deprotonation of carboxylic acid increases solubility

Posted on:

I know that answer but why?

Screening process of norfloxacin glutarate. Physical Properties: The polar nature of both the O-H and C=O bonds (due to the electonegativity difference of the atoms) results in the formation of strong hydrogen bonds with other carboxylic acid molecules or other H-bonding systems (e.g. However, the characteristic peaks of 10.56 degrees and 25.02 degrees attributed to NFX and 13.77 degrees, 19.54 degrees, 27.23 degrees and 37.34 degrees attributed to GLU disappeared. (Powder X-Ray Diffraction, PXRD) Analysis. Solubility Lower chain carboxylic acids are soluble in water but higher chain carboxylic acids are insoluble. A Bruker VERTEX 70 Fourier infrared spectrometer and potassium bromide tabletting method were used in this paper, with the scanning wavenumber range 4000 - 400 cm−1 and the resolution of 4 cm−1. Among the salts formed by different ratios of NFX and GLU, the stretching vibration 3434 cm−1 absorption peak of N-H originally attributed to the NFX piperazine ring was red shifted to different degrees. The aqueous solubility of norfloxacin is increased after the formations of all salts. The carboxylic acids with low molar mass up to four carbon atoms are freely soluble in water. The apparent water solubility was calculated by measuring the absorbance of each group of NFX salts in water using Metash UV-5500PC spectrophotometer at λmax 276 nm. However, the literature has not systematically studied the effect of acid salting with it on its solubility. Journal of Physical Organic Chemistry 1997 , 10 (7) , 537-541. In this contribution, we demonstrate the syntheses, characteristics, and solubility of pharmaceutical salts assembled by zwitterionic hydrogen-bonding interactions between NFX and diverse linear saturated dicarboxylic acids (Figure 1). Screening process were shown in Table 1.

Jeevarajan, A. S.; Carmichael, I.; Fessenden, R. W. (1990). (Chem.) The effect of pKa on the solubility and dissolution profile of drug salts are investigated in pure water. The crystallization of norfloxacin, an antibacterial fluoroquinolone compound, with different saturated aliphatic dicarboxylic acids yields five novel pharmaceutical salts via molecular recognition. Furthermore, regeneration strategies are discussed, aiming to provide direction towards regenerations that do not further dilute streams that are already diluted before the LLX process. This may have a certain relationship with the accumulation of different crystals.

Carbonylation is versatile method when coupled to the addition of water. After the solution was crystallized and filtered, the resulting crystals were washed with a few drops of purified water and air-dried naturally. Thus, when acetic acid is placed into a solution of sodium bicarbonate at pH 8.5, less than 0.020 of the carboxylic acid remains.

Evaporation of part of the diluent before back-extraction is most energy efficient. A sufficient amount (70 mg) of NFX was placed in a 250 mL volumetric flask, purified water was added to the calibration line, placed in a constant temperature shaker at 25˚C and 150 rpm for 24 h, filtered, and the obtained solid was dried to constant weight in DHG Series Heating and Drying Oven (Shanghai Jinghong, China), and the remaining solid was weighed at 24 mg.
