  • Green catalytic process for the synthesis of acetyl salicylic acid
    Patent number: 7544831
    Abstract: The present invention provides a green catalytic process for the synthesis of acetyl salicylic acid using solid acid catalysts at atmospheric pressure. The invention involve the solid acid catalyst such as sulfated transition metal oxides namely nano-crystalline sulfated zirconia, sulfated titania; modified zeolites namely zeolite H-beta, H-Y, H-ZSM-5 and K-10 montmorillonite clay in a solvent free environment using salicylic acid and acetic anhydride with yield about 95% and high selectivity (100%). The solid acid catalysts can be recovered, regenerated and reused.
    Type: Grant
    Filed: September 21, 2007
    Date of Patent: June 9, 2009
    Assignee: Council of Scientific and Industrial Research
    Inventors: Raksh Vir Jasra, Beena Tyagi, Manish Kumar Mishra

  • Catalytic process for the preparation of isolongifolene
    Patent number: 7132582
    Abstract: The present invention relates to a catalytic process for preparation of isolongifolene using nanocrystalline solid super acid. This process is an eco-friendly, single step, solvent free catalytic process for the preparation of a tricyclic sesqui-terpene hydrocarbon, isolongifolene. More particularly, the present invention provides a process for the catalytic isomerisation of longifolene to iso-longifolene using nano-crystalline sulfated zirconia as a solid super acid catalyst.
