Description

technical field [0001] The invention relates to the field of plasticizer reactor equipment, in particular to a reactor for chloromethoxy fatty acid methyl ester. Background technique [0002] Chloromethoxy fatty acid methyl ester is also known as a new type of environmentally friendly plasticizer. As an important multi-purpose product, plasticizer plays an important role in social development. This product is made of natural oil and alcohol after lipid exchange reaction, and then A kind of product with higher molecular weight produced by chlorination reaction, good compatibility with PVC, excellent plasticizing effect, flame retardant, non-toxic, environmental protection, because this product has an ester structure, it can replace octyl phthalate Esters and butyl esters are used as plasticizers, and they also contain chlorinated paraffin, which can replace chlorinated paraffin and improve the flame retardancy and electrical insulation of the product. The optimized type I pro...

[0002] Chloromethoxy fatty acid methyl ester is also known as a new type of environmentally friendly plasticizer. As an important multi-purpose product, plasticizer plays an important role in social development. This product is made of natural oil and alcohol after lipid exchange reaction, and then A kind of product with higher molecular weight produced by chlorination reaction, good compatibility with PVC, excellent plasticizing effect, flame retardant, non-toxic, environmental protection, because this product has an ester structure, it can replace octyl phthalate Esters and butyl esters are used as plasticizers, and they also contain chlorinated paraffin, which can replace chlorinated paraffin and improve the flame retardancy and electrical insulation of the product. The optimized type I product of this product can replace citric acid plasticizer 50 ~60%; Type II can replace citric acid plasticizers 100%, and the plasticizers need to be refined in the oil foot. The so-called oil foot contains about 50-60% of various long chains Fatty acid, this part of the long-chain fatty acid in the oil residue is extracted to prepare a variety of fine chemical products, so as to turn waste into treasure and improve social and economic benefits. Facing the existing reactor, it can only target a single output material Barrels are used for production, and the reaction kettle needs to be replaced in the face of different sizes of capacity, which is inconvenient to use and has a low effect in terms of refining efficiency. Most of the sealing covers of the existing reaction kettles are fixed from the outside. The plastic will stick to the barrel, it is not easy to separate, and the inside cannot be cleaned, which will easily cause damage to the equipment, reduce the service life, and have a single function
