权利人:XEROX CORP
摘要:A method of synthesizing polyamide microparticles may comprise: dehydrating and shearing a mixture comprising a matrix fluid, an emulsion stabilizer at about 0.01 wt % to about 50 wt % based on the weight of the matrix fluid, a solvent at about 13 wt % to about 75 wt % based on the weight of the matrix fluid, and a cyclic amide monomer at about 20 wt % to about 90 wt % based on the weight of the matrix fluid to yield an emulsion having a water content of about 1 wt % or less based on the total weight of the emulsion; adding a deprotonating agent to the emulsion at a concentration of about 0.01 wt % to about 1 wt % based on the weight of the matrix fluid; and contacting the emulsion with a polymerization initiator under conditions effective to polymerize the cyclic amide monomer into a plurality of polyamide microparticles.

标 题:Process for preparing a highly concentrated aqueous press cakes of an azo disperse dye from dilute aqueous suspension thereof wherein surfactant is added before the dye is isolated
发明人：WEIDE JOACHIM; DIETZ ERWIN; DEUBEL REINHOLD
权利人:HOECHST AG
摘要: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. n 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.

摘要:Our invention relates to catalysts and their use in the synthesis and conversion of alpha-olefin-containing products, essentially alpha-olefins, primarily from paraffins of renewable origin, having a carbon number of 11-45, and mixtures thereof, which mixtures contain paraffins having a carbon number of 11-45. The main steps of the process are the heterogeneous catalytic dehydrogenation of paraffin with a new zeolite-supported catalyst based on Pt, Pd or Ni, and then the conversion of the resulting olefin-containing product mixture, containing mainly straight-chain internal monoolefins, to lower homologous alpha-olefins—namely, the homogeneous or heterogeneous catalytic ethenolysis by using a ruthenium complex metathesis catalyst (i.e., metathesis using excess ethylene or ethylene metathesis), and/or tandem isomerization and metathesis reactions by using homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with a homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization metathesis, hereinafter referred to as ISOMET), and/or tandem isomerization and ethylene metathesis by using a homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization ethylene metathesis, hereinafter referred to as ethylene ISOMET).

摘要: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.
