DEPRESSANT FOR PETROLEUM PRODUCTS

petroleum products technology. SUBSTANCE: depressant is prepared by interaction of higher fatty alcohols fraction C12-C18, pyromellite dianhydride, and ethylene glycol at molar ratio (3.0-1.5) : (1.0 : (0.5-2.0). When 0.5-2,0 wt % of depressant is added to diesel fuel with freezing temperature +11 C...

Zusammenfassung:	petroleum products technology. SUBSTANCE: depressant is prepared by interaction of higher fatty alcohols fraction C12-C18, pyromellite dianhydride, and ethylene glycol at molar ratio (3.0-1.5) : (1.0 : (0.5-2.0). When 0.5-2,0 wt % of depressant is added to diesel fuel with freezing temperature +11 C, depression of freezing temperature varies between 14 and 28 C (with old depressants does not exceed 1-2 C). EFFECT: drastically increased depression activity. 2 tbl
