1.Cov khoom siv tshuaj:
Lub teeb daj pob tshab kua.Muaj tus ntxhiab tsw phem.Nws yog insoluble hauv dej thiab tuaj yeem sib xyaw nrog ethanol, ether, thiab acetic acid.
2. Lub hom phiaj:
Siv los ua tus neeg sawv cev passivating rau cov kuab tshuaj, catalysts, tshuaj tua kab intermediates, coking inhibitors, thiab lwm yam. Dimethyl disulfide reacts nrog cresol los tsim 2-methyl-4-hydroxy anisulfide, thiab tom qab ntawd condenses nrog O, O-dimethyl phosphoryl sulfide chloride hauv Chemicalbook alkaline. nruab nrab kom tau Fenthion.Qhov no yog cov tshuaj tua kab mob uas muaj txiaj ntsig zoo thiab tsis tshua muaj toxicity organic phosphorus insecticide nrog kev tswj zoo heev ntawm cov nplej borers, soybean heartworms, thiab gadfly larvae.Nws tseem tuaj yeem siv los ua cov tshuaj kho tsiaj txhawm rau tshem tawm cov cowfly maggots thiab nyuj phab ntsa ntshauv.
3.Production method:
① Nws tau txais los ntawm cov tshuaj tiv thaiv ntawm Dimethyl sulfate thiab Sodium sulfide.Ntxiv cov hmoov sulfur rau hauv Sodium sulfide tov nyob rau hauv nplawm, nce qhov kub ntawm 80-90 ℃, react rau 1h, thiab txo qhov kub ntawm cov tshuaj Chemicalbook kom txog 30 ℃;Dimethyl sulfate poob rau hauv cov tshuaj tiv thaiv kettle, cov tshuaj tiv thaiv txuas ntxiv rau 2h, thiab tom qab ntawd distilled, sawv rau txheej.Tom qab cais cov khib nyiab alkali cawv, cov khoom tiav yog tau los ntawm distillation.
② Dimethyl disulfide yog tsim los ntawm Dimethyl sulfate hauv kev lag luam.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Muab cov khoom Sodium sulfide thiab dej tso rau hauv cov tshuaj tiv thaiv kettle, ua kom sov, tswj qhov kub ntawm 50 ~ 60 ℃ kom yaj cov sulfurized Chemicalbook sodium, ces ntxiv equimolar sulfur nyob rau hauv batch, cia nws sov rau 1h, txias rau 45 ℃, pib. xau Dimethyl sulfate, khaws cov tshuaj tiv thaiv kub ntawm 40 ~ 45 ℃, ua kom sov li 1h tom qab ntxiv, thiab tom qab ntawd evaporate cov khoom Dimethyl disulfide.Tsis tas li ntawd, Dimethyl disulfide tuaj yeem ua ke los ntawm txoj kev methyl mercaptan.
③Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm iodomethyl magnesium thiab Disulfur dichloride.Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm sodium disulfide nrog sodium methylsulfate.Methyl Sodium thiosulfate yog npaj los ntawm reacting Bromomethane nrog Sodium thiosulfate, thiab ces cua sov.
4. Kev khaws cia thiab kev thauj mus los yam ntxwv:
Qhov cua thiab cua kub kom qhuav ntawm lub warehouse;Khaws cais ntawm oxidants thiab acids
5.Tus neeg tua hluav taws tua hluav taws
Cov hmoov qhuav, xuab zeb qhuav, carbon dioxide, ua npuas ncauj, 1211 extinguishing agent
Tam sim no, Jinan ZhongAn Kev Lag Luam Co., Ltd yog tsis tu ncua muab DMDS rau cov lag luam loj.Thaum lub Cuaj Hlis xyoo no, Jinan ZhongAn Kev Lag Luam Co., Ltd yuav nthuav peb cov kab ntau lawm kom tau raws li qhov xav tau ntawm cov neeg siv khoom ntau.Peb zoo siab txais tos cov neeg siv khoom los ntawm thoob plaws lub ntiaj teb los sab laj peb.Peb lub tuam txhab kuj tau txais ISO9001 ntawv pov thawj.Thov so assured ntawm cov khoom zoo.
