Kev Siv
Dimethyl Disulfide (DMDS) yog ib yam tshuaj lom neeg uas muaj cov mis C2H6S2. Nws yog ib yam kua tsis muaj xim nrog ib qho tsw ntxhiab tsw phem heev. Nov yog qee yam uas nws siv tseem ceeb:
1. Hauv kev lag luam roj av: DMDS yog siv dav ua cov tshuaj sulfur uas muaj cov tshuaj ntxiv rau hauv kev ua roj av refining. Nws pab txhim kho kev ua haujlwm ntawm cov txheej txheem desulfurization los ntawm kev ua haujlwm ua qhov chaw sulfur. Nws tuaj yeem cuam tshuam nrog cov hlau oxides ntawm qhov chaw ntawm desulfurization catalysts, txhim kho lawv cov haujlwm thiab kev ruaj khov, thiab yog li txhim kho qhov kev tshem tawm ntawm cov tshuaj sulfur uas muaj cov khoom hauv cov khoom roj av.
2. Hauv kev lag luam tshuaj lom neeg: Nws yog ib qho khoom siv tseem ceeb rau kev tsim cov organic sulfur - uas muaj cov tshuaj sib xyaw. Piv txwv li, nws tuaj yeem siv los npaj methanethiol, uas yog siv ntxiv rau hauv kev tsim cov tshuaj tua kab, tshuaj, thiab lwm yam tshuaj zoo. DMDS kuj tseem tuaj yeem siv rau hauv kev tsim cov tshuaj sulfur - uas muaj cov tshuaj heterocyclic, uas muaj cov ntawv thov tseem ceeb hauv kev ua cov organic synthesis.
3. Ua ib qho tshuaj tua kab: Vim nws muaj tshuaj lom rau cov kab thiab cov kab mob me me, DMDS tuaj yeem siv ua ib qho tshuaj tua kab los tswj cov kab tsuag thiab cov pwm hauv cov nplej khaws cia, cov tsev rau khoom, thiab cov tsev cog khoom. Nws tuaj yeem tua ntau yam kab tsuag thiab cov pwm, pab tiv thaiv cov khoom ua liaj ua teb khaws cia thiab tiv thaiv kev kis kab mob.
4. Hauv kev lag luam hluav taws xob: DMDS siv rau hauv kev lag luam semiconductor rau qee cov txheej txheem xws li kev tso cov pa tshuaj lom neeg (CVD). Nws tuaj yeem siv los tso cov yeeb yaj kiab nyias uas muaj sulfur, uas muaj daim ntawv thov hauv kev tsim cov khoom siv hluav taws xob xws li transistors thiab sensors.
5. Hauv kev tshuaj xyuas tshuaj lom neeg: DMDS tuaj yeem siv ua cov tshuaj derivatization hauv kev tshuaj xyuas tshuaj lom neeg. Nws tuaj yeem cuam tshuam nrog qee pawg ua haujlwm hauv cov organic sib xyaw ua ke los tsim cov derivatives nrog cov khoom chromatographic lossis spectroscopic zoo dua, pab txhawb kev sib cais thiab kev tshawb pom ntawm cov sib xyaw no. Piv txwv li, nws tuaj yeem siv rau hauv kev tshuaj xyuas cov roj fatty acids thiab lwm cov organic sib xyaw los ntawm roj chromatography - pawg spectrometry (GC - MS).
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
