Abstract
The present invention provides a deodorizer consisting of the water-soluble metallophthalocyanine represented by the formula: ##STR1## wherein, "Met" is a central metal, X is an acidic group or alkali metal salt thereof, m and p are respectively an integer of from 1 to 15, and m+p is not more than 16. The deodorizer shows excellent deodorizing ability for an aldehyde-origin odor.
Claims15
A water-soluble metallophthalocyanine represented by the formula:
- ##STR11## wherein, "Met" is a central metal, X is an acidic group or alkali metal salt thereof, m and p are respectively an integer of from 1 to 15, and m+p is not more than 16.
A material for deodorizing at least one odor selected from the group consisting of an aldehyde-selected from the group consisting of an aldehyde-origin odor, an amine-origin odor, and a sulfur origin odor, consisting of 10 to 90% by weight of a metallophthalocyanine which has 1 to 16 amino groups as a substituent, and a metallophthalocyanine which has 1 to 16 acidic groups or alkali metal salt thereof as a substituent.
A process for preparing a metallophthalocyanine compound, wherein polyethylene glycol dialkyl ether is used as a reaction solvent.
A process for preparing a metallophthalocyahine compound which comprises the step of:
- heating a phthalic acid derivative, urea, and metal halide, in polyethylene glycol dialkyl ether, in the presence of a condensation catalyst.
