B.7 FORMALIN PRODUCTION, UNIT 800 Formalin is a 37 wt% solution of formaldehyde in water. Formaldehyde and urea are used to make urea-formaldehyde resins that subsequently are used as adhesives and binders for particle board and plywood. B.7.1 Process Description [1, 2] Unit 800 produces formalin (37 wt% formaldehyde in water) from methanol using the silver catalyst process. Figure B.7.1 illustrates the process.
