Effect of Hydrochloric Acid on Leaching Behavior of Calcareous Phosphorites
The bulk of the world's phosphate reserves is located in sedimentary horizons that contain appreciable amounts of carbonate. During beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers. This reject also mostly contains low tricalcium phosphate and high carbonate content. In this study, experiments have been carried out to reduce/eliminate car...
متن کاملHydrochloric Acid-Catalyzed Levulinic Acid Formation from Cellulose: Data and Kinetic Model to Maximize Yields
In this study, the kinetics of the acid catalyzed hydrolysis of microcrystalline cellulose (Avicel PH101) to levulinic (LA) and formic (FA) acids was investigated in a batch reactor over the following range of conditions: 160–200 C, hydrochloric acid concentrations of 0.309–0.927 M (11.3–33.8 g/l), cellulose concentrations of 49.8–149 mM (8.06–24.1 g/l), and residence times of 0–50 min. The max...
متن کاملMassive gastric necrosis from hydrochloric acid ingestion.
Severe gastrointestinal-tract injury due to ingestion of caustic substances is not an infrequent problem in the emergency department. We report the case of a 57-year-old male who developed massive hemorrhagic, caustic gastric necrosis due to the ingestion of a non-diluted solution containing hydrochloric acid, which propitiated an urgent surgical procedure. The esophago-gastrectomy specimen sho...
متن کاملPlease advise on infusing hydrochloric acid
The approach to and treatment of metabolic alkalosis has made great strides in recent decades and molecular mechanisms have been unraveled. Thus, we were perplexed to receive a request for assistance with hydrochloric acid management. This treatment was not that unusual in the distant past but is nowadays thankfully uncommon. A double-take is an expression of surprise in body language. The cons...
متن کاملHydrochloric Acid: Physiological Functions and Clinical Implications
Hydrochloric acid (HCl) secretion assists protein digestion by activating pepsinogen to pepsin, renders the stomach sterile against orally-ingested pathogens, prevents bacterial or fungal overgrowth of the small intestine, encourages the flow of bile and pancreatic enzymes, and facilitates the absorption of a variety of nutrients, including folic acid, ascorbic acid, beta-carotene, non-heme iro...
