Can steam distillation be done using a mixture of ethanol and water why and why not?

I hesitate to say that it literally can't be done, but ethanol dissolves things that water doesn't and the whole point of steam distillation is that the thing you're steam distilling needs to not be very soluble in water, so at best there's no real benefit from adding ethanol and at worst you can't separate your desired product out of the ethanol/water mix.
If you're not trying to separate it out, then ... you're not really doing a "steam distillation", you're doing an extraction. Gin, for example, is made by allowing the vapors from an ordinary distillation of ethanol/water (to increase ethanol content) to pass over/through substances like juniper berries to pick up some of the essential oils from these and give the resultant product flavor.

Can steam distillation of ethanol be done using a mixture of ethanol and water?
I dont think so because ethanol, containing an OH group is readily soluble in water.
How do you separate Ethanol and water?
Ethanol and water can be separated by fractional distillation. Fractional distillation separates liquid mixtures with different boiling points. Ethanol boils at a lower temperature than water. However, it forms a boiling azeotrope with water (azeotropes occur when solvent mixtures boil at a lower temperature than the component solvents). The azeotrope boils at 77.85 degrees, whereas pure ethanol boils at 78.4 degrees. The azeotrope is 96% ethanol and 4% water by volume. This is the maximum concentration of ethanol that can be achieved by simple distillation. Other methods of separating ethanol from water include using salts to make the water and ethanol phase-separate, using molecular sieves, using additives to change the azeotropic mixture, or distilling dry ethanol from wet ethanol that has been treated with a water-reactive metal, leaving behind the solid metal hydroxide.
Is it possible to have an absolute alcohol from ninety percent ethanol using fractional distillation?
Of course not!!! NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
How do you make ethanol gas?
Ethanol can be produced by:Anaerobic fermentation of natural sugar (beets, cane, starch) done by yeastPetrochemically by acid catalized reaction of ethene with water
What are the concerns of using ethanol as a fuel?
Ethanol has many considerations as far as its use as an automotive fuel.\: # On the plus side it is a liquid and easily handled in the present transportation and delivery systems. # On the negative side: * Ethanol from food crops removes food from the system * It requires more energy to produce ethanol than the automobile gets out of the ethanol (Crops require fertilization and fertilizers are made using hydrocarbons, ethanol is made by fermaentation, the fermentation products require distillation, the ethanol is a less efficient fuel than gasoline) * Ethanol combustion creates tail pipe emissions of aldehydes and ketones at levels not present in hydrocarbon fuelled autos * There is not enough land to produce enough ethanol fuel while maintaining food production * Ethanol from waste cellulose is not being pursued asa production route

How do you collect ethanol if it is in a mixture with water?
Distillation. Ethanol can be easily collected from water using distillation up to 97% purity.
What is the best fractionating column for ethanol distillation using lab glass?
distillation column
What would be left in the flask when separating alcohol from water using fractional distillation?
In order to separate a mixture of alcohol (ethanol) and water, use a process known as fractional distillation. This technique relies on the principle that the compounds in the mixture have different boiling points. Since ethanol boils at a lower temperature (78.5 degrees C) than water, the alcohol vaporizes while the water remains a liquid. At some point, it will become an azeotropic mixture where the vapor has the same composition as the liquid. A good distillation column will produce an azeotropic mixture of 95 percent alcohol and 5 percent water. This ratio represents the most pure form of ethanol possible with distillation and is widely accepted as an industry standard.

How are ethanol and beer separated?
well i still think by using the method called fractinal distillation

What is to purify by boiling and condensing?
This is known as a distillation. Ethanol and water can be separated using this process because their boiling points are different which allows them to be "boiled off" at different temperatures.
Can you separate water and alcohol?
Previous answer: "You can use distillation to separate alcohol and water due to their different boiling points."Not quite. You can partially separate alcohol (ethanol) and water due to their different boiling points. Water and ethanol form what is called an azeotrope, meaning that at a certain concentration of ethanol (somewhere around 94-96% I think, not sure) you can not separate the water and ethanol to any greater extent through distillation. It is still possible to get 100% ethanol, but this has to be acheived either through exhaustively exact synthesis or using a water sequestration or drying agent on a water ethanol mixture and re-purifying the ethanol by whatever process is relevant.to separate this liquid -liquid mixture we must use-fractional distillationbecause alcohol for eg. methyl alcohol boils @ 64.7 C& water @ 100 C
Is alcohol a mixture compound or solutions?
Solutions are a specific type of mixture. Rubbing alcohol is usually 70% or so 2-propanol with the remainder being water. This is technically both a solution and a mixture.
What is the problem with using a simple distillation apparatus a glass tube?
The problem with distillation is how to turn all of the hot vapour back into liquid. A simple distillation experiment using just a glass tube as a condenser, rather than a Liebig one, loses most of the steam.
