Roderick J. Chuck has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for the preparation of nicotinic acid
    Patent number: 6376677
    Abstract: Nicotinic acid is produced from aqueous solutions of ammonium nicotinate by spray-drying. The nicotinic acid can be freed from residual ammonium nicotinate by a thermal post-treatment in a fluidized bed or under reduced pressure. The process is suitable in particular for the work-up of the reaction mixture produced in the oxidation of 3-methylpyridine with atmospheric oxygen, with the ammonia and, if appropriate, the water, being able to be recycled. Nicotinic acid (“vitamin PP”) is an important additive to foodstuffs and feedstuffs.
    Type: Grant
    Filed: June 20, 2000
    Date of Patent: April 23, 2002
    Assignee: Lonza AG

  • Process for preparing nicotinamide
    Patent number: 5719045
    Abstract: A process for preparing nicotinamide, wherein, in the first stage, 2-methyl-1,5-diaminopentane is catalytically converted into 3-picoline, then the 3-picoline is converted via an ammonoxidation into 3-cyanopyridine and, finally, the 3-cyanopyridine is converted microbiologically into the nicotinamide.
