The present invention relates to light-colored corn wax oxides, to a process for their preparation, and to their use for agricultural or forestry purposes, as additives in plastic processing, in care products, in printing inks and / or in paints, and to saponified or esterified corn wax oxides prepared by saponification or esterification of the said corn wax oxides.

A method can include receiving an oxygenate sample, fractioning the oxygenate sample into one or more fractions, and separating the fractions (e.g. using FAME fractionation, FAEE fractionation, crystallization, solvent extraction, or other similar methods). The fractions can optionally be separated independently. The method can optionally include esterifying carboxylic acids separated from the fractions with glycerol and deodorizing the glycerides.

The invention relates to partially saponified rice bran wax oxidates, to a process for the production of these products and to their use for agricultural or forestry purposes, as an additive in plastics processing, in care products, in printing inks and / or in paints.

A method can include oxidizing hydrocarbons (and optionally oxygenates with oxygenation states less than carboxylic acids such as alcohols, aldehydes, etc.), separating the oxygenated hydrocarbons into saponifiable species and nonsaponifiable species, and treating the saponifiable species (e.g., heat treating, hydrogenation, etc. such as to reduce unsaturated bonds to saturated bonds, to convert oxygenates with greater degrees of oxygenation than monocarboxylic acids into monocarboxylic acids, etc.).

Various aspects provide a method for making a polymerized vegetable oil. The method includes a) passing air through a heated starting vegetable oil. The starting vegetable oil is heated to a temperature in a range of from 100 °C to 200 °C to form a blown polymerized vegetable oil having a viscosity higher than a viscosity of the starting vegetable oil. The method further includes b) stripping the blown polymerized vegetable oil of a) with steam or a mixture comprising nitrogen (N2) and steam, the steam or mixture of steam and nitrogen, the blown polymerized vegetable oil being at a temperature in a range of from 220 °C to 260 °C to form a stripped polymerized vegetable oil having a flash point, fire point, or both that are each higher than a flash point, fire point, or both of the blown polymerized vegetable oil at a).

This invention relates to a method for improving the oxidative stability of edible vegetable oils in application scenarios, specifically in the field of oil antioxidant technology. The method involves determining the types and contents of unsaturated fatty acids at different spatial positions of triglyceride molecules in edible vegetable oils, calculating the oxidation rate constants of different types of unsaturated fatty acids at different spatial positions in application scenarios, calculating the inhibition value of the oxidation rate constants of unsaturated fatty acids at corresponding positions of rosemary extract, calculating the total amount of rosemary extract to be added, and adding the obtained total amount of rosemary extract to the edible vegetable oil. This invention addresses the practical application scenarios of edible vegetable oils after opening. Based on the types and quantities of unsaturated fatty acids at different spatial positions of triglyceride molecules in edible vegetable oils, it precisely adds the natural, heat-resistant antioxidant rosemary extract through calculation, achieving high-quality preservation of edible vegetable oils in practical application scenarios.

The invention discloses biomass lubricating grease and a preparation method thereof, and belongs to the technical field of lubricating materials, the biomass lubricating grease comprises the following components: base oil, a thickening agent, modified lignin and an additive; the base oil is prepared from kitchen waste separated refined oil and modified vegetable oil; the modified vegetable oil is prepared from natural vegetable oil through transesterification, epoxidation and etherification in sequence; the thickening agent comprises a metallic soap base and modified lignin; the modified lignin is silane coupling agent modified lignin. Compared with the traditional chain lubricating grease, the biomass lubricating grease provided by the invention is more energy-saving and environment-friendly, and is beneficial to waste utilization; the metal soap base and the modified lignin which are high in biodegradability are adopted in the thickening agent, so that the thickening agent is easy to biodegrade and cannot cause long-term influence on the environment. In addition, the adopted base oil is good in low-temperature performance, and the metal soap base and the modified lignin are matched, so that normal operation of the chain in high and low temperature environments can be met.

This invention relates to a method for producing highly ozonated fatty acids by subjecting extra virgin sunflower oil containing a high concentration of polyunsaturated fatty acids to high ozonolysis. Similarly, this invention relates to the highly ozonated fatty acids produced by said method and their cosmetic and medical uses, particularly due to their repairing effects on skin damage.

The invention relates to partially saponified rice bran wax oxidates, to a process for the production of these products and to their use for agriculture or forestry purposes, as an additive in plastics processing, in care products, in printing inks and / or in paints.

Disclosed herein is a method for preparing ethoxylated glycerol esters (formula (I)) by reacting ethylene oxide with triglycerides (formula (II)) using a calcium catalyst. The catalyst is formed from calcium hydroxide (A), a C3-C40 carboxylic acid (B) (formula (III)), and a strong acid (AC) (pKa≤3) derived from sulfur or phosphorus oxides. In formulae (I) and (II), R1-R3 are C7-C24 alkyl chains, with ethoxylation units (m+n+o) averaging>5. In formula (III), R4 is selected from saturated or unsaturated, linear or branched C1-C30 alkyl chains, and R5, R6, R7, and R8 are hydrogen. The calcium hydroxide: carboxylic acid ratio (A):(B) is 1:1-1:5, while calcium hydroxide: strong acid ratio (A):(AC) is 5:1-1:1.
