Abstract:
The present invention provides the method for producing the alkyl glycidyl ether in the bipolar membrane electrodialyzer, including applying current to the composition (A) having a heterogeneous system (oil phase/aqueous phase) containing the chlorohydrin ether at a concentration of not less than 5% by weight, water, and the electrolyte in the electrodialyzer to convert the chlorohydrin ether to the alkyl glycidyl ether through the reaction with OH generated on the bipolar membrane and simultaneously to separate and collect the C1 side product in the form of HC1 (hydrochloric acid).
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an alkylglycidyl ether not requiring a removing operation of by-produced metal salt, capable of remarkably reducing generation of waste water by utilizing water resources effectively, and further capable of producing an alkylglycidyl ether with a high yield.SOLUTION: In the method for producing an alkylglycidyl ether, a composition (A), which is composed of a heterogeneous phase system (oil phase/water phase), has a chlorohydrin ether concentration of 5 mass% or more, and contains water and an electrolyte, is introduced into an electrodialyzer that has a bipolar membrane 24 and 25 and an electric current is applied thereto, so that a chlorohydrin ether contained in the composition (A) is converted into an alkylglycidyl ether by the action of OH- that is generated by the bipolar membrane 24 and 25, while separating and recovering by-produced Cl- in the form of HCl (hydrochloric acid) at the same time.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an epoxy compound which does not require a desalting step separate from the reaction step and does not accompany a loss in yield as well. SOLUTION: The method for producing an epoxy compound comprises bringing a compound represented by formula (I) [wherein R 1 is a 1-24C alkoxy group, a hydroxy group, a halogen or hydrogen; A is an -R 2 O- group (wherein R 2 is a 2-4C alkylene group) or a -CH 2 CH(OH)CH 2 O- group; B is a -CH(OH)CH 2 X group or a -CH(X)CH 2 OH group (wherein X is a halogen); m is a number of 0-10; and n is a number of 0-2] into contact with an anion exchanger to react them, to obtain a reaction product represented by formula (II) (wherein R 1 , A, m, and n are the same as defined above).

Abstract:
PROBLEM TO BE SOLVED: To provide a granulating method which inhibits the volatilization of a perfume component having high volatility to reduce loss as much as possible. SOLUTION: This method for manufacturing perfume particles comprises a step of adding a perfume to a thermoplastic water-soluble binder and granulating the resulting mixture at a temperature of lower than the melting point of the water-soluble binder. Perfume particles are prepared by the manufacturing method. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To reliably remove noble metal-supporting activated carbon contained in a reaction liquid in a short time, in a method for producing a polyoxyalkylene alkyl ether carboxylate.SOLUTION: An oxygen-containing gas is brought into contact with slurry containing a polyoxyalkylene alkyl ether, a noble metal-supporting catalyst whose carrier is activated carbon, and water, whereby the polyoxyalkylene alkyl ether is oxidized to generate a polyoxyalkylene alkyl ether carboxylate. The resulting reaction liquid containing the generated polyoxyalkylene alkyl ether carboxylate is filtered using a filter medium made of a sulfonic polymer to thereby separate the noble metal-supporting catalyst contained in the reaction liquid.
