Method for preparing fatty acid esters from seeds or fruits

A method for producing ortho-alkylated phenols comprising reacting phenols represented by the general formula (1) with monohydric or dihydric alcohol in the presence of germanium oxide under conditions in which said alcohol is in the supercritical condition, wherein each of R , R , R , R and R independently represents a hydrogen atom, or a linear or branched alkyl group having 1 to 10 carbon atoms.

Method for producing ortho-alkylated phenols

A process for producing hydrogen peroxide which comprises reacting hydrogen and oxygen in a reaction medium containing a halide of platinum group metal. The process is far simplified and the produced amount of hydrogen peroxide per the halide of platinum group metal is large.

Process for producing hydrogen peroxide

Disclosed is a process for producing an epoxidized product of olefins, which comprises oxidizing olefins in the presence of an oxidizing catalyst, using an alcohol medium solution of hydrogen peroxide produced by catalytically reacting hydrogen with oxygen in an alcohol medium. According to the present invention, an epoxidized product of olefins can be produced by using an alcohol medium solution of hydrogen peroxide in high selectivity without requiring an aqueous hydrogen peroxide solution of high concentration and producing a large amount of by-products.
