Intshayelelo
I-Dimethyldichlorosilane yi-organosilicon compound.
Umgangatho:
1. Imbonakalo: ulwelo olungenambala okanye olukhanyayo olutyheli.
2. Ukunyibilika: ukunyibilika kwizinyibilikisi eziphilayo, ezifana alcohols kunye esters.
3. Ukuzinza: Izinzile kwiqondo lokushisa, kodwa inokubola xa ishushu.
4. Ukuphinda kusebenze: Inokusabela ngamanzi ukwenza i-silica alcohol kunye ne-hydrochloric acid. Inokuthi ithathelwe indawo nge-ethers kunye ne-amines.
Sebenzisa:
1. Njengomqalisi: Kwi-organic synthesis, i-dimethyldichlorosilane ingasetyenziselwa umqalisi ukuqalisa ukuphendulwa kwe-polymerization ethile, njenge-synthesis ye-silicon-based polymers.
2. Njenge-agent edibanisayo: I-Dimethyl dichlorosilane inokusabela kunye nezinye iikhompawundi ukwenza isakhiwo esinqamlekileyo, esisetyenziselwa ukulungiselela izinto ze-elastomer ezifana ne-rubber silicone.
3. Njenge-ejenti yokunyanga: Kwiingubo kunye ne-adhesives, i-dimethyldichlorosilane inokusabela kunye neepolymers eziqukethe i-hydrogen esebenzayo ukunyanga kunye nokwandisa ukuchasana kwemozulu yezinto.
4. Isetyenziswe kwi-organic synthesis reactions: I-Dimethyldichlorosilane ingasetyenziselwa ukudibanisa ezinye iinqununu ze-organosilicon kwi-organic synthesis.
Indlela:
1. Ifunyenwe kwi-reaction ye-dichloromethane kunye ne-dimethylchlorosilanol.
2. Ifumaneka kwi-reaction ye-methyl chloride silane kunye ne-methyl magnesium chloride.
Ulwazi ngoKhuseleko:
1. Iyacaphukisa kwaye iyatshisa, yihlambulule ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango xa idibana nolusu kunye namehlo.
2. Kuphephe ukuphefumla umphunga wayo xa uyisebenzisa ukuqinisekisa ukungena komoya kakuhle.
3. Zigcine kude nemithombo yomlilo kunye nee-oxidants, gcina isikhongozeli singangeni moya, kwaye usigcine kwindawo epholileyo neyomileyo.
4. Musa ukudibanisa ne-acids, i-alcohol kunye ne-ammonia ukuphepha ukuphendula okuyingozi.
5. Xa ulahla inkunkuma, thobela imigaqo efanelekileyo kunye nezikhokelo zokusebenza zokhuseleko.
