Document Type and Number:
Japanese Patent JPS5626714
Kind Code:
A
Abstract:
PURPOSE: To manufacture the titled composition having superior storage stability by blending mountain cork and at least one of oxalic acid, maleic acid and EDTA in a specified ratio and reacting the blend in a solvent.
CONSTITUTION: 100g Mountain cork such as sepiolite, attapulgite or mountain wood is blended with at least one of oxalic acid, maleic acid and EDTA so that the amount of the acid becomes ≤ about 1.85 equivalent.
