Absolute Alcohol

The company makes available high quality Absolute Alcohol. Absolute or anhydrous alcohol refers to ethanol with low water content. There are various grades of Absolute Alcohol, with maximum water contents ranging from 1% to ppm levels. Pure ethanol is classed as 200 proof in the USA, equivalent to 175 degrees proof in the UK system.
It can be produced commercially by two methods which include :

• Azeotropic distillation using entrainers (benzene, cyclopropane, cyclohexane, etc.
• Adsorption Method using molecular sieves as an adsorbing material, in which molecular sieves Dehydration Plants based on adsorption process is widely exercised.

In the process, water present in rectified spirit is adsorbed by molecular sieves under high temperature (above 150^oC) and high pressure (about 3 kg. /cm)
Grades Available :

• Pharmacy Grade : It is best quality of alcohol having minimum strength of 99.6% to 99.99% used under pharmaceutical industries for several medicines.
  
• Industrial Grade : Absolute alcohol (Industrial Grade) is not intended for human consumption. If azeotropic distillation is used to remove water, it will contain trace amounts of the material separation agent (e.g. benzene). Absolute ethanol is used as a solvent for laboratory and industrial applications because in case of rectified spirit, water will react with other chemicals, and as fuel alcohol. Spectroscopic ethanol is an absolute ethanol with a low absorbance in ultraviolet and visible light, fit for use as a solvent in ultraviolet-visible spectroscopy.

It is useful for fuels, perfumes etc. The largest single use of ethanol is as a motor fuel additive. More than any other major country, Brazil relies on ethanol as a motor fuel. Gasoline sold in Brazil contains at least 25% anhydrous ethanol.
