抄録

Metal (II) ion-exchanged 5A, Y, and X type zeolites were screened to find effective catalysts for oxidative cleavage of palm stearin into mono- and dibasic acids with middle carbon chains.<BR>The formation of carboxylic acids was followed by 1H NMR spectrometry. When one reaction was recognized to form volatile material more than the others, it was carried out on a larger scale to collect the volatile material. This material was submitted to GC-MS spectral analysis for identification of individual components.<BR>The formation of carboxylic acid was confirmed in the case of products obtained by catalysts such as Mn (II) -5A and Co (II) -Y, but the amount of each was quite small. Analytical results on the volatile materials showed Mn (II) -5A and Co (II) -Cu (II) -Y to contribute to the formation of carbo-xylic acids and aldehydes, respectively.
