Hazard Information

Description

2-Octanone has a floral and bitter, green, fruity (unripe apple) odor with a bitter camphoraceous taste. May be synthesized by the oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid; also by oxidation of 2-octanol over zinc oxide at 330 - 340°C.

Chemical Properties
