Reduced color epoxidized fatty acid esters are provided which may be used as primary plasticizers for PVC, in replacement of phthalate plasticizers. The reduced color epoxidized fatty acid esters are prepared from natural fats or oils by transesterification and interesterification processes, whereby through the use of borohydride, materials having Pt&#x2014;Co colors according to ASTM D1209 on the order of 50 and lower are possible.

Reduced color epoxidized esters from epoxidized natural fats and oils

Processes are described for making epoxidized fatty acid esters from epoxidized natural fats and oils, wherein low moisture fats and oils are identified and selected or made and used in a transesterification process. The products undergo phase separation, and reduced molar excesses of alcohol may be employed compared to processes not employing a low moisture feedstock.

Making epoxidized esters from epoxidized natural fats and oils

Presently disclosed are high purity unsaturated fatty acid esters with an ester moiety characterized by having from five to seven members in a ring structure, which esters when epoxidized find particular utility as primary plasticizers in flexible polyvinyl halide applications. Also disclosed are processes for making the high purity esters.

Processes for making high purity renewable source-based plasticizers and products made therefrom

This invention relates to a composition comprising, consisting of or alternatively consisting essentially of a stabilized furfural or glycol ester of a vegetable oil fatty acid and an antioxidant such as butylated hydroxy toluene. This invention also relates to latex film-forming compositions containing stabilized furfural or glycol esters, such as a stabilized propylene glycol monoester (PGME) mixture. This invention is also directed to methods of stabilizing furfural or glycol esters of a vegetable fatty acid by contacting the esters with an antioxidant such as butylated hydroxy toluene. This invention also includes methods of preparing film-forming compositions comprising a stabilized furfural or glycol ester, such as the stabilized PGME mixture disclosed herein.

Stabilized ester compositions and their use in film-forming compositions

The present invention is directed to a process of producing polyol esters possessing desirable composition and color. Preferably, such a process does not require molecular distillations or decoloration steps to yield a light-colored polyol ester composition. Materials that are dark in color are often produced during the esterification of polyols with vegetable oil fatty acids. It has been discovered that the present process yields the desired ester products that are light in color. The present process comprises an esterification of a polyol, such as propylene glycol, and a fatty acid ester, such as a vegetable oil fatty acid methyl ester, in the presence of a catalyst and borohydride, wherein a polyol ester having a Lovibond color below about 0.6 Red and below about 1.5 Yellow is produced.

Methods for the preparation of polyol esters that are light in color

A method for producing 1,3-diglyceride oils from triglyceride containing oils is disclosed. The method uses alkali metal salts or alkali earth metal salts of mono-carboxylic or di-carboxylic acids to drive glycerolysis under conditions such that commercial, food-quality 1,3-diglyceride oils are produced.

Chemical process for the production of 1,3-diglyceride oils

The present invention is directed to a latex paint composition comprising polyunsaturated fatty acid containing additives derived from vegetable oils. In preferred embodiments, traditional water soluble additives such as thickeners, surfactants and dispersants are replaced with polyunsaturated fatty acid derivatives, adducts or polyunsaturated fatty acid containing polymers. The polyunsaturated fatty acid containing additives reduce or eliminate the need for traditional water soluble additives that lower the water resistance of the dry paint film. Additionally, the polyunsaturated fatty acid moieties are capable of oxidative crosslinking during the curing process, forming a dry paint film that is more durable and water-resistant than traditional latex paint compositions.

Polyunsaturated fatty acids as part of reactive structures for latex paints: thickeners, surfactants, and dispersants

A process of producing a light-colored, high-monoester mixture from a polyol and an oil is provided wherein the process eliminates the use of organic solvents, multiple water washings and/or molecular distillation. The reactants, a polyol and an oil, described herein, condense in the presence of a catalyst, described herein, at a temperature range from about 180&deg; C. to about 280&deg; C. under an inert atmosphere or the vapor pressure of the polyol with a pressure of about 0 to about 500 psig to yield a monoester mixture possessing a desirable monoester composition and color. The present process yields a final product similar to that of processes which require the use of solvents, multiple water washings and/or molecular distillation.

A modified vegetable protein binder produced by and a method of producing a modified vegetable protein binder for paper coatings by bleaching a vegetable protein extract with an oxidizing agent and a magnesium compound to provide a bleached vegetable protein material and then modifying the bleached vegetable protein. The modification is generally hydrolyzing the bleached vegetable protein and when desired, also carboxylating the bleached vegetable protein.

Method of producing protein products for bright paper coating

A method of producing a modified vegetable protein binder for paper coatings having improved whiteness, brightness and strength wherein a vegetable protein material is oxidized with an oxidizing agent and a low level of magnesium compound.
