Diisopropylbenzene is an important organic chemical raw material, widely used in medicine, pesticides, spices, dyes and other fields. This article will detail the properties and uses of dicumyl.

1. the nature of dicumyl

dicumyl is a colorless transparent liquid with aromatic odor. Its molecular formula is C12H18 and its molecular weight is 162.27. Diisopropylbenzene has a melting point of -48°C, a boiling point of 217°C and a density of 0.86g/cm3. It is insoluble in water, but can be miscible with alcohol, ether, benzene and other organic solvents. Diisopropylbenzene has the advantages of good stability, low toxicity, not easy to ignite and explode, so it is widely used in chemical production.

2. the use of dicumyl

1. pharmaceutical intermediates

dicumyl is an important pharmaceutical intermediates, can be used for the synthesis of a variety of drugs. For example, it can be used to produce the anti-tuberculosis drug isoniazid, the anti-tumor drug cyclophosphamide, etc. In addition, diisopropylbenzene can also be used to produce some antibacterial drugs and anti-inflammatory drugs.

2. pesticide intermediates

dicumyl is also a common pesticide intermediates, can be used to produce a variety of pesticides, fungicides and herbicides. For example, it can be used to produce the insecticide trichlorfon, the fungicide carbendazim, etc.

3. Perfume and Dye Intermediates

Dicumyl can also be used to produce perfume and dye intermediates. For example, it can be used to produce the fragrance vanillin, the dye acid red, etc.

4.

in other fields In addition to the above fields, dicumyl can also be used to produce some special solvents, plasticizers, etc. In addition, it can also be used to produce monomers for some polymer materials.

3. diisopropylbenzene production method

diisopropylbenzene production method mainly has two kinds: one is obtained by benzene and propylene alkylation reaction, the other is obtained by isopropylbenzene and propylene alkylation reaction. Both methods require the use of a catalyst and the reaction is carried out at a certain temperature and pressure. The obtained dicumyl needs to be refined and separated to meet different requirements.

In conclusion, diisopropylbenzene is an important organic chemical raw material and has broad application prospects. In the future development, with the progress of science and technology and the expansion of application fields, the use of diisopropylbenzene will be more extensive.
