酸可分解型非离子表面活性剂在酸性溶液中分解反应动力学的研究

Study on Kinematics of Analysis Reaction of Nonion Surfactant that can be Decomposed by Acid in the Acidic Solution

非离子表面活性剂 12 80 0、14 80 0、1680 0在酸性溶液中分解成的羰基化合物是甲醛。可用乙酰丙酮比色法测定 .实验结果表明 :它们在 0 .1mol/LHCl溶液中的分解反应是准一级反应 .3小时以后 ,它们的分解率均大于 90 % .其中 ,12 80 0几乎 10 0

Nonion surfactant 12800?14800?16800?can be decomposed into formaldehyde a type of carbonyl compound in acidic solution, which can be measured with ACAC. Colorimetric method. Results show: The decomposition reaction in 0.1 mol/L HCl solution is the first order reaction. The decompositon rates are all more than 90% after 3 hours and the rate of 12800 is almost 100%.
