Processes for preparing or recovering acetals or ketals by means of pervaporation |
| abstract |
The process of the present invention comprises reacting an aldehyde or ketone with an alcohol in the presence of a solid acid, and removing removing water and methanol from the reaction product by pervaporation, characterized in that a membrane having a flux density for water of 0.04 to 2.8 kg/(hm 2 ) is used to remove the water and another membrane having a flux density for methanol of 2.0 to 100 kg/(hm 2 ) is used to remove the methanol. |
