Parameter Optimization on Esterified Oil Palm Empty Fruit Bunch Cellulose (OPEFB) Pengoptimuman Parameter bagi Selulosa Tandan Kosong Kelapa Sawit (TKKS) Teresterifikasi
Chemical modifications of oil palm empty fruit bunch cellulose (OPEFBC) using ethylenediaminetetraacetic acid (EDTA) and acetic acid (AA) with different parameters were studied and optimized. At the initial stage, OPEFBC pulp was treated using four stages of bleaching stage (D-E-E-D) for production...

At the initial stage, OPEFBC pulp was treated using four stages of bleaching stage (D-E-E-D) for production of OPEFBC. Next, the OPEFB cellulose undergo esterification process using AA and EDTA under microwave assisted heating system to further enhance esterification. The influence of pre-treatment parameters on thermal stability and functional group changes were optimized using central composite design (CCD), response surface modelling (RSM) followed by thermogravimetric analysis (TGA) and functional group analysis (FT-IR).
