Popis:	A property of biodiesel that currently restricts its use to blends of 20% or less is its relatively poor low-temperature properties (cloud point). Alkoxylation of the unsaturated fraction of biodiesel offers the potential benefit of reduced cloud point without compromising ignition quality or oxidation stability. In addition, the butoxylation of butyl biodiesel improves the renewable nature of biodiesel by substituting fossil-derived methanol with biobutanol. Butyl biodiesel derived from canola oil was epoxidized via the in situ peroxyacetic acid method for 6 h, resulting in a conversion of 46% of the unsaturated esters. Epoxy butyl biodiesel was butoxylated with n-butanol with sulfuric acid catalyst without the use of solvents. Conversion and selectivity for butoxy butyl biodiesel were optimized by examining reaction conditions including: temperature, reaction time, catalyst concentration, and molar ratio of alcohol to epoxy biodiesel. The optimal conditions for the butoxylation of epoxy butyl biodiesel ...
