METHOD AND APPARATUS FOR SOLUBILIZING ORGANIC SOLID

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for solubilizing an organic solid, by which the organic solid can efficiently be solubilized at a low cost and a treating liquid can be restrained from discoloration. SOLUTION: This method for solubilizing the organic solid comprises a step to keep a water medium 1 containing the organic solid at 120-350°C under the pressure that the medium 1 is kept in a liquid phase in an airtight vessel 11 and a step to irradiate the medium 1 with an ultrasonic wave under such a condition. The solubilization can be performed by adding an acid or an alkali to the medium 1 containing the organic solid. COPYRIGHT: (C)2003,JPO
