<P>PROBLEM TO BE SOLVED: To provide a reducing agent for reducing volatile organic compounds, NOX, and SOX in a room. <P>SOLUTION: In the reducing agent, a titanium phosphate compound expressed by Ti(OH)<SB>x</SB>(PO<SB>4</SB>)<SB>y</SB>(HPO<SB>4</SB>)<SB>z</SB>(H<SB>2</SB>PO<SB>4</SB>)<SB>l</SB>(OR)<SB>m</SB>(R is a 1-4C alkyl group; x is an integer of 0-4; y is 0 or 1; z is an integer of 0-2; l is an integer of 0-4; m is an integer of 0-4; and x+3y+2z+l+m=4) is incorporated as an effective component, or sodium silicate is incorporated into the titanium phosphate compound. The titanium phosphate compound is obtained by a process in which after titanium tetrachloride is reacted with water, a 1-4C alcohol, or a mixed solution of water and the alcohol, the product is reacted with phosphoric acid. <P>COPYRIGHT: (C)2004,JPO |
