USP-grade anhydrous magnesium carbonate is used as a flavor impression intensification vehicle in the processed food industry (see Flavors and spices). Basic magnesium carbonates are used as free flowing agents in the manufacture of table salt, as a hulking agent in powder and tablet pharmaceutical formulations, as an antacid, and in a variety of personal care products (see Pharmaceuticals). 

Formula MgCOs MW 84.31 several hydrated and basic carbonates are also known that are stable and occur in nature. The types, names, formulas and CAS Registry numbers of anhydrous, hydrated and basic magnesium carbonates are tabulated below ... 

Under ordinary conditions, anhydrous magnesium carbonate cannot be prepared in aqueous systems. The anhydrous salt, however, can be made under very high partial pressures of carbon dioxide.

I-Alkoxyhydroperoxides. Rieche and Bischoff preffared anhydrous hydrogen peroxide by treating a solution of 60 g. of 84% peroxide in ether with anhydrous sodium sulfate and magnesium carbonate. After 2 days the mixture was filtered and an aliquot titrated. One equivalent of an acetal was added to 1 equivalent of the ethereal solution, and the mixture was heated cautiously at 70°. The ether was allowed to distil to give a mixture of the acetal and the anhydrous reagent. After a reaction period of about 15 hrs. at 70°, the 1-alkoxyhydroperoxide was isolated in yields in the range 40-70%. 

The exothermic effects associated with some dehydrations [18] may result from delayed reciystallization, or the oxidation of a product of dehydration. Dehydration of magnesium carbonate trihydrate, followed by heating in carbon dioxide, resulted in the exothermic transformation of an anhydrous pseudomorph of the reactant into magnesite, MgCOj.
