【 摘 要 】

Epoxide compound is made by reacting Kapok Oil with acetic acid and hydrogen peroxide with in situ method. The epoxidation reaction was varied at temperatures of 60 °C, 70 °C and 80 °C, while the time of reaction time was varied at 15 minutes, 30 minutes, 60 minutes and 90 minutes. The reaction rate coefficient for the epoxide was obtained as . The addition of the epoxide compound 0.5 w/w in the formulation of SLS was able to reduce the IFT value up to 9.95 x 10-2m N/m. The addition of co-surfactant (1-octanol) was varied between 0.1 and 0.4 of the total mass of the main formulation (SLS + epoxide + water formation). The smallest interfacial tension value is obtained on the addition of co-surfactants as much as 0.2 w/w, with the IFT value is 2.43 x 10-3m N/m. The effectiveness of the chemicals was tested through micro displacement using artificial porous medium. The experimental results show that some chemicals developed in the laboratory can be used as EOR chemicals. The oil displacement experiments show that as much as 20 to 80 of remaining oil can be recovered by flooding it with the chemicals. The results also show that the oil recovery depends on type of chemicals and chemical concentration.
