Abstract

In this study ethyl lactate synthesis was performed in a membrane reactor at 303, 313, 323 K temperatures and 1:1, 3:1, 6:1 alcohol:lactic acid initial feed molar ratios. Effects of temperature and initial feed molar ratio on acid conversion and separation performance were investigated. Membranes were characterized by using scanning electron microscope (SEM) and atomic force microscope (AFM). In order to obtain the performance of membrane reactor system, reactions were also carried out in a batch reactor. While 0.26 acid conversion was obtained in batch reactor at equal molar ratio and 323 K, 0,62 conversion was achieved in membrane reactor at the same conditions.

Özet

Bu çalışmada, laktik asit esteri olan etil laktatın, çevre dostu proses olarak nitelendiren, membran biyoreaktör ile üretimi 303, 313 ve 323 K sıcaklıkta, 1:1, 3:1, 6:1 etanol:laktik asit molar reaktan besleme oranı ile gerçekleştirilmiştir. Sıcaklığın ve molar besleme oranının reaksiyon dönüşümüne ve ayırma performansına etkisi incelenmiştir. Membranların karakterizasyonunda taramalı elektron mikroskopu (SEM) ve atomik güç mikroskopu (AFM) kullanılmıştır. Sistem performansını belirlDuremek amacıyla, reaksiyonlar aynı koşulda kesikli reaktörlerde de yapılmıştır. Eş molar beslemede, 323 K sıcaklıkta, kesikli reaktör ile 0,26 laktik asit dönüşümü elde edilirken, önerilen çevreci sistem ile 0,62 dönüşüm değeri elde edilmiştir.
