Murray Raney

 ( 20th-century American Engineers ) 

Murray Raney (October 14, 1885 – March 3, 1966) was an American mechanical engineer born in Carrollton, Kentucky. He was the developer of a nickel catalyst that became known as Raney nickel, which is often used in industrial processes and scientific research for the hydrogenation of multiple present in .

Biography Raney was born in Carrollton, Kentucky, to William Washington Raney (1848–1929) and Katherine Wright Raney (1857–1935). Without having attended high school,W.R. Grace & Co. (2004) History Murray Raney . Retrieved December 25, 2005. he obtained his bachelor's degree in mechanical engineering from the University of Kentucky in 1909. Following his graduation he became a teacher at the Eastern Kentucky State Normal College and was also in charge of the heating and lighting facilities there until 1910.

From 1910 until 1911 he worked in the room of the Fort Orange Paper Company in Castleton-on-Hudson, New York. In 1911 he moved to Springfield, Illinois to work in the production of at A. L. Ide Engine Company, where he stayed until 1913. That same year he moved to his final residence in Chattanooga, Tennessee, to work for the Chattanooga Railway, Light & Power Co as a electricity salesman.

Raney joined the Lookout Oil & Refining Company in 1915. He was assigned to work as an assistant manager in the production of hydrogen used in the hydrogenation of . It was during this time he started to work in the preparation of what later became known as "Raney" catalysts. He left Lookout Oil in 1925 to take a sales manager position at Gilman Paint and Varnish Co., eventually becoming president of the company. In 1950 he left Gilman Paint and founded the Raney Catalyst Company. He then started to dedicate full-time to the production of his catalysts. This company was bought by W.R. Grace and Company in 1963 and still produces Raney nickel to this day.

Raney was twice married, first on June 12, 1920, to Katherine Elizabeth Macrae (1883–1935), with whom he had one daughter. His second marriage was to Laura Ogden McClellan (1898–1953) on March 31, 1939. He was awarded an honorary Doctor of Science degree in 1951. He was member of the American Chemical Society and the American Oil Chemists' Society. He was granted a total of six American and five for the development of his catalysts and metallurgical processes needed for their preparation.

Development of Raney nickel During his time at Lookout Oil and Refining Raney was responsible for the production of hydrogen which was used in the hydrogenation of vegetable oils. During that time the industry used a nickel catalyst prepared from nickel(II) oxide. Believing that better catalysts could be produced, around 1921 he started to perform independent research on this matter while still working for Lookout Oil. In 1924 he produced an approximately 1:1 nickel-silicon alloy which, after being treated with sodium hydroxide to remove the silicon, was found to be five times more active than the best catalyst used in the hydrogenation of cottonseed oil. He was granted a US patent for this discovery in 1925.Raney, Murray (1925). " Method of Preparing Catalytic Material ". US Patent 1563587, issued 1925-12-01. To this, Raney himself said in an interview "I was just lucky... I had an idea for a catalyst and it worked the first time."

In 1926 Raney produced a nickel-aluminium alloy, also in a 1:1 ratio, following a procedure similar to the one used for the nickel-silicon alloy, and he found that the resulting catalyst was even more active than the previous one. This catalyst, now commonly known as Raney nickel, was the subject of a patent he obtained in 1927.Raney, Murray (1927). " Method of producing Finely Divided Nickel ". US Patent 1628190, issued 1927-05-10

The Murray Raney Award

In 1992 the Organic Reactions Catalysis Society (ORCS) created the Murray Raney Award "for contributions in the use of sponge metal catalysts in organic synthesis". The award is given out every two years at the annual ORCS conference. the following scientists have been recipients of the award:

• 1992 – Stewart Montgomery
• 1994 – Pierre Fouilloux
• 1996 – Mark Wainwright
• 1998 – Anatoly Fasman
• 2000 – Jozsef Petró
• 2002 – Akira Tai
• 2004 – Jean Lessard (chemist)
• 2006 – Isamu Yamauchi
