Taw qhia
Diethyl disulfide (tseem hu ua diethyl nitrogen disulfide) yog ib qho organosulfur compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diethyldisulfide:
Zoo:
- Cov tsos mob: tsis muaj xim rau cov kua daj daj daj
- Solubility: Soluble nyob rau hauv organic solvents xws li cawv, ethers, ethers thiab ketones, insoluble nyob rau hauv dej.
Siv:
- Diethyldisulfide feem ntau yog siv los ua crosslinker, vulcanizing tus neeg saib xyuas thiab kev hloov pauv hloov pauv.
- Nws reacts nrog polymers uas muaj cov amino thiab hydroxyl pawg los tsim ib qho kev sib txuas sib txuas los txhim kho lub zog thiab hnav tsis kam ntawm polymer.
- Nws kuj tuaj yeem siv los ua cov khoom siv raw rau catalysts, achromatics, antioxidants, antimicrobial agents, thiab lwm yam.
Txoj kev:
- Diethyl disulfide feem ntau yog npaj los ntawm ethanol cov tshuaj tiv thaiv los tsim thioether. Nyob rau hauv cov kev mob tshwm sim, nyob rau hauv lub xub ntiag ntawm ethoxyethyl sodium catalysis, sulfur thiab ethylene raug txo los ntawm lithium aluminate los ua ethylthiophenol, thiab tom qab ntawd etherification cov tshuaj tiv thaiv nrog ethanol tab tom ua etherification cov tshuaj tiv thaiv kom tau txais cov khoom ntawm diethyldisulfide.
Cov ntaub ntawv kev nyab xeeb:
- Diethyl disulfide yog cov kua ua kua, yuav tsum tau saib xyuas kom tsis txhob muaj hluav taws kub thiab kub.
- Khaws ib puag ncig zoo-ventilated thaum siv thiab khaws cia.
- Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes tshuaj, tsom iav, thiab khaub ncaws tiv thaiv thaum ua haujlwm.
