摘要:
The present invention relates to a method for separating a salified phenolic compound from a reaction medium including same. The method of the invention for separating salified phenolic compounds from an aqueous reaction medium resulting from the reaction of a phenolic compound and glyoxylic acid in the presence of a base, which leads to a reaction medium including at least the excess of the starting salified phenolic compound and the various salified mandelic compounds resulting from the reaction, is characterized in that said reaction medium containing the starting salified phenolic compound is contacted with an adsorbent substrate, which leads to the selective adsorption of said phenolic compound onto said substrate and to the recovery of an aqueous flow containing the salified mandelic compounds from the reaction, and in that the phenolic compound attached onto the adsorbent is desorbed by means of a regenerating treatment of said adsorbent

摘要:
A process for the production of bifunctional phenylene ether oligomers represented by the general formula (1) which are free from amine adducts, which comprises conducting oxidation polymerization of a divalent phenol with a monovalent phenol by the use of a copper catalyst, and a tertiary amine, a secondary amine having a secondary or tertiary alkyl group or an aryl group, or a mixture of both: (1) wherein R , R , R , R , R , R and R are each independently halogeno, alkyl having six or fewer carbon atoms, or phenyl; R , R , R , R and R are each independently hydrogen, halogeno, alkyl having six or fewer carbon atoms, or phenyl; and m and n are each an integer of 0 to 25, with the proviso that at least either is not 0.
