Abstract: PROBLEM TO BE SOLVED: To provide a further economically advantageous method for producing a phosphoric ester enabling residual organic hydroxy compound to be easily removed without decreasing the yield of the final phosphoric ester. SOLUTION: This method for producing a phosphoric ester comprises reaction of an organic hydroxy compound with a phosphorylation agent; wherein the organic hydroxy compound to be used is such that the content of the component(s) therein whose vapor pressure comes to 0.1 MPa at

Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound having good smell and excellent storage stability and useful as a detergent base by adjusting the pH of an aqueous solution of an N-alkylamidoalkanol sulfuric acid ester salt within a prescribed range. SOLUTION: An aqueous solution of an N-alkylamidoalkanol sulfuric acid ester salt of formula II (M is a cation) having a pH of 5-8 is produced by sulfating an N-alkylamidoalkanol of formula I (R is a 6-22C straight or branched- chain alkyl, alkenyl, hydroxyalkyl, etc.; R is H, a 1-22C straight or branched- chain alkyl, alkenyl, etc.; R is a 1-5C straight or branched-chain alkylene; R is a 2-3C straight or branched-chain alkylene; (n) is an average addition molar number of alkylene oxide and is 0-50) with a sulfating agent and neutralizing the produced N-alkylamidoalkanol sulfuric acid ester with a basic substance in the state of an aqueous solution.

Abstract: PURPOSE:To obtain the subject compound in an industrially advantageous way, useful as a detergent, emulsifier, or a raw material for medicines, etc., by purifying a mixture containing a phosphoric ester (salt) and orthophosphoric acid (salt) through removing the latter by using a reverse osmosis membrane. CONSTITUTION:A mixture containing a phosphoric ester (salt) of e.g. the formula (R is an 8-36C alkyl or alkenyl; R is H, an 8-36C alkyl or alkenyl; M is H, an alkali metal, alkanolamine or ammonium) and orthophosphoric acid (salt) is treated by using a reverse osmosis membrane device equipped with a reverse osmosis membrane consisting of an electrically chargeable synthetic polymer and having a sodium chloride exclusion rate of 0-90% to effect purification through removing the orthophosphoric acid (salt) from the mixture, thus obtaining the objective phosphoric ester (salt) in an industrially advantageous way, widely useful as detergents, textile processing agents, emulsifiers, rustproofing agents, liquid ion exchangers or medicines.

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 acid ester having >=3 ester exchange degree) are mixed with fats and oils under heating and the prepared heated mixture is cooled to crystallize a sucrose fatty acid ester having high [SME] content. The crystallized substance is subjected to solid-liquid separation to give a crystallized sucrose fatty acid ester having high [SME] content and a sucrose fatty acid esters having high [SDE] and [SPE] contents.
