First, clean the surface with water and detergent. Ethanol is oxidized in the liver to acetaldehyde: The acetaldehyde is in turn oxidized to acetic acid (HC2H3O2), a normal constituent of cells, which is then oxidized to carbon dioxide and water. Here is an example that occurs in the Krebs cycle: fumarate is hydrated to form malate. 1996. In a similar manner, isopropyl alcohol is produced by the addition of water to propene (propylene). All the chemical needs is … ‰For 90% isopropyl alcohol, mix 1 part isopropyl alcohol to 2 parts water (this makes a 30% solution). > The solubility of an alcohol in water is a competition between two parts of the molecule: the polar "OH" group and the nonpolar hydrocarbon portion.
