U.; Zhanabaeva, A. K.. HPLC of Formula: 13395-16-9This research focused ontributyl phosphate catalytic phosphorus extractant. The article conveys some information:
By kinetics, volumetry, gas chromatog., elemental anal., IR, NMR spectroscopy the oxidative alkoxylation of yellow phosphorus to phosphorus esters in alc. solutions of copper and iron salts was studied using oxygen as an oxidant. The effect of temperature, oxygen partial pressure, nature and concentration of reagents was investigated on the phosphorus conversion. The novelty and relevance of research is associated with the development of “”chlorine-free”” direct syntheses of esters of phosphorus acids from phosphorus and alcs. It was established that copper halides are characterized by the highest catalytic activity at a 5-10 optimal ratio of CuX2/P4 and a temperature of 60°C. The partial pressure of oxygen does not significantly affect the yield of phosphorus acid esters. Enlarged laboratory tests of the catalytic synthesis of tri-Bu phosphate from yellow phosphorus and butanol were carried out under optimal conditions, in which the amount of phosphorus added to the reaction was increased 20-40 times as compared with exptl. studies. After reading the article, we found that the author used Bis(acetylacetone)copper(cas: 13395-16-9HPLC of Formula: 13395-16-9)
Bis(acetylacetone)copper(cas: 13395-16-9) catalyzes coupling and carbene transfer reactions. Metal acetylacetonates are used as catalysts for polymerization of olefins and transesterification. HPLC of Formula: 13395-16-9
