The Calcium acetate is an organic compound with the formula C4H6CaO4. The IUPAC name of this chemical is calcium diacetate. With the CAS registry number 62-54-4, it is also named as Diacétate de calcium . The product's classification codes are Chelating Agents; Mutation Data; Pharmaceutic Aid [buffering agent]. Besides, it is a white crystals or powder, which should be stored in a closed and dry place. It is mainly used in candy products as a food additive.
Physical properties about Calcium acetate are: (1)ACD/LogP: -0.29; (2)ACD/LogD (pH 5.5): -1.07; (3)ACD/LogD (pH 7.4): -2.86; (4)ACD/BCF (pH 5.5): 1; (5)ACD/BCF (pH 7.4): 1; (6)ACD/KOC (pH 5.5): 2.73; (7)ACD/KOC (pH 7.4): 1; (8)#H bond acceptors: 2; (9)#H bond donors: 1; (10)Polar Surface Area: 37.3 Å2; (11)Flash Point: 40 °C; (12)Enthalpy of Vaporization: 23.7 kJ/mol; (13)Boiling Point: 117.1 °C at 760 mmHg; (14)Vapour Pressure: 13.9 mmHg at 25°C.
Uses of Calcium acetate: it was formerly used to manufacture acetone by thermal decomposition:
Ca(OCOCH3)2 → (CH3)2C=O + CaO + CO2
Preparation: this chemical can be prepared by the reaction of calcium carbonate or calcium hydroxide with acetic acid.
Ca(OH)2 + CH3CO2H → Ca(OCOCH3)2 + 2H2O
