Taw qhia
Isoprene mercaptan yog ib qho organic compound. Nws cov khoom yog raws li nram no:
Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab hydrocarbons.
2. Cov khoom siv tshuaj: Isoprepen mercaptan yog ib qho kev txo qis heev uas tuaj yeem ua rau cov pa oxygen los ua sulfur dioxide. Nws tuaj yeem raug oxidized los ntawm chlorine rau isovaleric acid, los yog oxidized los ntawm oxidants rau sulfuric acid. Isopentol kuj muaj cov cuab yeej ntawm cov tshuaj tiv thaiv ntxiv nrog rau lwm cov tshuaj.
Kev siv ntawm isoprene mercaptan:
1. Cov tshuaj reagents: Isopentanol yog ib qho uas nquag siv los txo tus neeg sawv cev thiab sulfiding tus neeg sawv cev, uas yog dav siv hauv cov organic synthesis thiab analytical chemistry.
2. Tus neeg sawv cev tswm ciab: nws cov ntxhiab tsw muaj zog, isoprel mercaptan feem ntau yog siv los ua cov tshuaj los npog lwm cov ntxhiab tsw phem, xws li ntxiv ib qho nyiaj ntawm isoprene mercaptan rau cov roj ntuj los npog cov ntxhiab tsw.
Muaj ntau ntau txoj hauv kev los npaj isopreamyl mercaptan:
1. Ua los ntawm vinyl cawv: vinyl cawv yog rhuab nrog sulfur los tsim isopentanol.
2. Kev npaj los ntawm 15%-alcohol tov: high-purity isoprem mercaptan tuaj yeem tau los ntawm distilling, concentrating thiab distilling cov kua dej cawv thiab hydrogen sulfide.
Cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug coj mus rau hauv tus account thaum siv isopentanol:
1. Isopentan mercaptan muaj cov ntxhiab tsw ntxhiab thiab yuav tsum tsis txhob sib cuag ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab lub ntsej muag tiv thaiv thaum siv.
2. Isopentol muaj qhov taw tes qis thiab cov nplaim taws, thiab yuav tsum khaws cia kom deb ntawm qhov hluav taws kub thiab kub. Tsis txhob sib cuag nrog cov nplaim taws qhib lossis lwm yam combustibles.
3. Isopentan mercaptan yog ib yam khoom uas tsim kev puas tsuaj rau ib puag ncig thiab muaj cov biodegradability tsis zoo, thiab yuav tsum tsis txhob muab tso rau hauv ib puag ncig ntuj raws li qhov xav tau, thiab yuav tsum tau kho thiab pov tseg raws li cov kev cai cuam tshuam.
