Praxair

Founded in 1907, Praxair was the largest industrial gases company in North and South America, and the third-largest worldwide by revenue.

During the First World War, however, it was confiscated and in 1917, it joined with 4 other chemical companies under the name Union Carbide and Carbon Corporation, while maintaining a separate identity.

[6] In August 2016 it was publicly announced that the American Praxair was in official negotiations to merge with the German Linde Group, which would form the world's largest gas supplier.

[21] In April, 2017 Linde again rejected a request, from German private-investor association DSW, for a shareholder vote at its annual general meeting in May.

Upon completion of merger, it formed a new American German company Linde plc domiciled in Ireland and headquartered in Surrey for tax purposes.
