Dimethyl carbonate is a crucial ingredient in the production of polycarbonates. As a result of the growing use of polycarbonates, it is predicted that the demand for dimethyl Carbonate will expand rapidly over the coming years. In addition to the aforementioned uses, increasing polycarbonate use in medical devices, lighting equipment, electronics, optical media, and other products is a major factor in the growth. It is a flammable, colorless liquid that is frequently known as a "green reagent." The substance is created industrially through the transesterification of ethylene carbonate or propylene carbonate with methanol, and researchers have found that it serves as a methylating agent as well as a component of coatings, adhesives, and cleaning products.From natural sources, pure calcium carbonate is extracted using a variety of methods, including mining and quarrying. Currently, calcium carbonate serves a variety of purposes, including those of a mineral filler, a bleaching agent, and an alkalizing agent.
More than 4% of the earth's crust is made up of the white, insoluble mineral calcium carbonate, which also forms mollusk shells and occurs naturally as limestone, chalk, calcite, and marble. It is frequently employed as a stomach antacid, in the production of lime, and Portland cement. Additionally, calcium carbonate pills and calcium carbonate antacids are widely utilised as dietary supplements.
