Application

MEK is mainly used in polyurethane resin, PU leather, and imitation leather. It is also used in bond, coating, lubricating oil dewaxing, printing ink, magnetic recording material etc.

MEK is an important fine chemical raw material.

Synthesis Methods

1.Indirectly Hydration of Sulfuric Acid

The mixed C4 fractions containing butanol were exposed to sulfuric acid. This reaction generates acid type sulfuric acid ester and netral type sulfuric acid ester. And then diluted with water, hydrolyzed to secondary butanol aqueous solution. Then dehydrated and enriched with the secondary butanol. Pure secondary butanol is catalyzed by nickel or zinc oxide and dehydrogenized. All finished.

2. Direct Hydration of N-butylene

This method is divided into two kinds. One is resin as a catalyst and the other is heteropoly acid as catalyst.

3. Secondary Butanol Dehydrogenation

This method is divided into gas phase method and liquid phase method. Gas phase method is used in dehydrogenation process mostly. In the process of dehydrogenation, secondary butanol was dehydrogenation and get butanone.

4. Ethylene gas phase oxidation

5. Sec-butylbenzene

Safety Information

Methyl Ethyl Ketone is a highly flammable and toxic liquid. Prolonged inhalation of its vapor can stimulate the eyes, nose, larynx and other mucous membranes and cause inflammation. The operation site should be kept well ventilated. Operators should wear masks and rubber gloves.

When skin or eye contact with 2- butanone, rinse with a lot of water immediately. The Severe person should be sent to the hospital for treatment.

Packing

165kgs/drum; 19MT/ISO tank.
