Sohio’s exploratory program in catalytic oxidation began in 1953 at Cornell Road laboratory in Cleveland, with the first successful lab experiment conducted in 1957.
Pilot plant scale-up, first production facility design, and licensing activity was conducted simultaneously
World’s first plant utilising the Sohio process (AN #1 at Lima, OH) was completed in 1960, transforming the production of Acrylonitrile. The new process required one-tenth the capital cost vs. existing technology, allowing for larger scale plants and higher product purity.
Within 5 years all acetylene-based production disappeared, and producers licensed from Sohio.
