  • Patent number: 8048655
    Abstract: A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. A tertiary amine and CO2 are introduced to the solution to form the insoluble carbonate salt and a complex between the acid and an amine. A water immiscible solvent, such as an alcohol, is added to extract the acid/amine complex from the dilute salt solution to a reaction phase. The reaction phase is continuously dried and a product between the acid and the solvent, such as an ester, is formed.

  • Patent number: 8048919
    Abstract: This invention is based upon the unexpected discovery that ethyl lactate can be used as an emulsifying/dispersing excipient for numerous biologically active compounds without destroying the pharmacological activity of the active ingredient. Ethyl lactate proves to be an extremely effective agent for solubilizing biologically active compounds that are difficult to solubilize in conventional excipients. The operability of this invention is predicated on the necessity for the ethyl lactate to be essentially free of peroxide compounds. Such pharmaceutical grade ethyl lactate can be made by reducing the level of peroxide compounds in high purity ethyl lactate by hydrogenation, reduction with a non-catalytic chemical reducing agent, absorption into activated carbon or alumina, or distillation.

  • Patent number: 8039650
    Abstract: A diamine and an epihalohydrin are subjected to ring-opening addition reaction in the presence of water, to thereby produce a tetrahalohydrinamino compound (i.e., halohydrin compound). Thereafter, the halohydrin compound is reacted with an alkali metal hydroxide in the co-presence of a phase-transfer catalyst, to thereby allow cyclization reaction to proceed. An alkali metal halide by-produced during the cyclization reaction is dissolved in water and removed through phase separation. The resultant organic layer is washed with water for phase separation. Then, a crude tetraglycidylamino compound obtained by recovering unreacted epihalohydrin through evaporation is dissolved in an organic solvent and washed with water for phase separation. Subsequently, the organic solvent is recovered through evaporation under reduced pressure with heating, to thereby isolate a tetraglycidylamino compound (i.e., a product of interest).

  • Patent number: 8039548
    Abstract: A process for purification of a hydroxycarboxylic acid by distillation, comprising: distilling a hydroxycarboxylic acid solution containing a high-boiling point hydroxy compound comprising at least one species selected from the group consisting of alcohols and phenols having a higher boiling point than the hydroxycarboxylic acid.
