Abstract


Glukosa banyak dimanfaatkan untuk proses dekomposisi dan menghasilkan beberapa senyawa anorganik, dalam penelitian ini salah satu produk yang di hasilkan dalam produksi dekomposisi glukosa adalah HMF (5-hydroxymethyl-2-furaldehyde). Penelitian ini bertujuan untuk mempelajari proses dekomposisi glukosa pada tekanan dan temperature tinggi dimana tekanan dibuat konstan 10 atm dengan bantuan gas nitrogen sedangkan temperature berkisar antara 140-180 °C. Pengaruh konsentrasi asam sulfat dipelajari untuk mengetahui aspek kinetika. Dari penelitian ini didapat dekomposisi glukosa mengikuti orde satu dengan 5-HMF sebagai produk paling banyak sedangkan harga energi aktivasi didapat paling besar 1426.68 J/mol pada komsemtrasi asam sulfat 0.4 N dan konsentrasi HMF paling banyak didapat pada suhu 180, waktu 40 menit sebesar 0.00949 mol/L dengan konsentrasi asam sulfat sebesar 0.4 N.
