Formaldehyde → Resorcinol-formaldehyde resin

関与物質

反応手順

Formaldehyde in aqueous solution is added to the granules of resorcinol silicoformate acid in the ratio of about 1 to 1 mols. Sodium hydroxide is added until the pH is between 10 to 12. The mixture is then heated to 50° to 85° C while agitating and the resorcinol silicoformate goes into solution. In 30 to 90 minutes the reaction is complete, thereby producing a formaldehyde resorcinol silicoformate resinous compound. This compound is soluble in acetone and other organic solvents.
