Microwave-Assisted In Situ Synthesis of Poly L-Lactic Acid with Nanoparticles of Calcium Phosphate was written by Pandey, Anurag;Aswath, Pranesh. And the article was included in International Journal of Polymeric Materials in 2010.Category: alcohols-buliding-blocks This article mentions the following:
A microwave reactor was used to polymerize lactic acid and/or calcium lactate in the presence of phosphoric acid or ammonium hydrogen phosphate. The polar nature of lactic acid makes it a strong absorber of microwave radiation, and when present in a nonpolar solvent such as chloroform, it is possible to conduct the polymerization reaction in a microwave reactor. Using calcium lactate and ammonium hydrogen phosphate it is possible to create nanoparticles of calcium phosphate within the matrix of poly lactic acid in situ during the polymerization FTIR spectroscopy and gel permeation chromatog. were used to follow the polymerization process, and TEM was used to determine the size distribution of the calcium phosphate particles. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Category: alcohols-buliding-blocks).
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.Category: alcohols-buliding-blocks
