A harmful substance remover, which is used to remove any of ethylene, mercaptans, amines and aldehydes, is a solid product having a specific surface area of 100 m.sup.2 /g or more obtained by hydrolyzing a metal alkoxide in the presence or absence of a noble metal. The harmful substance remover is utilized by contacting a harmful substance therewith. Such contacting may take place under irradiation of ultraviolet rays.

Method for removing a harmful substance selected from the group

A hydraulic composition comprises a hydraulic component and an organic hydrogel, and optionally aggregate, a reinforcing material and other additives and has a slump value, determined by the testing method of JIS A1101, of not more than about 1 cm in a concrete formulation and a flow value, determined by the testing method of JIS R5201, of not more than about 120 mm in a mortar or paste formulation.

Hydraulic composition

A deodorant carrying urethane foam contains a chemically-reactive deodorant distributed uniformly therein wherein weight loss of said deodorant is not more than 15% when kept at atmospheric pressure and 150.degree. C. for 1 hr. The process of preparing the above-mentioned deodorant carrying urethane foam comprises adding a chemically-reactive deodorant to a urethane foam composition with mixing to permit said deodorant to be uniformly distributed therein, and then causing the resultant mixture to react and produce a foam.

Deodorant carrying urethane foam and process of preparing the same

A deodorizing urethane foam comprising a urethane foam substrate and a deodorizing component. The deodorizing component is composed of (A) a Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or a derivative of the reaction product and optionally (B) a copper compound. This urethane foam is produced by foaming a mixture of materials for the urethane foam substrate and the Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or its derivative of the reaction product and optionally the copper compound.
