| titleOfInvention | Manufacturing method of 4,6-bis (substituted) phenyl azo resorcinol |
| abstract | Resorcinol and formula [1] (where R represents a halogen atom, C 1-5 alkyl, hydroxycarbonyl or C 1-5 alkoxy group, n represents an integer of 0 or 1-5, two or more R is the same as or different from each other, and X represents Cl, Br, OSO 3 H or OPO 3 H 2 ), and is represented by the formula [2] by reacting in an alkaline solution of the benzenediazonium salt represented by In the manufacturing method of 4,6-bisphenyl azo resorcinol; (A) A solution of the compound of formula [1] and a solution or suspension of an alkali metal or alkaline earth metal hydroxide are mixed to obtain an alkaline mixed solution, which contains the mixed solution and resorcinol and / or its alkali metal salt or alkaline earth metal salt. Or (b) a solution or suspension of a mixture of resorcinol and a mixture of 15 to 40 times the molar alkali metal hydroxide or alkaline earth metal hydroxide of resorcinol, and A method for producing a compound, characterized by mixing and reacting a solution of the compound of [1].n n n By the above method, the reaction volume can be reduced compared with the conventional method, and 4,6-bisphenylazo resorcinol can be obtained with high yield. |
