说明

一般描述

2-propanol is a clear and volatile liquid that is used in various industrial and commercial products for different purposes. It is used in paints, inks, fuels, disinfectants, and deicers. 2-propanol is useful in the production of waxes, animal and vegetable oils, and flavorings. It is also commonly found in household products like medications, colognes, perfumes, and toiletries. The most common source of 2-propanol exposure is rubbing alcohol (70%-90% isopropanol or ethanol).
