Aluminiumisopropoxide CAS: 555-31-7

Isopropoxide-ka aluminiumku wuxuu door muhiim ah ka ciyaaraa dhinacyo kala duwan sida sayniska agabka, kiimikada dabiiciga ah, iyo katalisnimada, taasoo gacan ka geysanaysa horumarinta agabka horumarsan, kiimikooyinka wanaagsan, iyo hababka warshadaha. Sayniska agabka, Isopropoxide-ka aluminiumku wuxuu u adeegaa sidii hordhac muhiim ah oo loogu talagalay isku-darka nanoparticles-ka aluminium oksaydh (alumina), filimada khafiifka ah, iyo dahaarka. Isticmaalkeeda hababka sol-gel wuxuu suurtogal ka dhigayaa sameynta agabyo ku salaysan alumina saafi ah oo sarreeya oo leh daloolo la xakameeyey, xasillooni kuleyl, iyo sifooyin muuqaal ah, taasoo ka dhigaysa mid qiimo leh codsiyada elektaroonigga, indhaha, iyo injineernimada dusha sare. Intaa waxaa dheer, isku-darka dabiiciga ah, Isopropoxide-ka aluminiumku wuxuu u shaqeeyaa sidii katalis Lewis acid ah, isagoo fududeynaya isbeddello kala duwan sida Friedel-Crafts acylation, alkylation, iyo falcelinta wareegga. Awooddeeda ay ku horumarinayso sameynta isku-xidhka xulashada iyo wax-ka-beddelka kooxda shaqaynaysa waxay kor u qaadaysaa hufnaanta waddooyinka isku-dhafka ah, taasoo awood u siinaysa diyaarinta molecules-ka dabiiciga ah ee adag, alaabada dabiiciga ah, iyo dhexdhexaadiyeyaasha dawooyinka oo leh wax-soo-saar iyo xulasho wanaagsan. Intaa waxaa dheer, Isopropoxide-ka aluminiumku wuxuu helaa codsi ku saabsan soo saarista polymers-ka gaarka ah iyo agabka isku-dhafan iyada oo loo marayo hababka polymerization-ka ee la xakameeyey. Iyada oo u dhaqmaysa sidii bilow ama wakiil isku xidha, waxay saamaysaa kinetics-ka polymerization-ka iyo sifooyinka nidaamyada polymeric-ga, taasoo horseedaysa sameynta agab loo habeeyay oo leh astaamo farsamo, kuleyl, iyo kiimiko oo gaar ah oo ku habboon codsiyada dhejisyada, dahaarka, iyo qaybaha qaab-dhismeedka. Intaa waxaa dheer, isopropoxide-ka aluminium waxaa loo isticmaali karaa farsamooyinka wax ka beddelka dusha sare si loo xoojiyo isku-xidhka, qoyaanka, ama iska caabbinta daxalka ee substrate-yada warshadaha sida baabuurta, hawada sare, iyo dhismaha. Awooddeeda ay ku samayn karto dahaarka dusha sare ee deggan iyo lakabyada shaqeynaya waxay gacan ka geystaan ​​​​horumarinta waxqabadka agabka, cimri dhererka, iyo shaqeynta codsiyada injineernimada kala duwan. Guud ahaan, isopropoxide-ka aluminium wuxuu u adeegaa qayb badan oo aan laga maarmi karin oo ku jirta isku-darka agabka, isbeddellada dabiiciga ah, iyo injineernimada dusha sare, isagoo siinaya fursado abuurista agabyada horumarsan, kiimikooyinka wanaagsan, iyo dusha sare ee shaqeynaya. Codsiyada kala duwan waxay hoosta ka xariiqayaan muhiimaddeeda inay tahay baloog aasaasi ah oo ku saabsan horumarinta tignoolajiyada cusub, agabka waxqabadka sare leh, iyo xalalka kiimikada ee gaarka ah ee qaybaha sayniska iyo warshadaha.
