Kev siv
Dimethyl Distride (DMDs) yog ib qho tshuaj lom neeg sib xyaw nrog cov mis C2h6s2. Nws yog cov kua tsis muaj kob uas muaj cov muaj zog, tsis kaj siab. Nov yog qee qhov ntawm nws lub ntsiab siv:
1. Hauv kev lag luam roj av: DMDs tau siv dav ua ib tus neeg leej faj - muaj kev ntxiv hauv roj av ntxiv. Nws pab txhim kho kev ua haujlwm ntawm cov txheej txheem desulfurization los ntawm kev ua yeeb yam raws li cov neeg leej faj. Nws tuaj yeem cuam tshuam nrog hlau oxides nyob rau saum npoo ntawm desulfurization catalysts, txhim kho lawv cov haujlwm thiab yog li txhim kho qhov kev tshem tawm ntawm leej faj - muaj cov tebchaw hauv cov roj av.
2. Hauv kev lag luam tshuaj: nws yog ib qho khoom siv tseem ceeb rau cov synthesis ntawm ntau yam organic ulfur - muaj cov tebchaw. Piv txwv li, nws tuaj yeem siv los npaj cov metanethiol, uas yog txuas ntxiv nyob rau hauv kev tsim cov tshuaj tua kab, tshuaj, thiab lwm yam tshuaj zoo. DMDs kuj tseem siv tau rau hauv synthesis ntawm ib co leej faj - muaj heterocyclic tebchaw, uas muaj cov ntawv thov tseem ceeb hauv thaj chaw muaj synthesis.
3. Raws li ib tug fumigant: vim nws cov kuab lom rau cov kab thiab cov kab mob me, fungi hauv khw muag zaub thiab fungi hauv khw muag khoom noj, chaw khaws khoom, thiab tsev ntsuab. Nws tuaj yeem tua ntau cov kab tsuag thiab fungi, pab tiv thaiv tiv thaiv cov khoom ua liaj ua teb khaws thiab tiv thaiv kab mob.
4. Nyob rau hauv teb ntawm electronics: dMDs yog siv nyob rau hauv kev lag luam semiconductor rau qee yam tshuaj vapor deposition (CVD). Nws tuaj yeem siv tau los tso nyiaj ntawm leej faj - muaj cov yeeb yaj kiab nyias nyias, uas muaj cov ntawv thov hauv cov khoom siv hluav taws xob xws li cov transistors thiab sensors.
5. Hauv kev ntsuas tshuaj chemistry: dMDs tuaj yeem siv ua derivatization reagent hauv kev ntsuas anchister. Nws tuaj yeem cuam tshuam nrog qee pab pawg ua haujlwm hauv cov organic sib txuas los ua cov khoom sib txuas nrog cov roj ntsha lossis hluav taws xob zoo dua, txhawb kev sib cais thiab nrhiav kom pom ntawm cov tebchaw no. Piv txwv li, nws tuaj yeem siv rau hauv kev tsom xam ntawm fatty acids thiab lwm cov organic cov roj av los ntawm cov roj chromatography - huab hwm coj loj (GC - MS).
Khaws thiab Cia
Txee lub neej: 24 lub hlis txij hnub ua lag luam hauv cov khoom ntim tsis tau ntim rau hauv qhov chaw txias txias tawm ntawm lub hnub ncaj qha, dej.
Qhov chaw ua kom lub tsev rau khoom, tsis muaj kub kom qhuav ziab, sib cais los ntawm oxidants, acids.
