What is Denatured Ethanol?
Denatured ethanol, also known as denatured alcohol, is ethanol (ethyl alcohol) that has been rendered unfit for human consumption by the addition of denaturants. Denaturants are typically chemicals that make the ethanol taste bad or have toxic effects, and they are added to discourage people from drinking the substance.
The denaturation process is done to avoid the high taxes and regulations associated with beverage alcohol, as denatured ethanol is intended for industrial, pharmaceutical, or cosmetic uses rather than for consumption. Common denaturants include toluene, heptane, methanol, isopropyl alcohol, acetone, and other chemicals.
Denatured ethanol is widely used in various industries, such as in the production of paints, solvents, cleaning products, and as a fuel for alcohol burners.
Why is Ethanol Denatured?
Ethanol is denatured, or rendered undrinkable, for several reasons:
Tax Purposes: Denaturing ethanol allows for the imposition of lower taxes on industrial or non-beverage alcohol compared to potable alcohol. Governments often place higher excise taxes on alcohol intended for human consumption.
Regulatory Compliance: Denaturing ethanol is a regulatory requirement to discourage the illegal diversion of tax-free industrial alcohol for beverage use. The addition of denaturants makes it unpalatable and unsafe for consumption.
Public Safety: Making ethanol undrinkable helps prevent accidental or intentional ingestion of industrial alcohol, which can be toxic. Denaturing agents are chosen to deter people from attempting to use denatured alcohol as a substitute for beverage alcohol.
Industrial Use: Denatured ethanol is widely used in various industries, including pharmaceuticals, cosmetics, and manufacturing. It serves as a solvent, fuel, or raw material in these applications.
Common denaturants include substances like heptane, toluene, methanol, isopropanol, and various chemicals that make the alcohol unsuitable for human consumption while maintaining its usability in industrial processes. The specific denaturing formulations, such as CDA 12-A mentioned earlier, are defined by regulatory agencies to ensure compliance with safety and tax regulations.
What is denatured ethanol used for?
Denatured ethanol is used for various industrial and commercial purposes where the alcohol is needed for its properties but should not be consumed. Here are some common applications:
Industrial Solvent: Denatured ethanol is widely used as a solvent in industries such as pharmaceuticals, cosmetics, and manufacturing. It is effective in dissolving a variety of substances.
Cleaning Agent: Due to its solvent properties, denatured ethanol is used as a cleaning agent for surfaces, equipment, and machinery in industrial and commercial settings.
Fuel Additive: Denatured ethanol is sometimes used as a fuel additive, especially in the blending of gasoline. It can improve combustion efficiency and reduce emissions.
Paint and Coating Industry: It is used as a solvent in the formulation of paints, varnishes, and coatings.
Pharmaceuticals: Denatured ethanol is used in the pharmaceutical industry for various purposes, including the extraction of medicinal compounds.
Laboratory Use: In laboratories, denatured ethanol is often used for tasks like sterilization and as a solvent for experiments.
Inks and Dyes: It is employed in the production of inks and dyes due to its ability to dissolve pigments.
Adhesives and Sealants: Denatured ethanol is used in the formulation of adhesives and sealants.
Window Cleaning: It is used in commercial window cleaning solutions.
Automotive Industry: In the automotive industry, denatured ethanol is used for cleaning and degreasing.
What can be used to denature ethanol?
Here are examples of common Completely Denatured Alcohol (CDA) formulations used to denature ethanol:
CDA 12-A
To every 100 gallons of alcohol, add either:
Five gallons of n-heptane
or 5 gallons of toluene.
CDA-19
To every 100 gallons of ethyl alcohol (not less than 160 proof), add:
4.0 gallons of either methyl isobutyl ketone, mixed isomers of nitro propane, or methyln-butyl ketone
1.0 gallon of either kerosene, deodorized kerosene, gasoline, unleaded gasoline, rubber hydrocarbon solvent, or heptane.
CDA-20
To every 100 gallons of ethyl alcohol (not less than 195 proof), add a total of:
2.0 gallons of either unleaded gasoline, rubber hydrocarbon solvent, kerosene, or deodorized kerosene, or any combination of these.
What does CDA mean?
Completely Denatured Alcohol (CDA) is a type of denatured alcohol that has been rendered unfit for human consumption by the addition of denaturing agents. Denatured alcohol is ethanol (ethyl alcohol) that has been intentionally adulterated to make it toxic, foul-tasting, or otherwise undrinkable. This denaturing process is done to exempt the alcohol from excise duty and other taxes, as it's not intended for use in beverages.
The denaturing agents used in CDA can vary, but they often include chemicals such as methanol, isopropanol, or other substances that make the alcohol unpalatable and potentially harmful if ingested. The specific formulation of denatured alcohol may be regulated by government authorities to ensure it meets safety standards and legal requirements.
CDA is commonly used in industrial applications, as a solvent, fuel, or as a cleaning agent. It's important to note that due to the addition of denaturing agents, CDA should not be used for purposes that involve contact with the human body or ingestion. Safety precautions, including proper ventilation, should be followed when working with denatured alcohol.
What is CDA 12A?
CDA 12-A is a formulation specified by the Alcohol and Tobacco Tax and Trade Bureau (TTB) for Completely Denatured Alcohol (CDA). The formula is defined under §21.26 as Formula No. 12-A. The composition of CDA 12-A is as follows:
For every 100 gallons of alcohol, add either:
5 gallons of n-heptane
or 5 gallons of toluene.
This denaturing process renders the ethanol unfit for consumption while meeting regulatory requirements for various industrial applications. CDA formulations, including CDA 12-A, are used to denature ethanol for purposes such as industrial solvents, cleaning agents, and manufacturing processes.
Can you remove Toluene from CDA 12A?
When toluene is added to ethanol it creates an azeotrope between the ethanol and n-heptane. An azeotrope is defined as a mixture of two liquids that have a constant boiling point and composition through distillation. This azeotrope results in the ethanol and n-heptane evaporating at the same temperature, making it extremely difficult to separate the two through distillation. While these azeotropic solvents are still easily recovered from a botanical extract at a relatively low boiling point around 78C/173F using a rotary evaporator or falling film evaporator, it is near impossible to separate the two via distillation.
What is an Azeotrope?
An azeotrope is a mixture characterized by having identical concentrations in both its vapor and liquid phases. This stands in contrast to ideal solutions, where one component is usually more volatile than the other, allowing for separation through distillation. When an azeotrope forms, the concentrations in both phases remain the same, hindering separation through traditional distillation methods.
Azeotropes consist of a blend of at least two different liquids, and this mixture can exhibit either a higher or lower boiling point than either of its individual components. Azeotropes become relevant when certain liquid fractions resist alteration through distillation processes. In typical mixtures, components can be extracted using Fractional Distillation, a process involving repeated distillation stages. The more volatile component vaporizes and is collected separately, while the less volatile component remains in the distillation container, resulting in two distinct, pure solutions.
