    Abstract: In the process for preparing formamide by reaction of ammonia and carbon monoxide in the presence of at least one catalyst, sodium diformylamide is used as catalyst. If sodium methoxide is used as further active component, sodium diformylamide can be formed from this. In this process, sodium diformylamide is a particularly active and stable catalyst which can be recycled.

  • Patent number: 6417399
    Abstract: The present invention generally relates to the individual stereoisomers of the drug valnoctamide (a mixture of four stereoisomer kinds, VCD-valmethamide or 2-ethyl-3-methyl pentanamide) useful in treatment of neurological and psychotic disorders such as different kinds of epilepsy and affective disorders, and useful as tranquilizers and to treat pain, and to pharmaceutical compositions containing, as an active ingredient, these stereoisomers. The present invention further relates to a method for stereoselective separation and quantification of the four stereoisomers from a racemic mixture of VCD or plasma of patients treated with the racemic drug. The present invention further relates to a unique method for the synthesis of the individual stereoisomers.

  • Patent number: 6399825
    Abstract: A process for the increasing the conversion of raw materials into DMAc by increasing the temperature at which the reaction occurs. The higher temperature is achieved by installing a pressure control valve in the dimethyl amine recycle line returning to the scrubber column. This raises back pressure on reactor and reactor column. The higher pressure raises the temperature in reactor vessel. Higher temperature increases the reaction rate and efficiency. The implementation of this invention greatly increases the capacity of existing equipment without adding large amounts of capital to expand conventional methods.
