    The dicalcium phosphate dihydrate Fixator and Stabilizer of Glutaraldehyde
    (2014) Bouzid, Mohammed; Djadi, Amina; Guechtoulli, Samira
    The dicalcium phosphate dihydrate (A) reacts with glutaraldehyde (B) in aqueous solution with a yield of 95%. The resulting product (C) is chemically stable. The obtained purity is checked by UV-Visible and the structure is discussed on the basis of the Infrared absorption FTIR. The reaction mechanism is explained by the approach of the hydroxyl group (-OH) of one of the aldehyde functions (-CO) of 1.5 dipentanal with the enolic form, which stabilizes the product (C). The reversible reaction is performed by mild oxidation of the compound (C) in aqueous medium at ambient temperature. The compound (A) is generated with high efficiency. The comparative spectral and thermography study confirms this result
