Ethylicin - Uses and synthesis methods
introduction
pure ethylicin is a colorless oily transparent liquid, heated to 130~140 ℃ for decomposition. Easily soluble in ether, chloroform, ethanol, glacial acetic acid and other organic solvents, the solubility in room temperature water is 1.2%. Industrial products are yellowish oily transparent liquid with garlic odor. Moderate toxicity to warm-blooded animals.
mechanism of action
The mechanism of action of ethylicin is: it interacts with substances containing sulfhydryl groups in the bacteria, thereby inhibiting the normal metabolism of the bacteria.
action
The bactericidal broad spectrum of ethylicin can inhibit Colletotrichum anthracnose, Rhizoctonia solani, Rhizoctonia solani, Rhizoctonia solani, Rhizoctonia solani, Rhizoctonia griseum, Rhizoctonia solani, Rhizoctonia solani, Rhizoctonia solani, Rhizoctonia solani, Rhiz. It can stimulate the growth of plants. The treated seeds have fast emergence and strong seedlings.
Toxicity
acute oral LD50 in rats is 140mg/kg. It has a strong stimulating effect on the skin and mucous membranes, and has no teratogenicity, carcinogenesis, and mutagenicity.
production method
sodium sulfide is dissolved in water, fed with sulfur according to a ratio of 1:1, the reaction temperature is 80~95 ℃, and the disodium disulfide aqueous solution is prepared by keeping the temperature for 1h. Then alkylation of the aqueous solution synthesized in the previous step, passing through the tube chloroethane, reaction temperature 75~90 ℃, pressure 1.18 × 105Pa ~ 1.37 × 105Pa, feeding into disodium disulfide: chloroethane = 1:2, passing through the post-treatment processes of dichloroethane, cooling, standing, water separation, etc., to obtain the corresponding diethyl disulfide. Finally, oxidation treatment is carried out. 300kg of diethyl disulfide and 10kg of ice acid are put into the reaction kettle, the temperature is raised to 50 ℃, 40% nitric acid is added dropwise, the ratio of diethyl disulfide to nitric acid is 1:1.33 (mol ratio), the temperature is controlled to 50~60 ℃, a certain negative pressure (about 9.6 × 104Pa) is maintained, the temperature is kept for 30min after adding nitric.
