Abstract

REACTION KINETIC MODEL OF RBD PALM OIL BASED-POLYOL PRODUCTION. Polyol, a raw material of polyurethane, has successfully been produced from a renewable resource namely RBD palm oil. This polyol was made by firstly adding a peroxyacetic acid formed in situ from H₂O₂ and CH₃COOH with H₂SO₄as cataliyst into RBD palm oil to form epoxidized RBD palm oil. The epoxidized palm oil then was added to a mixture of methanol (MeOH), isopropanol (IPA), and H₂SO₄for 2 hours at 60^oC so that palm oil-based polyol was formed. The main equipment used in this research was a 500 mL three necked flask, equipped with a reflux condeser, thermometer, water bath and magnetic stirrer. The product was analysed using a titration method and Infra Red (IR) Spectroscopy. It was obtained that the produced palm oil-based polyol has a value of hydroxyl number of 150-209 mg KOH/g sample and a viscosity of 740.777 cP. These results are in accordance with other polyol products from other sources. The kinetic of palm oil-based kinetic was studied and the best model of the reaction rate equation was where k’ = 3.399 e^-2391.,6/RT. The unit of k is L² mol^-2 menit^-1. The average error of the equation is 4,549%.

Polyol, bahan baku polyuretan, telah berhasil dibuat dari bahan baku terbarukan yakni polyol berbasis RBD palm olein. Polyol ini mula-mula dibuat dengan menambahkan asam peroksi asetat yang dibentuk secara in situ dari H₂O₂danCH₃COOH dengan katalis H₂SO₄kedalam RBD palm olein untuk membentuk RBD palm olein terepoksidasi. RBD palm oil terepoksidasi ditambahkan kedalam campuran metanol (MeOH), isopropanol (IPA) dan sejumlah katalis H₂SO₄selama 2 jam pada suhu 60 ^oC sehingga terbentuk polyol berbasis RBD palm oil.
