HOMOPHTHALONITRILE Usage And Synthesis

New Engineering Thermosets

Homophthalonitrile are a relative new class of commercial high performance engineering thermosets. They exhibit very high thermal and oxidative stability, and outstanding high-temperature properties. Infact, Homophthalonitriles have one of the highest decomposition temperature of all organic thermoset polymers which can approach 500℃ in air. Both, the high thermal stability and the high char yield contribute to the outstanding high-temperature performance. However, homophthalonitriles have also some major limitations and shortcomings. For example, they are very expensive and difficult to process, relative to conventional thermoset resins.

Chemical Properties

beige to brown powder and/or chunks

Uses

2-Cyanophenylacetonitrile may be used in the synthesis of 2, 5-diphenylpyrazine.

General Description

2-Cyanophenylacetonitrile undergoes carbocyclization reaction with bromoacrylonitriles to give naphthylamine.
