p-シメンの液相エマルジョン状酸素酸化において, 水層の初期pHを変え, 各pHにおけるp-シメンヒドロペルオキシドの生成限界濃度および反応率を求めた。また生成したペルオキシドを酢酸分解し,その生成物中に従来よく知られていたp-クレゾール, アセトン, クミン酸, p-メチルアセトフェノン, p-α-ジメチルスチレンの他にp-トリル酢酸を見出した。このことから, 今までに知られていたp-シメン-8-ヒドロペルオキシドおよび7-ヒドロペルナキシドの他に,9-ヒドロペルオキシドも少量ながら生成していることが推定される。

The Enantioselective Metabolism of p-Cymene in Rabbits.
p-Cymene (1) was metabolized in rabbits and the following four optically active metabolites, 2-(p-tolyl)-1-propanol (3': R/S = 65:35), 2-(p-tolyl)propanoic acid (5': R/S = 0:100), p-(2-hydroxy-1-methylethyl)benzoic acid (6': R/S = 91:9) and p-(1-carboxyethyl)benzoic acid (8': R/S = 30:70), were isolated in addition to three optically inactive ...
