Formulations/Preparations:
•lemon and bergamot essential oils were blended into an imitation pear flavor consisting of more than 90% by weight of amyl acetate; vanillin, rose absolute, and sometimes a trace of raspberry aroma were also added to better balance the resulting formulation. a few esters--geranyl propionate, amyl valerate, ethyl acetate, and ethyl butyrate--were added to amyl acetate formulations for special flavoring effects. some formulations also call for the use of aldehyde c14 (gamma-undecalactone). commercial grade •grades: reagent; technical •grades: commercial (85-88%). high test (85-88%), technical (90-95%), pure (95-99%); special antibiotic grade. amyl acetate is also sold by original source, as from fusel oil, pentane, or oxo process. commercial grade
