WitrynaThe alkali-silica reaction mechanism catalysed by a soluble strong base as NaOH or KOH in the presence of Ca (OH) 2 (alkalinity buffer present in the solid phase) can be compared with the carbonatation process of soda lime. The silicic acid ( H 2 SiO 3 or SiO 2) is simply replaced in the reaction by the carbonic acid ( H 2 CO 3 or CO 2 ). Witryna28 sty 2024 · The mechanism for both reactions start by making the alcohol's -OH a better leaving group through conversion to an intermediate. Thionyl chloride creates an intermediate chlorosulfite (-OSOCl 2) compound and phosphorus tribromide makes an intermediate dibromophosphite (-OPBr 2) compound.
