Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
Convention of 1836 Convention of 1836 The "Convention of 1836" was the meeting of elected delegates in Washington-on-the-Brazos, Texas in March 1836. The Texas Revolution had begun five months previously, and the interim government, known as the Consultation, had wavered over whether to declare independence from Mexico or pledge to uphold the repudiated Mexican Constitution of 1824.
