Abstract

Abstract An adsorbing diacidifier for oily substances in a powder form, wherein the adsorbing diacidifier comprising dehydrated natural or synthetic zeolites and an aqueous solution of sodium hydroxide or potassium hydroxide adsorbed into said natural and synthetic zeolite for fixation, and in the adsorbing deacidifier, the ratio of water is from 10 to 40 weight percent. The adsorbing diacidifier is capable of effecting diacidification of oily substances through simple procedure by adding the diacidifier to an oily substances, with subsequent filtering after stirring for mixing. Another adsorbing diacidifier for oily substances, wherein adsorbing diacidifier comprising natural or synthetic zeolites and an aqueous solution of sodium hydroxide or potassium hydroxide adsorbed into said natural or synthetic zeolites for fixation and in the material thus prepared, the ratio of water is from 10 to 40 weight percent, and adding distomaceous earth at any desired ratio.
