| 摘 要： | 为开发环保水解工艺,在不使用任何无机酸和无机盐的情况下,利用介质阻挡放电等离子体进行淀粉的水解实验,在酸性等离子体作用下,淀粉水解为葡萄糖和二糖,其转化率达61.2%,质量选择性为34.0%.分析发现放电过程中形成的质子层有很强的酸性,是理想的酸催化剂.由此提出等离子体酸概念,并讨论了其优点和应用前景.该等离子体酸可应用于大量的酸催化反应.

| Abstract: | A novel plasma hydrolysis of starch was developed by using dielectric barrier discharge plasma. Monosaccharide and disaccharide were obtained directly from starch without any acids or enzymes. The conversion of starch is 61.2% with the selectivity for oligosaccharides as 34.0%.Further analysis shows that a proton layer is formed in the steam plasma.This proton layer is an excellent catalyst for hydrolysis reaction since it exhibits strong acidity.The concept of plasma acid is presented to describe the acidic property of plasma.The environmentally friendly plasma acid can be applied in many acid-catalyzed reactions. |
