Beschreibung
Zusammenfassung:	NEW MATERIAL:A complex compound of calcium octaphosphate and an organic acid expressed by the formula (R is methylsuccinic ion, citraconic acid ion, beta- dihydromuconic acid ion, phthalic acid ion or isophthalic acid ion; Z is larger than 0 and 1 or below; m is an integer 5-8). EXAMPLE:Complex calcium octaphosphate with methylsuccinic acid. USE:An intermediate for complexing calcium octaphosphate with various organic compounds, simulation samples for physiological research in calcification of bones and teeth in the living body, anticaking and fluidity modifier for powder, adsorbent for chromatography of proteins or nucleic acids, plastic fillers, ion exchangers, catalysts, etc. PREPARATION:Calcium alpha-phosphate is hydrolyzed in the presence of an organic acid ions expressed by the formula R (R is ion or R) at 5-7pH to give the aimed compound expressed by the formula.
