Disinfection by Alcohol

Environmental Surface Cleaning and Disinfection: Effects of Alcohol Concentration

I nfection prevention programs for health care facilities include environmental surface cleaning and disinfection as fundamental components. The use of chemical disinfectants is warranted in certain instances because it is neither necessary nor possible to sterilize all contaminated items and surfaces after provision of patient care. The importance of environmental asepsis is evident as reporte...

Inhibition of human peripheral blood neutrophil respiratory burst by alcohol-based venipuncture site disinfection.

Ethanol inhibits the respiratory burst of neutrophils. Therefore, the effects of alcohol-based skin disinfection on oxygen metabolism in neutrophils were tested using 70% ethanol or an ethanol-isopropanol-n-propanol mixture. Neutrophil respiratory burst activity as assessed fluorometrically by oxidation of 2', 7'-dichlorofluorescein diacetate increased at 10 min after disinfection with 70% etha...

Zeolite catalyzed alkylation of toluene by alcohol

Vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using N2 carrier over a series of surface modified andunmodified ZSM-5 (Si/Al= 60-170) loaded with H3PO4, differing in the external surface treatment of the zeolites.The feed molar ratios of toluene/methanol and toluene/2-propanol were...

Disinfection By-products: A Question of Balance

By all accounts, disinfection of drinking water is one of the major public health triumphs of the 20th century. No human endeavor, however, is without risk; more than 30 years ago it was determined that chlori­ nation of water resulted in formation of disinfection by­products (DBPs). Several of these, such as the trihalomethanes (THMs) and haloacetic acids (HAAs), were subsequently observed to ...
