| titleOfInvention | Low-acid low-sulfur diesel lubricity improver and preparation method thereof |
| abstract | The invention relates to a low-acid low-sulfur diesel lubricity improver and a preparation method thereof, which comprises the steps of mixing unsaturated monoamide and a polymerization inhibitor at 180 ℃ for gradually adding eleostearic acid, continuing to react for a certain time at 240 ℃ for 200 ℃ after the addition is finished, and obtaining an improver product through reduced pressure distillation. The low-acid lubricity improver is prepared from unsaturated monoamide and eleostearic acid, has the advantages of good lubricity, low freezing point, low acid value, small using amount and detergent effect, and can enable low-sulfur diesel to meet national V lubricity standard and freezing point requirements after blending. |
