Abstract: The present invention provides activated carbon with which hydrophilicity is excellent and the amount of steam adsorbed is increased, and provides a method for producing this activated carbon. This activated carbon is characterized in that the amount of basic functional groups in the activated carbon is 0.470 meq/m2 or greater. Preferably the amount of basic groups per specific surface area of activated carbon is 0.200 ?eq/m2 or greater and the ratio of the amount of basic functional groups and the amount of acidic functional groups (basic functional groups/acidic functional groups) is 1.00 or greater. This method for producing activated carbon is characterized in comprising a step for imparting basic functional groups by bringing the activated carbon into contact with a basic substance. According to a preferred embodiment, the method comprises a step for heating the resulting activated carbon in an insert atmosphere.

Abstract: Various 1,4-disubstituted-2,3,5,6-tetrohydroxy-1,4-diphosphorinanes, their oxides and sulfides, methods for the production thereof, and flame-retarded compositions of matter containing them, are disclosed.
Abstract: A minimum hazard visual screening cloud is formed comprised of an aerosol fine spheres of a titanium dioxide composition, in which the particles are of submicron diameter. The cloud is formed by aerosolizing a compact mass of titanium dioxide spheres of submicron diameter through the action of explosively bursting such compact mass in the atmosphere at the desired cloud location.

Abstract: This invention relates to a process for producing tertiarydiamine-boranes by reacting a tertiary diamine with a borohydride in the presence of a carboxylic or mineral acid source. Water is included in the reaction medium in a catalytic amount but insufficient for forming two phases. Excellent selectivity to tertiary diamine-boranes is achieved.
