- 中文摘要: The kinetics of the sulfaction of 2-octanol by sulfamic acid in dimetylformamide were studied. The rate of disappearance of sulfamic acid obeys the rate equation: Rate=k[SA] where [SA] is the concentration of sulfamic acid. The energy and entropy of activation are 3.1.plmin.2eu. A posible mechanism is as follows: The sulfamic acid reacts with DMF to form DMF.bcdot.SO/sub 3/ which then reacts rapidly with 2-octanol to form ammonium sec-octyl sulfate.The kinetics of the sulfation of 2-octanol by sulfamic acid in dimethyl sulfoxide were also studied. The reaction is described by a similar first-order equation. The energy and entropy of activation are 33.7.plmin.1.0kcal/mol and 17.plmin.3eu.
