摘要

本文对比研究了pH和酒精度对乙醇水溶液和薯干白酒辐照时过氧化物生成的影响。结果表明，乙醇水溶液辐照时，H,2,O,2,是唯一的过氧化物产物，酒辐照时产生两类过氧化物——H,2,O,2,和有机过氧化物。它们相对含量随pH而变化，在pH9—4范围内，H,2,O,2,占92%，有机过氧化物为8%。随pH降低，H,2,O,2,含量增加，有机过氧化物含量下降，至pH,<,2.5时，H,2,O,2,含量增至100%。实验求得0.2°酒精度（合0.2%乙醇，V/V）的乙醇水溶液中,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649847&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649849&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649848&type=,，在0.2°酒精度的酒中G（过氧化物）=2.9 ±0.2。当酒精度为57°（即含57%乙醇，V/V）时，乙醇的,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649850&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649851&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649866&type=,，酒的G（过氧化物）=3.6± 0.3。由于在很大浓度范围内辐照乙醇水溶液时没有有机过氧化物生成，这表明有机过氧化物不是由乙醇辐解形成，而为酒中其它有机组分的自由基所生成。

Abstract

The effect of pH and ethenol concentration on the formation of peroxide has been studied on the irradiation of liquor made from dried sweet potato and the aqueous solution of ethanol. Hydrogen peroxide (92%) and organic peroxide (8%)are produced when the liquor is irradiated in the range of pH from 4 to 9 but no organic peroxide at the pH less than 2.5 and in the aqueous solution of ethanol over a wide concentrations of ethanol. G(H,2,O,2,) and G(total peroxide) are equal to 3.6±0.3 and 2.9±0.2 for 0.2% (V/V) aqueous solution of ethanol and the liquor containing 0.2% ethanol and 4.3±0.1 and 3.6±0.3 for 57% aqueous solution of ethanol and the liquor (containing 57% ethanol), respectively. Over a wide ethanol concentration range, there is no organic peroxide in the irradiated aqueous solution of ethanol, it shows that organic peroxide does not formed from ethanol and it could result from the other composition radicals in the liquor.
