Kuphononongo lwe-kinetic lokusabela kweekhemikhali ezikhawulezayo, ukujonga kwi-intanethi kwi-intanethi kuphela kwendlela yophando
I-in situ Raman spectroscopy inokumisela ngokobungakanani kinetics ye-base-catalyzed hydrolysis ye-methyltrimethoxysilane.Ukuqonda okunzulu kwe-hydrolysis reaction ye-alkoxysilanes kubaluleke kakhulu kwi-synthesis ye-silicone resins.I-hydrolysis reaction ye-alkoxysilanes, ngakumbi i-methyltrimethoxysilane (MTMS), phantsi kweemeko ze-alkaline ikhawuleza kakhulu, kwaye ukuphendula kunzima ukuphelisa, kwaye ngexesha elifanayo, kukho ukuphendulwa kwe-hydrolysis kwi-system.Ke ngoko, kunzima kakhulu ukumisela i-kinetics yokuphendula usebenzisa iindlela zohlalutyo eziqhelekileyo ngaphandle kweintanethi.I-in-situ Raman spectroscopy ingasetyenziselwa ukulinganisa utshintsho lomxholo we-MTMS phantsi kweemeko ezahlukeneyo zokusabela kunye nokwenza uphando lwe-alkali-catalyzed hydrolysis kinetics.Ineenzuzo zexesha elifutshane lokulinganisa, uvakalelo oluphezulu kunye nokuphazamiseka okuncinci, kwaye inokubeka iliso kwindlela yokusabela ngokukhawuleza kwe-hydrolysis ye-MTMS ngexesha langempela.
Ukubekwa kweliso kwexesha lokwenyani kwenkqubo yokunciphisa inkqubo ye-MTMS ekrwada kwimpendulo ye-silicone ukujonga inkqubela ye-hydrolysis reaction.
Utshintsho kwi-MTMS yoxinzelelo kunye nexesha lokuphendula phantsi kweemeko ezahlukeneyo zokuqala, utshintsho kwi-MTMS yoxinaniso kunye nexesha lokuphendula kumaqondo okushisa ahlukeneyo.
