Abstract
Abstract A distillate fuel having improved cold flow containing a low molecular weight product obtained on reacting an allyl halide and a C10 to C20 olefin using an aluminum halide as a catalyst, the molar ratio of allyl halide to olefin being from 5:1 to 1:10. This reaction product is characterized by having a molecular weight of from about 550 to about 1,200. A suitable allyl halide is allyl chloride; suitable olefins are decene, dodecene, tetradecene, heptadecene, octadecene and the like.
