Document Type and Number:
WIPO Patent Application WO/2013/190794
Kind Code:
A1
Abstract:
A method for preparing a concentrated aqueous solution of an organic compound, said method comprising: adjusting an aqueous solution, which contains an organic compound having two or more hydrophilic groups per molecule at a concentration less than 40 mass%, to a concentration of the aforesaid organic compound of 40 mass% or greater; and then dehydrating and concentrating the aqueous solution, which has been adjusted to a concentration of the aforesaid organic compound of 40 mass% or greater, by irradiating the same with ultrasonic waves and thus atomizing water therein.
