Abstract：
 This is the craft method of preparing biological diesel oil by using the coupling technology in reaction separating course. It relates to the new craft of preparing biology diesel oil (fatty diethylene glycol dinitrate) through the ester exchange reaction of vegetable oil and higher alcohols, and belongs to chemical industry craft technology field. It includes: the ester exchange reaction of vegetable oil and higher alcohols; the separation of product fatty diethylene glycol dinitrate, glycerol and reaction mixed liquid; the separation of product fatty diethylene glycol dinitrate, glycerol and higher alcohols; the separation of fat diethylene glycol dinitrate and glycerol; the condensation backflow of fatty alcohol; and the separation of glycerol. It makes the circumvolving higher alcohols carry out the product fatty diethylene glycol dinitrate and glycerol through higher reaction temperature, and realizes the separation of outcome and reactant; the non-homogeneous phase catalyst stays in the actor, and don't need to have following process to the catalyst. The invention realizes the coupling of reaction and separation courses, speeds up the speed of non-homogeneous phase reaction, and avoids the problem of the following process to catalyst in the homogeneous phase process. Besides it can save production cost, and improves the producing performance of biology diesel oil.
