ABSTRACT:
A urea-containing reactant is pyrolyzed under controlled temperature conditions of from about 100.degree. to about 150.degree. C. in the presence of an inert hydrocarbon carrier liquid having a boiling point at about the predetermined reaction temperature thereby providing an autocondensation product mass rich in biuret and having a relatively low residual content of unconverted urea. Other autocondensation pyrolyzates, less desired in the product when it is used as a protein supplement for ruminant feeds, are coproduced only in relatively low tolerable amounts.
