| description | Méthode de préparation de produits de réaction du phosgène et de diphénol dans des conditions de réaction d'interface. Le diphénol tel que le diphénol-A est introduit dans le réacteur sous la forme d'une suspension stable qui réduit l'hydrolyse du phosgène, réduit à un minimum les pertes en phosgène et permet d'améliorer le dosage du diphénol-A introduit dans le réacteur.
A method is provided for making reaction products of phosgene and dihydric phenol under interfacial reaction conditions. The dihydric phenol such as BPA is introduced into the reactor in the form of a stable suspension which reduces phosgene hydrolysis, minimizes phosgene escape and effects improved BPA metering into the reactor. |
