Patent number: 4828622Abstract: According to the invention, addition of one or more surfactants having a cloud point in aqueous solution to an aqueous suspension of a solid gives after the isolation of the solid at a temperature above the cloud point aqueous press cakes containing a large amount of this solid. The direct processing of press cakes as obtained for example after the synthesis and isolation of dyes or pigments to give practical aqueous pastes or dispersions requires a minimum solids content in the press cakes. The minimum content is frequently not obtained when conventional methods of isolation are used, so that it is necessary to proceed via the indirect route of drying to obtain the powders and redispersing the powders. By using the process according to the invention it is possible to cut out the costly indirect route or, if desired, to reduce the expense of drying to obtain powders by an appreciable margin.Type: GrantFiled: May 5, 1988Date of Patent: May 9, 1989Assignee: Hoechst AktiengesellschaftInventors: Joachim Weide, Erwin Dietz, Reinhold Deubel

Patent number: 4785082Abstract: According to the invention, addition of one or more surfactants having a cloud point in aqueous solution to an aqueous suspension of an azo disperse dye gives after the isolation of the dye at a temperature above the cloud point aqueous press cakes containing a large amount of this dye.The direct processing of press cakes as obtained for example after the synthesis and isolation of azo disperse dyes to practical dispersions for use requires a minimum dye content in the press cakes. The minimum content is frequently not obtained when conventional methods of isolation are used, so that it is necessary to proceed via the indirect route of drying to obtain powders and redispersing the powders. By using the process according to the invention it is possible to cut out the costly indirect route or, if desired, to reduce the expense of drying to obtain powders by an appreciable margin.Type: GrantFiled: November 5, 1985Date of Patent: November 15, 1988Assignee: Hoechst AktiengesellschaftInventors: Joachim Weide, Erwin Dietz, Reinhold Deubel
