WASTE TREATMENT

摘要

A waste liquid including an alcohol and/or a ketone is treated to give a solid reaction product. If alcohol is present, the fluid is contacted with a monomer-free isocyanate under conditions which give a solid polyurethane. If ketone is present, the fluid is contacted with an acid, ammonium compound or bisulphite ion under conditions which give a solid reaction product, if necessary after the addition of acid.
