Title:
PRODUCTION OF ORGANIC COMPOUND SHOWING AFFINITY TO HYDROPHILIC MEDIUM
Document Type and Number:
Japanese Patent JP3864432
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily obtain an organic compound in high efficiency by effectively utilizing resources such as brown coal which is inexpensive and exists in plenty as a raw material by oxidizing a solid high molecular weight organic compound with oxidizing agent in the presence of a hydrophilic solvent.
SOLUTION: (A) A solid high molecular weight organic compound (example: low-grade coal such as brown coal or peat) is oxidized (in a condition such as 40-80°C) by adding (C) an oxidizing agent (preferably one or more compounds selected from the group consisting of hydrogen peroxide, ozone, dichromic acid, permanganic acid, nitric acid) in the presence of (B) a hydrophilic solvent (preferably water or alcohol). The component A is preferred to be previously swollen with lower alcohol (example methanol, etc.) and, for example, formic acid, acetic acid and malonic acid are preferably obtained as objective organic acids.
