Abstract
In one method of production, tetrachlorethane or trichlorethylene and aniline in aqueous suspension are heated with an alkali such as milk of lime to 140-190 DEG C. until the conversion of the intermediate bodies such as ethylene-triphenyltriamine into phenyl glycine compounds is complete. An autoclave provided with an agitator may be used. After 24 hours' heating, the excess of aniline may be distilled off, and the residue cooled and filtered. The solid product may be converted into an alkali salt of phenylglycine, and the small quantity of the calcium salt remaining in the filtrate may be precipitated as the ferrous salt. In another method, ethylene-triphenyltriamine and a caustic alkali or alkaline earth are heated together. Specifications 678/06, 5013/07, 5014/07, and 13176/07 are referred to. According to the Provisional Specification, phenyl glycine anilide may be obtained as an intermediate product in the first method, also, alkali hydrates, carbonates, silicates, aluminates, and zincates are suitable alkalies.
