Claim 1
Independent Claim
119 words
A METHOD OF HYDROLYZING AN ORGANOSILANE, WHICH COMPRISES MERGING A CONTINUOUS AQUEOUS LIQUID STREAM WITH A CONTINUOUS ANHYDROUS LIQUID STREAM COMPRISING THE ORGANOSILANE, TO FORM A LIQUID REACTION STREAM, CONTINUOUSLY CONDUCTING THE REACTION STREAM AWAY FROM THE POINT OF MERGER TO KEEP THE FINAL PRODUCTS OF THE REACTION OUT OF CONTACT WITH THE INITIAL PRODUCTS OF THE REACTION AND OUT OF CONTACT WITH THE REACTANT, AND MAINTAINING THE FLOW OF THE REACTION STREAM UNTIL THE REACTION IS SUBSTANTIALLY COMPLETE, SEPARATING THE HYDROLYZED ORGANOSILICON PRODUCT FROM THE AQUEOUS PHASE, SAID AQUEOUS LIQUID STREAM COMPRISING SUFFICIENT WATER TO CONSTITUTE AT LEAST 5 GRAM MOLS THEREOF FOR EVERY TWO GRAM ATOMS OF HYDROLYZABLE GROUP IN THE SILANES CONTAINED IN THE ANHYDROUS STREAM.
