Abstract

Phenol and formaldehyde are condensed together with the material obtained by hydrolyzing a protein with mineral acid and removing glutamic acid from the hydrolysate, using as catalyst the mineral acid already present. The product may be moulded or used as a raw material for moulding compositions. In an example: crude soya bean protein is hydrolyzed by hydrochloric or sulphuric acid, the glutamic acid crystallized out, water, phenol, and formalin added, and the mixture heated.
