| | CALCIUM ACETATE HYDRATE Usage And Synthesis |
| Chemical Properties | White powder or agglomerates | | Uses | Calcium acetate hydrate is used as a precursor to produce calcium ions in the development of calcium oxide based mesoporous carbon dioxide sorbent. It is an active component of pyroligneous acid-modified limestone. It is employed in the preparation of magnetite-calcium phosphate core-shell nanoparticles. It serves as a raw material in the preparation of hydroxyapatite-wollastonite composites. Further, it acts as a crosslinking agent in the microfluidic production of alginate hydrogel microbeads. In addition to this, it is used to induce crystallization of proteins. | | Synthesis | a. Add anhydrous calcium acetate to the aqueous calcium acetate solution, stirring while adding, to obtain the mixture, followed by keeping the mixture at 20C and continuing to stir for 5h; wherein the material-liquid ratio of the aqueous calcium acetate solution is 0.1g/mL and the pH is 4;
b. the substance obtained in step a was subjected to filtration until the filtrate could not be filtered out;
c. naturally drying the filter cake obtained in step b at 18C and 45% RH until constant weight is sufficient, wherein the condition of constant weight is a weight difference of 0.2 mg. its purity is 95.6%. |
