2-Ethylanthraquinone Chemical Properties,Uses,Production

Description

2-Ethylanthraquinone is an organic compound that is a derivative of anthraquinone. It is commonly used in the industrial production of hydrogen peroxide (H2O2) due to its high selectivity. Another major application is the production of dyes2. It can also be used as a photo-initiator of crosslinking or degradation of polyethylene3.

Chemical Properties

white or yellowish crystals or powder

Uses

2-Ethylanthraquinone can be used as a photoinitiator of crosslinking or degradation of polyethylene. It is used to produce hydrogen peroxide by hydrogenation with the help of Pd/polyaniline as the catalysts.

Uses

Synthesis, especially of hydrogen peroxide.

Flammability and Explosibility

Non flammable

Synthesis

2-(4-ETHYLBENZOYL)BENZOIC ACID

1151-14-0

2-Ethylanthraquinone

84-51-5

General procedure for the synthesis of 2-ethylanthraquinone from 2-(4-ethylbenzoyl)benzoic acid: (2) 2-(4-ethylbenzoyl)benzoic acid prepared as described above and concentrated sulfuric acid were sequentially passed through a piping system comprising a T-type mixer, a reactor A, a Y-type mixer, a reactor B and a separator. In this system, 2-(4-ethylbenzoyl)benzoic acid enters the T-mixer at 180° C., while concentrated sulfuric acid enters the T-mixer at 50° C. The mass-volume ratio of the two is 1 g:3 mL. The mixing temperature in the T-mixer is 50° C., and the residence time is 35 seconds. Subsequently, the mixture enters reactor A and is reacted at 120°C for 30 minutes. Next, it was passed through a Y-mixer at 40°C and finally into Reactor B where the reaction was completed at 50°C to produce 2-ethyl anthraquinone in 95.5% yield.
