Reaction Conditions:
with thionyl chloride in N,N-dimethyl-formamide;toluene at 95; for 3 h;
Steps:
Synthesis of Acid Chloride Product (A)
4,4'-diphenyl ether dicarboxylic acid 25.3 g (0.096 mol), 0.85 g (0.012 mol) of dimethylformamide and 80 ml of toluene was prepared. For the first mixed solution in the stirring state, 58.4 g (0.46 mol) of thionyl chloride, And 20 ml of toluene Was gradually added dropwise at room temperature. After completion of the dropwise addition, the liquid obtained was heated to 95 ° C., It was refluxed for 3 h. Then, by allowing the yellow transparent liquid obtained after heating / refluxing to cool, It has the following molecular structure 4,4'-diphenyl ether dicarboxylic acid chloride (Hereinafter referred to as "acid chloride (A)" In some cases) as a toluene solution. further, The toluene solution was applied to a rotary evaporator, and toluene, Thionyl chloride and hydrogen chloride were removed, 4,4'- Diphenyl ether dicarboxylic acid chloride solid 26.9 g (0.091 mol, 95% yield) Was obtained.
