20110196176 | PROCESS FOR THE PREPARATION OF M-SUBSTITUTED ALKYLTOLUENES BY ISOMERIZATION WITH IONIC LIQUIDS AS CATALYSTS - The invention relates to a process for the preparation of m-substituted alkyltoluenes of the formula (I) | 08-11-2011 |
20110257426 | PROCESS FOR PREPARING CARBOXYLIC ESTERS BY REACTIVE DISTILLATION - In a process for preparing carboxylic esters by transesterification, a first feed stream comprising a first carboxylic ester, e.g. methyl formate, is introduced laterally into a reaction column at least one first feed point located between top and bottom of the reaction column and a second feed stream comprising a first alcohol, e.g. ethanol, is introduced laterally into the reaction column at a second feed point located above the first feed point and are reacted in a reaction zone of the reaction column to form a second carboxylic ester and a second alcohol. The first alcohol has a higher molecular weight than the second alcohol. A product fraction comprising the second carboxylic ester and unreacted first carboxylic ester is taken off at an offtake point located above the second feed point. At the bottom of the reaction column, a bottom fraction comprising the second alcohol and unreacted first alcohol is taken off. The product fraction is separated by distillation at a pressure which is different from the pressure in the reaction column into second carboxylic ester and a fraction comprising unreacted first carboxylic ester and the fraction comprising unreacted first carboxylic ester is at least partly recirculated to the reaction zone. | 10-20-2011 |
20110257427 | PURIFICATION OF CARBOXYLIC ESTERS BY EXTRACTIVE DISTILLATION - In a process for purifying carboxylic esters such as ethyl formate, a carboxylic ester to be purified is distilled in the presence of an extractant, preferably by (a) allowing vapor of the carboxylic ester to be purified to ascend in a distillation column; (b) conveying the extractant in countercurrent to the vapor in an extractive distillation column; (c) taking off pure carboxylic ester above the extractive distillation zone. The extractant is, for example, selected from among diols, polyols, open-chain or cyclic amides. | 10-20-2011 |
