Qee qhov kev paub txog Dimethyl Disulfide (CAS: 624-92-0)

1.Cov khoom siv tshuaj lom neeg:

Cov kua daj daj ntshiab. Muaj ntxhiab tsw phem. Nws tsis yaj hauv dej thiab tuaj yeem sib xyaw nrog ethanol, ether, thiab acetic acid.

2. Lub Hom Phiaj:

Siv 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 O2, O-dimethyl phosphoryl sulfide chloride hauv Chemicalbook alkaline nruab nrab kom tau txais Fenthion. Qhov no yog cov tshuaj tua kab organic phosphorus zoo thiab tsis muaj tshuaj lom nrog kev tswj hwm zoo heev rau cov kab laum mov, cov kab mob plawv taum pauv, thiab cov kab laug sab gadfly. Nws kuj tseem siv tau ua tshuaj kho tsiaj kom tshem tawm cov kab laug sab cowfly thiab cov ntshauv ntawm phab ntsa nyuj.

3. Txoj kev tsim khoom:

Dimethyl disulfide yog synthesized los ntawm Dimethyl sulfate txoj kev hauv kev lag luam.

Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4 Muab cov khoom khov kho Sodium sulfide thiab dej rau hauv lub lauj kaub tshuaj, ua kom sov, tswj qhov kub ntawm 50 ~ 60 ℃ kom yaj Sodium sulfide hauv phau ntawv Chemicalbook, tom qab ntawd ntxiv equimolar sulfur ua pawg, ua kom sov rau 1 teev, txias rau 45 ℃, pib tso Dimethyl sulfate, ua kom qhov kub ntawm 40 ~ 45 ℃, thiab ua kom sov rau 1 teev tom qab ntxiv, cov khoom Dimethyl disulfide tuaj yeem raug ncu tawm. Tsis tas li ntawd, Dimethyl disulfide kuj tseem tuaj yeem tsim los ntawm methyl mercaptan txoj kev.

4. Cov yam ntxwv ntawm kev khaws cia thiab kev thauj mus los:

Kev ua pa thiab ziab qhov kub qis ntawm lub tsev rau khoom; Khaws cia cais ntawm cov tshuaj oxidants thiab cov kua qaub
