Evaluation of two viral inactivation methods for the preparation of safer factor VIII and factor IX concentrates
(Blackwell Publishing: Transfusion, 1985-11)We report here the results of our evaluation of two procedures to eliminate viruses in factor VIII and factor IX coagulation factor concentrates. Both procedures were equally effective in the in vitro destruction of marker ... -
Palladium/hydrogen catalyzed alcoholysis of benzylsilanes
(Elsevier: Journal of Organometallic Chemistry, 1976)Certain benzylsilanes are converted to methoxy or ethoxysilanes and toluene when treated with methanol or ethanol in the presence of hydrogen and catalytic amounts of palladium on charcoal. The reaction is promoted by a ... -
