Difference between Ethanol and Methanol

Ethanol and methanol are two alcohols that have different properties. Ethanol is commonly used as a fuel additive and in alcoholic beverages, while methanol is toxic. Let’s take a closer look at the differences between these two alcohols.

What is Ethanol?

Ethanol is a type of fuel that is produced from various agricultural crops, such as corn and sugar cane. This highly flammable liquid fuel is commonly used in cars, as it has a high energy content and burns relatively cleanly. Ethanol can also be chemically modified to produce other types of fuels, such as methanol or butanol, which are often used in industrial settings. Overall, ethanol is an important and versatile fuel that plays an important role in modern society.

What is Methanol?

Methanol, also known as wood alcohol, is a colorless and flammable liquid chemical compound. It is typically produced through a chemical reaction between carbon monoxide and hydrogen gas, and it can be used as an industrial solvent or fuel source. Methanol is sometimes used as a building block in the creation of other chemicals like formaldehyde and chloroform, although it can also be found naturally in small amounts in certain foods like berries, cheese, wine, and shellfish. Because it is highly toxic in large quantities, methanol must be handled with care by anyone who works with it professionally. Still, despite its dangers when not properly controlled, the wide variety of uses for methanol make this compound an important part of many industries today.

Difference between Ethanol and Methanol

  • There are many different types of biofuels, each with its own unique properties and benefits. The two most prominent biofuels are ethanol and methanol, which are often confused due to the similarities in their chemical structure. While these two fuels have some key differences, both have shown a great deal of potential for use as an alternative to traditional fossil fuels.
  • Ethanol is an alcohol-based fuel made from fermented crops like corn or sugarcane. Unlike methanol, which is produced through a simple process known as steam reforming, ethanol is formed through a far more complex process that involves several steps and enzymatic reactions. Despite this added complexity, ethanol has some key advantages over methanol when it comes to performance and sustainability. For instance, ethanol tends to be less chemically reactive than methanol, making it less likely to damage engines or other components in vehicles or machinery. Additionally, because it can be made from crops like corn or sugarcane that can also be used for food production, ethanol can offer more environmentally-friendly benefits compared to other biofuel sources like petroleum.
  • However, even though ethanol has many desirable qualities when compared to methanol, there are some drawbacks that must be considered as


Although both ethanol and methanol are alcohols, they have different chemical structures. Ethanol is a small molecule that can easily cross the blood-brain barrier, while methanol is a larger molecule that cannot cross this barrier. This difference is why ethanol is intoxicating and methanol is not. Methanol poisoning can cause blindness and death, while ethanol intoxication generally does not have such severe consequences.
