623-26-7, name is Terephthalonitrile, belongs to nitriles-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: Terephthalonitrile
Example 38 Terephthalonitrile (12.8 g), hydrogen chloride gas (2.24 NL), and ethanol (72.5 g) were placed in a glass autoclave, and the mixture was allowed to react at 130 C. for six hours. The reaction mixture was cooled, and water (9 g) was added thereto. Gas chromatographic analysis revealed that ethyl p-cyanobenzoate had been produced at a yield of 30% and a selectivity of 96%.
The synthetic route of 623-26-7 has been constantly updated, and we look forward to future research findings.
