of not concentrating the cumene hydrogen peroxide stream, at least a part is separated, and selectively in precious metal A hydrogenation reaction is carried out in the presence of a catalyst to prepare cuminol, the reactant containing the cuminol is concentrated, and a dehydration reaction is carried out in an acidic environment to prepare 2-phenyl-1-propene.
Synthesis path 2
2-Phenyl-1-propene is recovered from the phenol residue. Its device diagram is shown in the figure below. The phenol residual liquid is added to the raw material storage tank, and the phenol residual liquid is transported to the tower kettle through the pipeline through the power of the power pump. Benzene and 2-phenyl-1-propene are transported to the condenser through the reaction column, liquefied under the action of the condenser, transported to the reflux tank through pipelines, and transported to the reaction column and A tank at a ratio of 5:1 respectively , continue to heat to 250 ° C to separate out phenol and acetophenone, transport it to the condenser through the reaction tower, liquefy it under the action of the condenser, transport it to the reflux tank through the pipeline, and transport it to the reaction tank at a ratio of 5:1. tower and tank B.
The cumene and 2-phenyl-1-propene in the A tank are transported to the tower still through pipelines, and under the action of the heater, the components in the tower still are heated to separate 2-phenyl-1-propene, It is transported to the condenser through the reaction tower, liquefied under the action of the condenser, transported to the reflux tank through the pipeline, and transported to the reaction tower and the A tank in a ratio of 5:1 respectively, and the product is collected from the A tank.
Application of 2-Phenyl-1-Propene in Organic Synthesis
α-MS is the basic raw material for organic synthesis and can be used to synthesize cumene, dicumyl peroxide, p-cumylphenol, etc. α-MS hydrogenation to produce cumene was industrialized in 1980, using palladium/aluminum catalyst, the reaction was carried out in a trickle bed reactor, the conversion rate of α-MS was greater than 99%, and the by-products were very few, so the cumene was It can be directly returned to the phenol acetone production line.
Synthesis of dicumyl peroxide (DCP) by α-MS and cumene hydrogen peroxide (CHP) is another process route for DCP synthesis. Using phenol as a catalyst, the reaction temperature is 15 to 45 ° C, and the synthesis of DCP is carried out in one step. Compared with the traditional benzyl alcohol process, the reduction, water washing, and concentration processes for preparing benzyl alcohol can be omitted. The reaction formula is shown in the following figure. The p-cumyl phenol synthesized by α-MS and phenol under the action of acid catalyst is the raw material for synthesizing thermoplastics and polycarbonate.
