How do you dry and distill acetone?

Acetone can be shaken with Drierite (25g/L) for several hours before it is decanted and distilled from fresh Drierite (10g/L) through an efficient column, maintaining atmospheric contact through a Drierite drying tube. The equilibrium water content is about 10-2M.

Is anhydrous acetone the same as pure acetone?

Anhydrous Acetone refers to a product that contains no water, so there is no water content in the Acetone. Our Acetone that we stock is 99.8\% Acetone with 0.2\% water content (as per last testing February 2019).

What is dry acetone used for?

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.

How do you dry acetone with molecular sieves?

Once acetone was no longer detected (smelled), the molecular sieves were transferred to an oven-safe container (metal or Pyrex) and placed into a 250°C oven for 24 hours. For fast drying, the ideal is to have the molecular sieves spread in a thin layer in a shallow container.

Is magnesium sulfate anhydrous?

Anhydrous magnesium sulfate is commonly used as a desiccant in organic synthesis owing to its affinity for water and compatibility with most organic compounds. Other inorganic sulfate salts such as sodium sulfate and calcium sulfate may be used in the same way.

What is acetone formula?

C3H6O
Acetone/Formula

Is 99\% acetone anhydrous?

The acetone you have (99.9 \%) may be pretty pure but is certainly not dry (anhydrous).

What is ACS grade acetone?

Reagent/ACS Grade – Reagent or ACS grade acetone is much purer than a technical grade, being a minimum of 95\% free of impurities. This grade of acetone can be used for a larger variety of products, and processes, but is not pure enough to be considered food grade.

Is anhydrous acetone a liquid?

It is a colorless, volatile, flammable liquid with a characteristic odor. Acetone is miscible with water and serves as an important solvent in its own right, in industry, home, and laboratory.

How do you make anhydrous DMF?

Dry DMF can be prepared by drying overnight over barium oxide or 4A molecular sieves, followed by decantation of the drying agent and vacuum distillation (~20 mmHg is a sufficient vacuum to lower the boiling point over DMF to a reasonable value). Dry DMF can be stored over 4A molecular sieves.

How do you activate molecular sieves?

They can be activated by passing hot dry gas through them. Usually the boiling point of water is sufficient if the gas is supplied very dry like distilled argon or nitrogen for most purposes and distilled neon or helium for extreme cases. A molecular sieve is a material with pores (very small holes) of uniform size.
