Acetaldehyde was removed from crude alcohol with an anion exchange resin (Amberlite IRA-400 and IRA-410) in the bisulfite form. The influence of acetaldehyde contents, concentration of alcohol, flow rate and height of anion exvhanger for removal of aldehyde was investigated. The optimum condition was as follows : acetaldehyde contents 2〜3 mg. per 100 ml, concentration of alcohol 60%, flow rate 1.5〜2.0 ml per min, anion exchanger 15 mm dia ×600 mm height. Generally, amberlite IRA-410 was superior to IRA-400 because of larger capacity of bisulfite absorption. Overflowing method was more effective than dropping method. The deteriorations of alcohol quality were also investigated with respect to the solubility of resin and the BARBET reaction. No deteriorations of quality were observed by passing the alcohol through an anion exchange column, but dissolution of resin in alcohol up to approximately 10% and an increase in aldehyde were observed after steeping the resin in alcohol for a week. This purification apparatus may be set up between the condenser of mash colmn and rectifying column.
