HCID 712FormaldehydeHCID 17524-NonylphenolHCID 5054Resorcinol

Procedure

Resorcinol and nonyl phenol are reacted with formaldehyde in the presence of a catalytic amount of hexamethylenetetramine at a total phenol:formaldehyde molar ratio of 1.7:1 to afford a novolak cocondensate resin (97 mole % resorcinol/3 mole % nonylphenol). The solid resin is washed to remove formaldehyde odor. The wet resin is dried under vacuum. The dry resin is dispersed in water with sodium caseinate at 40% N.V. to afford Emulsion A.
