摘要
以磷酸、液体三氯化铝和有机胺缔合剂为原料 ,经缔合、置换、解缔制取磷酸二氢铝后 ,经加热水化制得三聚磷酸二氢铝。用X—衍射分析 ,计算机自动检索为H2 AlP3O1 0 ·2H2 O和AlH2 P3O1 0 ·(2～ 3)H2 O晶体 ,磷酸与三氯化铝的摩尔比等于 2
A new technology for the preparation of aluminium dihydrogen tripolyphosphate was described.Phosphoric acid,aluminium chloride and association agent organic amine used as raw materials,through association,replacement and dissociation,the aluminium dihydrogen,phosphate was first produced,then by heating and hydration,the aluminium dihydrogen tripolyphosphate was prepared.By x-ray diffraction,it showed that the formula of the product is H 2AlP 3O 10 ·2H 2O and AlH 2P 3O 10 ·(2～3)H 2O.
