Abstract:
Bromobiphenols comprising 2,2' ,6,6'-tetraalkyl-3,3',5,5'-tetrabromo-1,1'-biphenols and derivatives thereof are employed as fire-retardant additives for normally flammable resins yielding fire-retardant polymeric compositions. These fire-retardant compositions are thermally stable and can be molded or formed into fire-retardant articles, such as films, sheeting, fibers, laminates, or reinforced plastics by conventional techniques.
Abstract:
Anti-knock gasoline fuel compositions are provided including anti-knock additives and mixtures thereof. The octane quality of fuel for an internal combustion engine improved with the anti-knock additives.
Abstract:
The invention relates to use of trioxepan compounds of formula I with R1-3 being independently selected from substituted or unsubstituted hydrocarbyl groups in the process to make fuels with improved ignition properties. Preferably, R1 and R3 are selected from lower alkyl groups, such as methyl, ethyl, and isopropyl, while R2 is preferably selected from methyl, ethyl, isopropyl, isobutyl, amyl, isoamyl, cyclohexyl, CH3C(O)CH2—, C2H5OC(O)CH2—, HOC(CH3)2CH2—, and

Abstract:
A fuel composition for internal combustion engines, and more particularly, a fuel composition for internal combustion engines containing less than about 0.5 gram of lead per gallon of fuel is described. The fuel provides acceptable valve seat protection in engines designed to operate on leaded fuels. A further aspect of the invention is to reduce deposit formation within the cylinders.
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.
