Hexamethyldisilazane (HMDZ)

Tom ntej: Hexamethyldisilazane (HMDZ, CAS 999-97-3)

Siv Silylation Reagent rau Nto Dehydroxylation & Moisture -Sensitive Systems

Hexamethyldisilazane (HMDZ, CAS 999-}97-3) yog ib qho nitrogen-muaj organosilicon compound dav siv los ua ib qhoSilylation thiab dehydroxylation reagenthauv kev kho deg thiab ya raws - cov txheej txheem tshuaj rhiab heev.
Tsis zoo li reactive siloxane intermediates siv hauv polymer synthesis, HMDZ feem ntau yog xaiv rau nws lub peev xwm.tshuaj hloov kho hydroxyl pawgnyob rau ntawm qhov chaw inorganic lossis ua haujlwm molecules.

HMDZ feem ntau yog siv nyob rau hauv qhov chaw passivation, muab tub lim, kev npaj catalyst, thiab tshwj xeeb tshuaj synthesis qhov twgnoo noo tswj thiab nto stabilitytseem ceeb.

Cov pab pawg Hydroxyl tam sim no nyob rau ntawm qhov chaw tsis muaj kab mob lossis cov khoom siv nquag tuaj yeem cuam tshuam rau kev ruaj ntseg, kev ua haujlwm, thiab kev sib raug zoo hauv cov txheej txheem qis.
HMDZ raug xaiv vim nws ua haujlwm zoo nrog -OH pawg, hloov lawv nrogtrimethylsilyl (–Si(CH₃)₃) cov, yog li txo qhov polarity thiab noo noo rhiab heev.

Cov laj thawj tseem ceeb rau kev xaiv HMDZ suav nrog:

• Siv taudehydroxylationntawm silica, hlau oxides, thiab muab tub lim
• Txhim khohydrophobicity thiab cia stabilityntawm cov ntaub ntawv kho mob
• Txo cov kev xav sab nraud uas tshwm sim los ntawm qhov chaw -OH pawg

Piv nrog chlorosilanes, HMDZ muaj cov tshuaj tiv thaiv me me thiab zam kev xeb los ntawm - cov khoom, ua rau nws tsim nyog rau cov tshuab rhiab heev.

Cov txiaj ntsig raug muab rau kev siv thev naus laus zis thiab tsis sawv cev tshwj xeeb txwv.

HMDZ reacts nrog hydroxyl pab pawg los ntawm ib tug silylation mechanism, tsim ruaj khov trimethylsilyl-capped nto thaum tso ammonia raws li ib tug los ntawm - khoom.
Cov tshuaj tiv thaiv no txo ​​qis lub zog ntawm qhov chaw thiab txo qhov nqus dej noo tsawg, ua rau txhim kho kev sib raug zoo hauv hydrophobic lossis noo noo- ib puag ncig rhiab heev.

Qhov tsis muaj halogen-muaj los ntawm- cov khoom ua rau HMDZ tshwj xeeb tshaj yog rau cov ntawv thov uaskhoom purity thiab corrosion tswjtseem ceeb.

HMDZ feem ntau yog xaiv thaum:

• Surface -OH pawg yuav tsum yogchemically neutralized
• Moisture rhiab heev cuam tshuam rau kev ua haujlwm lossis kev cia khoom
• Cov mob me me silylation yog nyiam dua li cov tshuaj tiv thaiv hnyav

Rau cov ntawv thov xav taureactive siloxane intermediates, HMDZ tsis yog siv los ua polymer-lub tsev thaiv tab sis ua ibnto chemistry modifier.

HMDZ tau muab rau hauv150 kg steel nruasrau industrial siv.
Khaws cov khoom hauvsealed thawj ntimhauv atxias, qhuav, thiab zoo - qhov cua, tiv thaiv los ntawm ya raws thiab cua sov.
Raws li kev pom zoo khaws cia, HMDZ tswj kev ruaj ntseg raumus txog 12 lub hlis.

Cov ntaub ntawv cov ntaub ntawv (TDS), cov ntaub ntawv kev nyab xeeb (SDS), thiab cov ntawv thov kev txhawb nqa muaj nyob rau thaum thov.
