Abstract:
A process for stabilizing solutions of metal carbonyls in organic solvents, preferably in hydrocarbons, in which one or more aluminum-containing, organic compounds are dissolved in the solutions as stabilizers. The aluminum in such compounds is directly bonded to carbon and/or oxygen atoms. More specifically, the aluminum containing organic compounds are reaction products between aluminum alkoxides and one or more compounds having the formula:
WHEREIN R1 represents hydrogen, alkyl having up to 8 carbon atoms, aryl or aralkyl having up to 10 carbon atoms, alkoxy having up to 8 carbon atoms, aryloxy or aralkoxy having up to 10 carbon atoms, or a group having the formula:
AND THE GROUPS R2, R3, R4 and R5 each, and independently of each other, represent hydrogen, alkyl having up to 8 carbon atoms, or aryl or aralkyl having up to 10 carbon atoms. The aluminumcontaining organic compounds can be added to the solutions of metal carbonyls in an amount corresponding to 1 part by weight of aluminum to 50 to 200 parts by weight of the metal in the metal carbonyl.
Abstract:
A method of reducing manganese containing deposits formed on the surfaces of jet engines from burning fuel containing organomanganese compounds as a smoke reducer is described. The deposits are reduced by adding an organic molybdenum compound to the organomanganese containing fuel. Cyclopentadienyl manganese tricarbonyl compounds are useful organomanganese compounds; molybdenum naphthenate is a useful molybdenum compound.
