Abstract: The present invention relates to a nitrogen-containing diesel solidification point depressant composition, and preparation and application thereof. The nitrogen-containing diesel solidification point depressant composition includes the following components in percentage by weight: 10-40% of monoisopropanolamine; 10-40% of cyclohexane; 0-20% of polyethylene glycol; and 40-60% of N-tetradecyl methacrylamide-tetradecyl methacrylate. After the prepared diesel solidification point depressant composition is added to commercially available 0 #diesel, a solidification point and a cold filter plugging point of the diesel are respectively depressed by 21-25° C. and 9-13° C.

Abstract: The present invention relates to a nitrogen-containing terpolymer biodiesel solidification point depressant, and a preparation method and application thereof. The preparation method includes the following steps: 1) respectively preparing methylacrylic acid high carbon ester and N-hexadecyl methacrylamide; 2) adding the methylacrylic acid high carbon ester, the N-hexadecyl methacrylamide, and vinyl acetate to a solvent, and adding an initiator for polymerization to yield a methylacrylic acid high carbon ester-N-hexadecyl methacrylamide-vinyl acetate terpolymer, i.e., a nitrogen-containing terpolymer biodiesel solidification point depressant. Compared with the prior art, the nitrogen-containing terpolymer biodiesel solidification point depressant of the present invention solves the problem of poor compatibility of single methylacrylic acid depressants, N-hexadecyl methacrylamide and vinyl acetate are introduced to extend the composition of the depressant and improve a solidification point depression effect, the preparation process of the depressant is simple, and the experimental operation is convenient.
