    摘要: In treating a cellulose fiber article with 1,2,3,4-butanetetracarboxylic acid to improve properties, 1,2,3,4-butanetetracarboxylic acid containing up to 200 ppm of nitro radical is used, whereby the cellulose fiber article can be prevented from coloring to the utmost extent. The intended results of the invention can be achieved to a remarkable extent when using 1,2,3,4-butanetetracarboxylic acid containing up to 200 ppm of nitro radical and prepared by oxidizing tetrahydrophthalc acid and/or tetrahydrophthalic anhydride with hydrogen peroxide.
