Abstract
The invention comprises a new compound ferro-calcium citrate of formula CaFe2(C6H5O7)2. It is produced by reacting an aqueous solution of citric acid with ferrum reductum and a calcium salt such as the carbonate or citrate. The citric acid may first be reacted with tricalcium citrate in aqueous solution to form acid calcium citrate which is then treated with ferrum reductum. Alternatively acid ferro-citrate may be reacted with a calcium salt. Preferably oxygen should be excluded during the reaction. In the examples (a) citric acid is treated with ferrum reductum to give acid ferro-citrate which is reacted with calcium carbonate to give ferro-calcium citrate; (b) citric acid is treated with tricalcium citrate and the acid calcium citrate so formed is then treated with ferrum reductum to give ferro-calcium citrate.
