Abstract
(EN)
The present inventions relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol. Especially, the present invention relates to the preparation of 3,3,5- trimethylcyclohexylidene bisphenol from 3,3,5-trimethylcyclohexanone and phenol in the presence of a gaseous acidic catalyst. The preparation comprises a first drying step and a second drying step wherein in the second drying step the temperature is increased in comparison to first drying step or in the second drying step the pressure is lowered in comparison to first drying step, or in second drying step both the temperature is increased and the pressure is lowered in comparison to the first drying step (d1).
(FR)
La présente invention concerne la préparation du 3,3,5-triméthylcyclohexylidène bisphénol. En particulier, la présente invention concerne la préparation de 3,3,5-triméthylcyclohexylidène bisphénol à partir de 3,3,5-triméthylcyclohexanone et de phénol en présence d'un catalyseur acide gazeux. La préparation comprend une première étape de séchage et une seconde étape de séchage, dans la seconde étape de séchage, la température étant supérieure à celle de la première étape de séchage ou dans la seconde étape de séchage, la pression étant inférieure à celle de la première étape de séchage, ou dans la seconde étape de séchage, à la fois la température étant supérieure et la pression étant inférieure à celles de la première étape de séchage (d1).
