DL-Isoborneol Structural

What is DL-Isoborneol?

Description

Isoborneol has a piney, camphoraceous odor. May be prepared by the hydrolysis of isobomyl acetate, or by catalytic reduction of camphor (both d- and ι-isomers); the optically inactive compound can be prepared by treating camphene with a 1:1 mixture of sulfuric acid and glacial acetic acid and then hydrolyzing the isobomyl acetat.
