Taw qhia
2-Methyl-1-butanol yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
2-Methyl-1-butanol yog cov kua tsis muaj xim thiab muaj ntxhiab tsw zoo ib yam li cawv. Nws yog soluble hauv dej thiab ntau yam organic solvents.
Siv:
2-Methyl-1-butanol feem ntau yog siv los ua cov kuab tshuaj thiab nruab nrab. Nws yog dav siv nyob rau hauv kev lag luam tshuaj nyob rau hauv alkylation cov tshuaj tiv thaiv, oxidation cov tshuaj tiv thaiv, thiab esterification cov tshuaj tiv thaiv, thiab lwm yam.
Txoj kev:
2-methyl-1-butanol tuaj yeem tau txais los ntawm reacting 2-butanol nrog chloromethane nyob rau hauv alkaline tej yam kev mob. Cov kauj ruam tshwj xeeb ntawm cov tshuaj tiv thaiv yog thawj zaug hnov mob 2-butanol nrog lub hauv paus los tsim cov phenol ntsev sib thooj, thiab tom qab ntawd hnov mob nrog chloromethane kom tshem tawm cov tshuaj chlorine ion thiab tau txais cov khoom lag luam.
Cov Lus Qhia Txog Kev Nyab Xeeb: Nws yog cov kua hluav taws xob uas tuaj yeem tsim cov vapors, yog li nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab qhov kub thiab txias, thiab ib puag ncig zoo-ventilated yuav tsum tau khaws cia. Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab cov mucous daim nyias nyias, thiab yaug tam sim ntawd nrog dej txaus nyob rau hauv thaum muaj xwm txheej sib cuag. Thaum tuav thiab khaws cia, yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam.
