    摘要: A process for producing rapidly disintegrating pharmaceutical formulations containing an extract is provided. The process comprises providing a dry powdered extract and a lubricant, compacting the powdered extract with the lubricant, using between about 0.5-10% lubricant by weight. The compacting is done using a device that yields flakes. The flakes are then crushed into granules, and the granules are compressed with conventional excipients such as bulking agents, glidants, disintegrants, flow regulators and other additives into pharmaceutical formulations.

    摘要: A pharmaceutical preparation having an active substance of low solubility in water and gastric juices that has an initially liquid carrier system consisting of a hydrophilic component, a hydrophobic component and a solubilizer. The solvent mixture contains 9 to 90 parts by weight of solubilizer and 90 to 5 parts by weight of a hydropholic component, such as polyethylene glykol, 1,2-propylene glykol, 1,3-butanediol, 1,4-butanediol, 1,2-propanediol, glycerol, mannitol, sorbitol or polyoxyethylene polyoxypropylene copolymerisate or mixtures of such substances, and 40 to 1 parts by weight of an oleophilic component, such as natural and/or semisynthetic vegetable or animal oils or synthetic oils, such as neutral oil or waxes. The active substance is dissolved in the carrier system or dispersed in a stable way and for an oral application, is filled into drug capsules made of gelatine. In order to achieve a delayed release of the active substance (delayed-action effect), an adjuvant that is soluble in the carrier system is also added to the carrier system in the amount of up to 10 parts by weight, preferably 2 to 5 parts by weight that, after the dissolving of the capsule wall, develops in contact with the gastric juices a renewing permeable membrane. Suitable adjuvants are ethylcellulose, cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate and vinylacetate crotonic acid copolymers or mixtures thereof.

    摘要: A specific baffle arrangement within a catalytic reactor improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixtrue of hydrocarbon and catalyst. An annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel is arranged on the outside of the riser conduit below the annular outlet and above the stripping zone. Still further, an annular catalyst disengaging wall baffle is arranged on the inside of the shell for again deflecting the mixture, now mostly catalyst, generally downwardly and toward the stripping zone of the vessel. Preferably, the riser baffle and the wall baffle are arrnaged within the shell such that the baffles in concert with the annular discharge outlet form a partial cyclone separating zone between the baffles to thereby improve the separation of hydrocarbon vapors from the catalyst. This cyclone action promotes early disengagement of hydrocarbon vapor from the catalyst and reduces undesirable catalyst carryover in the vapor to conventional cyclones through which the hydrocarbon products are recovered. At the same time, undesirable secondary cracking reactions in the dilute phase are minimized by lowering the concentration of spent catalyst in the dilute phase.

    摘要: The present invention relates to a baffle arrangement that improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixture of hydrocarbon and catalyst. According to the present invention, an annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel is arranged on the outside of the riser conduit below the annular outlet and above the stripping zone. Still further, in the preferred embodiment an annular catalyst disengaging wall baffle is arranged on the inside of the shell for again deflecting the mixture, now mostly catalyst, generally downwardly and toward the stripping zone of the vessel. Preferably, the riser baffle and the wall baffle are arranged within the shell such that the baffles in concert with the annular discharge outlet form a partial cyclone separating zone. This cyclone action promotes early disengagement of hydrocarbon vapor from the catalyst and reduces undesirable catalyst carryover in the vapor to conventional cyclones through which the hydrocarbon products are recovered.
