| Abstract |
The present invention provides an improved process for the preparation of lubricants from vegetable oil or fat obtained from animal source. The present invention involves a reaction of vegetable oil or fat with an alcohol in the presence of a double metal cyanide catalyst at a temperature in the range of 150° to 200°C for a period of 3 6 hrs to obtain the desired bio lubricant.
1. The process described above has the combined unique advantages of high conversion accompanied with high selectivity for lubricants.
2. The catalyst can be easily separated from the product mixture and no issues related to soponification are encountered.
3. The catalyst of the present invention is highly efficient for the preparation of lubricants from vegetable oil or fats and C6 C8 alcohols. |
