All about ethanol, ethanol fuel

Density ethanol

Ethanol has a density of 0.789 g/ml at 20 degree Celsius. The density of ethanol is determined by the mass per unit volume. The mass always remains constant. So the only thing that would change the density of ethanol would be its volume.

The volume of ethanol is affected by changes in pressure and temperature. That in turn changes the density of ethanol. There is a method that can help you to calculate the exact density of ethanol. Place a graduated cylinder on a scale. Pour the amount of ethanol that you want to measure into the graduated cylinder. Then you read and record the volume from the cylinder. Then read the mass from the scale. You can calculate the density of ethanol by simply dividing the volume calculated from cylinder by the mass calculated by the scale. It is a very easy procedure. In order to measure an accurate value of ethanol one must have a good alcohol monitoring system. This way you can get an exact reading of the water content and the concentration of ethanol. It is important that the water content is not too much. Then there is another type of density known as the energy density. It is the amount of energy per mass. The greater is the value of energy the more useful is the resource.

In comparison to methanol, ethanol has a greater energy density whereas gasoline has a much higher energy density than that of ethanol. The energy density of ethanol is 25 mega joules per kilogram (MJ/kg). The density of ethanol matters according to its uses. As a form of alcohol, the ethanol density varies significantly.

The market for ethanol is huge and the manufacturers cater to the different needs and requirements of consumers by producing different grades of ethanol with varying density. Density is a very important property. This is because the degree of ethanol density can determine whether it is fit for human consumption as alcohol or is to be used for other purposes such as fuel.

Pure ethanol is colorless and odorless. It is high in density. Due to the high density of pure ethanol, it is harmful as it can damage the human tissues thus, it should not be consumed by a human at any time. High density ethanol can be used for industrial purposes such as disinfectant, fuel and many others. It is considered as an industrial grade alcohol. On the other hand, there is ethanol of very low density. These can be found in alcoholic beverages and few medicines. This low density ethanol is safe for human consumption. But an important point to remember is that it should be consumed in moderation.

Although it is safe for consumption but excess of it can be harmful. For instance, excessive drinking of alcoholic beverages can damage the liver and also have various side effects till the time you reach old age. If you are suffering from diseases such as cancer etc. then ethanol based beverages should not be touched at all as it can aggravate the medical condition and can create complications.

Pregnant women are also not allowed to consume ethanol based alcoholic drinks as this can directly affect the fetus. In order to find out whether the ethanol is food grade or industrial grade alcohol, there are certain ways to determine the ethanol density. Manufacturers put the density of the ethanol on its label. So, this is why on the label of say a wine bottle you would find a lower density of ethanol whereas, in case of a disinfectant, the ethanol density will be much higher.
