摘要:
Provided herein are estolide base oils and oligomeric compounds prepared from processes that include cross metathesis. Exemplary processes include the preparation of terminally-unsaturated fatty acids by cross metathesis, and the subsequent oligomerization of terminally-unsaturated fatty acids to provide estolide compounds, such as the process set forth below:

摘要:
A lubricant or process fluid composition having excellent low temperature properties comprises a capped estolide ester, a polyalphaolefin, a synthetic ester and/or polyalkylene glycol, and a pour point depressant. The combination of the three base oils plus the pour point depressant produces a synergistic composition that may have a pour point less than −15° C., preferably less than −35° C., while also having more than 50 percent by weight renewable carbons and being economical and effective in a wide variety of applications.
摘要:
Provided is a lubricating oil composition for a refrigerator which uses a base oil including as the main component at least one kind of oxygen-containing compounds selected from polyoxyalkylene glycols, polyvinyl ethers, copolymers of poly(oxy)alkylene glycols or monoethers thereof and polyvinyl ethers, polyol esters, and polycarbonates. The lubricating oil composition for a refrigerator is used for a refrigerator that uses, as a refrigerant, a fluorine-containing organic compound, which is a refrigerant applicable to current car air conditioner systems or the like and has a specific polar structure, and has favorable sealing property, a low coefficient of friction factor in a sliding part, and excellent stability as well as excellent compatibility with the refrigerant.
摘要:
Provided herein are compounds, including those of the Formula II in which n is an integer equal to or greater than 1; R2, is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R3, and R4, independently for each occurrence, are selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched. Also provided are compositions containing such compounds and methods of making both compounds and compositions thereof.
摘要:
This invention relates to functionalized monomers which are reacted with an enophilic reagent (e.g., maleic anhydride) to form an enophilic reagent modified functionalized monomer. The enophilic reagent modified functionalized monomer may be further reacted with one or more additional reagents (e.g., oxygen-containing reagents, nitrogen-containing reagents, metals or metal compounds). The invention relates to base oils which may comprise functional base oils. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food products, etc.).
摘要:
An object of the present invention is to provide a refrigeration cycle apparatus having a compressor that is not easily heated to high temperature by sliding heat and thus higher in reliability.Provided is a refrigeration cycle apparatus having a cost-effective compressor in the configuration in which a piston 9 eccentrically revolving, as driven by a shaft 4, is placed in a cylinder 6 and the circular terminal region 10a of a vane 10 partitioning the cylinder 6 into a suction chamber 12 and a compression chamber 13 is connected slidably to the external surface of the piston 9 in surface contact, which can reduce the sliding heat and is thus resistant to deterioration in reliability by reaction of the operating refrigerant.
摘要:
The present invention relates to a lubricant composition. The present invention more particularly relates to a fully miscible lubricant composition that comprise a polyether and a renewable raw material such as an unsaturated seed or vegetable oil.
