Abstract
PURPOSE: A fluidity improver for a hydrocarbon type fuel oil, capable of lowering extremely a cold filter plugging point, comprising a partial ester of a polyhydric alcohol such as trimethylolethane with behenic acid.
CONSTITUTION: (A) One or more polyhydric alcohols selected from trimethylolethane, trimethylolpropane, pentaerythritol, and dipentaerythritol are esterified with (B) behenic acid, to give a partial ester wherein ≥0.5 (preferably ≥1 on average) hydroxyl group of the component A per molecule on average is left. 10W5,000ppm (preferably 50W1,000ppm) of the ester is added to a fuel oil.
EFFECT: The pour point of fuel oil is lowered, storage properties and transportation properties are improved, and even a high-boiling fraction is made usable, to improve productivity.
