Method for producing α-methylstyrene and heat-resistant styrene-based copolymer using the α-methylstyrene |
| abstract |
An object of the present invention is to provide highly pure α-methylstyrene by efficiently removing polar substances present in the α-methylstyrene. The present invention discloses a method for purifying α-methylstyrene by reacting polar substances contained in the α-methylstyrene in the presence of a basic substance, and separating a reaction product of the polar substance and the α-methylstyrene. |
