In the 17th century, <a href="/wiki/Johann_Rudolf_Glauber" title="Johann Rudolf Glauber">Johann Rudolf Glauber</a> used salt (<a href="/wiki/Sodium_chloride" title="Sodium chloride">sodium chloride</a>) and <a href="/wiki/Sulfuric_acid" title="Sulfuric acid">sulfuric acid</a> for the preparation of <a href="/wiki/Sodium_sulfate" title="Sodium sulfate">sodium sulfate</a>, releasing hydrogen chloride gas (see production, above). In 1772, <a href="/wiki/Carl_Wilhelm_Scheele" title="Carl Wilhelm Scheele">Carl Wilhelm Scheele</a> also reported this reaction and is sometimes credited with its discovery. <a href="/wiki/Joseph_Priestley" title="Joseph Priestley">Joseph Priestley</a> prepared hydrogen chloride in 1772, and in 1810 <a href="/wiki/Humphry_Davy" title="Humphry Davy">Humphry Davy</a> established that it is composed of <a href="/wiki/Hydrogen" title="Hydrogen">hydrogen</a> and <a href="/wiki/Chlorine" title="Chlorine">chlorine</a>.<sup id="cite_ref-25" class="reference"><a href="#cite_note-25"><span class="cite-bracket">[</span>25<span class="cite-bracket">]</span></a></sup> </p><p>During the <a href="/wiki/Industrial_Revolution" title="Industrial Revolution">Industrial Revolution</a>, demand for <a href="/wiki/Alkaline" class="mw-redirect" title="Alkaline">alkaline</a> substances such as <a href="/wiki/Soda_ash" class="mw-redirect" title="Soda ash">soda ash</a> increased, and <a href="/wiki/Nicolas_Leblanc" title="Nicolas Leblanc">Nicolas Leblanc</a> developed a new industrial-scale process for producing the soda ash. In the <a href="/wiki/Leblanc_process" title="Leblanc process">Leblanc process</a>, salt was converted to soda ash, using sulfuric acid, limestone, and coal, giving hydrogen chloride as by-product. Initially, this gas was vented to air, but the <a href="/wiki/Alkali_Act" class="mw-redirect" title="Alkali Act">Alkali Act</a> of 1863 prohibited such release, so then soda ash producers absorbed the HCl waste gas in water, producing hydrochloric acid on an industrial scale. Later, the <a href="/w/index.php?title=Hargreaves_process&action=edit&redlink=1" class="new" title="Hargreaves process (page does not exist)">Hargreaves process</a> was developed, which is similar to the Leblanc process except <a href="/wiki/Sulfur_dioxide" title="Sulfur dioxide">sulfur dioxide</a>, water, and air are used instead of sulfuric acid in a reaction which is exothermic overall. In the early 20th century the Leblanc process was effectively replaced by the <a href="/wiki/Solvay_process" title="Solvay process">Solvay process</a>, which did not produce HCl. However, hydrogen chloride production continued as a step in hydrochloric acid production. </p><p>Historical uses of hydrogen chloride in the 20th century include hydrochlorinations of <a href="/wiki/Alkynes" class="mw-redirect" title="Alkynes">alkynes</a> in producing the chlorinated <a href="/wiki/Monomer" title="Monomer">monomers</a> <a href="/wiki/Chloroprene" title="Chloroprene">chloroprene</a> and <a href="/wiki/Vinyl_chloride" title="Vinyl chloride">vinyl chloride</a>, which are subsequently <a href="/wiki/Polymer" title="Polymer">polymerized</a> to make polychloroprene (<a href="/wiki/Neoprene" title="Neoprene">Neoprene</a>) and <a href="/wiki/Polyvinyl_chloride" title="Polyvinyl chloride">polyvinyl chloride</a> (PVC), respectively.
