Summary The ways in which carbon dioxide is formed in the oxidation of formaldehyde at 451 were Investigated. It was shown that not more than 3–5% of the CO2 formed can arise by the oxidation of CO. The bulk (95–91%) of the CO2 is formed directly from formaldehyde. 相似文献

The kinetics of ethane oxidation was studied at 320, 340, 353 and 380°C, mixture composition 2 C2H6 + 1 O2, and total pressure 609 torr. It was found that at 320°C CH2O and CH3CHO were branching agents. A series of experiments was conducted on 2C2H6 + O2 oxidation in the presence of 0.7% 14C-labeled ethylene. The ethylene oxide was found to form only from C2H4, formaldehyde formed from C2H4 and C2H6; and CH3CHO, C2H5OH, and CH3OH formed only from ethane. The formation rates of C2H4, C2H4O, and CH2O were calculated by the kinetic tracer method. At 320°C the fraction of oxygen-containing products formed from C2H4 was 16–18%, and at 353 and 380°C it was 30–40%. 相似文献

Electroflotation of poorly soluble lanthanum compounds from model solutions simulating with high accuracy highly concentrated industrial salt systems was studied. The influence of various kinds of microadditives (flocculants and surfactants; cationic, anionic, and nonionic) on the efficiency of the recovery of lanthanum compounds from highly concentrated salt solutions was examined. For each supporting electrolyte (chloride, carbonate, sulfate, oxalate, nitrate), additives intensifying the process and enhancing its efficiency were found. The mean size and ζ-potentials of the dispersed phase particles were measured to account for the degrees of recovery reached in lanthanum electroflotation. A design of an installation for lanthanum recovery, allowing solution processing on the commercial scale, was suggested. 相似文献
