  • Publication number: 20140275611
    Abstract: A means of directing nucleation and crystal growth has been developed in which these stages of crystallization are influenced by surface energy modifications to amorphous substrates. The surface energy of a substrate can affect the contact angle, line tension, wettability and energetics of the interaction with a supersaturated solution, and these factors are important in crystallization. The use of amorphous substrates creates an opportunity to modify their surface to create useful ranges of surface energies that enhance or inhibit, as may be advantageous, the thermodynamic, kinetic, or a combination of both, factors in nucleation, crystal growth, or crystallization from a supersaturated solution.

  • Publication number: 20030216593
    Abstract: The present invention provides a fast, high yield method for preparing salicylamide intermediates. The method comprises reacting a C4 or higher alkyl ester of salicylic acid or derivative thereof with at least one amine selected from the group consisting of monoalkylamines, dialkylamines, ammonia, and any combination of any of the foregoing in alcohol to yield the sali-cylamide. The C4 or higher alkyl ester of salicylic acid or a derivative thereof is preferably prepared by reacting salicylic acid or a derivative thereof with a C4 or higher alcohol in presence of at least one of sulfuric acid, a sulfonic acid, and a mineral acid. This process for preparing salicylamide intermediates from salicylic acid or derivative thereof generally has a cycle time of about 2 days, and yields about 95% of a 99% pure material. In comparison, when a C3 or lower alkyl ester is used in lieu of the C4 or higher alkyl ester, the process generally has a cycle time of 7-9 days and yields about 60% of a 95% pure material.

    Abstract: The invention relates to a process for purifying and decolorizing a phenyl ester salt. The process combines a phenyl ester salt with a solvent to form a mixture and then stirs the mixture to form a slurry. The phenyl ester salt is substantially insoluble in this solvent. The process then collects the phenyl ester salt from the slurry. The collected phenyl ester salt may then be optionally dried or recrystallized. The collected phenyl ester salt is dissolved in a solvent to form a solution. The solution is decolorized and then spray dried to form a powder of the phenyl ester salt. As a result of the process the phenyl ester salt powder has a higher purity and an improved color as compared to the starting phenyl ester salt.

    Abstract: Compositions degrading by hydrolysis to release a bioactive compound having carboxylic acid moieties, which are organic acid anhydrides having the following formula: ##STR1## wherein R' is a residue of a therapeutic bioactive compound, for example, a non-steroidal anti-inflammatory agent; a penicillin or cephalosporin antibiotic; or bioactive compounds for non-therapeutic use, for example, herbicides, insecticides, fungicides, antimicrobials, pesticides, pheromones, and fertilizers; m is an integer of between 1 and 3; and R is a carrier. The resulting mixed anhydrides are characterized by having between one and three drug molecules attached to a single carrier molecule. The prodrugs are highly susceptibility to hydrolytic degradation in a predictable and controlled fashion, have variable solubilities in water and lipids, with increased biomembrane transport, elicit a bio-affecting/pharmacological response, and are less irritating to topical and gastric or intestinal mucosal membranes.

  • Patent number: 5041615
    Abstract: Bis(salicyl) diesters useful as cross-linking agents for hemoglobin are prepared in high yield and purity by reacting salicylic acid or a derivative thereof with a lower aliphatic dicarboxylic acid halide in a lower aliphatic ketone or nitrile solvent in the presence of a pyridine derivative. The desired diester is recovered from the resulting insoluble pyridine derivative salt.

  • Patent number: 4692546
    Abstract: Acyloxy aromatic carboxylic acids, e.g., 4-acetoxybenzoic acid, are prepared by oxidizing with oxygen an acyloxy aromatic ketone, e.g., 4-acetoxyacetophenone in the presence of manganese cations and a lower-carboxylic acid anhydride as catalyst and a co-reductant or promoter. The acyloxy aromatic ketone may be prepared by acylating a hydroxy aromatic ketone, e.g., 4-hydroxyacetophenone, which has the effect of "masking" the hydroxyl group of the ketone in a manner necessary to effect the subsequent transition-metal catalyzed oxidation of the ketone to the acyloxy aromatic carboxylic acid.
