Abstract

PURPOSE:To economically provide required chemicals by using a 2-phenoxy anthraquinone polysulfonic acid or its salts as the major component of oxidation-reduction chemical for wet desulfurization process. CONSTITUTION:Oxidaton-reduction chemicals used in wet desulfurization process, especially for a thread forming process, consist of 2-phenoxy anthraquinone polyflufonic acid of formula I (where M is H, Na, K, or NH4; n is 1 or 2) or its salts, and as required contain 2,7-anthraquinone disulfonic acid. The 2-phenoxy anthraquinone polysulfonic acid of formula I or its salts are preferably 2-phenoxy anthraquinone trisulfonic acid of formula II or its salts, or 2-phenoxy anthraquinone tetrasulfonic acid of formula III or its salts, or a mixture of both.
