Abstract

Bu bilimsel çalışmada, etilasetatın hidroliz
reaksiyonu tepkime mertebesinin ne olduğunu, farklı sıcaklıklarda hız sabitini
ve aynı zamanda aktivasyon enerjisini ve frekans faktörünü kesikli bir reaktörde
test etmek için gerçekleştirildi. Bu amaçla, bu hidroliz reaksiyonu, kesikli
bir reaktörde farklı sıcaklık aralığında (283-313 K) zamana bağlı NaOH tüketimi
ile deneysel olarak gerçekleştirildi. Sonuçlar etil asetatın hidrolizinin
tersinmez ikinci dereceden bir reaksiyon olduğunu göstermektedir. Deneysel
verilerin analizi, aktivasyon enerjisinin 29.775 kJ mol^-1 ve frekans
faktörünün 27038 olduğunu gösterdi.

Determination of the Expression Rate of Ethyl Acetate Hydrolysis Reaction Depending on the Temperature

Abstract

In this scientific
study, the hydrolysis reaction was carried out in a batch reactor to test which order of the reaction is, the rate constant at different temperatures and also,
activation energy, and frequency factor.
For this purpose, this hydrolysis reaction was experimentally performed the
time-dependent NaOH consumption in a
batch reactor in the different temperature range (283 K-313 K). The
results show that hydrolysis of the ethyl acetate is a forward one-way second order reaction. The analysis of the experimental data showed
that the activation energy is 29.775 kJ mol^-1 and frequency
factor 27038.

Keywords
