Abstract
Procédé pour la préparation d'un lit fixe d'une résine échangeuse de cations partiellement neutralisée ayant une multiplicité de groupes acide sulfonique et une multiplicité de groupes acide sulfonique neutralisés par une mercaptoamine, où les groupes neutralisés sont distribués d'une manière sensiblement uniforme sur la résine. a. On remplit ou on remplit partiellement un réacteur avec une résine échangeuse de cations acide sulfonique de manière à former un lit fixe de résine non neutralisée; b. On fait passer dans le réacteur une solution d'une marcaptoamine, ou d'un progéniteur de marcaptoamine, en quantité suffisante pour obtenir le degré désiré de neutralisation partielle de la résine, de manière à former des groupes neutralisés qui ne sont pas distribués de manière sensiblement uniforme sur la résine; et c. On fait passer un liquide à travers le lit fixe de résine pendant un temps suffisant pour distribuer de manière sensiblement uniforme les groupes neutralisés sur la résine. Application à la preparation de bisphénols.A process for the preparation of a fixed bed of a partially neutralized cation exchange resin having a multiplicity of sulfonic acid groups and a multiplicity of sulfonic acid groups neutralized by a mercaptoamine, wherein the neutralized groups are distributed in a substantially uniform manner across resin. at. A reactor is filled or partially filled with a sulfonic acid cation exchange resin so as to form a fixed bed of non-neutralized resin; b. A solution of a marcaptoamine, or progenitor of marcaptoamine, in an amount sufficient to achieve the desired degree of partial neutralization of the resin, is passed through the reactor so as to form neutralized groups which are not distributed in such a manner. substantially uniform over the resin; and c. A liquid is passed through the fixed resin bed for a time sufficient to distribute the neutralized groups substantially uniformly on the resin. Application to the preparation of bisphenols.
