Properti Kimia

Wiski Lactone ditemokake minangka cis- lan trans-isomer ing wiski lan volatil oakwood; thecis-isomer luwih penting ing istilah indrawi. Cairan kasebut meh lan ora ana warna kanthi ambune kaya koumarin, anget, manis, lan kaya koumarin.
Campuran trans cis bisa disiapake kanthi reaksi radikal pentanal kanthi asam crotonic banjur diikuti karo siklisasi reduktif ?? - oksoidid kanthi natrium boron hidrida / asam sulfat. Iki digunakake ing aromacompositions, contone, kanggo omben-omben.
