The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Disclosed are refrigerants comprising at least about 97% by weight of a blend of three compounds, said blend consisting of:

from about 40% by weight to about 49% by weight difluoromethane (HFC-32),
from about 6% by weight to about 12% by weight pentafluoroethane (HFC-125),
from about 33% by weight to about 40% by weight trifluoroiodomethane (CF.sub.3I); and
from about 2% by weight to about 12% by weight of trans 1,3,3,3-tetrafluoropropene (trans HFO-1234ze), wherein the percentages are based on the total weight of the three compounds in the blend, and systems and method using same.

Provided herein are olefinic feedstocks derived from conjugated hydrocarbon terpenes (e.g., C.sub.10-C.sub.30 terpenes), methods for making the same, and methods for their use.

Bottlebrush poly(alpha olefin)s of high carbon number, greater than 12 such as poly(octadecene), are used as a thickener for a synthetic base oil grease lubricant that is based on oligomerized alpha olefin with carbon number from 7 to 12, such as oligo(decene). Dispersion aids are not required in the present lubricants because poly(octadecene) can be dissolved in oligo(decene). The lubricant is a solid grease formed by percolation/network of the poly(octadecene) crystals, at a sufficient concentration, after the crystallization of poly(octadecene), and water resistant having oxidation/high temperature stability.

The invention discloses synergistic combinations of surfactant blends and cleaning compositions employing the same. In certain embodiments a surfactant system is disclosed which includes an extended anionic surfactant with novel linker surfactants including one or more of an alkyl glycerol ether, an ethoxylated alkyl glycerol ether, an alcohol ethoxylate and/or a Gemini surfactant. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a tetrafluoropropene and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

A composition including one or more diester compounds represented by the formula as defined herein. The composition has a viscosity (Kv.sub.100) from about 1 cSt to about 10 cSt at 100 C. as determined by ASTM D445, a viscosity index (VI) from about 100 to about 300 as determined by ASTM D2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D5800. A process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of thermal and oxidative stability, solubility and dispersancy of polar additives, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the composition.

The present invention relates to a mixed complex soap based grease composition comprising a lubricating base oil; a saponifiable material; a metal oxide; an alkali/alkaline metal hydroxide; and a complexing acid. The present invention also discloses a single-step, open kettle, energy-efficient process which gives smooth textured zinc-alkali/alkaline earth metal mixed complex grease composition with relatively low thickener content while still maintaining desired consistency. The zinc-alkali/alkaline earth metal mixed complex grease composition is tailor made to have dropping point in a range of 180? C. to 300? C. comparable to lithium and lithium complex grease composition, have inherent oxidation stability, extreme pressure, anti-wear properties, and water resistance properties. The zinc-alkali/alkaline earth metal mixed complex grease composition shows excellent additive response good mechanical stability, low temperature properties, pumpability, and corrosion resistance.

This invention relates to methods to reduce abnormal combustion events in the operation of an internal combustion engine comprising using a lubricating oil composition comprising/resulting from the admixing of: (i) base oil, (ii) detergent, preferably providing at least 800 ppm Mg and less than 500 ppm Ca; and (iii) abnormal combustion event inhibitor compound(s), preferably comprising at least one phosphorus containing compound providing greater than 0.12 mass % phosphorus; wherein: 1) the lubricating oil composition is a SAE 10W-X, SAE 5W-X or SAE 0W-X blend, where X is 8, 12, 16, 20, or 30; and 2) when the lubricating oil composition is combined with an 88 octane reference fuel, the combination completes at least 1 iteration of 175,000 cycles per iteration, as determined by Sequence IX Test, ASTM D829.
