In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3112-31-0, name is 1H-Pyrazole-3,5-dicarboxylic acid belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C5H4N2O4
A mixture of LaCl3¡¤7H2O (0.187g, 0.5mmol), H3pdc (0.175g, 1.0mmol), NaOH (0.041g, 1.0mmol) and H2O (5mL) was placed in a 23mL Teflon-lined Parr acid digestion bomb and heated for two days at 180¡ãC under autogenous pressure. Upon cooling to room temperature, solution was separated from the solid phase, and after filtration precipitate washed with water and acetone, respectively. The product was dried at ambient temperature. The colorless crystals of 1 were obtained with high yield and the synthesized single crystals suited for X-ray diffraction analysis. Yield ca. 86percent (based on La). Initial pH was 2.50; final pH was 1.88. Crystalline 1 is insoluble in water and common solvents and stable in air. Anal. Calc. for C15H15La2N6O18: C, 21.29; H, 1.78; N, 9.93. Found: C, 21.18; H, 2.18; N, 9.67percent. IR data (KBr pellet, cm?1): 3410(m), 3160(m), 1593(vs), 1458(m), 1352(vs), 1311(vs), 1017(s), 837(w), 783(s), 629(w).
The synthetic route of 3112-31-0 has been constantly updated, and we look forward to future research findings.
