Title (EN) METHOD FOR PREPARING HYDROXYAROMATIC CHLOROFORMATES
(FR) PROCEDE DE PREPARATION DE CHLOROFORMIATES HYDROXYAROMATIQUES
Abstract: front page image
(EN)This invention relates to a process for the preparation of hydroxyaromatic chloroformate products suitable for use as chainstopping or endcapping agents. The process involves a semi-batch process in which an aqueous caustic solution is introduced into a vessel comprising a precharge solution, and careful control of the overall molar ratios of phosgene, caustic and hydroxyaromatic compound are maintained.
(FR)L'invention concerne un procédé de préparation de produits à base de chloroformiates hydroxyaromatiques pouvant être utilisés comme agents d'arrêt de chaîne (chainstopping) ou de coiffage d'extrémité (endcapping). Ce procédé comprend une opération semi-continue consistant à introduire une solution caustique aqueuse dans un récipient contenant une solution de précharge, une régulation précise des rapports molaires totaux de phosgène, de caustique et de composé hydroxyaromatique étant assurée.
