| titleOfInvention | Preparation process, preparation facilities and the preparation method of methyl phosphinate |
| abstract | The invention discloses the preparation process and corresponding preparation facilities of a kind of more efficient, more low pollution and safer methyl phosphinate and preparation methods, belong to the production technical field of methyl phosphinate.By under the condition of negative pressure of ﹣ 0.095MPa~﹣ 0.001MPa, and under conditions of reaction temperature is 35 DEG C~90 DEG C, methyl phosphinate is made in the reaction for carrying out methyl dichloro phosphorus and alcohol roh, one side byproduct of reaction chlorohydrocarbon and alcohol can instant vaporization heat absorptions, the heat that reaction is released quickly is taken away, carry out reaction can smoothly at a lower temperature；On the other hand hydrogen chloride, chlorohydrocarbon and alcohol etc. quickly can be removed into reaction system, avoids the generation of side reaction caused by hydrogen chloride, reduce the generation of noxious material, improves the safety of production.In addition, can be without adding acid binding agent in the present invention, and can be continuously produced to improve production efficiency, reduce the pollution to environment, save the cost；It is very suitable to large-scale industrial production. |
