| abstract | PURPOSE: To obtain the titled substance useful as a raw material for a functional high polymer compound in high purity in high yield, by oxidizing a 2,6-bis(hydroxymethyl)phenol with MnO 2 . n CONSTITUTION: A compound shown by the formula I R is H, or 1W4C alkyl) is brought into contact with MnO 2 in a solvent such as chloroform, acetone, ether, etc. at about room temperature for several hours W several days, to give a compound shown by the formula II. Active MnO 2 obtained by thermal decomposition of manganese carbonate or manganese oxalate, or precipitation method from potassium permanganate and manganese sulfate, etc. is preferable as MnO 2 , and an amount of it used is 5W50 times as much as the compound shown by the formula I by weight. n EFFECT: After the reaction is over, the desired substance having practically sufficient purity is obtained simply by filtering the reaction solution to remove a Mn compound, followed by evaporating a solvent. n COPYRIGHT: (C)1985,JPO&Japio |
