A kind of method for preparing organosilicon biological lubricating oil base oil |
| abstract |
The invention relates to a method for preparing organosilicon bio-lubricating oil base oil by taking vegetable oil as raw material through epoxidation of fatty acid ester and direct ring-opening modification of organosilicon, comprising the following steps: performing transesterification reaction between vegetable oil and alcohol to obtain fatty acid Esters; fatty acid esters are added to urea-methanol saturated solution and separated by urea inclusion method to obtain unsaturated fatty acid esters; unsaturated fatty acid esters react with organic acids and acidic catalysts to obtain epoxy fatty acid esters; epoxy fatty acid esters Under the action of an organic base, the organosilicon lubricating oil base oil is obtained by direct ring-opening of the organosilicon. The method has mild conditions, high reaction efficiency, few by-products in the reaction process, and no harmful substances in the production process. The prepared organic silicon bio-lubricating oil base oil has a low pour point, good viscosity-temperature performance, large viscosity index, and low oxidation resistance. Good stability and good anti-wear performance. |
