Patent number: 4948597Abstract: Described are the schiff base reaction products of alkyl anthranilates having the structure: ##STR1## wherein R" represents ethyl or methyl with ketones and aldehydes defined according to the structure: ##STR2## wherein R' represents methyl or hydrogen and R represents one of the moieties: ##STR3## including compounds defined according to the generic structure: ##STR4## wherein R, R' and R" are defined, supra. Also described are uses of such schiff base reaction products in augmenting or enhancing the aroma or taste of consumable materials including perfume compositions, perfurmed articles (including perfumed polymers, detergents and fabric softeners), colognes, foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos. The schiff base reaction products of our invention also have unexpected, unobvious and advantageous utilities for their deodorancy properties in addition to having valuable properties as fragrance materials and as flavor materials.Type: GrantFiled: May 25, 1989Date of Patent: August 14, 1990Assignee: International Flavors & Fragrances Inc.Inventors: Braja D. Mookherjee, Robert W. Trenkle, Nicholas Calderone, Keith P. Sands
