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:
Un procedimiento para producir un éter de glicerilo que comprende introducir un compuesto representado por la fórmula general (I): **Fórmula** en la que R es un grupo de hidrocarburo que tiene de 1 a 20 átomos de carbono, todos o una parte de sus átomos de hidrógeno pueden estar sustituidos por un átomo de flúor; OA, que puede ser idéntico o diferente, es un grupo oxialquileno que tiene de 2 a 4 átomos de carbono; y p es 10 el número de 0 a 20, y agua a un reactor; y someter el compuesto a una reacción hidrolítica en condiciones en las que el agua está en estado subcrítico o en estado supercrítico, y en la que el procedimiento incluye la etapa de: (1) recoger agua de una mezcla de reacción después de la reacción hidrolítica, ajustando un pH del agua a un pH que varía de 3,5 a 12 e introduciendo el agua recogida en el reactor; o (2) someter el agua recogida de una mezcla de reacción tras la reacción hidrolítica a un tratamiento de filtración con una membrana de ósmosis inversa hidrofílicamente tratada, e introducir el agua tratada resultante como agua reciclada en el reactor.
Abstract:
A process for producing a glyceryl ether which comprises supplying a compound represented by the general formula (I): (I) (wherein R represents a C1-20 hydrogen group in which part or all of the hydrogen atoms may have been replaced with a fluorine atom; OA's may be the same or different and each represents C2-4 oxyalkylene; and p is a number of 0-20) and water to a reactor and hydrolyzing the compound under such conditions that the water is in a subcritical or supercritical state. The process for glyceryl ether production includes: a step (1) in which the water is recovered from the reaction mixture resulting from the hydrolysis, regulated so as to have a pH of 3.5 or higher, and then supplied to the reactor; or a step (2) in which the water recovered from the reaction mixture resulting from the hydrolysis is filtered through a reverse osmosis membrane and the treated water obtained is supplied as recycle water to the reactor.

PROBLEM TO BE SOLVED: To suppress generation of soot upon producing a water gas from a polyhydric alcohol and water. SOLUTION: The method for producing a water gas includes allowing a reactant fluid that contains a polyhydric alcohol and water to flow through a reaction site 14a, which is provided with a catalyst 18 having a surface extending in the flowing direction of the reactant fluid, at an average flow rate of not less than 0.05 m/s with a reaction time of not less than 1.0 s.

Abstract:
PROBLEM TO BE SOLVED: To provide an efficient method for producing a high-quality glyceryl ether using recycled water. SOLUTION: The method for producing the high-quality glyceryl ether comprises feeding a reactor with water and a glycidyl ether of the general formula(I)(wherein, R is a 1-20C hydrocarbon group with part or the total hydrogen atoms therein optionally substituted with fluorine atom(s); OA are same or different and each is a 2-4C oxyalkylene group; and p is 0-20) to hydrolyze the glycidyl ether under such conditions that the water is in a subcritical or supercritical state. This method involves the step of subjecting the water retrieved from the reaction mixture after hydrolysis reaction to filtration treatment with a reverse osmosis membrane and feeding the thus treated water into the reactor as recycled water.
