What is TRANS-BETA-METHYLSTYRENE?
Chemical properties
clear colourless to very faintly yellow liquid
The Uses of TRANS-BETA-METHYLSTYRENE
Trans-β-methylstyrene was used in the epoxidation reaction of an oxidant solution with a solution of dichloromethane, where nickel is used as a catalyst and benzyltributylammonium bromide as a phase-transfer agent.
General Description
The product exhibits potential exothermic hazards at higher temperatures.
Purification Methods
Distil it under N2 from powdered NaOH through a Vigreux column (p 11), and pass it through activated neutral alumina before use [Wong et al. J Am Chem Soc 109 3428 1987]. [Beilstein 5 III 1184, 5 IV 1359.]
