| titleOfInvention | Process for producing nuclear-substituted salicylic acid and metal salts thereof |
| abstract | (57) [Summary] [Structure] General formula (1) (In the formula, R 1 and R 2 are each a tertiary butyl group, It is a tert-aryamyl group, a tersharyoctyl group, an isononyl group or an isododecyl group, and at least one of R 1 and R 2 is an isononyl group or an isododecyl group. ) Is substantially water-insoluble with respect to the alkali metal salt of the nucleus-substituted phenol (100 to 50 mol% of the alkali metal salt is a potassium salt and 0 to 50 mol% is a sodium salt). The general formula (2): wherein the Kolbeschmitt reaction is carried out using the solvent of (Wherein R 1 and R 2 are as defined above, and M Is a hydrogen atom or a metal atom, and n is a valence of M. ) A method for producing a nucleus-substituted salicylic acid or a metal salt thereof represented by [Effect] The reaction yield of a specific nucleus-substituted salicylic acid and its metal salt can be increased, and the purity can be improved up to an unpurified state, so that the developer for a pressure-sensitive recording sheet can be prepared. Can be used. |
