This invention pertains to an improved energy-saving fuel additive for jet engines, gasoline and diesel engines, including additions to domestic heating and light industrial oils (#2 and #3) and residual or bunker fuel (#4, #5, and #6), which comprises as active ingredients a catalytic mixture of a major proportion of picric acid and a minor proportion of cupric sulfate.______________________________________ Cupric sulfate .01-.03% Picric acid 1-2% Methanol 35-50% Isopropyl alcohol 15-5% Toluene 43-48% Nitrobenzene .6-1.0% Primene 81R .5-1.0% ______________________________________ Additional variations include (1) the replacement of the toluene with about 10% methanol and 90% isopropyl alcohol for toxicity reasons and (2) replacement of the toluene with 10% methanol, 45% isopropyl alcohol, and 45% kerosene as a cost-reducing factor.A preferred additive is:______________________________________ Cupric sulfate .02% Picric acid 1.54% Methanol 35% Isopropyl alcohol 15% Toluene 48.3% Nitrobenzene .8% Primene 81R .05% ______________________________________
Abstract:
Middle distillate fuel additives, especially diesel fuel additives, are disclosed which improve one or more cold flow properties of said fuel such as cetane, pour point, wax formation and anti-icing characteristics. The additives comprise a cold flow improver, preferably a vinyl acetate-ethylene copolymer, a cetane improver comprising paraffinic nitrate or a mixture of nitrates, an anti-icer comprising an aliphatic alcohol or a cyclic aliphatic alcohol having from 1 to 6 carbon atoms or mixtures thereof and an oil soluble aromatic solvent.
Abstract:
A family of liquid hydrocarbon motor fuel additives known as polynitro alkyls having the general formula R.sub.1 --C(NO.sub.2).sub.2 --R.sub.2 have been found to enhance the overall combustion characteristics of motor fuels by increasing combustion efficiency and reducing undesirable combustion by-products.
Abstract:
An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, (2) an ignition accelerator and (3) a wear inhibiting amount of a dimerized unsaturated fatty acid and an ester of a phosphorus acid.
Abstract:
This invention relates to the inhibition of microbial growth in liquid distillate hydrocarbon fuels and more particularly to the use of halonitro alcohols as microbicides which effectively inhibit microbial growth in liquid distillate hydrocarbon fuels when incorporated therein at low concentrations.
Abstract:
An improved liquid diesel fuel for diesel engines is made by incorporating at least 0.003% by weight of a mixture of an iron salt of an aromatic nitro acid and a nitroaliphatic compound having one to four carbon atoms, into the diesel fuel. The weight ratio of the aromatic nitro acid salt to the nitroaliphatic compound ranges from 1:10 to 1:100. The additive, when added to diesel fuel, (1) substantially eliminates hard carbon deposits from the valve and exhaust systems of diesel engines, thereby improving the efficiency of the engines and decreasing overhaul expense, (2) reduces air pollutants such as oxides of sulphur and nitrogen, and virtually eliminates carbon monoxide from diesel exhausts and (3) reduces or substantially eliminates slime deposits which form during diesel fuel storage.
Abstract:
Materials consisting essentially of hydrocarbons with at least two straight chain alkyl groups are useful as wax crystal modifiers in petroleum oils, particularly middle distillate fuel oils such as heating oils and diesel fuels. These materials can be prepared by dimerizing .alpha.-olefins, which dimers can be used per se, or can be further derivatized, e.g. polymerized, alkylated on to an aromatic molecule, etc.
Abstract:
A method of preparing a nitroketonized amide by contacting an acid amide of the formula:
WHERE R1 is an alkenyl group of from 4 to 40 carbon atoms, where R2 and R3 alternately represent hydrogen and an alkenoyl group of from 4 to 40 carbon atoms, with dinitrogen tetroxide and oxygen, at mole ratios of acid amide to dinitrogen tetroxide to oxygen of from 1:2:2 to 1:4:60.
Abstract:
A method for preparing amides by reacting a vicinal nitroketone with ammonia, a primary amine or a secondary amine at a temperature of from about 60* to about 130*C. The amides so prepared are useful as foam stabilizers, waterproofing agents, rust inhibitors, fuel oil additives, antistatic compounds, viscosity controllers, cosmetic components and high-temperature solvents.
