| titleOfInvention | Novel method for compounding naphtho-spirooxazine type photochromic compound |
| abstract | The invention belongs to the technical field of preparation and application of the spirooxazine type organic photochromic materials, in particular to a novel method for compounding naphtho-spirooxazine type photochromic compound. The method comprises the following steps: (1) mixing 2, 3, 3-trimethyl indole iodide and organic base, and stirring and heating the mixture to completely dissolve the mixture, (2) adding substitutional 2-hydroxyl naphthylamine, methylbenzene, oxidizing agent, activating agent and water-removing agent, (3) violently stirring and controlling appropriate temperature, tracking a reacting process by TLC, stopping the reaction until blue point phosphor dots disappear, conducting suction filtration while the temperature is high, cooling the mixture to be at indoor temperature, reducing pressure and removing solvent, obtaining brownish red oily liquid, conducting chromatographic column separation, conducting absolute ethyl alcohol recrystallization, and obtaining the naphtho-spirooxazine type photochromic compound. The novel method for compounding the naphtho-spirooxazine type photochromic compound has the advantages that reaction condition is gentle, operation is simple, product yield is high, and side reactions are few. |
