Acetylene Synthesis

Good Essays

Acetylene discovered by Edmund chemist in 1836 Who known it as a "new combination of hydrogen"..In 1860 it was made by a new technique by passing over red hot tube, vapours of organic compounds (methanol, ethanol, etc.) by Marcellin Berthelot . He also found that ethyne can be produced or formed by sparking electricity through mixed cyanogens and hydrogen gases .

1.1 USES:
Acetylene (C2H2 ) is extremely reactive , having commercial importanc organic compound. it's employed in Fusion welding (process of joining metallic parts).Acetylene is employed as a primarily staple for the synthesis of no of organic chemicals . massive quantities of ethyne are employed in metal cutting. Its small scale use of is within the preparation of vinyl ethers from alcohols along with phenols using Na-or K-hydroxide as catalyst in liquid phase. Large amount of alcohols will be vinylated however solely few has business

The replacement of a hydrogen atom on ethyne by a metal atom beneath basic conditions leads to the formation of metal acetylides that react with water in an exceedingly extremely heat-releasing manner to yield ethyne and alternative corresponding metal hydroxide
Acetylene can be hydrogenated to ethene and ethane.. The reduction of ethyne occures in an exceedinglyn ammonical solution of chromous chloride or in a solution of chromous salts in H2SO4. The selective catalytic hydrogenation of ethyne to ethylene, that yield over supported Group eight metal catalyst, is of nice industrial importance within the manufacture of ethyne by thermal transformation of organic compound.
