| titleOfInvention | A kind of preparation method of quadripolymer diesel pour inhibitor |
| abstract | The invention discloses a kind of preparation method of quadripolymer diesel pour inhibitor, at least comprise the following steps：A, under solvent condition, using methacrylic acid and higher alcohol as raw material, using p-methyl benzenesulfonic acid as catalyst, prepare methylacrylic higher alcohols ester；B, under solvent condition, using maleic anhydride and higher alcohol as raw material, using p-methyl benzenesulfonic acid as catalyst, maleic anhydride high-carbon alcohol ester is made；C, under solvent condition, using methylacrylic higher alcohols ester, maleic anhydride high-carbon alcohol ester, vinylacetate and acrylamide as monomer, add initiator, be prepared into quadripolymer diesel pour inhibitor.The beneficial effects of the invention are as follows：Existing homopolymer pour-point depressant is substituted using quadripolymer pour-point depressant, the depression effeCt of quadripolymer pour-point depressant is significantly better than the homopolymer pour-point depressant of single composition. |
