DMSO Gel Preparation Data. I have a method that uses a 1%w/v sodium perchlorate in 40:60:1 water/acetonitrile/acetic acid mobile phase. 4 NaClO 3 → NaCl + 3 NaClO 4. On impregnating porous silicon with sodium perchlorate it forms an explosive composite which has been investigated. Not so sure about a good solvent, but I wouldn't want to dissolve any chlorate or perchlorate salts in an alcohol. Data follow in Table I11 for liquid- liquid equilibria. Results and Discussion The experimental solubility results are reported in Tables I1 and 111. It is a strong oxidizing agent. Relative Hansen Solubility Parameter Data 9. On the other hand, if we consider this description to simply mean "10% acetonitrile", this implies that 20 mM phosphoric acid (sodium) buffer solution (pH 2.5) is used, and is diluted with acetonitrile. Sodium perchlorate is a water soluble perchlorate salt. Since the sodium perchlorate can also decompose and the sodium chlorate can give off oxygen without making perchlorate, this can be a lossy way to produce this compound. Sodium perchlorate is the precursor to many other perchlorate salts, often taking advantage of their low solubility relative to NaClO 4 (209 g/100 mL at 25 °C). 2) The reagent is dissolved in 1 L of an aqueous solvent such as methanol - water. I have heard some bad stories about the use of sodium perchlorate in mobile phase (explosions etc). SODIUM PERCHLORATE Critical evaluation Binary systems Solubility in water Solubility in 020 Solubility in other solvents II Ternary systems Solubility in mixed solvents Systems NaCI04-inorganiccompound-H20 ... Solubility Data Project and Chairman ofCommission V.8 until shortly before his untimely Perchlorates are the slowest oxidizers or the chloro-oxoanion series but their stand reduction potentials are still around ~(+1.2) V. Maybe acetonitrile … Eluent: 0.1 M sodium perchlorate in 22.5% acetonitrile Flow rate: 1.0 mL/min Temp. 1) Sodium 1-Heptanesulfonate (IPC-ALKS-7) [I0345] 1.011 g (0.005 mol) is weighed out. Uses. Packaging 100, 500 g … solubility of salt in mass fraction. Suggested DMSO Formulations for Industrial Solvent Replacement 10. sodium perchlorate Physical appearance: colorless rhombic crystals Empirical formula (Hill's system for organic substances): ClNaO 4 Structural formula as text: NaClO4 Molar/atomic mass: 122.44 Melting point (°C): 482 Destruction point (°C): 482 Solubility (g/100 g of solvent): 1-butanol: 1.86 (23°C) liquid ammonia: 278.3 (-33°C) 3) The pH is adjusted to 3.5 by the addition of aqueous phosphoric acid (50%). The effect of sodium perchlorate on the solubility of sodium acetyl- acetonate in acetonitrile was explored. The reaction is considerably faster than a perchlorate cell however. is highly soluble and dissociates completely to ammo-nium and perchlorate ions upon dissolving in water (equation 1): NH ClO s NH aq ClO aqwater 44 4 4() → +()+ –()(1) It is likely that most of the ammonium has been biode-graded and the cation is now best viewed as mostly sodium (Na+) or … Hansen Solubility Parameter Data for Selected Polymers 11. : 25 °C Detection: Differential refractometer Sample: Standard sodium polystyrene sulfonate Elution Volume (ml) Log Molecular Weight ① α-2500 ② α-3000 ③ α-4000 ④ α-5000 ⑤ α-6000 ⑥α-M Fig. Thanks 6. Has anyone got any experience of using sodium perchlorate and what special precautions should be taken. Perchloric acid is made by treating NaClO 4 with HCl.. It is prepared by electrolyzing aqueous sodium chlorate solution. Ammonium and potassium perchlorate, of interest in pyrotechnics, are prepared by double decomposition from a solution of sodium perchlorate and potassium or ammonium chlorides. 4 TSK-GEL Alpha Series Calibration Curve the determination of salt solubility and one for the deter- mination of water content in the solvent mixture by means of a coulometric Karl-Fischer titration (6). Data related to the solvent properties of DMSO are given in tables on the following pages: 8. Pharmaceutical Excipient Solubility Data 7. Solubility enhancements ranging from two to four-fold were observed, indicating a behavior qualitatively similar to the lithium case. (sodium) buffer solution (pH 2.5) to that of acetonitrile is 9:1; in other words, amounts corresponding to this ratio are measured out and mixed.
