Title
(EN) MANUFACTURE OF BISPHENOL A
(ZH) 双酚A的制备
Abstract
(EN)
The invention is directed to a method for the manufacture of bisphenol A, to the use of acid in a method for crystallisation of bisphenol A/phenol adduct, and to bisphenol A/phenol adduct crystals. The method for the manufacture of bisphenol A comprises: a) reacting phenol and acetone in the presence of an acidic catalyst to form a product mixture comprising bisphenol A; and b) crystallising a bisphenol A/phenol adduct from said product mixture, wherein said crystallisation is carried out in the presence of an acid, wherein the total amount of acid present during the crystallisation step is 5% or less by total weight of the reaction product.
