Taw qhia
Dimethyldichlorosilane yog ib qho organosilicon compound.
Zoo:
1. Cov tsos mob: tsis muaj xim lossis lub teeb daj ua kua.
2. Solubility: soluble nyob rau hauv organic solvents, xws li cawv thiab esters.
3. Stability: Nws ruaj khov ntawm chav tsev kub, tab sis tuaj yeem decompose thaum rhuab.
4. Reactivity: Nws tuaj yeem cuam tshuam nrog dej los tsim silica cawv thiab hydrochloric acid. Nws tuaj yeem hloov tau nrog ethers thiab amines.
Siv:
1. Raws li tus neeg pib: Hauv kev sib xyaw ua ke ntawm cov organic, dimethyldichlorosilane tuaj yeem siv los ua tus thawj coj los pib qee yam kev cuam tshuam polymerization, xws li kev sib xyaw ntawm silicon-based polymers.
2. Raws li tus neeg sawv cev sib txuas: Dimethyl dichlorosilane tuaj yeem cuam tshuam nrog lwm cov tebchaw los tsim cov qauv sib txuas, uas yog siv los npaj cov ntaub ntawv elastomer xws li silicone roj hmab.
3. Raws li tus neeg sawv cev kho: Hauv cov txheej txheej thiab cov nplaum, dimethyldichlorosilane tuaj yeem hnov mob nrog cov polymers uas muaj cov tshuaj hydrogen los kho thiab ua kom huab cua tsis kam ntawm cov ntaub ntawv.
4. Siv nyob rau hauv cov organic synthesis cov tshuaj tiv thaiv: Dimethyldichlorosilane tuaj yeem siv los ua ke rau lwm cov organosilicon tebchaw hauv cov organic synthesis.
Txoj kev:
1. Nws yog tau los ntawm cov tshuaj tiv thaiv ntawm dichloromethane thiab dimethylchlorosilanol.
2. Nws yog tau los ntawm cov tshuaj tiv thaiv ntawm methyl chloride silane thiab methyl magnesium chloride.
Cov ntaub ntawv kev nyab xeeb:
1. Nws yog khaus thiab corrosive, yaug tam sim ntawd nrog dej txaus thiab nrhiav kev pab kho mob thaum nws los rau ntawm daim tawv nqaij thiab qhov muag.
2. Tsis txhob nqus nws cov vapors thaum siv los ua kom muaj cua zoo.
3. Khaws kom deb ntawm qhov hluav taws kub thiab cov oxidants, khaws lub thawv airtight, thiab khaws cia rau hauv qhov chaw txias, qhuav.
4. Tsis txhob sib xyaw nrog cov kua qaub, cawv thiab ammonia kom tsis txhob muaj kev phom sij txaus ntshai.
5. Thaum pov tseg cov khoom pov tseg, ua raws li cov kev cai cuam tshuam thiab cov lus qhia kev nyab xeeb.
