Catalytic behaviour of sulphated zirconia supported on mcf as catalyst in selective glycerol esterification with palmitic acid to monopalmitin

Catalytic behaviour of sulphated zirconia supported on mcf as catalyst in selective glycerol esterification with palmitic acid to monopalmitin / Kishor Kumar A Murugan
Dalam kajian ini, superacid zirkonia sulfat, disokong dengan Mesocellular Foam (MCF) telah disediakan oleh kaedah urea-hidrolisis. Pengesteran antara gliserol dan asid palmitik telah dijalankan dengan kehadiran pemangkin ini dan bekalan berterusan nitrogen untuk membuang air terbentuk. Muatan pemangkin dan suhu bahan tindak balas telah dimanipulasi untuk mendapat keadaan yang paling sesuai dan optimum untuk tindak balas pengesteran. Semua tindak balas pengesteran dikaji dalam proses kelompok dan aktiviti pemangkin SZMCF di bawah pelbagai parameter tindak balas seperti muatan pemangkin (1 – 3 wt%) berkenaan dengan bahan tindak balas yang menghad (asid palmitik) dan suhu tindak balas (160-180 ⁰C) telah disiasat. Kesimpulannya, SZMCF pemangkin yang mempamerkan aktiviti yang baik adalah aktif dan sesuai untuk digunakan dalam tindak balas yang melibatkan molekul besar. _______________________________________________________________________________________________________ In this study, the sulphated zirconia superacid, supported on Mesocellular Foam (MCF) was prepared by urea-hydrolysis method. Glycerol and palmitic acid was esterified in the presence of this catalysts and continuous supply of nitrogen to remove water formed. Catalyst loading and temperature of reactants was manipulated to optimize the reaction condition for the esterification. All the esterification reactions were studied in a batch process and the activity of the SZMCF catalyst under various reaction parameters such as catalyst loadings (1 – 3 wt. %) with respect to limiting reactant (palmitic acid) and reaction temperatures (160 – 180 ⁰C) was investigated. As a conclusion, SZMCF catalyst which exhibited good activity was as an active catalyst and suitable to be used in the reaction involving bulky molecules.
