Claims39
A method for improving water dispersability of a vegetable oil comprising transesterifying said vegetable oil with triethanolamine or ethoxylated triethanolamine to form partial esters, wherein said vegetable oil has a monounsaturated fatty acid content of at least 70%, and wherein said partial esters comprise at least 70 wt % of the reaction products.
An oil comprising compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 70% of said aliphatic hydrocarbyl moieties are monounsaturated, wherein at least 50 weight % of said compounds of formula A and B contain a hydroxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- and wherein X is 0 or 1.
A metalworking fluid concentrate comprising an oil, a surfactant, and one or more additives selected from the group consisting of a biocidal agent, a corrosion inhibitor, an extreme pressure additive, an antiwear additive, an antirust additive, and an antifoam additive, wherein said oil comprises compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 50 weight % of said compounds of formula A and B contain a h droxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- and wherein X is 0 or 1.
A method of producing a transesterified oil comprising transesterifying a triacylglycerol oil and triethanolamine or ethoxylated triethanolamine to produce said transesterified oil, wherein said transesterified oil comprises compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 70% of said aliphatic hydrocarbyl moieties are monounsaturated, wherein at least 50 weight % of said compounds of formula A and B contain a hydroxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- and wherein X is 0 or 1.
An industrial oil formulation comprising an oil and one or more additives selected from the group consisting of antioxidants, anti-rust additives, anti-wear additives, pour point depressants, viscosity index improvers, and anti-foam additives, wherein said oil comprises compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 50 weight % of said compounds of formula A and B contain a hydroxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- and wherein X is 0 or 1.
A method for improving water dispersability of a vegetable oil comprising transesterifying said vegetable oil with triethanolamine or ethoxylated triethanolamine to form partial esters, wherein the molar ratio of triethanolamine or ethoxylated triethanolamine to said vegetable oil is about 1:1 to about 3:1.
A method for improving water dispersability of a vegetable oil comprising transesterifying said vegetable oil with triethanolamine or ethoxylated triethanolamine to form partial esters, wherein the molar ratio of triethanolamine or ethoxylated triethanolamine to said vegetable oil is about 1:1 to about 5:1.
An oil comprising compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 50 weight % of said compounds of formula A and B contain a hydroxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- wherein X is 0 or 1, and wherein the molar ratio of compounds of formula A to formula B is about 1:1 to about 1:3.
An oil comprising compounds of formula A and formula B:
- wherein R1-R6 are a hydroxyl moiety or
- wherein Y is an aliphatic hydrocarbyl moiety having three to 23 carbons atoms, wherein at least 50 weight % of said compounds of formula A and B contain a hydroxyl moiety and at least 50 weight % of said compounds of formula A and B contain
- wherein X is 0 or 1, and wherein the molar ratio of compounds of formula A to formula B is about 1:1 to about 1:5.
