Vinyl Chloride - History

History

Vinyl chloride was first produced in 1835 by Justus von Liebig and his student Henri Victor Regnault. They obtained it by treating 1,2-dichloroethane with a solution of potassium hydroxide in ethanol.

In 1912, Frans, a German chemist working for Griesheim-Elektron, patented a means to produce vinyl chloride from acetylene and hydrogen chloride using mercuric chloride as a catalyst. While this method was widely used during the 1930s and 1940s in the West, it has since been superseded by more economical processes based on ethylene in the United States and Europe. It remains the main production method in China.

Famous quotes containing the word history:

    The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.
    Gilbert Keith Chesterton (1874–1936)

    The true theater of history is therefore the temperate zone.
    Georg Wilhelm Friedrich Hegel (1770–1831)

    All objects, all phases of culture are alive. They have voices. They speak of their history and interrelatedness. And they are all talking at once!
    Camille Paglia (b. 1947)
