Cov Khoom Noj Khoom Haus & Cov Tshuaj Ntsuab Diethyl Disulfide/Ethyl Disulfide [110-81-6] FEMA 4093

Lub Npe Tshuaj: Diethyl Disulfide
Cov Lus Txhais: Ethyl Disulfide; ethane-1,1-bis (thiolate); Diethyl disulphide
Qhov hnyav molecular: C2H4S2
Tsos: Pob tshab rau cov kua daj
Kev Ruaj Ntseg: 1. Tsis txhob lwj thaum kub thiab siab, tsis txhob sib cuag nrog cov oxidants.
2. Muaj nyob rau hauv cov pa luam yeeb loj.

Diethyl disulfide (110-81-6) yog roj tsis muaj xim, bp 151-153 ℃, n20D 1.5060, qhov ceev ntawm qhov sib piv 0.993, tsis yaj hauv dej, yaj hauv cov kuab tshuaj organic. Diethyl disulfide siv 1, yog ib qho nruab nrab ntawm cov kab mob ethylallicin. 2, ua ib txoj kev tsim khoom nruab nrab ntawm cov organic synthesis diethyl disulfide (110-81-6) txoj kev npaj yog muab cov kua sodium sulfide tib neeg tso rau hauv lub reactor ua ntej, raws li sodium sulfide: sulfur = 1∶1 (molar ratio) pub rau hauv cov hmoov sulfur, lub clip raug cua sov, nyob rau hauv kev sib xyaw, thaum qhov kub txog 80 ~ 95 ℃, tuav qhov kub rau 1 teev kom tau txais cov kua sodium disulfide (Na2S2). Tom qab ntawd, cov kua disodium disulfide tau pumped rau hauv lub reactor alkane thiab pib do. Thaum lub reactor raug nqus mus rau (2 ~ 3.3) × 104Pa, lub qhov nqus tsev raug kaw thiab chloroethane tau qhia. Qhov kub ntawm cov tshuaj tiv thaiv tau tswj hwm ntawm 75 ~ 90 ℃, qhov siab tau tswj hwm ntawm (1.17 ~ 1.18) × 105Pa, thiab qhov piv ntawm kev pub mis (molar ratio) yog sodium disulfide ∶ chloroethane = 1∶2. Tom qab dhau los ntawm chloroethane, cov khoom siv tau txias rau hauv qab 50 ° C, thiab cov roj tau pumped rau lub tshuab cais dej rau kev faib tawm zoo li qub, thiab cov roj txheej sab saud yog cov khoom tiav. 2C2H5Cl + Na2S + S → C2H2 -- S -- S -- C2H5 + 2NaCl Cov ntaub ntawv khoom ntws mus rau sab saud thiab sab hauv qab Cov ntaub ntawv khoom ntws mus rau sab saud cov khoom siv raw sulfur dej faib Disodium valve Molybdenum disulfide cov khoom ntws mus rau sab hauv qab zinc diethyl dithiocarbamate ethyl alliin quiforn.
