Title:
LOW SULFUR DIESEL BLOCKAGE INHIBITOR, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/134602
Kind Code:
A1
Abstract:
A low sulfur diesel blockage inhibitor as shown in formula (I), a preparation method therefor, and use thereof. In formula (I), x and y are each an integer between 0 and 4; m and n are each an integer between 3 and 9, and 10≤m+n≤14; R1 and R2 are each selected from H, a C1-C6 linear or branched alkyl group, or a C3-C6 cycloalkyl group. By using a vegetable oil as a raw material, a modified vegetable oil fatty acid is first obtained, and then a polar group of an unsaturated dialdehyde with a certain chain length is introduced into a molecular chain of the modified vegetable oil fatty acid. The obtained product can better solve the problem of the blockage of an engine filter nozzle, reduce the number of engine failures, improve the service life of an engine, and reduce the usage amount of a blockage inhibitor.
