One, acerbity — is alkaline two footwork: This is the most conventional technology also be the technological process with the general commonly used business that develops a technology independently at present; Its advantage is specific power consumption low, those who master is very OK and true avoid distillation, technical reference material is more also; Defect is to should pass acerbity — to be changed alkalinely, the requirement such as the acid value of the stock after be being changed to ester, impurity, water is stricter, incidental saponification, liquid waste amount is larger.
2, detached reaction law: Also a lot of enterprises use this below not self-conscious circumstance, main train of thought is to use first distillation (strip) the method of detached fatty acid, realize fatty acid and the physical depart with oily neutral first, use the idea that ester is changed and alkaline catalysis ester exchanges to have reaction respectively in the light of fatty acid and neuter oil after that, get unified armour ester. The advantage of this law is craft simple, master easily, the sale of the product is quicker; Defect is specific power consumption big, equipment demand is high (especially anti-corrosive) .

  3, law of completely acerbity catalysis: This is oneself also be the method that a few enterprises use, the advantage is low to raw material requirement, can handle basic and all raw material, used blame bath technology; Defect is specific power consumption tall (in 3 kinds of methods the 2nd) , what ester turns equipment is anti-corrosive the demand is high.
  4, need is additional be, acerbity catalysis law agrees with especially vegetable crude oil, the petroliferous crop such as the Ma Feng tree of popular to be in at present development, the crude oil that squeezes need not be passed purificatory, enter acerbity catalysis directly. And traditional alkaline catalysis needs to pass strict purificatory ability to enter catalytic technological process. #p#·ÖÒ³±êÌâ#e#
