Diethyl disulfide (110-81-6) is colorless oil, b.p. 151-153 ℃, n20D 1.5060, relative density 0.993, insoluble in water, soluble in organic solvents. Diethyl disulfide use 1, is an intermediate of the bactericide ethylallicin. 2, as an organic synthesis intermediate production method diethyl disulfide (110-81-6) preparation method is to put human sodium sulfide solution in the reactor first, according to sodium sulfide: sulfur =1∶1(molar ratio) feed into sulfur powder, the clip is heated up, under stirring, when the temperature reaches 80 ~ 95℃, holding the heat for 1 hour to obtain sodium disulfide (Na2S2) solution. Then, the disodium disulfide solution was pumped into the alkane reactor and started to stir. When the reactor was vacuumed to (2 ~ 3.3)×104Pa, the vacuum valve was closed and the chloroethane was introduced. The reaction temperature was controlled at 75 ~ 90℃, the pressure was controlled at (1.17 ~ 1.18)×105Pa, and the feeding ratio (molar ratio) was sodium disulfide ∶ chloroethane =1∶2. After passing through the chloroethane, the material is cooled to below 50 ° C, and the oil is pumped to the water separator for static stratification, and the upper oil layer is the finished product. 2C2H5Cl+Na2S+S→C2H2 -- S -- S -- C2H5+2NaCl Upstream and downstream Product information Upstream raw materials sulfur water distributor Disodium valve Molybdenum disulfide downstream product zinc diethyl dithiocarbamate ethyl alliin quiforn.
