STUDY OF PHYSICO-CHEMICAL PROPERTIES OF ETHYL AND ISOPROPYL ALCOHOL
Keywords:
ethyl alcohol, isopropyl alcohol, freezing point, density, viscosity, corrosion rate, corrosion inhibitors, carbon steelAbstract
As a result of studying the physical properties of low-freezing solutions, it was determined that a 35-40% solution of ethyl alcohol and a 40-45% solution of isopropyl alcohol can be used to develop an environmentally friendly windshield washer fluid for the climatic conditions of Kyrgyzstan. Corrosion studies of carbon steel, brass, copper and aluminum have shown that carbon steel has the highest corrosion rate and it increases with increasing test duration. The study of the dependence of the corrosion rate of carbon steel on the concentration of alcohol showed that the corrosion rate of steel in water-alcohol solutions decreases as the concentration of alcohol increases, and after reaching 75–80%, it sharply decreases.
