Kev npaj
Bromododecane, thiourhanol yog rhuab rau reflux cov tshuaj tiv thaiv, ces sodium hydroxide tov yog ntxiv thiab rhuab. Tom qab cov tshuaj tiv thaiv tau ua tiav, txias thiab qub txheej txheej, cov txheej roj, txheej roj yog tus neeg tawg. Cov khoom crude yog ntxuav nrog dej, qhuav, distilled thiab distilled nyob rau hauv siab txo, uas yog N-Dodecanetiol.

Kev xyuas xim
Lub vapor lossis merist yog khaus rau lub qhov ntswg thiab caj pas. Lub vapor lossis merist ntawm cov khoom no yog khaus rau lub qhov ntswg thiab caj pas. Kev inhalation siab ua rau mob taub hau, xeev siab, ntuav thiab txawm tias coma. Kev puas tsuaj rau ib puag ncig, kev saib xyuas yuav tsum tau them rau cov pa phem ntawm dej ib puag ncig thiab cov aquefers. Khaws rau hauv qhov txias, lub tsev muag khoom uas muaj qhov cua. Tseg kom deb ntawm hluav taws thiab tshav kub. Tiv thaiv los ntawm kev tshav ntuj ncaj qha. Kaw cov thawv ntim. Yuav tsum tau muab khaws cia cais los ntawm oxidizers, acids thiab tshuaj tau.
Tshuaj Tshuaj Muaj Zog

Kev siv
Dodecanethiol tuaj yeem siv los ua tus txheeb ze cov roj av tswj ntawm polymer tebchaw. Siv ua cov kev tswj hwm polymerization rau cov roj hmab hluavtaws, hluavtaws fiber ntau, hluavtaws cov khoom siv hluavtaws; Kuj siv nyob rau hauv kev tsim cov khoom siv ntawm PVC Stabilizers, tshuaj, fungicides ntawm cov roj hmab hluav taws xob, hluavtaws fiber ntau, hluavtaws resin; Kuj siv nyob rau hauv kev tsim cov khoom siv ntawm PVC stabilizers, tshuaj, tshuaj, fungicides, excontaminants, thiab lwm yam; siv raws li tus txheeb ze cov roj av tswj ntawm polymer sib txuas; siv nyob rau hauv roj hmab, plastics thiab kws tshuaj ntsuam kev lag luam.
Txuj Ci Ntau Lawm
Hauv chav kuaj mob tuaj yeem ua ke raws li cov qauv hauv qab no. Qhov sib xyaw ntawm 125g ntawm bromododecane, 38g ntawm thiourea thiab 250mL ntawm 95% ethanol yog rhuab thiab refluxed rau 3H. 30g ntawm sodium hydroxide thiab 300ml ntawm dej ntxiv rau kev daws, thiab tom qab ntawd qhov sib tov yog refluxed rau lwm 2H. Cov txheej roj txheej yog cov crude mercaptan, thiab txheej aqueous yog acid acc acc muaj acidulified thiab muab rho tawm nrog benzene. Cov Extract tau sib xyaw ua ke nrog cov crude mercaptan, ntxuav nrog dej benzene thiab tom qab ntawd {8}} degree (5.19kpa) feem kev tawm tsam yog cov khoom lag luam. Txog {80-84 g yog tau txais, cov txiaj ntsig yog li 80%.
