Ethanol and other alcohols were the original fuel of choice for automobiles. The growth of petroleum companies in the late 1800's influences a change to fossil fuel.
The present labeling of ethanol as a "green" fuel is fairly recent as a branding effort. Most studies indicate that it has severe drawbacks as far as energy content and overall carbon footprint.

When you boil a leaf in ethanol, the ethanol will extract the pigments and other compounds from the leaf. The chlorophyll will dissolve in the ethanol, causing the leaf to lose its green color and appear pale. The ethanol will take on the color of the extracted pigments, turning it into a green solution.
Yes, ethanol can become a solid when it reaches its freezing point of -114.1°C (-173.4°F). At this temperature, ethanol transitions from a liquid to a solid state.
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour) wash with water to rehydrate and soften the leaf
Ethanol can extract chlorophyll from the leaf, causing it to lose its green color and appear white. Chlorophyll is the pigment responsible for the green color in plants, and when it is removed by ethanol, the underlying white color of the leaf becomes visible.
Soaking green leaves in ethanol helps remove the green pigment chlorophyll and other pigments, leaving behind a colorless solution. This process is often used in the laboratory to extract plant pigments for further analysis or to study the composition of leaves. Ethanol is able to break down the cell membrane and dissolve the pigments, allowing them to be separated from the leaf tissue.
Chlorophyll and other pigments in the chloroplasts were dissolved in the ethanol during the extraction process, leading to the green color of the solution.
Ethanol has a boiling point of 173.1°F (78.37°C) at standard atmospheric pressure. At this temperature, ethanol becomes volatile and can vaporize.
Yes. Bactranol or Bacterial Transformation ethanol can be used to convert cellulose directly into ethanol using complex marine bacterium that can convert waste green material into ethanol. This is a method of Ceetol production. Ceetol is the abbreviation for Cellulosic Ethanol. (CeEtOl - Cellulosic Ethanol OL - denotes Alcohol)
It numbs the pain but the bad part of it is that it numbs the entire area that the ethanol was applied to. The numbness does not go away. Afraid that it will become perminant. Swelling of the area where the ethanol was applied to. Texture changes. scary....
Yes, as ethanol is pure alcohol 5% of water would not be enough to get a rid of the alcohol.
When ethanol is mixed with fat, the color may become cloudy or opaque, but there would not be a distinct color change as ethanol and fat are both colorless. The appearance may depend on the concentration and types of fat and ethanol being mixed.
