摘要
A preparation method of ethylenediamine core, octamethylenephosphonic acid terminated, PAMAM dendrimer and application thereof is provided, wherein terminal amino groups of ethylenediamine core, 0 generation, PAMAM dendrimer is modified by methylene phosphonic acid. The ethylenediamine core, octamethylenephosphonic acid terminated, PAMAM dendrimer has an excellent performance to inhibit scales of CaCO3, CaSO4 and Ca3(PO4)2, a very high calcium tolerance, and excellent dispersing performance. The ethylenediamine core, octamethylenephosphonic acid terminated, PAMAM dendrimer is used as an antiscalant in industrial water treatment, and is suitable for the industrial water treatment of boiler, cooling, desalination, and oil production, etc., especially for the industrial water treatment under high calcium concentration.
