摘要:
Methods and apparatus for preparing gaseous compositions comprising a metal carbonyl, preferably at ppm concentration, are disclosed. The methods comprise placing metal, preferably in the form of filings, of the metal carbonyl to be produced into a first test vessel at a first temperature, and then pressurizing the first test vessel with a gas comprising carbon monoxide from a carbon monoxide source vessel. The contents of the first vessel are then heated to a second temperature and at a rate sufficient to initiate metal carbonyl formation, thereby forming a gas composition comprising a metal carbonyl. The reaction is then quenched by transferring some of the gas composition comprising a metal carbonyl from the first test vessel to a second test vessel which is at a third temperature, the third temperature being lower than the second temperature. Finally, the gas composition is diluted in the second test vessel with an inert gas (preferably argon) from an inert gas source container.

摘要:
Gaseous streams of carbon monoxide containing nickel and iron carbonyls are contacted with cooled liquid iron pentacarbonyl to dissolve the carbonyls and to provide purified carbon monoxide. When the liquid iron pentacarbonyl has dissolved controlled amounts of nickel carbonyl, the solution is fractionally distilled to recover nickel carbonyl and liquid iron pentacarbonyl which can be recycled. The process can also be conducted under pressure and in conjunction with intermediate pressure carbonyl processes for recovering nickel.
