SURFACE ACTIVE CALCIUM PHOSPHATES |
摘要 |
A nitrogen complex of an inorganic phosphate comprising the anionic sub-structure (I); whereby a nitrogen atom (N) of a complexing agent is complexed to an oxygen atom (O) of the inorganic phosphate; wherein the nitrogen atom is selected from the group consisting of a nitrogen atom of an amine group or a nitrogen atom of a N-heteroaromatic ring; and wherein A and A' are each independently selected from the group of constituents consisting of a hydroxyl group (-OH), an oxide group (-O<SUP>-</SUP>), the group -OR where R is alkyl or substituted alkyl; an oxygen to which a nitrogen is complexed (-0<-N) wherein the nitrogen atom is selected from the group consisting of a nitrogen atom of an amine group or a nitrogen atom of a N-heteroaromatic ring; and a phosphate of the form (i); wherein each of A'' and A''' are selected independently from the same group of substituents as A and A'; wherein at least one of A, A', A'' and A''' is an oxide (-O<SUP>-</SUP>) with the proviso that when A' and A''' are not present then at least one of A and A' is an oxide (-O<SUP>-</SUP>). |
