METHOD OF PREPARING DEPRESSANT FOR PETROLEUM PRODUCT

fuel and lube oil technology. SUBSTANCE: synthetic fatty acids C21-C25 fraction, pentaerythritol, and phthalic anhydride are brought into interaction followed by condensation with polyethylenepolyamines at molar ratio 2.0 : 1.0 : (1.0- 1.5) : (0.1-2.0), respectively. Freezing point of petroleum prod...

Zusammenfassung:	fuel and lube oil technology. SUBSTANCE: synthetic fatty acids C21-C25 fraction, pentaerythritol, and phthalic anhydride are brought into interaction followed by condensation with polyethylenepolyamines at molar ratio 2.0 : 1.0 : (1.0- 1.5) : (0.1-2.0), respectively. Freezing point of petroleum products with resulting depressant is lowered by 6 to 13 C. EFFECT: increased depressant activity. 2 tbl
