Abstract
Phenol compounds and silicoformic acid will chemically react to produce a phenol silicoformate when heated with a suitable alkali catalyst. The phenol silicoformate compounds are then chemically reacted with an aldehyde to form a condensation product.
Claims15
The process for the production of phenol silicoformate compounds by the following steps:
- (a) mixing silicoformic acid and a phenol compound,
- (b) adding an alkali catalyst equal to 1 to 10% by weight of silicoformic acid and phenol compound,
- (c) heating said mixture to just below the boiling point of the phenol compound for 20 to 80 minutes while agitating at ambient pressure, thereby
- (d) producing a granular phenol silicate compound.
