Taw qhia
Methyl Thiobutyrate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm methyl thiobutyrate:
1. Xwm:
Methyl thiobutyrate yog cov kua tsis muaj xim nrog cov ntxhiab tsw tsw qab. Nws tuaj yeem soluble hauv cawv, ethers, hydrocarbons, thiab qee cov kuab tshuaj organic.
2. Kev siv:
Methyl thiobutyrate feem ntau yog siv los ua cov tshuaj tua kab thiab tshuaj tua kab, tshwj xeeb tshaj yog nyob rau hauv kev tswj cov kab tsuag xws li ntsaum, yoov tshaj cum thiab qej maggots. Nws kuj tseem siv tau los ua ib qho nruab nrab hauv cov organic synthesis rau cov synthesis ntawm lwm cov tebchaw.
3. Txoj kev:
Kev npaj ntawm methyl thiobutyrate feem ntau yog tau los ntawm cov tshuaj tiv thaiv ntawm sodium thiosulfate nrog bromobutane. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
Sodium thiosulfate yog reacted nrog bromobutane nyob rau hauv alkaline tej yam kev mob los tsim sodium thiobutyl sulfate. Tom qab ntawd, nyob rau hauv lub xub ntiag ntawm methanol, cov tshuaj tiv thaiv reflux yog rhuab rau esterify sodium thiobutyl sulfate nrog methanol los tsim methyl thiobutyrate.
4. Cov ntaub ntawv kev nyab xeeb:
Methyl thiobutyrate muaj toxicity siab. Nws tuaj yeem tsim kev puas tsuaj rau tib neeg lub cev thiab ib puag ncig. Kev raug methyl thiobutyrate tuaj yeem ua rau tawv nqaij khaus, khaus qhov muag, thiab ua pa ua pa. Nyob rau hauv high concentrations, nws kuj yog flammable thiab explosive. Thaum siv methyl thiobutyrate, kev tiv thaiv tus kheej yuav tsum tau ua kom muaj zog, tiv thaiv kev sib cuag nrog cov tawv nqaij thiab qhov muag, thiab siv nyob rau hauv qhov chaw muaj cua zoo yuav tsum xyuas kom meej. Tsis tas li ntawd, cov txheej txheem tswj xyuas kev nyab xeeb thiab cov kev cai yuav tsum tau ua raws li kev tuav thiab khaws cia ntawm qhov sib xyaw. Yog tias muaj cov tsos mob lom tshwm sim, nrhiav kev kho mob tam sim ntawd.
