  2. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    Hydrogen chloride is produced by combining chlorine and hydrogen: Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure product, e.g. for use ...

  3. Element–reactant–product table - Wikipedia

    en.wikipedia.org/wiki/Element–reactant...

    An element–reaction–product table is used to find coefficients while balancing an equation representing a chemical reaction. Coefficients represent moles of a substance so that the number of atoms produced is equal to the number of atoms being reacted with. [1] This is the common setup: Element: all the elements that are in the reaction ...

  4. Stephen aldehyde synthesis - Wikipedia

    en.wikipedia.org/wiki/Stephen_aldehyde_synthesis

    Stephen aldehyde synthesis, a named reaction in chemistry, was invented by Henry Stephen (OBE/MBE).This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl 2), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH 2] + Cl −) with water (H 2 O).

  5. Gas evolution reaction - Wikipedia

    en.wikipedia.org/wiki/Gas_evolution_reaction

    In this example, diatomic hydrogen gas is released. Dilute hydrochloric acid can be used in place of dilute sulfuric acid. A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative): + +

  6. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. [25] Hydrogen chloride, not hydrochloric acid, is used more widely in industrial organic chemistry, e.g. for vinyl chloride and dichloroethane. [8]

  7. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. [1]

  8. Mannheim process - Wikipedia

    en.wikipedia.org/wiki/Mannheim_process

    The Mannheim process is an industrial process for the production of hydrogen chloride and sodium sulfate from sulfuric acid and sodium chloride. [1] The Mannheim furnace is also used to produce potassium sulfate from potassium chloride. [2] The Mannheim process is a stage in the Leblanc process for the production of sodium carbonate.

  9. Organochlorine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organochlorine_chemistry

    Alkenes react with hydrogen chloride (HCl) to give alkyl chlorides. For example, the industrial production of chloroethane proceeds by the reaction of ethylene with HCl: [citation needed] H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose:
