An improved enzymatic cotton scouring process has been developed on the basis of a fast enzyme reaction to efficiently remove the pectin and wax compounds from the organic cotton fabrics. An attempt has been made to study the pectinolytic activity of degrading rate of pectin on the organic cotton fabric using alkaline pectinase enzyme with various process parameters such as enzyme concentration...

1. Caffeine reacts with haematin to form a caffeine-haematin compound that has a characteristic absorption spectrum. 2. Graphical analysis of the titration of haematin with caffeine shows that 2mol.prop. of caffeine split the dimeric haematin. 3. Thermodynamic parameters suggest that the reaction involves the making and breaking of hydrophobic bonds. 4. Graphical analysis shows dimeric haem to ...

The PdCl(2)-promoted reactions of methylenecyclopropanes (MCPs) 1 bearing diaryl substituents on the terminal double bond were carefully investigated. The solvents employed significantly affected the reaction outcomes. It was found that dimeric allylpalladium(ii) complexes 2a-2f can be obtained as the sole products in acceptable to good yields under mild reaction conditions with THF as the solv...

Zero-, mono- and diperiodic uranyl ion complexes are formed by benzene-1,2,3-tricarboxylate, depending on the structure-directing species used, linear chains based dimeric motifs being a preferred arrangement.
