Ethyl silicate CAS 78-10-4
Ethyl silicate waxa kale oo loo yaqaan tetraethyl silicate ama tetraethoxysilane. Dareere aan midab lahayn oo hufan oo leh ur gaar ah. Way xasiloon tahay marka ay joogaan walxo anhydrous ah, waxay u jajabaan ethanol iyo silicic acid marka ay biyaha la taabtaan, waxay noqdaan kuwo qallafsan hawada qoyan, waxayna ku milmaan dareeraha organic sida khamriga iyo etherka. Sun ah oo aad u xanaaqa indhaha iyo mareenka neefsashada. Waxaa lagu soo saaraa distillation ka dib falcelinta silicon tetrachloride iyo ethanol anhydrous. Waxa loo isticmaalaa samaynta dahaarka kulaylka u adkaysta iyo kiimikaad u adkaysta iyo diyaarinta dareerayaasha silikoon. Waxa kale oo loo isticmaali karaa in synthesis organic, sida alaabta ceeriin aasaasiga ah ee diyaarinta kiristaalo-fasalka sare, sida wakiilka daawaynta muraayad indhaha, binder ah, iyo sida qalab insulating ee warshadaha elektarooniga ah, iwm.

Ethyl silicate waxaa inta badan loo adeegsadaa dahaarka u adkaysta kiimikaad iyo dahaarka kulaylka u adkaysta, dareerayaasha silikoonka iyo xabagta wax soo saarka saxda ah. Hydrolysis dhamaystiran ka dib, budo silica ah oo aad u fiican ayaa la soo saaraa, taas oo loo isticmaalo soo saarista fosfooraska oo sidoo kale loo isticmaali karo sidii kiimiko. Tetraethoxysilane waxaa inta badan loo isticmaalaa muraayadaha indhaha, dahaarka u adkaysta kiimikaad, dahaarka kulaylka u adkaysta iyo xabagta. Wax ka beddelka dahaarka ka-hortagga daxalka Wakiilka Crosslinking, binder, wakiilka fuuq baxa; Soo saarista qalfoofka kicinta iyo silica ultrafine nadiif ah oo sarreeya. Ethyl orthosilicate waxaa inta badan loo isticmaalaa muraayadaha indhaha, dahaarka u adkaysta kiimikaad, dahaarka kulaylka u adkaysta iyo xabagta. Wax ka beddelka dahaarka ka-hortagga daxalka Wakiilka Crosslinking, binder, wakiilka fuuq baxa; Soo saarista qalfoofka kicinta iyo silica ultrafine nadiif ah oo sarreeya.
