  • Circular economic methods for fragrance ingredients
    Patent number: 11873277
    Abstract: Disclosed is a method for converting cymene generated from renewable low value terpene streams into renewable benzene, toluene, xylenes, and cymene isomers (ortho and meta) under flow disproportionation reaction conditions, which compounds are basic building blocks for fragrance materials. This technology has potential to replace high volume petrochemical-based feedstocks with plant-based building blocks that can fill the renewability gap for key fragrance ingredients.
    Type: Grant
