P05 超音波霧化による有機物質-エタノール混合水溶液の濃縮分離

抄録

Ethanol and organic material mixed aqueous solution were atomized using ultrasonic irradiation at 2.4 MHz. Atomized liquid was collected by refrigeration of liquid nitrogen. The concentrations in collected liquid and mist were experimentally investigated. Malic acid, lactic acid (organic acid), 1-propanol, methanol (alcohol), methyl ethyl ketone, diethyl ketone (ketone) were used as organic material. The ethanol concentration in collected liquid was little affected by addition of organic materials. Organic acid in ethanol aqueous solution was not separated. On the other hand, alcohol and ketone concentrations in collected liquid were higher than those in sample. The 1-propanol concentration in collected liquid was lower than that in mist. This is because it is difficult to collect nano-sized droplets which contain highly condensed alcohol.
