Abstract

Methods have been developed which allow of full analysis of the known basic products formed in the reaction between aqueous ammonium salts and formaldehyde, namely of ammonia, mono‐, di‐, and trimethylamines, and the condensation products of formaldehyde with mono‐ and dimethylamines. The methods have advantages Were those already proposed in that concentration of the solution of salts, which leads to changes in composition, is avoided.

A method is also described for the approximate determination of the formic acid content of the reaction product.
