Abstract: The invention provides a process for the manufacture of acetic acid, acetic aldehyde and ethanol by reaction in the gaseous phase of carbon monoxide and hydrogen in the presence of catalysts containing rhodium and optionally promoters, at elevated temperature and pressure. In this process, the temperature is raised in the starting phase, where the catalyst is heated to the working temperature TR intended for continuous operation, in a range of from TO to TR, TO being 75 DEG to 125 DEG C. below TR, continuously or in steps of 10 DEG C. at most, in a period of time of from 100 to 1,000 hours; the temperature being raised by 10 DEG C. at most within any 10 hour interval.

Abstract: The invention relates to a process for the preparation of an ethyl ester from ethanol-containing mixtures of aliphatic alcohols, which comprises esterifying the alcohols with a carboxylic acid in the presence of an acid catalyst in a distilling column and separating in the same column the ethyl ester continuously from the ester mixture obtained. To this purpose, the alcohol mixture is introduced into the sump and the carboxylic acid is introduced into the column at a point located in the central part and the ethyl ester as well as the water formed during esterification are withdrawn continuously at the top of the column and the higher esters are withdrawn continuously at the sump.

Abstract: The invention relates to a process for the isomerization of halogenated thiophenes on zeolite catalysts. In this manner, in particular, 2-chlorothiophene is isomerized to 3-chlorothiophene and 2-bromothiophene is isomerized to 3-bromothiophene. Particularly suitable zeolites are synthetic zeolites of the pentasil, mordenite or faujasite type in their acid form.
