摘要： A method of manufacturing a granular detergent by spray drying a slurry of cleaning materials, which comprises: wetting the surfaces of the granules of detergent formed by spray drying; coating the thus wetted surfaces with 0.02 - 4 parts by weight of powdery builders per 1 part by weight of the granules of detergent; and drying it thereafter.

摘要： A process for improving the properties of granular detergents, that is, caking preventability, fluidity and particle hardness, which comprises spray-coating a coating agent [I] consisting of the silicates, sulfates, carbonates and hydroxides of alkali metals and a coating agent [II] consisting of polyvalent metal sulfates separately onto a granular detergent obtained by the conventional spray granulating method, tumbling granulating method, piston granulating method, pressure granulating method and the like, under a condition in which the granular detergent is in a fluid state; causing a reaction on the surface of the granular detergent particles; and forming thereon a coating film of a water-insoluble or poorly water-soluble substance.

摘要： A process for recovering alkyl sulfonic acid from a photosulfoxidation reaction mixture of an alkane comprising the steps of: separating a major portion of the unreacted alkane contained in said reaction mixture by settling; subjecting thus treated reaction mixture to steam-distillation to remove the remaining portion of the unreacted alkane together with the sulfur dioxide therefrom; subsequently separating the sulfuric acid without heating from the resulting mixture by settling, thereby recovering the alkyl sulfonic acids.
