Ethylicin Use and Manufacturing

Methods of Manufacturing

Sodium sulfide is dissolved in water and fed with sulfur in a ratio of 1:1. The reaction temperature is 80-95° C. and the temperature is kept for 1 hour to prepare a disodium disulfide aqueous solution. Then alkylate the aqueous solution synthesized in the previous step, pipe chloroethane, the reaction temperature is 75～90℃, the pressure is 1.18×105Pa～1.37×105Pa, the feed is disodium disulfide: chloroethane=1:2, pass through Dichloroethane undergoes post-treatment processes such as cooling, standing, and water separation to obtain the corresponding diethyl disulfide. Finally, oxidation treatment is carried out, 300kg of diethyl disulfide and 10kg of glacial acid are put into the reactor, the temperature is raised to 50 ℃, 40% nitric acid is added dropwise, and the ratio of diethyl disulfide to nitric acid is 1:1.33 ( mol ratio), control the temperature to 50～60℃, maintain a certain negative pressure (about 9.6×104Pa), keep the temperature for 30 minutes after adding nitric acid, cool, and discharge the material to separate water to prepare the antibacterial agent 402.

Uses

Used to control cotton blight, apple leaf spot, etc.
