Abstract
Process for the preparation of aldehydes by catalytic gas phase hydrogenation of carboxylic acid or their derivatives with the aid of a tin catalyst The invention relates to a process for the preparation of aldehydes by catalytic gas phase hydrogenation of carboxylic acids or carboxylic acid derivatives at elevated temperature, which comprises employing at tin catalyst supplied to an oxidic support material.
Claims22
A process for the preparation of an aldehyde by catalytic gas phase hydrogenation of a carboxylic acid or carboxylic acid derivative, the derivative selected from the group consisting of esters, acid anhydrides, acid chlorides and acid bromides, at elevated temperature, which comprises the steps of:
- applying a tin catalyst to an oxidic support material to form a catalyst, and
- hydrogenating the carboxylic acid or carboxylic acid derivative in the presence of the catalyst.
