| titleOfInvention | Production of bis(6-chloro-2-pyridyloxy) compound |
| abstract | PURPOSE: The reaction of 2,6-dichloropyridine with a dihydroxy compound such as hydroquinone is carried out in the presence of a base in an aprotic polar solvent to produce the title compound which is a starting substance of novel polyether resins in high yield and high purity through simple operations. n CONSTITUTION: Pyridine is chlorinated into 2,6-dichloropyridine and the product is allowed to react with a dihydroxy compound of HO-X-OH (X is given in the table) such as 2,2'-bis(4-hydroxyphenyl)propane in the presence of a base such as anhydrous potassium carbonate in an aprotic polar solvent such as 1,3-dimethyl-2-imidazolidinone, sulfolane to give bis(6-chloro-2-pyridyloxy) compounds. Since the product has active chlorine groups, it is useful as a starting substance for heat-resistant resins. n COPYRIGHT: (C)1988,JPO&Japio |
