Document Type and Number:
WIPO Patent Application WO/2017/067098
Kind Code:
A1
Abstract:
A preparation method for an aryl-substituted p-phenylenediamine substance is provided. The structural formula of the aryl-substituted p-phenylenediamine substance is as follows, wherein R'' is phenyl or o-methylphenyl, and R' and R'' are identical or different. The preparation method comprises: raw material A and raw material B reacting under the action of a hydrogen acceptor and a catalyst to form an aryl-substituted p-phenylenediamine substance. The structural formula of raw material A is as follows; raw material B is cyclohexanone and/or o-methylcyclohexanone; and the hydrogen acceptor is a hydrogen acceptor that can be hydroconverted into raw material B. The preparation method uses inexpensive and readily available raw materials, and does not need a large amount of water in the post-treatment of the reaction. The reaction has mild conditions and does not corrode reaction devices. Therefore, the preparation method is environmentally friendly, has less pollution and can help gain more economic benefit.
