单糖与氯化钠模型反应中3-氯-1,2-丙二醇的形成
Formation of 3-Monochloropropane-l,2-diol in Thermal Reaction Model Systems Consisting of Monosaccharides and Sodium Chloride
摘要
Abstract
The formation of 3-monochloropropane-1,2-diol (3-MCPD) was investigated in thermal reaction model systems consisting of one of six monosaccharides,sodium chloride and deionized water.Temperature had the most significant influence on 3-MCPD formation from the "glucose + sodium chloride" model system,followed by sodium chloride concentration,reaction time and glucose concentration.In addition,3-MCPD could be formed from all six monosaccharides.The highest amount (30.604 μg/kg) of 3-MCPD was formed from the "ribose + sodium chloride" model system and the lowest amount (2.498 6 μg/kg) from the "fructose + sodium chloride" model system under the same reaction conditions.5-Hydroxymethyl furfural was the most abundant volatile compound detected from the "glucose + sodium chloride" model system,followed by furfural and 2,5-dimethyl acetyl furan.According to these results and the literature,the formation mechanism of 3-MCPD was discussed herein,and 3-epoxy-1-propanol (glycidol) was suggested to be as the key intermediate.关键词
