PROCESS FOR PRODUCING BISPHENOL A

摘要

A process for producing bisphenol A with the use of a horizontal belt filter, the horizontal belt filter used for solid-liquid separation of slurry formed by crystallization of bisphenol A/phenol adduct from a phenol solution of bisphenol A obtained by carrying out reaction between phenol and acetone in the presence of an acid catalyst, wherein the horizontal belt filter is fitted with a filter cloth of 50 to 100 ml/cm2.sec air permeability obtained by weaving a yarn of uniform diameter, which filter cloth realizes prolongation of filter cloth lifetime and exhibiting of stable filtration performance.
