METHODOLOGY

3.1 LOCATION OF STUDY
The experiment of producing oil extraction from RSO will be conducted at Universiti Teknologi Mara Puncak Alam.
3.2 MATERIALS AND EQUIPMENTS
3.2.1 RUBBER SEED
The rubber seed were obtained from LGM, Kuala Lumpur, Malaysia and were stored room conditions.
3.2.2 CHEMICALS
Oil was extracted with n-hexane solvent using Soxhlet apparatus.
3.2.3 EQUIPMENTS AND APPARATUS
Equipment used in this experiment is Soxhlet apparatus. The apparatus of Soxhlet extraction including condenser, tubes, Soxhlet chamber, round bottom flask and heating mantle were set up for solvent extraction. In addition, oil recovery method was done using a rotary vacuum evaporator. Other equipments used including oven and 0.5mm sieve were used for seed preparation.

3.5 SOLVENT EXTRACTION PROCESS
First, 10g of the RSS were transferred into a thimble. At the same time, 150mL of solvent was poured into the round bottomed flask. Then, Soxhlet were heated using heating mantle. The oil was recovered from the solvent by evaporation of the solvent in a rotary vacuum evaporator under reduced pressure. The mixture of the oil and excess solvent was poured into a weighed round bottomed flask. The flask was fitted to the rotary evaporator and immersed in the heating medium until all the mixture was totally immersed. The temperature of the rotary evaporator was set slightly above the boiling point of the solvent. Then, the mixture was rotated slowly to prevent the mixture to evaporate out from the instrument. The vacuum pump was switched on to suck the evaporated volatile solvent. After 30 minutes of evaporation, the heating system was switched off and left to cool down for another 30 minutes. Finally, the flask was weighed and the concentrated extract was taken out.
