The recycling method comprises the following steps: a, reacting, wherein a mixture formed by mixing the low-boiling point matters with mud slurry or low-boiling point matters are used as materials to react with TiO2, reaction equation is as follows: TiO2+SiCl4=TiCl4+SiO2, and in the ...
point where substantially all the SiCh has been consumed in the reaction, and the temperature is then raised to about 60* C., and held there for 8 hours. This heating step presumably promotes the reaction of the excess phenol with any phenoxy silicon chlorides which may have been formed, ...
CONSTITUTION: A method for preparing mono-silane of formula; RyHzSiCl4-y-z from residues with high boiling point comprises reacting the residues with high boiling point which are prepared by the reaction of organochloride and silicon metal with a catalyst composition consisting of hydrogen chloride...
