    摘要: The reaction mixture obtained in the enzymatic reaction of fumaric acid to form L-malic acid contains the L-malic acid and unreacted fumaric acid as their salts. To recover pure solutions of L-malic acid the reaction mixture is treated at 50.degree. to 150.degree. C. with cation exchangers. The eluate after concentration to 30 to 80 weight % content of L-malic acid is filtered. The pure L-malic acid is recovered by evaporating the solutions, in a given case after treatment with activated carbon.

    摘要: A penetrating concentrate containing a biocidal amount of a biocide uses a penetrating carrier vehicle containing an emulsifiable copolymer of a cyclic diene and a polymerizable, unsaturated glyceride. For biocides, such as iodopropargyl carbamate, which otherwise requires use of significant amounts of co-solvent to disperse, is directly soluble in the copolymer thereby eliminating or at least substantially reducing the need for co-solvents to assure stability of the biocide in the formulation. The concentrate also exhibits a low level of volatile organics.

    摘要: The present invention is generally directed to compositions and formulations that can be used for the treatment of diseases such as End Stage Renal Disease (“ESRD”) and Chronic Renal Insufficiency (“CRI”). Specifically, it is directed to lanthanum-based compounds that bind phosphate and that can be formulated to provide for a reduced pill burden relative to other phosphate binders. In a formulation aspect of the present invention, a formulation is provided the includes a lanthanum-based, phosphate binder. The formulation is typically characterized in that in may be swallowed without chewing. Formulations of the present invention, along with a lanthanum-based compound, may optionally include the following: mass diluting agents; binders; coatings; compression/encapsulation aids; disintegrants; lubricants; plasticizers; slip/anti-electrostatic agents; powder lubricants; and, sweeteners. Where the formulation is in the form of a tablet, it typically has a volume between 0.3 cm3 and 1.2 cm3, preferably between 0.35 cm3 and 0.50 cm3. Each tablet typically includes enough phosphate binder such that only 3 or less tablets need to be ingested each day for a patient suffering from ESRD.
