The present invention provides a method for producing an epoxy compound by a reaction of an olefin compound with hydrogen peroxide, wherein the epoxy compound is stably and safely produced using a hydrogen peroxide stabilizer for reducing an oxygen gas generated from hydrogen peroxide. A method for producing an epoxy compound by a reaction of an olefin compound with hydrogen peroxide, wherein the reaction is carried out in the presence of an organophosphorus compound in such a reaction medium that the pH is maintained within a range of more than 7.5 and less than 12.0. The olefin compound may be 1,3,5-tris-(alkenyl)-isocyanurate. The alkenyl group in the olefin compound may be 3-butenyl group, 4-pentenyl group, 5-hexenyl group, 6-heptenyl group, or 7-octenyl group. The epoxy compound may be 1,3,5-tris-(epoxyalkyl)-isocyanurate. The reaction medium may be such a reaction medium that the pH is maintained within a range of 8.0 to 10.5.

Method for producing epoxy compound containing hydrogen peroxide stabilizer

There is provided a method for producing an epoxy compound having an epoxy ring bonded to a triazinetrione ring via a long chain alkylene group, an olefin compound having a specific structure is used to efficiently obtain an epoxy compound of which an olefin moiety is epoxidized in high yield. A method for producing an epoxy compound of Formula (2): including reacting a triolefin compound of the following Formula (1): (In the above-mentioned Formulae, Rto Rare each independently a hydrogen atom or a methyl group; and n1 to n3 are each independently an integer of 1 to 4) with hydrogen peroxide, a nitrile compound, and an alkaline substance in a solvent. The nitrile compound is an aliphatic nitrile compound or an aromatic nitrile compound. The alkaline substance is phosphate, carbonate, or an alkaline metal hydroxide.

Method for producing epoxy compound

There is provided a practical method for preparing lipopeptide compounds, which method is capable of inexpensive mass production without requiring complicated operations. The lipopeptide compound of formula (3): is produced by reacting an ester compound of formula (1): with an &#x3b1;-amino acid compound of formula (2): in the presence of a base and within a solvent containing a nonpolar organic solvent.
