There are actually a number of different ethanol properties that are of serious importance, and it should be known first off that there are both chemical and physical ethanol properties that need to be taken into account. For instance, the first thing that you need to know is that ethanol is a monohydric primary alcohol, and it melts at -117.3 C and boils at 78.5 C.
More Information on Ethanol Properties
As well, in regards to what you need to know about ethanol properties, another one of the most important factors in reference to ethanol properties is the fact that ethanol is miscible, in that it mixes without separation, with water in all proportions and it is separated from water only with difficulty.
Basically, any ethanol that is completely free of water is called absolute ethanol, and it is incredibly important to know that ethanol forms a constant boiling mixture, or azeotrope, with water that contains at least 95% ethanol and 5% water, and which boils at 78.15 C; since the actual boiling point of this binary azeotrope is below that of pure ethanol, then thus absolute ethanol cannot be obtained by simple distillation.
However, you should not feel as though there is no way around this; if benzene is added to 95% ethanol, for instance, a ternary azeotrope of benzene, ethanol, and water, with a boiling point of 64.9 C can then form, since the proportion of water to ethanol in this particular situation is greater than that in 95% ethanol, then the water is then able to be removed from the ethanol by adding benzene and distilling off this azeotrope.
Basically there are many different properties, all of which are highly relevant to the matter of ethanol overall, and all of which must be properly understood in order to gain any sort of actual realization on the issue of ethanol in general. Furthermore, ethanol is a rather complex subject, and because it is going to be even more popular within only years, it is thus incredibly important that everyone try to learn as much about it as they can before this happens.
In order to find out more information on ethanol, there are many different things that you can do, with the best choice being to simply read and research on it yourself; you can go to your local library, or even use the Internet from the comfort of your own home and browse through the multitude of information that is offered to you on there.
