Editing Clathrate hydrate (section)

== History and etymology==
Clathrate hydrates were discovered in 1810 by [[Sir Humphry Davy|Humphry Davy]].<ref>{{cite web |url=http://condor.wesleyan.edu/ethomas/ees123/clathrate.htm |title=Clathrates: little known components of the global carbon cycle |accessdate=13 December 2007 |date=November 2004  |last1=Thomas |first1=Ellen |author-link=Ellen Thomas (scientist) |publisher=Wesleyan University}}</ref> Clathrates were studied by P. Pfeiffer in 1927 and in 1930, E. Hertel defined "molecular compounds" as substances decomposed into individual components following the [[mass action law]] in solution or gas state. Clathrate hydrates were discovered to form blockages in gas pipelines in 1934 by Hammerschmidt that led to increase in research to avoid hydrate formation.<ref>{{Cite journal |last=Hammerschmidt |first=E.

M. Powell]] analyzed the crystal structure of these compounds and named them ''clathrates''. Gas production through [[Methane clathrate|methane hydrates]] has since been realized and has been tested for energy production in Japan and China.<ref name=":0" />

The word ''clathrate'' is derived from the [[Latin language|Latin]] {{wikt-lang|la|clathratus}} ({{lang|la|clatratus}}), meaning 'with bars, [[Crystal structure|lattice]]d'.<ref>[http://lysy2.archives.nd.edu/cgi-bin/WORDS.EXE?clathrate Latin dictionary] {{webarchive|url=https://web.archive.org/web/20120414202654/http://lysy2.archives.nd.edu/cgi-bin/WORDS.EXE?clathrate |date=2012-04-14 }}</ref>
