HCL Technologies Limited (d/b/a HCLTech) is an Indian multinational information technology (IT) consulting company headquartered in Noida.Founded by Shiv Nadar, it was spun out in 1991 when HCL entered into the software services business.
In part because of its high polarity, HCl is very soluble in water (and in other polar solvents). Upon contact, H 2 O and HCl combine to form hydronium cations [H 3 O] + and chloride anions Cl − through a reversible chemical reaction: HCl + H 2 O → [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid.
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 in the food industry.

Sample of a hydrochloride salt, triethylammonium chloride In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine).
The commercially most relevant field of application for HCl regeneration processes is the recovery of HCl from waste pickle liquors from carbon-steel pickling lines. Other applications include the production of metal oxides such as, but not limited, to Al 2 O 3 and MgO, as well as rare-earth oxides, by pyrohydrolysis of aqueous metal chloride or rare-earth chloride solutions.
Nadar's daughter Roshni Nadar is now chairwoman of HCL. She was the manager of HCL when Nadar started it in the 1990s. [31] His wife, Kiran Nadar, is an art collector and philanthropist. [32] Nadar and his wife are active bridge players and sponsors of the HCL Bridge Tournament in India.
Chloroform converts slowly in the presence of UV light and air to the extremely poisonous gas, phosgene (COCl 2), releasing HCl in the process. [75] 2 CHCl 3 + O 2 → 2 COCl 2 + 2 HCl. To prevent accidents, commercial chloroform is stabilized with ethanol or amylene, but samples that have been recovered or dried no longer contain any stabilizer.
