Can hydroxy silicone oil directly add organic tin can be fixed?
Titanium hydroxyl and silicon hydroxyl can condensation reaction: dehydration condensation reaction.
(In general, acid and base can catalyze it. The silicone hydroxyl groups formed by the hydrolysis of organosilanes are so active that they can condense with each other even without a catalyst. The silicone hydroxyl groups on many substrates, such as mineral surfaces, are protected by hydrogen bonds, mineral layers, etc., and may require some acid-base or temperature to stimulate condensation with other hydroxyl groups.) The condensation of hydroxyl silicone oil with other hydroxyl groups can use organotin as a catalyst, but water-soluble catalysts are not.
