PURPOSE:To efficiently prepare a powdery deodorant much in the support amount of metal phthalocyanine polycarboxylic acid and having high deodorizing effect, by dispersing metal phthalocyanine polycarboxylic acid and an adsorbent in an org. solvent to support metal phthalocyanine polycarboxylic acid by the adsorbent and evaporating the solvent. CONSTITUTION:As the center metal M of metal phthalocyanine polycarboxylic acid represented by formula I (wherein M is a metal and X is a carboxyl group or a non-substituted hydroxyl group), Fe, Co, Mn, Ti, V, Ni, Cu, Zn, Mo, W and Os can be used but Fe, Co or a mixture of Fe and Co is pref. As an adsorb ent, for example, activated carbon, a silica gel, silica, zeolite, bentonite or alumina are used in a powdery form. The particle size of the powder is 0.01mum-5mm, pref., 0.1-100mum. The addition amount of the adsorbent is 1-1,000pts., pref., 2-100pts. by wt. of 1pts. of metal phthalocyanine polycarboxylic acid. As an org. solvent, methyl ethyl ketone and ethyl acetate are pref. A dispersing apparatus such as a ball mill is used in dispersing treat ment. After treatment for a predetermined time is finished, the solid components are filtered and dried. |
