NEUES POLYCHLORID ODER POLYCHLOROSULFAT VON ALUMINIUM, VERFAHREN ZU IHRER HERSTELLUNG UND IHRE VERWENDUNG IN WASSERBEHANDLUNG

摘要

A new aluminium poly-chloride or poly-chloro-sulphate has formula Al(OH)xCly(SO4)zMt (I). The <27>Al NMR spectrum of (I) includes a signal at delta = -6 ppm. M = alkali or alkaline earth metal; x = 1.80-2.30; z = 0-0.050; t = 0.200-0.515; x+y+2z = 3 +2t if M = alkaline earth; or x+y+2z = 3 + t if M = alkali metal.
