 Title    Ein neues Verfahren zur Bestimmung kleinster Mengen H20 mittels Ph3P und CC14 [1] A New Way to Determine Smallest Amounts of H20 by Means of Ph3P and CCI4 [1]  
 Abstract    A new and easier method of water determination in numerous organic solvents is founded on the measurement of the electrical conductivity in the system PI13P/CCI4/H2O, that is characterised by a typical maximum minimum pattern. The time interval up to the registration of the well-defined minimum is proportional to the amount of water which can be determined down to concentrations of 10 _3 %.

 Title    Effect of Organic Solvents on Enzymatic Hydrolysis of Celluloses  
 Abstract    Effect of organic solvents on enzymatic hydrolysis of celluloses was studied. It was found that toluene and xylene can accelerate the rate of the enzymatic hydrolysis reaction of filter paper and cellulose powder. The addition o f N,N-dimethylformamide, acetone, and alcohols was negative effect for the enzymatic hydrolysis o f solid celluloses. In the addition o f alcohols and glycols, the relative glucose yields increased with increasing the carbon number o f their solvents. The addition o f organic solvents on the enzymatic hydrolysis of celluloses was discussed with swelling effect. It was found that the glucose yield increased as the dipole moment o f the solvents decreased.
