  • Patent number: 4208190
    Abstract: An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, and (2) a wear inhibiting amount of a straight chain aliphatic primary amine, e.g. oleyl amine. Optionally, said fuel composition may also contain an ignition accelerator such as an organic nitrate.It has recently been disclosed in Brazilian Patent Application No. P17700392 that alcohols, such as methanol and ethanol, can be substituted for conventional petroleum derived diesel fuels for burning in diesel engines, when used in combination with an ignition accelerator, such as ethyl nitrate or nitrite. Reportedly, the addition of alkyl nitrate or nitrite accelerators to the alcohol achieves a level of auto-ignition sufficient to operate in diesel engines.

  • Patent number: 4206172
    Abstract: The present invention is drawn to ethylene polyamines in combination with certain alkanolamines as cold-end additives. More specifically, it has been discovered that if these additives are fed to the moving combustion gases of a combustion system which uses sulfur containing fuel and upstream of cold-end surfaces to be treated, the additive will travel along with the gases as vapor and/or liquid droplets and deposit on the cold-end surfaces. As a result, the amount of sulfuric acid corrosion of metallic cold-end surfaces is reduced.

  • Patent number: 4196016
    Abstract: A method of salt grinding pigments wherein the material to be ground is milled with an inorganic salt, an organic conditioner, and larger particles such as balls or nails for comminuting the pigment to the desired state of subdivision and is subsequently recovered from the ground mass wherein the mass is treated after grinding with an organic liquid which is a solvent for the organic conditioner but which is inert to the pigment and to the inorganic grinding aid. The dispersion resulting is then centrifuged to remove solids constituting over-size pigment and inorganic grinding aid without separating the dispersed pigment particles of desired state of subdivision. The sediment is removed from the liquid dispersion of pigments and the liquid is subsequently separated from the dispersed pigment as by filtering or other appropriate means.

  • Patent number: 4194886
    Abstract: Condensation products made by reacting an alpha-haloalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The number of carbon atoms in the aromatic hydrocarbyl compound's substituents are each about 25 while the haloalkyl group contains from one to about 36 carbons. The acid or nitrile reactant usually contains three to about forty carbons. Products made from halomethyl alkyl-substituted phenols and .alpha.,.beta.-olefinic diacid derivatives such as maleic anhydride are particularly useful. Similarly useful products can be made from these condensation products by further reacting their acid, acid derivative or nitrile groups with alcohols, polyols, monoamines, polyamines, metal salts or metals.

  • Patent number: 4191742
    Abstract: A method for producing precipitated silica products having a unique combination of physical and chemical properties is disclosed. The products are produced by acidulating a solution of an alkali metal silicate with an acid under carefully controlled precipitation conditions. In accordance with the method, at least a portion of the alkali metal silicate solution theoretically required to react with said acid is initially charged to the reaction vessel. Thereafter, the remaining silicate solution and the acid are simultaneously added to the reaction vessel in a manner to control the alkalinity of the reaction medium. By controlling the percent of the silicate solution initially charged to the reaction vessel, silicas having predetermined properties can be obtained. Properties of the products include low wet cake moisture content, low structure, low oil absorption, high abrasiveness, and low void volume. The products can be used as abrasive and polishing agents in dentifrice compositions.
