The compound boron carbide, BC, is an effective catalyst for the alkylation and acylation of aromatics to produce polybenzyls, ketones, esters and alkyl benzenes. The catalyst boron carbide is also effective in conducting intramolecular Friedel-Crafts type reactions to produce cyclic ketones.
Boron Carbide As An Effective Friedel-Crafts Type Catalyst
The compound boron carbide, BC, is an effective catalyst for the synthesis of aromatic esters by reacting benzoyl halides with phenols in the presence of powdered BC.

Abstract:
The toxic effects of platinum compounds used in chemotherapy can be negated by the use of a selenium-containing compound. A new selenium-containing platinum compound has been found to be useful as a so-called platinum compound type anti-cancer medicine which can self-detoxify platinum toxicity.

Prestabilization Of Particulate Matter Prior To Their Dispersion

International Classification:
B32B 900
US Classification:
427304
Abstract:
Disclosed is a method for the plating of a substrate with a composite coating bearing a metallic matrix with finely divided particulate matter dispersed therein. The plating bath is derived by the admixing of a prestabilized particulate matter composition or a precursor thereof along with the required plating chemicals. The use of a prestabilized particulate matter composition offers a convenient way of shipping treated powders devoid of liquids and thereby minimizing shipping costs and aging effects commonly associated with liquid dispersions. The use of the novel prestabilized particulate matter composition along with the plating chemistry provides results substantially the same as those observed from freshly prepared liquid dispersions and their incorporation along with the plating chemicals.
