The Investigation Of Preparation Of Formic Acid By The Hydrolysis Of Methyl Formate

This thesis makes the focal points on the process through which Formic Acid (FA) is made from the hydrolysis of Methyl Formate (MF), gives a detailed discussion on the dynamics of the reaction. And then meliorates the operation condition bases on the experiments.The author set up a new modified equation for the quantitative analysis of the hydrolysis compounds chromatogram. In the dynamical reaction of the hydrolysis of MF, the conclusion that the temperature of reaction does not tamper with the equilibrium constant (K) but the reaction rate is employed. The reaction is going rapidly at temperature of 120. In the other way, the K will decrease when the reactor methanol rises in the initially system.The mechanism of hydrolysis reaction is educed. Therefore, the equation of the reaction dynamics is worked out bases on that. According of the experiments data, the math equation is made and the parameter can be confirmed. It gets the dynamicsequation of the hydrolysis reaction: It can beused in industrial process. And according to the Arrhenius Equation, the other parameter of thermodynamics can be calculated. The activation energy (Ea) is quantified that Ea=70.74KJ/mol. The constant of reaction rate (k) vs the temperatureformula is also made that In the technological operation experiment, the condition is 120 H₂O : MF = 2 : 1 and pressure of the saturated vapor of the reactant under the above temperature is 0.95MPa, the result is that the time of reaction balance is 40 min, the transform ratio of MF is 38.51% the equilibrium constant (K) is 0.2343. Under these conclusions, the author designs the continuous operating process of hydrolysis reaction. It can make it realized that the output of reformed product line can be increased 3 or 4 times than before.
