蔗糖转化速率常数与酸浓度关系方程的确立
ESTABLISHMENT ON THE RELATIONSHIP BETWEEN THE RATE CONSTANT OF SUCROSE INVERSION REACTION AND ACID CONCENTRATION
【摘要】 蔗糖酸催化转化反应速率常数k,一些文献认为是一个复合常数,本研究应用实验的k与CH+关系数据作图时,发现k与CH+为指数关系。分别用HCl和H2SO4作催化剂,用作图法分别求得两组kH+,n值和k与CH+关系方程。经验证,所得的结果与文献值相当吻合。
【Abstract】 In some references, the rate constant k of sucrose inversion reaction was a compound constant. In this paper, HCl and H2SO4 were used as catalyst in sucrose acid hydrolysis reaction respectively. The results showed that the relationship between the rate censtant k and acid concentration CH+ was exponential. The values of k0,, kHCl and kH2so4 in this paper were consistent with those in references.
