摘要:
Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.

A method for producing a triglyceride including fatty acids with vicinal diesters: (a) providing a triglyceride including fatty acids with epoxide groups; (b) reacting the epoxide groups with carboxylic acid salts under basic conditions to produce a triglyceride including fatty acids with vicinal ester/alkoxides; (c) protonating the vicinal ester/alkoxides to produce a triglyceride including fatty acids with vicinal ester/alcohols; and (d) reacting the vicinal ester/alcohols with carboxylic acids under acidic conditions to produce a triglyceride including fatty acids with vicinal diesters.
摘要:
A method including substituting an atmosphere in a space, in which a sliding surface formed of a metal or a ceramic material, and a slid surface are disposed, with a gas atmosphere containing a hydroxyl group-containing compound and at least one of hydrogen and nitrogen, and relatively sliding the sliding surface against the slid surface by a Hertzian contact stress of 1.0 GPa or more in the space under the gas atmosphere containing the hydroxyl group-containing compound at least one of hydrogen and nitrogen. As a result, it is possible to form, on the sliding surface, a low-friction coating that stably exhibits a significantly low friction coefficient, for example, of 10−4 order (less than 0.001).

Methods are provided for producing Group II base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group II base stocks can have a viscosity at 100° C. and/or a viscosity at 40° C. that is greater than the corresponding viscosity for a conventional Group II base stock. Additionally, the resulting Group II base stocks can have one or more properties that are indicative of a high quality base stock.
摘要:
A bio-organic composition includes residues of a fatty acid glyceride-containing composition, residues of a first epoxide or glycol, and the residues of a second epoxide. The fatty acid glyceride-containing composition is characterized by the viscosity at room temperature. The first epoxide or glycol and second epoxides are present in a sufficient amount that the room temperature viscosity of the bio-organic composition is lower than the room temperature viscosity of the vegetable oil prior to formulation and/or the first epoxide or glycol and second epoxides are present in a sufficient amount that the pour point of the bio-organic composition is lower than the pour point of the fatty acid glyceride-containing composition prior to formulation.
摘要:
A method for forming an anti-stiction coating on a surface of a semiconductor device is provided. Using atomic layer deposition (ALD) processes to activate surface prior to anti-stiction coating deposition, anti-stiction coating having strong chemical bonding to the surface is obtained.
摘要:
Provided are lube base stocks produced from renewable biological sources with improved low temperature properties. In one form, the lube base stock includes from 10 to 35 wt. % paraffins, 40 to 70 wt. % 1-ring naphthenes, and 0 to 40 wt. % combined 2-ring naphthenes and aromatics, and has a ratio of 1-ring naphthenes to paraffins from 1.8 to 5.0, and a Viscosity Index of from 100 to 160. The lube base stock has a 14C level ranging from 2 to 101% of the modern day 14C level in the atmosphere, and yields a CCS ratio (Cold Crank Simulator (CCS) viscosity to the predicted CCS viscosity by Walther equation) of less than or equal to 0.85 at −35° C. The base stocks are useful as in formulated lubricant compositions requiring improved low temperature properties.
摘要:
The present invention relates to lubricant base oils comprising paraffinic hydrocarbon components having optimized branching. These lubricant base oils comprising paraffinic hydrocarbon components with optimized branching have low amounts of branching overall with the branching concentrated toward the center of the lubricant base oil molecules. The present invention also relates to processes of producing these lubricant base oils from waxy feeds and commercial finished lubricants comprising these lubricant base oils.
