Abstract
An O-alkyl isourea alkyl hydrogen sulphate is heated with a compound of the formula R.NH2, where R is an alkyl, amino, hydroxyalkyl, or aminoalkyl radical to give a guanidinium alkyl sulphate. O-Ethyl isourea ethyl hydrogen sulphate is reacted with (1) methylamine, (2) ethylamine, (3) ethanolamine, (4) ethylene diamine hydrate, and (5) hydrazine hydrate, in aqueous medium at 60 DEG C. to give methylguanidine, ethyl-guanidine, b -hydroxy-ethylguanidine, N,N1-diguanyl-ethylene-diamine and amino-guanidine ethyl sulphates respectively. The free bases may be prepared from these salts, as may also the picrates. Amino-guanidine bicarbonate may be obtained by passing carbon dioxide into an amino-guanidine solution. Specification 817,748 is referred to.
