Hidrolisis Hasil Delignifikasi Tandan Kosong Kelapa Sawit dalam Sistem Cairan Ionik Choline Chloride

Abstract

This research aims to determine the hydrolysis of delignification results on palm empty fruit bunches and determine the best conditions of hydrolysis obtained in the hydrolysis process in the choline chloride ionic liquid system. The main raw material used is cellulose delignification results TKKS, choline chloride, sulfatl acid, and distilled water. The hydrolysis stage in this research was carried out at temperature 105 0C, concentration of catalyst (H2SO4) 10% (w / w) cellulose, the amount of ionic liquid 10%, 15%, and 20% (w / w) cellulose and it was stirred at constant speed 120 rpm with a reaction time of 30, 60 and 90 minutes. The results showed, in the hydrolysis stage was obtained using an ionic liquid glucose . LUFF method analysis showed the purity of the resulting hydrolysis is equal to of 37.96% with the best reaction time, the optimum conditions was obtained in reaction time 90 minutes and the amount of choline chloride 20%.
