Abstract
Dibromomethane is one of a material of several organic componds,it is widely used in pesticide compounding,it's products including CH2(SCN)2、C9H22O4P2S4 and so on.Because of It's high efficiency,low remains and as a kind of broad-spectrum antibacterials,they are generally encouraged to be used by the government.At the same time the dibromomethane is also a kind of fire-retardants,it can evidently reduce the quantity of heat given up when the polymer burning.But the dibromomethane demands a high technical product process and the normal method usually with low outputs,so there are fewer factories to produce the dibromomethane.So it is very important to improve away the normal product process and to develop new product methods.This article notes a new mothod about the production of the dibromomethane.This experiment brings three measures to improve the dibromomethane compounding process.It mainly includes:(1)Using high pure HBr gas to insure to low the influence of the H2 gas.(2)Using acidic katalyst AlCl3 greatly improving the outputs of the materials.(3)Using Na2CO3 solution to wash the dibromomethane,so it farthest lowing the other actions.
