Изобретение относитс к области получени соединений фосфора, в частности к способу нолучепи фосфата магни , который может найти применение в качестве св зующего.The invention relates to the field of the preparation of phosphorus compounds, in particular, to the method of the preparation of magnesium phosphate, which can be used as a binder.
Известен способ нолучепи фосфатов магни путем нейтрализации фосфорной кислоты окисью или гидроокисью магнн нри температуре 25-80°С при различных соотношени х PaOs и MgO.A known method for the accumulation of magnesium phosphates by neutralizing phosphoric acid with magnium oxide or hydroxide is at a temperature of 25-80 ° C at different ratios of PaOs and MgO.
С целью нолучени в зкого нродукта нредложено нагревание раствора вести нри температуре около 200°С в течение 20-30 мин до получени раствора в зкостью 35-40 пуаз.In order to obtain a viscous product, it is proposed to heat the solution at a temperature of about 200 ° C for 20-30 minutes until the solution has a viscosity of 35-40 poise.
Соотношение PsOs : MgO при нейтрализации термической фосфорной кислоты окисью или гидроокисью магни поддерживают в пределах 5-10: 1 нри концентрацнн кислоты 80-90%.The ratio of PsOs: MgO at neutralization of thermal phosphoric acid with oxide or magnesium hydroxide is maintained within the range of 5-10: 1 at a concentration of acid of 80-90%.
Пример. В трехгорлую колбу емкостью 0,5 л засынают 5,85 г гидроокиси магнии и вливают затем 78,6 мл терм11,ческой фосфорной кислоты удельного веса 1,72; соотношение P.205:MgO G: 1. Содержимое колбы нагревают нри носто нном перемешивании прн темнературе 100-110°С в течение 30 мин. Затем новышают температуру до 200-230°С и выдерживают раствор в течеиие 30 мин до нолучепи раствора в зкостью 35-40 пуаз. Получают смолоподобное полпмерное вещество .Example. In a three-necked flask with a capacity of 0.5 l, 5.85 g of magnesium hydroxide are injected into the flask and then 78.6 ml of thermal 11, chesic phosphoric acid with a specific gravity of 1.72; the ratio of P.205: MgO G: 1. The contents of the flask are heated by in situ stirring at a temperature of 100-110 ° C for 30 minutes. Then, the temperature is increased to 200–230 ° C and the solution is kept for 30 minutes until the solution reaches a viscosity of 35–40 poises. A gum-like half-dimensional substance is obtained.
