Abstract

Nyamplung oil originated from Ujong Pancu, Aceh Besar is one of the vegetable oil sources which is not fully utilized yet. The extraction of nyamplung oil is done using soxhletation with n-hexane solvent; during this process, the oils produced is at the 55.55% levels. The product is in the form of yellowish green liquid with the density of 0.88gr/ml. The nyamplung oil extract has the iodine number of iod 83.53 mg iod/g and hydroxyl number of  64.292 mg KOH/gram which can be utilized as the raw material in making polyurethane membrane. Polyurethane membrane is synthesized by reacting fatty acids from nyamplung seed oil with hexamethylene-1.6-diisocyanate (HDMI). The ration of the oil towards HDMI is variated as, 5:1;5:3;5:5;5:7;5:9 v/w. The membrane has a composition of  5:7 v/w  with 90-100 oC polymerization temperatures and  160oC curring temperature for 8 hours is hard, homogenous and quite elastic with a transparent brown colour.

Abstract

This research aims to synthesize polyurethane membrace from avocado seed oil as a source of hydrixyl (-OH) and hexametylhene -1.6-dissocyanate (HDMI) as a source of isocynate (-NCO). The oil were extracted from avocado seeds at temperature of  60-80oC for 2 hours using n-hexane solvent. The results of FTIR spectrum analysis from avocado seed oil showed that there were -OH clusters absorption on the wavelength number of 3393.819 cm-1, thus this oil can be used to synthesize polyurethane membrane. The isocyanate composition, time and temperature during synthesis process of polyurethane membrane were varied. The polyurethane membrane were moulded in petri dishes, then heated up for 48 hours on the temperature of  70oC, and finally taken out from its mould. The characteristics of the polyurethane membrane from avocado seed oil are brown in colour, homogenous, elastic, solid, transparent and shaped like a membrane. The measurements from FTIR spectrum showed that the -NCO clusters are no longer present. This condition happened because there were no more absorption in the wavelength number of  2270 cm-1 . It can be concluded that the isocyanate has completely reacted during polymerization and the curing process, thus urethane was created in the 1699,965 cm-1 absorption which was the urethane C=O clusters absorption.
