Results fractional distillation methyl ethers of fat acids of rape and sunflower oils (МERO, RME and МESO) on a method of GOST 2177-82 are resulted. For the first time the received curves разгонки domestic biofuel allow to calculate characteristic temperatures and corners of an inclination of curves distillation, to determine it heating properties. The size of a difference of temperatures between boiling ethers and their pairs is experimentally established. The received results will well be coordinated to the data distillation Polish ether EMKOR. It is known, that methyl ethers of fat vegetable acids are applied as fuel to diesel engines [1]. Set of physical parameters of the fuel causing speed and completeness of process of evaporation, ability to education топливовоздушной mixes in the cylinder of the engine is estimated by an integrated parameter - испаряемостью fuel. Intensity and completeness of evaporation of fuel depends on his{its} physical properties, parameters of an air charge, such as the engine, a design of the chamber of combustion and the fuel equipment
