ABSTRACT.

Liquid crystals are fluids that are between the solid and conventional liquid phases. Liquid crystals are in widespread use, especially in optical technologies. They are synthesized by combining fatty acids with cholesterol: This study aims to utilize coconut oil as an alternative source of fatty acids for synthesizing liquid crystals since coconut is cheap and abundant in the Philippines. Coconut oil is eighty-five percent fatty acids. This study used commercial coconut oil. Sulfuric acid was used to liberate the fatty acids. When the fatty acid layer was collected, it was mixed with the catalysts DCC (C71-112N2,N, N-dicyc/ohexylacarbodiamide) and DMAP (C71-110N2, 4-dimenopyrimidine) in 1:1 ratio. This was then mixed with commercial cholesterol and stirred until precipitates formed. The precipitates were filtered and the filtrate was collected. The organic layer was separated from the filtrate. The liquid crystal component was determined and isolated through column chromatography and thin-layer chromatography. Infrared (IR) spectrography confirmed the presence of cholesterol ester. Two melting points, 80°C and 110°C, further showed that the product had liquid crystalline properties. The success of this project will provide a cheaper alternative to costly commercial liquid crystal and yet another use for coconut oil. Continue reading HERE……..
