- ABSTRACT Blod/esel synthesis by transesterlflcation reaction of coconut 011with methanol by using ash of palm empty fruit bunches (EFB) as base catalyst has been conducted. Sample of ash was prepared through heating, screening, reashlng, and finally determining of potassium content. Sample of coconut 011was analyzed by GC-MS. A cel1aln amount of ash was extracted In methanol with mixing for about 1 h at room temparature and a result was used for reaction of transesterlflcatlon. The studied variables wera effect of temperatura and speed of stirrer. The composition of the methyl esters (blodlesel)was analyzedusing GC-MSand 1H NMR, whereascharactersof blod/eselwere analyzed using ASTM methods. The results showed that potassium content In ash of EFB could be extracted by methanol and It could be used as base catalyst In the blodlesel synthesis. The value Increasing of both variables enhanced the blodlesel conversion. The propel1les of blodlesel were relatively conformed to specification of blod/ese/.
