p-Menthan-3,8-diol (PMD): Tổng hợp, tinh chế và phân tích đặc điểm phổ của các đồng phân

p-Menthane-3,8-diol (PMD) was synthesized from (±)-citronellal via Prins cyclized reaction using sulfuric acid as catalyst with high yield (H = 78.5%). cis/trans PMD isomers were isolated with purity over 99%. From analysing IR and NMR spectra of cis isomers, trans isomers and mixture of them, some methods of determining cis/trans PMD ratio in the mixture are proposed.
Keywords: PMD, citronellal, geometric isomer, IR.
