How is prechloric acid produced from hydrochloric acid in industry?3 answersPrechloric acid is produced from hydrochloric acid in industry through various methods. One method involves vacuum purification, where industrial hydrochloric acid is added to a distiller and heated to boil. The hydrogen chloride gas is then condensed and absorbed to obtain low concentration acid, which is further processed to increase the concentration of hydrogen chloride. When the concentration reaches more than 36%, the hydrochloric acid is subpackaged and stored. Another method involves ion separation, where dilute hydrochloric acid is separated into liquid concentrated hydrochloric acid and vaporized hydrochloric acid. The vaporized hydrochloric acid is then removed through condensation, while the dilute hydrochloric acid is regenerated. Additionally, hydrochloric acid can be produced by capturing hydrogen chloride from exhaust gas and removing iron ions through refinery columns. Furthermore, hydrochloric acid can be prepared as a by-product through tail gas absorption in chloroacetic acid production process. Finally, hydrochloric acid-containing waste liquid can be regenerated through microwave heating and condensation.
Comparing the removal of hydrochloric acid fumes with water or mixed with NaCl, which is better?5 answersComparing the removal of hydrochloric acid fumes with water or mixed with NaCl, the use of water is better. The invention described inpresents a rectangular multi-cavity type electrochemical water treatment equipment that can effectively remove hazardous substances and prepare hydrochloric acid through salt removal. This equipment has a large contact area between water and electrodes, resulting in high decontamination capacity. Additionally, the use of a hollow ionic membrane enhances the treatment effect. On the other hand,discusses the use of adsorbents and chemical removers for chlorine retention during PVC pyrolysis. While the chemical removers showed chlorine retentions of up to 71%, the adsorbents only achieved a maximum of 19% retention. Therefore, in the context of hydrochloric acid fumes removal, the use of water, as described in, would be more effective than mixing with NaCl.
What is the reaction of cobalt chloride with hydrochloric acid?5 answersThe reaction of cobalt chloride with hydrochloric acid involves leaching cobalt hydroxide with hydrochloric acid to produce a cobalt chloride solution. In one method, electrolytic cobalt, mixed acid, and water are reacted in a series of reaction containers, with the solution overflowing from one container to the next and reacting with electrolytic cobalt and water. Another method involves two-stage leaching, where a nickel chloride solution is added to a reaction kettle along with hydrochloric acid and leaching residue, and the solution is filtered to produce a second-stage leaching liquid and residue. The second-stage leaching liquid is then added to a one-stage leaching kettle along with nickel hydroxide cobalt to adjust the pH and produce a one-stage leaching liquid, which is further processed to obtain the nickel chloride solution. The specifics of cobalt chloride sublimation during the reaction with chlorine have also been studied.
Why is hydrochloric acid added to adjust the pH value of a solution?1 answersHydrochloric acid is added to adjust the pH value of a solution because it can either increase or decrease the acidity of the solution, depending on the desired pH level. In some cases, hydrochloric acid is added to lower the pH and make the solution more acidic. For example, in the context of purifying and preparing highly-pure iron solutions, hydrochloric acid is added to adjust the pH value and achieve selective separation of iron and chromium. On the other hand, hydrochloric acid can also be added to increase the acidity of a solution. In the context of recovering platinum from an aqueous solution, hydrochloric acid is added to acidify the solution and facilitate the separation of platinum using an organic solvent. Overall, the addition of hydrochloric acid allows for precise control of the pH value, which is important for various chemical processes and separations.
How to chlorinate the upen well?5 answersTo chlorinate an open well, a method for preparing chlorcosane can be used. This method involves continuously causing paroline and chlorine to react in a series of reaction kettles under the influence of an optical catalyst. The unreacted paroline and chlorine from each reaction kettle are then transferred to the subsequent reaction kettle for further chlorination. By adopting low chlorine dosage in the later stages of the reaction, higher increment of the chlorcosane products can be achieved. This method offers a beneficial effect in terms of product yield.
