| description | <p>A benign process, non catalytic transesterification in sub and supercritical methanol method was used<br />to prepare biodiesel from vegetables oil. The experiment was carried out in batch type reactor (8.8 ml<br />capacity, stainless steel, AKICO, JAPAN) by changing the reaction condition such as reaction<br />temperature (from 210°C in subcritical condition to 290°C in supercritical state with of 20°C<br />interval), molar ratio oil to methanol (1:12-1:42) and time of reaction (10-90 min). The fatty acid<br />methyl esters (FAMEs) content was analyzed by gas chromatography-flame ionization detector (GCFID).<br />Such analysis can be used to determine the biodiesel yield of the transesterification. The results<br />showed that the yield of biodiesel increases gradually with the increasing of reaction time at<br />subcritical state (210-230oC). However, it was drastically increased at the supercritical state (270-<br />290oC). Similarly, the yield of biodiesel sharply increased with increasing the ratio molar of soy oilmethanol<br />up to 1:24. The maximum yield 86 and 88% were achieved at 290oC, 90 min of reaction time<br />and molar ratio of oil to methanol 1:24, for soybean oil and palm oil, respectively.</p><p>Proses transesterifikasi non katalitik dengan metanol sub dan superkritis,<br />merupakan proses yang ramah lingkungan digunakan untuk pembuatan biodiesel dari minyak nabati.<br />Percobaan dilakukan dalam sebuah reaktor batch (kapasitas 8,8 ml, stainless steel, AKICO, JAPAN),<br />dengan variabel kondisi reaksi seperti temperatur reaksi (dari kondisi subkritis 210°C-kondisi<br />superkritis 290°C dengan interval 20°C), rasio molar minyak-metanol (1:12-1:42) dan waktu reaksi<br />(10-90 menit).
