Method for preparing spirobiindane bisphenols |
摘要 |
Spirobiindane bisphenols are prepared by contacting a mixture of a bisphenol or a 4-isopropenylphenol and a 1-(4-hydroxyphenyl)indanol with a metal halide Lewis acid or an alkanesulfonic acid. High purity spirobiindane bisphenols may be prepared by employing a purification sequence, which preferably includes a step of precipitation of the product with water from a methanol-methylene chloride solution.
