MANUFACTURING METHOD FOR POLYCARBONATE

A method for manufacturing polycarbonate by melt-polycondensing bisphenol and carbonic acid diester uses as catalyst an alkali metal compound and/or alkaline earth metal compound (a). The catalyst is added to the bisphenol prior to the melt polycondensation, in an effective amount, i.e., the amount of alkali metal compound and/or alkaline earth metal compound (a) that acts effectively as a catalyst, is contained in said bisphenol, and is controlled to have the same catalytic activity as 1×10?8 to 1×10?6 mole of bisphenol disodium salt per mole of pure bisphenol A. The method conducts the reaction efficiently from the initial stage in a stable manner to obtain polycarbonate with good color, good heat stability and color stability during molding and the like.

Process for the purification of bisphenols and preparation of polycarbonates therefrom

A phenol and a ketone are reacted to form bisphenol, and the liquid bisphenol obtained or a mixed solution of said solution and a phenol is filtered through a calcined metal filter to obtain bisphenol which makes it possible to efficiently obtain bisphenol which either does not contain fine particulate impurities or contains such impurities only in minute amounts, and a method for manufacturing polycarbonate using bisphenol obtained bythis method. The filtration grade of the calcined metal filter should be 1.0 μm or less. After filtering, the calcined metal filter can be backwashed or chemically washed and then reused. The bisphenol should preferably be bisphenol A.

REACTION OF PHENOL WITH 1-OCTYNE IN THE PRESENCE OF ALUMINUM PHENOLATE

The reaction of phenol with 1-octyne in the presence of aluminum phenolate leads to a mixture of the corresponding 2,2-di(hydroxyphenyl)octanes and substituted chromans and chromenes.At temperatures above 160 deg C 2- and 4-(2-octyl)phenols are also forme
