The title compound was synthesized via acylation between 4 substituted-phenylacetic acid and resorcinol gives the corresponding 1 -(2,4-dihydroxyphenyl)-2-(4substituted-phenyl)ethanone. The intermediate was then cyclized to give 3-(4-substituted-phenyl)-7hydroxy-4H-chromen-4-one. Alkylation of the second intermediate with the 1,6 -dibomohexane yield the 1 desired compound. The structures of intermediates were elucidating through FT - IR and H-NMR spectroscopic techniques. 210 3rd ICYC 2010 Universiti Sains Malaysia 23rd-25th June 2010 ORAL PRESENTATION (PHYSICAL) PHY-O1 ISOTROPIC AND LIQUID CRYSTALLINE BEHAVIOR OF PSEUDO TERNARY PHASE OF PALM KERNEL OIL ESTER, WATER AND NON-IONIC SURFACTANTS SYSTEMS 1 Elrashid S.M., M.H.F.Sakeena, Ghassan Z.A., Muthanna F.A., Munavvar A.S. and Azmin M.N. 1 1 1 1 2 1 Department of Pharmaceutical Technology, School of Pharmaceutical Sciences, Universiti Sains Malaysia, 11800 Pulau Pinang, Malaysia 2 Department of Physiology, School of Pharmaceutical Sciences Universiti Sains Malays ia, 11800 Pulau Pinang, Malaysia E-mail: [email protected] The palm oil is the leading agricultural product of Malaysia. Palm Kernel Oil (PKO) is type of Palm Oil obtained from the palm fruit nut. The PKO is composed mainly of saturated lauric fatty aci d myristic acid and unsaturated oleic acid. Its unique composition makes it versatile in various fields of application. Research bodies in Malaysia, Malaysia Palm Oil Board (MPOB), Palm Oil Research Institute of Malaysia (PORIM) and Universiti Putra Malaysia (UPM) are modied PKO in to Palm Kernel Oils Ester (POEs) having improved properties and new applications The phase behaviors of this PKOEs with blend of low and high HLB blends of nonionic surfactants Tween 80 (T80), Span 80 (S80) with water was studied using water titration method. Various ratios of couple of surfactants T80/S80 in...
