Abstract Calcined dolomite was utilized as a low-cost and efficient catalyst for the Knoevenagel condensation of aldehydes with active methylene compounds such as malononitrile and ethyl cyanoacetate to afford substituted α, β-unsaturated carbonyl compounds. Calcination temperature was an important variable which changed the …
Calcined Dolomite is an Oxide of Calcium and Magnesium (CaO & MgO) mainly used as a flux in iron and steel industries. Calcined Dolomite play important role in purifying the …
Uses of Calcined Dolomite Animal Food. Micronized calcium carbonate is utilised as a food additive in animal feasts. For birds, a refinement in egg quality and shell hardness is acquired. Calcium soaps subsequently intended for the animal meal and used to qualify Calcium Oxide with very fine grading and high reactivity. Calcium soaps are ...
The addition of calcined dolomite increased the formation of NO more significantly due to the pores created by calcination and by the catalytic effects of CaO and MgO contained in calcined dolomite. The MgO in calcined dolomite also reacted with SO2 to form MgSO4 which was then thermally decomposed to release SO2 from 1000 …
