Supercritical Fluid Carbon Dioxide in the Extraction of Lanolin and Its Alcohol

The use of supercritical fluid carbon dioxide (SF-CO_2) in extraction of lanolin and its alcohol issuperior to the conventional solvent extractionmethod. Its distinctive advantages include highextractive ratio, nontoxic and nonflammablesolvents, and minimal by-product pollution. The     

Isolation of a cytochrome of the antimycin a sensitive pathway for DPNH oxidation

Zusammenfassung Ein neues Cytochrom ist aus Schweineleber isoliert worden. Es wird durch DPNH-Cytochrom-c-Reduktase reduziert. Antimycin A hemmt diese Reaktion, die nur in Gegenwart des Slater-Faktors abläuft.Es ist wahrscheinlich, dass dieses Cytochrom in die Elektronentransportreihe, und zwar zwischen Reduktase und Cytochrom c, eingeschaltet ist.     

Synthesis of Water-dispersed Polyurethane Adhesive and Its Application in Pigment Printing

Water-dispersed polyurethane (PU) adhesive is a novel and highly efficient adhesive with broad application potential. In this study, the key parameters affecting the synthesis and application of this adhesive were examined, and optimal conditions were identified. The water-dispersed PU adhesive was successfully synthesized, and applied in the fastness test of pigment printing on cotton fabric. The data demonstrated that all the fastnesses of PU adhesive were better than that of the cenventional PA one.
