Kev Tshawb Fawb Daim Ntawv Thov CAS: 16646-44-9|Tetraallyloxyethane

1. Kev tsim khoom ntawm Alkoxysilanes thiab Environmental Aspects

Tetraallyloxyethane yog ib qho tseem ceeb hauv kev tsim cov alkoxysilane, tshwj xeeb tshaj yog tetraethoxysilane (TEOS). Alkoxysilanes, suav nrog TEOS, muaj ntau yam kev siv nyob ntawm seb Si-OR daim ntawv cog lus puas zoo lossis hydrolyzed. Kev tsim khoom ntawm TEOS, ib qho tseem ceeb derivative hauv tsev neeg no, ib txwm ua raws li cov tshuaj tiv thaiv esterification ntawm SiCl4. Cov txheej txheem no, hu ua Von Ebelman txoj kev, hnub rov qab mus rau 1846. Muaj kev tshawb fawb txuas ntxiv los txhim kho cov thev naus laus zis uas twb muaj lawm lossis tawm tswv yim tshiab rau TEOS ntau lawm, tsom rau ib puag ncig thiab kev lag luam ntawm cov txheej txheem no. Ib txoj kev qhia yog kev siv cov reactive distillation raws li kev siv thev naus laus zis los tsim TEOS, uas tuaj yeem muab cov txiaj ntsig zoo ntawm cov khoom siv txo qis thiab txhim kho lub zog ua haujlwm (Sánchez-Ramírez li al., 2018).

2. Cov ntawv thov hauv kev txuag pob zeb

Tetraallyloxyethane derivatives zoo li TEOS tau kawm ntau ntxiv rau kev txuag ntawm cov pob zeb keeb kwm. TEOS-based composites tau pom cov txiaj ntsig tau zoo hauv kev txuag sandstone. Cov kev tshawb fawb tau tsom mus rau kev sib xyaw ntawm nano-hydroxyapatite (n-HA) thiab TEOS rau lawv cov txiaj ntsig hauv kev sib koom ua ke thiab muab cov khoom siv hydrophobic rau sandstone. Cov khoom sib xyaw no tau raug soj ntsuam rau lawv cov khoom siv kho tshuab, tiv thaiv kev laus, thiab lawv lub peev xwm los hloov cov xim ntawm cov xuab zeb cov qauv tsawg (Luo, Xiao, & Zhang, 2015). Tsis tas li ntawd, TEOS-based composites uas muaj cov ntsiab lus ua haujlwm zoo li glycidoxypropyltrimethoxysilane thiab polyhedral oligomeric silsesquioxane tau npaj los txo cov gel tawg thaum lub sij hawm ziab, yog li txhim kho kev sib koom ua ke ntawm granite cuab yeej cuab tam (Son et al., 2009).

3. Kev tsim cov khoom siv hybrid

Kev tshawb fawb rau TEOS-raws li cov ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem sol-gel, tau coj mus rau txoj kev loj hlob ntawm hybrid organic-inorganic cov ntaub ntawv. Cov ntaub ntawv no yog tsim los ntawm kev sib xyaw ntawm trifunctional alkoxysilanes thiab TEOS. Kev npaj ntawm cov hybrids no suav nrog kev tswj cov morphology los ntawm kev hloov ib nrab ntawm TEOS nrog rau lwm cov siloxane. Cov txheej txheem no cuam tshuam rau cov khoom ntawm cov khoom tsim, xws li thermal expansion, tensile lub zog, thiab elongation ntawm tawg. Kev sib txuas ntawm silica-nplua nuj nyob rau hauv cov polyimide-nplua nuj matrix ntawm cov hybrids ua lub luag haujlwm tseem ceeb hauv kev hloov kho cov khoom siv (Mascia & Kioul, 1995).
