Difurfuryl disulfide (CAS # 4437-20-1)

Taw qhia

Difurfuryl disulfide (tseem hu ua difurfurylsulfur disulfide) yog cov organic sulfur compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

Zoo:

- Cov kua dej tsis muaj xim rau yellowish nyob rau hauv tsos.

- Muaj ib tug pungent tsw.

- Soluble hauv cov kuab tshuaj organic xws li cawv, ethers thiab hydrocarbons ntawm chav tsev kub.

Siv:

- Difurfuryl disulfide yog dav siv los ua ib qho catalyst rau foaming agents, adhesives, thiab vulcanizing agents.

- Nws tuaj yeem siv rau vulcanization ntawm polyester cob, uas yog siv los ua kom cov cua sov ua haujlwm thiab lub zog ntawm polyester resin.

- Nws kuj tuaj yeem siv rau hauv kev lag luam roj hmab rau vulcanize roj hmab kom nws lub zog thiab kub ua hauj.

Txoj kev:

- Difurfuryl disulfide feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm ethanol thiab sulfur.

- Cov khoom tuaj yeem tau txais los ntawm cua sov ethanol thiab sulfur nyob rau hauv muaj cov roj inert thiab tom qab ntawd distilling nws.

Cov ntaub ntawv kev nyab xeeb:

- Difurfuryl disulfide muaj ntxhiab tsw thiab yuav ua rau khaus thaum sib cuag nrog daim tawv nqaij, yog li kev sib cuag ntev yuav tsum zam.

- Thaum siv lossis khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj oxidants, acids, thiab alkalis kom tsis txhob muaj kev phom sij txaus ntshai.

- Nws muaj toxicity tsawg, tab sis tseem yuav tsum tau saib xyuas kom tsis txhob nqus nws cov vapors, tsis txhob noj thiab sib cuag nrog lub qhov muag thiab cov mucous daim nyias nyias.

- Ua raws li kev soj ntsuam zoo thiab hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav thaum tuav difurfuryl disulfide.

- Thaum pov tseg cov khoom pov tseg, nws yuav tsum muab pov tseg raws li cov cai hauv cheeb tsam ib puag ncig thiab tsis txhob muab pov tseg rau hauv ib puag ncig.
