Taw qhia
3-methyl-2-butane mercaptan (tseem hu ua tert-butylmethyl mercaptan) yog organosulfur compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos: cov kua tsis muaj xim
- Soluble: Soluble nyob rau hauv feem ntau cov organic solvents, insoluble nyob rau hauv dej
Siv:
- Nws tuaj yeem siv los tsim cov tshuaj lom neeg lom neeg, thiosilanes, hloov hlau ua haujlwm, thiab lwm yam.
Txoj kev:
- Ib txoj hauv kev npaj 3-methyl-2-butane thiol tau txais los ntawm cov tshuaj tiv thaiv ntawm propyl mercaptan thiab 2-butene, thiab tom qab ntawd cov khoom lag luam tau txais los ntawm lub cev qhuav dej thiab cov tshuaj tiv thaiv methylation.
- Cov txheej txheem npaj yuav tsum tau ua nyob rau hauv kev tiv thaiv ntawm inert gases thiab yuav tsum tau tsim catalysts thiab cov tshuaj tiv thaiv tej yam kev mob kom ua tau siab yields thiab selectivity.
Cov ntaub ntawv kev nyab xeeb:
- 3-Methyl-2-butane mercaptan yog tshuaj lom thiab tej zaum yuav muaj teebmeem kev noj qab haus huv yog tias tau tiv tauj, nqus tau, lossis noj.
- Hnav cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes, tsom iav, thiab hnav ris tsho, thaum siv.
- Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij, qhov muag, khaub ncaws, thiab lwm yam, thiab ua tib zoo saib xyuas kom muaj cua txaus.
- Khaws kaw kom nruj rau hauv qhov chaw txias, qhuav, qhov cua zoo, kom deb ntawm hluav taws thiab oxidants.
