Abstract: The solubility of the ClCH2CH2PO(OH)2 – NH2NHCNHNH2 * H2CO3 -Н2О system has been studied in the temperature range from freezing -47.6 ? to 40 ?. A polythermal solubility diagram has been constructed, on which ice crystallization fields, ClCH2CH2PO(OH)2, NH2NHCNHNH2 * H2CO3, and compounds of the composition ClCH2CH2PO(OH)2•NH2NHCNHNH2. are distinguished. The compound was isolated from the putative crystallization region and identified by chemical and physicochemical analysis methods.
Key words: solubility diagram, 2-chloroethyl phosphonic acid, aminoguanidine carbonate, effective defoliants, concentration, system, polytherm.
