Acetone at Best Price, Supplier Manufacturer Kolkata India

Acetone is a manufactured chemical that is also foundnaturally in the environment. It is a colorless liquid with a
distinct smell and taste. It evaporates easily, is flammable,and dissolves in water. It is also called dimethyl ketone,
2-propanone, and beta-ketopropane.Acetone is used to make plastic, fibers, drugs, and otherchemicals. It is also used to dissolve other substances.It occurs naturally in plants, trees, volcanic gases, forestfires, and as a product of the breakdown of body fat. It ispresent in vehicle exhaust, tobacco smoke, and landfill sites.Industrial processes contribute more acetone to the environment than natural processes. 

What happens to acetone when it enters theenvironment?

A large percentage (97%) of the acetone released duringits manufacture or use goes into the air.

 In air, about one-half of the total amount breaks downfrom sunlight or other chemicals every 22 days.

 It moves from the atmosphere into the water and soil byrain and snow. It also moves quickly from soil and water
back to air. 

 Acetone doesn’t bind to soil or build up in animals. It’s broken down by microorganisms in soil and water.
 It can move into groundwater from spills or landfills.Acetone is broken down in water and soil, but the time
required for this to happen varies.

Uses

About a third of the world's acetone is used as a solvent, and a quarter is consumed as acetone cyanohydrin, a precursor to methyl methacrylate.

Solvent

Acetone is a good solvent for many plastics and some synthetic fibers. It is used for thinning polyester resin, cleaning tools used with it, and dissolving two-part epoxies and superglue before they harden. It is used as one of the volatile components of some paints and varnishes. As a heavy-duty degreaser, it is useful in the preparation of metal prior to painting. It is also useful for high reliability soldering applications to remove rosin flux after soldering is complete; this helps to prevent the rusty bolt effect.

Acetone is used as a solvent by the pharmaceutical industry and as a denaturant in denatured alcohol. Acetone is also present as an excipient in some pharmaceutical drugs.

Although itself flammable, acetone is used extensively as a solvent for the safe transportation and storage of acetylene, which cannot be safely pressurized as a pure compound. Vessels containing a porous material are first filled with acetone followed by acetylene, which dissolves into the acetone. One liter of acetone can dissolve around 250 liters of acetylene at a pressure of 10 bar.

Laboratory

In the laboratory, acetone is used as a polar, aprotic solvent in a variety of organic reactions, such as SN2 reactions. The use of acetone solvent is critical for the Jones oxidation. It does not form an azeotrope with water (see azeotrope (data)). It is a common solvent for rinsing laboratory glassware because of its low cost and volatility. Despite its common use as a supposed drying agent, it is not effective except by bulk displacement and dilution. Acetone can be cooled with dry ice to −78 °C without freezing; acetone/dry ice baths are commonly used to conduct reactions at low temperatures. Acetone is fluorescent under ultraviolet light, and its vapor can be used as a fluorescent tracer in fluid flow experiments.
