The present invention relates to the field of methods for purifying fatty acid ethyl esters. According to the present invention, a method for obtaining a ?3 fatty acid ethyl ester, such as EPA and DHA, each as a high purity product at a high yield is provided. In the method according to the present invention, a raw material fat including EPA and DHA is treated with a lipolytic enzyme and ethyl-esterification is performed as needed; the treated substance is fractionated into a glyceride fraction and a free fatty acid fraction; a fraction comprising more EPA ester and a fraction comprising DHA ester are obtained from the respective fractions; the fraction comprising more EPA ester is purified to prepare a high-purity EPA ester; and the fraction comprising more DHA ester is purified to prepare a high-purity DHA ester.

Dicarboxylic diesters are disclosed having the formula (I):

##STR00001##

wherein n is 3, and X is a C.sub.2 alkylene or a C.sub.2 alkenylene group. Such dicarboxylic diesters are useful for inhibiting the methane production in ruminants.

Ecofriendly emulsifier synthesis from esterified waste vegetable oil for wellbore drilling fluids is described. A raw material waste vegetable oil is esterified to produce a methyl ester of the raw material waste vegetable oil. A caustic soda solution is added to the methyl ester resulting in a mixture. The mixture is thermally treated. A pH of the mixture is adjusted resulting in formation of an aqueous phase and a non-aqueous phase. The aqueous phase is separated from the non-aqueous phase.

A fiber reaction process whereby reactive components contained in immiscible streams are brought into contact to effect chemical reactions and separations. The conduit reactor utilized contains wettable fibers onto which one stream is substantially constrained and a second stream is flowed over to continuously create a new interface there between to efficiently bring about contact of the reactive species and thus promote reactions thereof or extractions thereby. Co-solvents and phase transfer catalysts may be employed to facilitate the process.

The present invention relates to methods of producing industrial products from plant lipids, particularly from vegetative parts of plants. In particular, the present invention provides oil products such as biodiesel and synthetic diesel and processes for producing these, as well as plants having an increased level of one or more non-polar lipids such as triacylglycerols and an increased total non-polar lipid content. In one particular embodiment, the present invention relates to combinations of modifications in two or more of lipid handling enzymes, oil body proteins, decreased lipid catabolic enzymes and/or transcription factors regulating lipid biosynthesis to increase the level of one or more non-polar lipids and/or the total non-polar lipid content and/or mono-unsaturated fatty acid content in plants or any part thereof. In an embodiment, the present invention relates to a process for extracting lipids. In another embodiment, the lipid is converted to one or more hydrocarbon products in harvested plant vegetative parts to produce alkyl esters of the fatty acids which are suitable for use as a renewable biodiesel fuel.
