Labels industrial denatured alcohol

Completely Denatured Alcohol. Completely denatured alcohol (CD A) escapes the involved financial and administrative controls required of the other classifications of industrial ethanol. No tax is appHed, no bond is required, no permit is needed to enable a customer to purchase CD A. Requirements for records by both producer and user are minimal. These simplified regulations are possible because CDA is denatured with substances that render it totally unfit for beverage purposes. It is also unsuitable where odor is objectionable. CDA and products made from it are, however, governed by special labeling requirements of the BATE. Repackaging of completely denatured alcohol is permitted as long as labeling requirements are met. 

On the shelves of drugstores you can find bottles of ethanol labeled denatured alcohol. Denatured alcohol is ethanol to which small amounts of noxious materials such as aviation gasoline or other organic solvents have been added. Ethanol is denatured in order to make it unfit to drink. Because of their polar hydroxyl groups, alcohols make good solvents for other polar organic substances. For example, methanol, the smallest alcohol, is a common industrial solvent found in some paint strippers, and 2-butanol is found in some stains and varnishes, as shown in Figure 23-5. Perform the CHEMLAB at the end of this chapter to learn about some other properties of small-chain alcohols. 

Some commercial solvents, such as hexane, xylene, and ethyl alcohol, have minor components that can interfere with their effective use in a laboratory or industry. For example, denatured ethyl alcohol has purposely been contaminated with small amounts of poisonous organic liquids in order to deter someone from using it to make alcoholic drinks. Hexane and xylene are often labeled as the plural (hexanes and xylenes) to indicate that they are actually mixtures of isomers. In this experiment, the minor components of one or more of these solvents will be identified.
