Abstract
The invention relates to the preparation of low-viscosity ester mixtures for transesterification of vegetable or animal fats or oils with monofunctional esters.
Claims
exact text as granted — not AI-modified1 . A process for preparing ester mixtures comprising reacting triglycerides with alkyl or cycloalkyl esters of aliphatic or cycloaliphatic monocarboxylic acids.
2 . The process of claim 1 , wherein said triglycerides are triesters of glycerol with C6- to C22-carboxylic acids.
3 . The process of claim 2 , wherein said triesters of glycerol are free of OH groups and have 6 or less olefinic double bonds.
4 . The process of claim 1 , wherein said alkyl or cycloalkyl esters are free of OH groups.
5 . The process of claim 1 , wherein said alkyl or cycloalkyl esters are linear or branched alkyl esters of monofunctional aliphatic carboxylic acids.
6 . The process of claim 1 , wherein said alkyl or cycloalkyl esters are butyl acetate, ethyl propionate, or mixtures thereof.
7 . The process of claim 1 , wherein said process is carried out in the presence of at least one catalyst.
8 . An ester mixture prepared by the process of claim 2 .
9 . The ester mixture of claim 8 , wherein said ester mixture has a shear viscosity of 12 to 50 mPa·s at 23° C. and solidification points below 0° C.
10 . A solvent comprising the ester mixture of claim 8 .
11 . An auxiliary comprising the ester mixture of claim 8 .
12 . A process agent comprising the ester mixture of claim 8 .
13 . A fuel for internal combustion engines comprising the ester mixture of claim 8 .
14 . A solvent comprising the ester mixture of claim 9 .
15 . An auxiliary comprising the ester mixture of claim 9 .
16 . A process agent comprising the ester mixture of claim 9 .
17 . A fuel for internal combustion engines comprising the ester mixture of claim 9 .Join the waitlist — get patent alerts
