Solid state reaction between 8-hydroxyquinoline and p-nitrobenzoic acid

摘要

8-Hydroxyquinoline reacts with p-nitrobenzoic acid in solid state forming 1:1 molecular complex. In solid state the diffusion of 8-hydroxyquinoline occurs towards p-nitrobenzoic acid and the process of diffusion is not vapour phase dominated process. Micro structural studies have indicated that reaction during solid state may be nucleation controlled process. Reaction products obtained from solution and solid state reaction are identical and their is a hydrogen bonding between the components in the reaction product.
