Taw qhia
Methyl furfuryl disulfide (tseem hu ua methyl ethyl sulfide, methyl ethyl sulfide) 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 methylfurfuryldisulfide:
Zoo:
Methylfurfuryl disulfide yog cov xim tsis muaj xim rau cov kua daj daj nrog cov ntxhiab tsw. Nws tsis ruaj khov ntawm chav tsev kub thiab yooj yim decomposes rau sulfur oxides thiab lwm yam sulfur compounds. Nws tuaj yeem yaj hauv cov kuab tshuaj organic, xws li cawv thiab ethers, thiab tsis tshua muaj soluble hauv dej.
Siv:
Methyl furfuryl disulfide muaj ntau yam siv hauv kev lag luam tshuaj. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau dyes thiab pigments, nrog rau cov khoom siv nruab nrab rau qee cov tshuaj tua kab.
Txoj kev:
Methyl furfuryl disulfide tuaj yeem npaj los ntawm oxidation cov tshuaj tiv thaiv ntawm ethylthiosecondary cawv (CH3CH2SH). Cov tshuaj tiv thaiv no feem ntau catalyzed nyob rau hauv lub xub ntiag ntawm ib tug oxidizing neeg sawv cev, xws li hydrogen peroxide los yog persulfate.
Cov ntaub ntawv kev nyab xeeb:
Methylfurfuryl disulfide yog khaus thiab tej zaum yuav ua rau khaus ntawm daim tawv nqaij, qhov muag, thiab ua pa. Cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes thiab tsom iav, yuav tsum hnav thaum siv. Muab nws cov nplaim taws, nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, kom deb ntawm ignition thiab oxidants. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog tiv tauj, nrhiav kev kho mob tam sim ntawd.
