Behavior of Calcium Sulfate at High Temperatures
Differential heating curves were used to study the behavior of calcium sulfate at high temperatures. After cooling, the material was examined by means of the petrographic microscope and by study of its X-ray pattern. It was found that the beta-to-alpha transition of calcium sulfate occurs at approximately 1,214° C, and the conclusion of i ts discoverer that the high temperature form is unstable...
متن کاملEvaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature
Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids. Therefore, in this study, we focused on evaluating the dissolution of the industrial barite particles in different chelating agents. Chelating agents; such as, dieth...
متن کاملPrediction of Activity Coefficients of Electrolytes in Aqueous Solutions at High Temperatures
A recently published model for the excess Gibbs energy of aqueous solutions containing mixed electrolytes (Lu and Maurer, 1993) is extended from 298 K to temperatures up to 573 K. The extension is achieved by introducing a universal relation for the influence of temperature on some model parameters. Although parameters are still ion specific, the influence of temperature on those parameters is ...
متن کاملSeparation of Formic Acid from Aqueous Solutions by Liquid Extraction Technique at Different Temperatures
In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...
متن کاملStability of Cefpirome Sulfate in Aqueous Solutions.
The influence of pH on the stability of cefpirome sulfate was investigated in the pH range of 0.44 - 13.00. The degradation of cefpirome sulfate as a result of hydrolysis was a pseudo-first-order reaction. General acid-base hydrolysis of cefpirome sulfate was not observed. In the solutions of hydrochloric acid, sodium hydroxide, acetate, borate and phosphate buffer, k(obs) = k(pH) because speci...
