we use alcohol in its preparation to decrease solubility of ammonia in water so that it will react with copper to form complex and decrease solubility of complex will crystallize it out.
we use ethanol to decrease the solubility of ammonia in water,so that ammonia easily combines with copper in less polar environment now..in this way solubility is decreased and the complex i.e tetraammine copper 2 sulphate crystallizes out..

Well, to write it out is complex, but I will do my best: C18H36O2 + NaOH = alcohol + salt of the carboxylic acid (soap) The proper name for this process saponification, and the specific products can be determined via GC analysis or through your own tedious calculations.

Alcohol helps to prevent super saturation.
barium chloride reacts with a sulphate to produce barium sulphate which can be seen as a white precipitate and therefor identified.
as an emulsifying agent
2rch2oh + o2 -------> 2rcho + 2h2o
A tincture is an herbal preparation that is typically in alcohol. It is most commonly used for tonics.
The chemical reaction for the industrial preparation is:C2H4 + H2O = C2H5OH
This is a detergent. The alcohol that is ethoxylated determines the length of the nonpolar part of the molecule. One example of this type of detergent is Sodium laureth sulfate, or sodium lauryl ether sulfate (SLES).

Oximes are Compounds containing OH group linked to the nitrogen atom, as we know like dissolves like, so this compound containing OH can be easily dissolved in alcohol, the product will be soluble in alcohol and easy to seperate.\
Neutral grain spirits are rectified spirits made from grain. extra neutral alcohol is made from grains and used as for driniking and in industries. It is used for preparation of beaverages of pharmaceuticals etc.
