A mixt. of calcium sucrose phosphate and calcium phosphate is recovered from the aq. reaction liquors obtd. by phosphorylating sucrose by drying the liquors in such a manner as to obtain a finely divided powder, sepg. CaCl2 and sucrose by lixiviation with a suitable solvent and drying the lixiviated residue. The Ca-mixt. is used in the prevention of dental caries. The process is more economical than known processes involving removal of CaCl2 by pptn. methods. The product contains less than 0.5% CaCl2 and is non-deliquescent. |
