Abstract:
A process for preparing calcium magnesium acetate includes such steps as mixing Ca and Mg compound (the mole ratio of Ca:Mg is 3-4:6-7) with solution of acetic acid, to form a solution with concentration of (3-5) mol/L, reaction at 40-90 deg.C for 1-3 hr, filtering, vacuum distilling concentration at 45-90 deg.C and under -0.08-0.1 MPa for 1-5 hr, and drying. Its advantages are simple process, low reaction temp. and high purity of product.
