Abstract: front page image
(EN)In order to obtain hydrochloric salts of 2,5,6 triamino-4(1H)-pyrimidinone (CAS-Nr. 51 325-37-9), presenting only a minimum ratio of foreign organic compounds, by reaction of the reduction product of 2,6 diamino-5-nitroso-4(1H)-pyrimidinone with hydrogen chloride, the process is carried out at a temperature of at least 60?o¿C, in a reaction medium comprising water, hydrogen chloride and isopropyl alcohol with such proportions that the concentration of isopropyl alcohol is at least 20% by weight.
(FR)En vue d'obtenir les sels chlorhydrates de la 2,5,6 tri-amino-4(1H)-pyrimidinone (no d'enregistrement C.A. 51 325-37-9), ne présentant qu'un taux minimal en composés organiques étrangers, par réaction du produit de réduction de la 2,6 di-amino-5-nitroso-4(1H)-pyrimidinone avec la composante chlorhydrique, l'on procède à température d'au moins 60?o¿C, en un milieu de réaction réunissant l'eau, l'alcool isopropylique et la composante chlorhydrique en de telles proportions que le taux en alcool isopropylique atteigne au moins 20% en poids.
