Abstract

POTENTIAL OF SULFATET ALUMINA-HETEROGENEOUS ACID CATALYST IN ESTERIFICATION RUBBER SEED OIL. Two tipe of catalysts have been synthesed and evaluated ( free fatty acid conversion) in esterification of rubber seed oil. The first and the second catalyst have content SO₃8,821 % and 40,715 %, respectly. The optimum condition of reaction studied : volume ratio methanol/oil 0,9-1,8 v/v; catalyst concentration 1,67-10 % wt/v; time of reaction 1-7 hours and temperature of reaction 50-70 ^oC. This study showed, the second catalyst more active than the first catalyst. Maximum conversion from esterification reaction of rubber seed oil of the first and the second catalyst are 75 % and 97 %, respectly. The optimum condition of reaction achieved at volume ratio methanol/oil 1,8 v/v; catalyst concentration 1,67 % wt/v; time of reaction 7 hours and temperature of reaction 70 ^oC.

Keywords: sulfated alumina, free fatty acid, eterification, rubber seed oil.

Abstrak

Dua tipe katalis alumina tersulfatasi telah disintesis dan dievaluasi kinerjanya (berupa konversi Asam Lemak Bebas, ALB) pada reaksi esterifikasi asam lemak bebas minyak biji karet. Katalis tipe 1 dan tipe 2 berturut-turut memiliki kandungan SO₃ 8,821 % dan 40,715 %. Kondisi optimasi reaksi yang dipelajari: rasio volume metanol/minyak 0,9-1,8 v/v; konsentrasi katalis 1,67-10 % b/v; waktu reaksi 1-7 jam dan temperatur reaksi 50-70 ^oC. Hasil penelitian menunjukkan katalis tipe 2 lebih aktif dari tipe 1. Konversi ALB maksimum dari reaksi esterifikasi minyak biji karet dengan katalis tipe 1 dan tipe 2 berturut-turut 75 % dan 97 %. Kondisi optimum reaksi tersebut dicapai pada rasio volume metanol/minyak 1,8; konsentrasi katalis/minyak 1,67 % b/v; lama reaksi 7 jam dan temperatur reaksi 70 ^oC.
