Investigation of the thermal decomposition of some calcium salts used in medicine was written by Wesolowski, M.;Konarski, T.. And the article was included in Chemia Analityczna (Warsaw) in 1996.Quality Control of Calcium 2-hydroxypropanoate pentahydrate This article mentions the following:
The thermal decomposition of several calcium salts of organic acids used in medicine, lactate pentahydrate, gluconate hydrate, lactogluconate, pantothenate, cyclobarbital and cardiamid trihydrate was investigated. Sample weights were from 20 to 200 mg, and the heating rate was from 3 to 15 K min-1. The thermal decomposition of calcium salts occurred via several stages. The stages of dehydration of hydrates and of decarboxylation of calcium carbonate are distinctly marked on the thermoanal. curves, which may be used for the control of composition of the studied compounds The ranges of temperature, in which the analyzed compounds can be transformed without any change of their physicochem. properties, were established. A possibility of application of the Kissinger’s equation for calculating the parameters of the decomposition kinetics was indicated as well. For chemometric evaluation of the results, the principal component anal. (PCA) was applied. By this method the influence of heating rate and sample size on the thermal decomposition of the compounds was determined In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Quality Control of Calcium 2-hydroxypropanoate pentahydrate).
Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Quality Control of Calcium 2-hydroxypropanoate pentahydrate
