Abstract: The present invention relates to a process for the synthesis of diacetyl epoxy glyceryl oleate, comprising the steps of: a) esterification of glycerol and oleic acid at 115-190°C for 1.5-4.5 hours in the presence of an esterification catalyst to obtain glyceryl monooleate; b) acetylation of glyceryl monooleate and an acetylating reagent at 90-160°C for 2-10 hours in the presence of an acetylation catalyst to obtain diacetyl glyceryl oleate; c) epoxidation of diacetyl glyceryl oleate and hydrogen peroxide at 60-80°C for 2-4 hours in the presence of an epoxidation catalyst and a weak acid to obtain diacetyl epoxy glyceryl oleate. The prepared diacetyl epoxy glyceryl oleate can be used as plasticizer in plastics, with the advantages of improved stability, good flowability, and high compatibility with plastics.

Abstract: Methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing a natural oil with an acid and a peroxide. Residual acid in the epoxidized natural oil is not neutralized, such as with a base, prior to esterification to produce the epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizers, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2/100 g of epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

Abstract: The present invention relates to a novel process for epoxidation of vegetable oils. The epoxidation process is characterised in that vegetable oil is reacted with a suitable salt in a pH-controlled aqueous solution in the presence of a ketone, however in the absence of a phase-transfer catalyst.

Abstract: A process is disclosed for preparing epoxide group-containing organic compounds. Monounsaturated or polyunsaturated organic compounds are oxidised with an aqueous hydrogen peroxide solution in the presence of carboxylic acids. The process is characterised in that 0.01 to 0.5 % by weight of an anti-oxidising agent, with respect to the amount of unsaturated compounds, is added to the reaction mixture, and in that inert gas is made to flow during the reaction through the reaction vessel. This process is easy to implement and produces high yields of epoxide group-containing organic compounds.
