CATALYST FOR DEALCOHOLIZATION CONDENSATION REACTION AND METHOD FOR PRODUCING ORGANOPOLYSILOXANE USING THE SAME |
摘要 |
In the present invention, when an organopolysiloxane is produced by a dealcoholization condensation reaction between a silicon atom-bonded hydroxy group and a silicon atom-bonded alkoxy group, a quaternary ammonium ion-containing compound such as an alkylammonium hydroxide compound or a silanolate thereof is used as a catalyst. The catalyst for the dealcoholization condensation reaction of the present invention is easily removed after use and is stable. For this reason, when an organopolysiloxane is produced using the aforementioned catalyst, it is not necessary to use complicated production steps or a large amount of the catalyst. |
