5-Methyl-1,3-benzenedicarboxylic acid Use and Manufacturing

DIPEA (0.33 mL, 1.867 mmol) was added dropwise to a mixture of 4 (200 mg, 0.373 mmol) and ] 0.2111111 01211 (view 3) 2.61120, 0.10111111 011 ~ '- bis (3-pyridyl) pyridine-3, 5-dicarboxamide, Methyl isophthalic acid and 12.5 mL of H2O were successively added to a 25 mL beaker, stirred at room temperature for 60 min, The suspended mixture was obtained and the pH of the suspension mixture was adjusted to 6.9 with 0.5 mol / L NaOH solution, transferred to 25 mL of high pressureThe reactor was heated to 120 ° C at a heating rate of 10 ° C / h, and maintained at a temperature of 144 ° C under a hydrothermal condition at a cooling rate of 2.5 ° C / hThe temperature was lowered to room temperature to obtain a colorless crystal, which was washed alternately with deionized water and ethanol 4 times, and air-dried at room temperature to obtain[Zn (L2) (mip)] n, the yield of 81percent
