Formaldehyde → HCID 67111990, compound

Participants

Reaction Steps

The tan granules of phenol silicate as produced in Example I are mixed in 75 parts by weight of an aqueous solution containing 37% formaldehyde heated at 65° to 100° C. for 10 to 90 minutes while agitating until the desired viscosity is obtained. The tan granules of phenol silicate go into solution and react chemically with the formaldehyde, thereby producing a red resin, poly(formaldehyde phenol silicate). The said resin may be produced in a thick liquid form, in a soft solid resin, or if heating continues, the resin will form a hard insoluble resin. A reflux condenser and a vacuum may be used to remove the water.
