 Diethyldisulfide (CAS NO.110-81-6) is the preparation method is the first release within the reactor sodium sulfide solution, according to sodium sulfide: sulfur = 1:1 (molar ratio) is expected to vote put sulfur powder, jacket temperature, in the stirring, when the temperature reached 80 ~ 95 °C when the Serve warm 1h disulfide disodium salt (Na2S2) solution, and then pumped into the alkylation reactor in disulfide disodium salt solution, start stirring until the reaction vessel to a vacuum (2 ~ 3.3) × 104Pa off valves start the chlorine into the ethane, the reaction temperature was controlled at 75 ~ 90 °C, pressure control (1.17 ~ 1.18) × 105Pa, feed ratio (mole ratio) disulfide disodium salt: ethyl = 1:2, Tung finished chloroethane, the will be expected to cool to below 50 °C will be expected to put it aside for the oil pumped to the water separator layer, the upper reservoir shall be finished.

Reported in EPA TSCA Inventory.
