Effect of reaction time on ratio palm oil kernel based maltoside anomers / Terence Anak Stanley Mike Ajah

This research is written to study about synthesising and characterisation of synthetic glycolipids which are similar to alkyl polyglucosides (APGs) from palm kernel oil (PKO). Headgroup of glycolipids consist of dissacharides which are maltose and lactose. This research will focus on palm oil kernel based maltoside anomers with the effect of reaction time. This experiment is consist of three main steps which are acetylation, glycosylation and deacetyation. The characterisation of alpha and beta anomers will be determine by the principle on Nuclear Magnetic Resonance (NMR) Spectroscopy. Varieties of the glycosylation conditions prompted blends with various a/p ratio. The P-anomer is kinetically favourable. In this way a short glycosylation time and a moderate active catalyst, boron trifluoride (BF3), were connected to create more P-anomer than a-anomer. Then again, a stronger catalyst such as tin tetrachloride (SnC14), was utilized to deliver a-dominant products, which are thermodynamically more steady. Regardless of its unsaturation content, palm kernel oil acts comparative than saturated alkyl chains. A twenty four hours reaction with BF3 delivered 1:1 a/p proportion palm part oil lactoside. A slight P-prevailing (1:2) blend was acquired for maltoside with six hours response catalyzed by BF3. The virtue of the blends was around 70-90% because of a little amount of a result that demonstrated an extra H-l peak for both maltosides and lactosides.
