Title:
NITROGEN-CONTAINING TERNARY POLYMER BIODIESEL POUR POINT DEPRESSANT, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/244388
Kind Code:
A1
Abstract:
The present invention relates to a nitrogen-containing ternary polymer biodiesel pour point depressant, a preparation method therefor and an application thereof. The preparation method comprises the following steps: 1) respectively preparing methacrylic acid high-carbon ester and N-hexadecyl methacrylamide; and 2) adding methacrylic acid high-carbon ester, N-hexadecyl methacrylamide, and vinyl acetate to a solvent, and then adding an initiator, and performing a polymerization reaction to obtain a methacrylic acid high-carbon ester-N-hexadecyl methacrylamide-vinyl acetate ternary polymer, i.e., a nitrogen-containing ternary polymer biodiesel pour point depressant. Compared with the prior art, the nitrogen-containing ternary polymer biodiesel pour point depressant in the present invention solves the problem of poor broad spectrum of a single methacrylic acid pour point depressant. The introduction of N-hexadecyl methacrylamide and vinyl acetate expands the composition of the pour point depressant, and improves the pour point depression effect. Moreover, the pour point depressant is simple in preparation process and convenient in experimental operation.
