Abstract	In this report, high pressure hydrogenation oE pelargonic acid to produce nonyl alcohol is studied. The hydrogenation catalyst usecl is copper-chromiiim promoted with bariuna, which is prepared by the method recommended by Adkins. The samp{e pelargonic acid is obtained as a by-product of destructive oxidation of oleic acid with ozone to produce dibasic acids. The sample contains ca. 5% of caproic acid and some of its properties are as fo11owing: Dge O. 9131, A.V. 361.4, over 90% o£ sampie boils at 1150 C/3 mrznHg. The hydrogenation experirnents are performed over the temperature range of 280tv 3600C, under initiai hydrogen pressure of ca. 120 atm. in the presence of the above said catalyst (5 rhvlO% of sample), 1)y using a 2 liters rotary autoclave. The reaction time is 1・一v2 hr. Under optlrnuin conditions, nony1 alcohoi is produced in the yield of over 80%, which is separated from the reaction produc{’s and identified. The influences of reaction temperature, reaction time and the amount of catalyst are fully observed and discussed. Higher reaction ternperature promotes alcohol production, but it causes, at the same time, excessive hydrogenation to produce parafi}n hyclrocarbons such as nonane. Longer reaction time has the sarne ef’te’ects. The increase of catalyst amount is very efl”ective for the promot.ion of the alcohol yie1d. Under too mi1d reactioR conditi6ns, consider.able aniount of esters (mainly nonyl pelargorate) is found in the reaction products. But under proper reaction circumstances the ester decomposition (to prodtece alcohol and aci.d) and hydrogenation of the 118 大塚博・高田善之・富田宣・飯尾賢二・神野政昭・大宮法和 2 acid (to produce alcohol) are, supposed to become predominant over the ester formation.
