Denatured alcohol and methyl hydrate are often compared as they are both used as solvents and fuels. Denatured alcohol is ethanol that has been made poisonous through the addition of various adulterants. The main additive is usually methanol, which is another name for methyl hydrate. However, other additives may be used, including gasoline, methyl ethyl ketone, ethyl acetate, and butyl acetate. Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. It is also used for cleaning and removing pencil marks. Methyl hydrate, on the other hand, is a highly poisonous form of alcohol that is quite toxic and readily absorbed through the skin. It is a more aggressive solvent than denatured alcohol and is used for cleaning and woodworking.

Denatured alcohol is ethanol with additives to make it poisonous, undrinkable, and unpalatable
Denatured alcohol is ethanol with additives that make it poisonous, undrinkable, and unpalatable. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; denatonium makes it bitter. Denatonium benzoate is added to give the substance an extremely bitter flavour. Substances such as pyridine are added to give the mixture an unpleasant odour, and agents such as syrup of ipecac may also be included to induce vomiting.
Denatured alcohol is ethanol that has been made poisonous (denatured) through the addition of various adulterants. Methanol (aka Methyl Hydrate) is the most common, but you may also see gasoline, methyl ethyl ketone, ethyl acetate, butyl acetate, and others. Methanol, like ethanol, will evaporate completely, making it a good cleaner. However, it is also quite toxic.
In many countries, denatured alcohol is traditionally dyed with methyl violet or a similar hue for safety reasons. In Central and Eastern Europe, this was mandatory during the communist era. In many countries, sales of alcoholic beverages are heavily taxed for revenue and public health policy purposes. To avoid requiring beverage taxes on alcohol that is not meant to be consumed, the alcohol is usually "denatured", or treated with added chemicals to make it unpalatable.
Methyl Hydrate is a synonym for methanol, and denatured alcohol is ethanol with a small amount (typically <5%) of natural gasoline distillate added to render it undrinkable. Methanol is a more aggressive solvent but also quite toxic. It is absorbable through the skin.

Methyl hydrate is a synonym for methanol, which is also known as methyl alcohol or wood alcohol
Denatured alcohol is often used as a substitute for methyl hydrate. However, it is important to note that they are not the same thing. While methanol is a more aggressive solvent, it is also quite toxic and can be absorbed through the skin. It is also highly flammable and can cause blindness, convulsions, and death if consumed.
On the other hand, ethanol is only moderately poisonous and not as easily absorbed through the skin. It is also less flammable than methanol. Denatured alcohol is commonly used to remove pencil marks and is often the preferred choice for certain applications due to its lower toxicity and flammability.
In summary, while methyl hydrate (methanol) and denatured alcohol share some similarities, they are not the same. Denatured alcohol is typically preferred due to its relatively safer properties compared to methanol. It is important to exercise caution when handling any of these substances and to follow the appropriate safety guidelines.

Both denatured alcohol and methyl hydrate are used for cleaning and woodworking
Denatured alcohol and methyl hydrate are both used for cleaning and woodworking. Denatured alcohol is ethanol that has been made poisonous by adding various adulterants, such as methanol, gasoline, methyl ethyl ketone, ethyl acetate, butyl acetate, and others. It is used as a solvent and as fuel for alcohol burners and camping stoves. It is also used for removing pencil marks and is often used by cyclists to clean their bike rotors.
Methyl hydrate, also known as methanol, methyl alcohol, or wood alcohol, is a more aggressive solvent than denatured alcohol and is quite toxic. It is the base of most kinds of denatured alcohol and is commonly used in Canada for Completely Denatured Alcohol (CDA). It is also used for cleaning and woodworking, with some people finding it more effective than isopropyl alcohol for dissolving shellac.
While both substances are used for similar purposes, there are some key differences. Denatured alcohol is typically a mixture of 90% ethanol and 10% methanol, along with other chemicals, while methyl hydrate is pure methanol. Methanol is more volatile, poisonous, and flammable than ethanol, and it is also more readily absorbed through the skin. Due to these factors, denatured alcohol is generally considered safer to use than methyl hydrate, especially for woodworking and cleaning applications.
It is important to note that both denatured alcohol and methyl hydrate can leave residues when used for cleaning or woodworking. For example, denatured alcohol can leave a white residue, while methyl hydrate can dry so fast that it leaves streaks. Additionally, some additives used in denatured alcohol, such as acetone, may not be suitable for certain surfaces, such as PCBs. Therefore, it is crucial to consider the specific application and take appropriate safety precautions when using either of these substances.

Denatured alcohol is sometimes consumed as a surrogate alcohol, which can be dangerous
Denatured alcohol is ethanol that has been made unfit for human consumption through the addition of various adulterants or denaturants. This process is called denaturing, and it is done to exempt the alcohol from beverage alcohol taxation. Denatured alcohol is also used as a solvent and as fuel for alcohol burners and camping stoves.
Methyl hydrate, also known as methanol, is the base of most kinds of denatured alcohol. It is added to ethanol to make it poisonous and is the most common denaturant. Other denaturants include gasoline, methyl ethyl ketone, ethyl acetate, butyl acetate, and others.
Despite its poisonous content, denatured alcohol is sometimes consumed as a surrogate alcohol. Surrogate alcohol is a term for any substance containing ethanol or other alcohols that are intentionally consumed by humans but are not meant for human consumption. Consumption of such substances carries extreme health risks, including acute poisoning from substances such as methanol, which can lead to blindness, convulsions, and death. In December 2016, 78 people died from drinking surrogate alcohol, poisoned with methanol, in the Russian city of Irkutsk.
The consumption of denatured alcohol as a surrogate alcohol can be dangerous due to the presence of methanol and other toxic substances. Methanol is highly poisonous and is readily absorbed through the skin, making it extremely harmful to those who consume it. To help prevent accidental consumption, denatonium is often added to give the substance an extremely bitter flavor, and pyridine is added to give it an unpleasant odor.

Methyl hydrate evaporates faster than denatured alcohol
Methyl hydrate, also known as methanol, is the base of most kinds of denatured alcohol. Denatured alcohol is ethanol that has been made poisonous (denatured) through the addition of various adulterants. It is also known as ethyl alcohol, grain alcohol, or simply alcohol.
While both methyl hydrate and denatured alcohol are used for similar purposes, such as cleaning and woodworking, there are some key differences between the two. One of the main differences is that methyl hydrate evaporates faster than denatured alcohol. This is because methanol, the main component of methyl hydrate, has a lower boiling point than ethanol, the main component of denatured alcohol.
Methyl hydrate is highly flammable and quite toxic, making it a more aggressive solvent than denatured alcohol. It is also more readily absorbed through the skin, so it is important to wear gloves and take other precautions when using it. Consuming methyl hydrate can lead to serious health issues, including blindness, convulsions, and even death.
Denatured alcohol, on the other hand, is only moderately poisonous and not as easily absorbed through the skin. It is often used as a solvent and as fuel for alcohol burners and camping stoves. To make it unappealing for recreational consumption, denatured alcohol is also made to taste bad and smell foul.
In summary, while both methyl hydrate and denatured alcohol have their own unique properties, methyl hydrate evaporates faster than denatured alcohol due to the lower boiling point of methanol compared to ethanol. It is important to exercise caution when using either of these substances and to follow the appropriate safety guidelines.
