Thirteen samples of used motor oil and 33 recycled fractions, obtained in the laboratory by means of a recovery process similar to that currently used in Italy (vacuum distillation followed by thermal clay treatment) were examined. The Ames test (standard and modified version according to Blackburn)

The fourth most volatile 2.5% molecular distillate of butteroil obtained by redistillation of the most volatile 10% cut was examined by gas chromatography on a polar capillary column (RSL-300) with electron impact and chemical ionization mass spectrometry. For this purpose the distillate was first f

A decrease in absorbance at 340 nm, at rates similar to those obtained with alcohol dehydrogenases in routine assays, occurred when NADH or NADPH was mixed with acetaldehyde that had been exposed to air for various durations. NAD(P)H was apparently oxidized by interfering substance(s) present in ace

回分式蒸留機の蒸発缶に醪を張り込んで加熱する時，蒸発缶から発生する蒸気の一部が蒸留機内で凝縮して生じる分縮液を蒸発缶には流入させず，別に設けた再留缶に流入させ，蒸発缶液のアルコール濃度が予め定めた濃度以下となった時，蒸発缶の加熱を停止し，以後は再留缶に溜まった分縮液を加熱して蒸留する方法について検討した。1. 16.0vol%エタノール水溶液を原料として蒸留し二缶式蒸留機の基本的な機能を検討した。 …
