Formaldehyde → HCID 131710823, compound

Participants

Reaction Steps

One mol of monosilandiol, one mol of phenol and 0.2 mol of potassium hydroxide are mixed then heated to just below the boiling point of phenol while agitating at ambient pressure for 15 to 60 minutes, thereby producing phenol monosilandiol, a tan granular compound. The phenol monosilandiol is mixed with about 1 mol of formaldehyde in an aqueous solution, then heated to 70° to 90° C. for 20 to 100 minutes until the desired viscosity is obtained, thereby producing poly(formaldehyde phenol monosilandiol) resin. The resin may be produced as a thick liquid, soft solid or a hard solid. The resin is soluble in acetic acid, acetone and other organic solvents, and a solution of the resin may be used as an adhesive or coating on wood.
