  • Patent number: 5650097
    Abstract: Steel anticorrosion and lubricity composition consisting essentially of (a) a surfactant; (b) at least one neutralized alkyl phosphate in a surfactant:phosphate weight ratio in the range between 10:1 to 1:10, said phosphate having the general formula:(RO).sub.m --P--(O)--(OH).sub.nwherein R is an alkyl group having 4 to 20 carbon atoms; m is 1 or 2, and n is 3m; and optionally (c) 5 to 40 weight percent, based on the combined weight of said surfactant and said phosphate, of at least one carboxylic acid which has both a hydrophilic and a hydrophobic portion.

  • Patent number: 5587355
    Abstract: This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additive of the present invention is thiophene carboxylic acid (TCA) derivatives, preferably TCA per se or thiophene C.sub.1 -C.sub.4 alkanoic acid and the P-containing additive is one or more amine phosphate(s). The turbo oil composition consisting of the dual P/S additives of the present invention achieves an excellent load-carrying capacity, which is better than or equivalent to that obtained when each additive was used alone at a higher treat rate than the total P/S additive combination treat rate, and this lower concentration requirement of the P and S additive allows the turbo oil composition to meet or exceed US Navy MIL-L-23699 requirements including Oxidation and Corrosion Stability and Si seal compatibility.

  • Patent number: 5578557
    Abstract: A food grade compressor oil for use in a high pressure compressor includes a base oil, an N-acyl derivative of the amino acid sarcosine, an imidazoline, and an amine-phosphate. Each of the three additives comprises no more than 0.5% by weight of the oil composition, and results in high lubricity and very low corrosion even when water is present in the oil. The compressor oil may also include polybutene which serves as a thickener, and an antioxidant. The compressor oil of this invention is particularly well suited for use in a hypercompressor used in the manufacture of polyethylene.

  • Patent number: 5552068
    Abstract: A lubricant oil composition having balanced antiwear/extreme pressure and stability properties while providing friction reduction which comprises:(1) a major amount of a lubricating oil basestock; and(2) a minor amount of an amine phosphate salt of the formula: ##STR1## where R.sub.1 is C.sub.9 to C.sub.22, R.sub.2 and R.sub.3 are each independently C.sub.1 to C.sub.4 hydrocarbyl, R.sub.4 is c.sub.10 to c.sub.20 hydrocarbyl, and R.sub.5 is hydrogen to c.sub.10 to c.sub.20 hydrocarbyl; wherein the amine phosphate salt is soluble in the lubricant oil basestock at 25C, is a liquid at 25C, and the ratio of gram-atomic-equivalents of amine to phosphate in said salt is from about 1.0 to 1.2.
