|p-Menthane-3,8-diol Usage And Synthesis|
P-menthane-3,8-diol is a p-menthane monoterpenoid in which p-menthane carries hydroxy groups at C-3 and C-8. P-menthane-3,8-diol derives from a hydride of a p-menthane.
p-Menthane-3, 8-diol, also known as para-menthane-3, 8-diol and PMD, is an active ingredient used in insect repellents. p-Menthane-3, 8-diol smells similar to menthol and acts as a coolant.
p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an active ingredient used in insect repellents. It smells similar to menthol and has a cooling feel. There are eight possible isomers of p-Menthane-3,8-diol, and the exact composition is rarely specified and is commonly assumed to be a complex mixture.
|Chemical Properties||p-Menthane-3,8-diol has a faint minty, herbaceous, eucalyptus-like odor. The cooling power is reported to be approxi mately 9.5 times that of (-)-menthol.|
|Occurrence||Reportedly present in the lemon eucalyptus plant(Eucalyptus citriodora tree), which is native to Australia, but is now cultivated in many warm places around the world.|
|Preparation||In a patented method, citronellal is treated with aqueous sulfuric acid to produce p-menthane-3,8-diol. Also produced by an extraction process utilizing lemon eucalyptus oil.|
