    摘要: Uncoated technical fabric is produced in a dense weave with low air permeability. The fabric contains polyamide filament yarns with a hot air shrinkage of 6 to 15% (determined at 160.degree. C.) and has an at least substantially symmetrical fabric construction. The fabric is adjusted to the required air permeability by a treatment in an aqueous bath at 60.degree. to 140.degree. C.

    摘要: A method for site-specific in-vivo activation of a prodrug in an animal using an activator-targeting moiety conjugate to localize an activator at a predetermined site of use and a prodrug compound that is converted to an active drug in the presence of the activator. In the preferred embodiment, the targeting moiety, the activator, and the prodrug demonstrate little or no immunogenicity in the animal being treated. The targeting moiety is relatively specific for binding to the target tissue than to non-target tissue. The activator is not found or present in only small amounts in circulation or in non-target tissue, does not have a substrate for its activity in circulation or in non-target tissue, can be linked to the targeting moiety, and is capable of converting the prodrug to an active drug. The prodrug is selected for its ability to exert a cytotoxic activity on the target tissue after conversion by the activator.

    摘要: The method for manufacturing dibenzylamine by reacting benzaldehyde and ammonia in the presence of hydrogen and a hydrogenation catalyst in an inert organic solvent is characterized by the fact that the reaction is conducted with an ammonia ratio of >0.5 mol per mol benzaldehyde and with a hydrogenation catalyst containing a platinum metal and/or a ferrous metal on a carrier. The method is performed at low temperatures, preferably 40.degree.-90.degree. C. In particular, a high selectivity for dibenzylamine of more than 90% is achieved with practically complete benzaldehyde conversion.

    摘要: A dialysis membrane in the form of a hollow fiber with a continuous internal cavity is made of cellulose acetate or a cellulose acetate derivative. The hollow fiber is made by using a gas to form the internal hollow cavity. A dialysis membrane in the form of a hollow fiber with a continuous hollow cavity may be made in a process using a spinning solution containing an organic carboxylic acid. Modification agents can be added to the solution and the solution extruded through a spinneret suitable for manufacturing hollow fibers, while an internal medium is introduced simultaneously into the internal cavity of the forming hollow fiber. The precipitation of the dialysis membrane thus formed and an ordinary further aftertreatment take place subsequently in a precipitation bath. The hollow fiber is made by using a gas as the internal medium to form the internal cavity.

    摘要: In a process for the preparation of 2-mercaptobenzothiazole from aniline, sulfur and carbon disulfide under pressure and for separation of the 2-mercaptobenzothiazole from the crude reaction product by cooling and recycling the desirable intermediates and by-products into the reactor together with aniline, sulfur and carbon disulfide, the reaction is carried out using a residence time in the reactor of at least one hour to a time before the 2-mercaptobenzothiazole product thus-formed begins to decompose into undesirable intermediate products. A maximum hydrogen sulfide pressure is maintained on quenching to a temperature ranging between 220 and 280.degree. C. by mixing the crude reaction product with carbon disulfide at a temperature sufficient to obtain a homogeneous quenched mixture. The hydrogen sulfide is removed completely only after crystallization of the 2-mercaptobenzothiazole.
