    Abstract: PURPOSE:To provide a method for fractionating a sucrose fatty acid ester having a specific composition from a reaction mixture of sucrose fatty acid esters by a simple operation without using an organic solvent. CONSTITUTION:Sucrose fatty acid esters composed of a mixture of [SME], [SDE] and [SPE] ([SME] is a sucrose fatty acid ester having 1 ester exchange degree, [SDE] is a sucrose fatty acid ester having 2 ester exchange degree and [SPE] is a sucrose fatty 7 acid ester having >=3 ester exchange degree) are mixed with fats and oils under heating and the prepared heated mixture is incorporated with water to extract a sucrose fatty acid ester having high [SME] content. The prepared water phase and the oil phase are separated to give a sucrose fatty acid ester having high [SME] content and sucrose fatty acid esters having high [SDE] and [SPE] contents.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for purification by which a sufficiently deodorized glyceryl ether can efficiently be obtained.
    SOLUTION: The method for purifying the glyceryl ether is a method for purification comprising using a distillation column having a structure in which the central part of the column is divided into two distillation parts. The method for purification is carried out as follows. The crude glyceryl ether containing the specific glyceryl ether and a lower-boiling component and a high-boiling component having a different boiling point from that of the glyceryl ether as impurities is fed to one of the divided distillation parts in the central part of the column and separated into a fraction (a) containing the low-boiling component, a fraction (b) containing the high-boiling component and the purified glyceryl ether. Furthermore, the purified glyceryl ether is separated from the other divided distillation part.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a phosphoric acid monoester by crystallizing the objective compound in the form of acicular crystal easily separable into solid and liquid. SOLUTION: A phosphoric acid monoester is separated in the form of crystal from a mixture containing the phosphoric acid monoester, a phosphoric acid diester and a solvent by crystallization. The crystallization is carried out by heating the mixture to a temperature (A) above the saturated dissolution temperature (B) and keeping at a supersaturated temperature (C) for >=1 min before cooling the mixture to or below the superdissolution temperature (D).
