The extraction kinetics and mechanism of La(III) by P204-kerosine from phosphoric acid were investigated by constant interfacial cell with laminar flow. The effects of stirring speed, temperature, specific interface area on extraction rate were studied. The results indicated that a "plateau region" is appeared at the stirring speed of over 115r/min. The extraction apparent activation energy was calculated to be -13.40kJ/mol and the extraction process is controlled by a mixed mechanism of diffusion and chemical reaction. The rate equation of extraction was deduced. Under conditions of 25°C and interfacial area 19.64cm2, the extraction rate constant was 2.08×10-6 m·s-1·. Through the derivation of the reaction mechanism the reaction zone is at the liquid-liquid interface. © (2014) Trans Tech Publications, Switzerland. Source

This article introduces EU, USA and Japan safety regulatory system for alcoholic products, and illustrates on the specific regulations of the country's alcoholic labels. It analyzes the alcoholic products export with Sichuan liquor as examples. Two suggestions are proposed for export enterprises because alcoholic products export disruption: first, it is concerned from various channels in time on the export destination the change of the country's labeling requirements by export enterprises, and the export products label must be in strict accordance with the foreign label requirements. Second, government and research institutions should increase research efforts on foreign labeling requirements, in particular, the trend of the label, and notification is timely forwarded to the enterprise. At the same time, government should supervise and guide enterprises to carry out notifications of alcoholic labels. Source
