Abstract
A fine granular oxidated silicon compound will react chemically with organic monohydroxy compounds in the presence of an alkali catalyst to produce organic silicate compounds.
Claims20
The process for the production of the reaction products oxidated silicon compounds with an organic monohydroxy compound by the following steps:
- (a) mixing about 1 part by weight of an oxidated silicon compound with 1 to 3 parts by weight of an organic monohydroxy compound;
- (b) adding an alkali catalyst in the amount of 1% to 10% by weight, percentage based on the weight of the oxidated silicon compound;
- (c) heating said mixture to just below the boiling temperature of the monohydroxy compound while agitating at ambient to 60 psig of pressure for 20 to 60 minutes, thereby
- (d) producing an organic silicate compound.

The process of claim 1 wherein additional steps are taken after step (d) to produce a poly(isocyanate silicate) solid/fine cellular solid product by the following steps:
- (e) mixing about 1 part by weight of the organic silicate compound as produced in claim 1 and 1 to 6 parts by weight of a polyisocyanate;
- (f) heating to 20.degree. to 60.degree. C while agitating for 10 to 20 minutes, thereby
- (g) producing a poly(isocyanate silicate) prepolymer;
- (h) adding a curing catalyst in the amount of 0.01 to 2 parts by weight to 1 part by weight of the poly(isocyanate silicate) prepolymer, then thoroughly mixing, thereby
- (i) producing poly(isocyanate silicate) solid/fine cellular solid product.
