Phenethyl acetate and n-alkanes (C8-C20) were purchased from Sigma-Aldrich (St Louis, MO, USA).
Immediately, 10 [micro]L of phenethyl acetate solution (5 [micro]g/mL in methanol) as an internal standard was added to each sample before the trap.
([dagger]) Values expressed as phenethyl acetate equivalent (5 [micro]g/mL) and given means (n = 2); n.d., not detected.
Among the compounds of higher sensory relevance, we found ethyl octanoate, ethyl hexanoate, phenethyl acetate
, [beta]-(E)-damascenone, (E)-ethylcinnamate, 2-methylbutyl acetate, 3-methyl-1-butanol, ethyl 3-(E)-hexenoate, and methyl 5-hexenoate.
Yadav and Mehta (1994) reported that Amberlyst 15 was highly active compared to other solid acids in producing phenethyl acetate and cyclohexyl acetate.
Yadav and Mehta (1994) calculated the effectiveness factor of the Filtrol-24 catalyst for producing phenethyl acetate and of the Amberlyst catalyst for cyclohexyl acetate production.
