Paul Sabatier

Born 5 Nov 1854; died 14 Aug 1941 at age 86. Organic chemist who shared the Nobel Prize for Chemistry in 1912 with Victor Grignard. Sabatier researched in catalytic organic synthesis, and discovered the use of finely divided nickel as a catalyst in hydrogenation (the addition of hydrogen to molecules of carbon compounds). The margarine, oil hydrogenation, and synthetic methanol industries grew out of this work. He found that increasing the surface area of catalysts such as copper and nickel by finely dividing them greatly increases their effectiveness. Sabatier did wide-ranging research of the use of catalysts in organic chemistry syntheses, revealing metals other than nickel, though less effective, can also behave as catalysts.
