Taw qhia
Allyl mercaptans.
Zoo:
Allyl mercaptan yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li cawv, ethers, thiab cov kuab tshuaj hydrocarbon. Allyl mercaptans oxidize yooj yim, tig daj thaum raug huab cua ntev, thiab txawm tsim disulfides. Nws tuaj yeem koom nrog ntau yam kev cuam tshuam cov organic, xws li nucleophilic ntxiv, esterification cov tshuaj tiv thaiv, thiab lwm yam.
Siv:
Allyl mercaptans feem ntau yog siv rau qee qhov kev cuam tshuam tseem ceeb hauv cov organic synthesis. Nws yog ib qho substrate rau ntau cov enzymes lom thiab tuaj yeem siv rau hauv kev tshawb fawb lom neeg thiab kev kho mob. Allyl mercaptan tseem tuaj yeem siv los ua cov khoom siv raw hauv kev tsim cov diaphragm, iav thiab roj hmab, nrog rau cov khoom muaj nyob hauv cov tshuaj tua kab mob, cov nroj tsuag kev loj hlob regulators thiab surfactants.
Txoj kev:
Feem ntau, allyl mercaptans tuaj yeem tau txais los ntawm reacting allyl halides nrog hydrogen sulfide. Piv txwv li, allyl chloride thiab hydrogen sulfide react nyob rau hauv lub xub ntiag ntawm lub hauv paus los ua ib tug allyl mercaptan.
Cov ntaub ntawv kev nyab xeeb:
Allyl mercaptans yog tshuaj lom, irritating thiab corrosive. Kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab. Cov hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv lossis tuav. Tsis txhob nqus nws cov vapors los yog nkag mus rau ntawm daim tawv nqaij. Kev ua pa zoo yuav tsum tau khaws cia thaum lub sijhawm ua haujlwm kom tsis txhob muaj ntau tshaj qhov txwv tsis pub muaj kev nyab xeeb.
