Tus nqi muag khoom Ethyl Silicate Cas 11099-06-2
Ethyl silicate, tseem hu ua tetraethyl orthosilicate, tetraethyl silicate thiab tetraethoxysilane, muaj ib tug molecular mis ntawm Si (OC2H5) 4, ib tug tsis muaj kob pob tshab kua nrog ib tug tshwj xeeb tsw.txheeb ze ntom ntom 0.933, melting point - 77 ℃, boiling point 166.5 ℃, freezing point - 77 ℃, viscosity 0.00179Pa · s [0.0179P (20 ℃)], refractive index 1.3837 (20 ℃).Nws yog ruaj khov nyob rau hauv lub xub ntiag ntawm tsis muaj dej, decomposes rau hauv ethanol thiab silicic acid nyob rau hauv lub xub ntiag ntawm dej, ua turbid nyob rau hauv cov huab cua noo, qhia meej tom qab sawv, thiab precipitates silicic acid, uas yog soluble nyob rau hauv cawv, ether thiab lwm yam organic solvents.
