Title: Innovations by Sanjay I Amin
Introduction
Sanjay I Amin is a notable inventor based in Oshtemo Township, MI (US). He has made significant contributions to the field of chemistry, particularly in the development of processes related to arylalkanoic acids, including ibuprofen and naproxen. With a total of 3 patents to his name, his work has had a considerable impact on pharmaceutical manufacturing.
Latest Patents
One of his latest patents focuses on an improved process for preparing arylalkanoic acids. This process involves the conversion of a selected alpha-haloketal derivative of a 1-haloethyl aryl ketone to the haloalkyl ester of the arylalkanoic acid using a zinc salt catalyst. The improvement includes reacting a ring-substituted 6-membered ring ketal with a soluble zinc carboxylate salt to form the corresponding 3-haloalkyl arylalkanoic acid ester. The ester is then converted to the alkali metal salt of the acid with base in an aqueous/water-insoluble organic liquid mixture. The crude salt is subsequently converted to the corresponding acid in an aqueous/water-insoluble solvent mixture. The organic solution of the acid is washed with a pH 7.0 to 8.0 buffer solution, and the arylalkanoic acid product is separated from the mother liquor, which is recycled to recover the arylalkanoic acid values. Another significant patent involves the crystallization of ibuprofen from a delta H greater than 8 liquid, such as methanol, to obtain ibuprofen crystals with improved properties.
