found by weighing the watch glass with the filter paper and subtracting the total from the original weight. The TLC test was conducted by placing sample products on a TLC plate. Next‚ the plate was put in solvent mixture of 80% heptane and 20% ethyl acetate. The solvent mixture was allow to rise ⅔ the height of the plate and then placed under UV light to observe the distance the samples traveled. The ferric chloride test was administered by placing 1 mL of ethanol and 1 drop of 1% by mass ferric chloride

mantle in a round-bottom flask. A direct stem distillation took place‚ and the oil product was out aside for a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment did not proceed to that step due to the incorrect amount of NaOH. Introduction The isolation of eugenol from cloves is isolated from ground cloves using the technique of steam distillation‚ which is often used to isolate liquid natural

Biotechnology‚ Mapua Institute of Technology [pic] ABSTRACT The purpose of this experiment is to prepare cyclohexene form cyclohexanol‚ and know the properties of alkene. The first part of this experiment is preparation of cyclohexene. Simple distillation set-up is assembled. (See Figure 1). Exactly 6.0mL of cyclohexanol is weighed in a quick-fit one-necked pear shaped flask. 1.50mL of 85% H3PO4 is measured using the 2mL pipet and added to the weighed cyclohexanol. Another 0.25mL of concentrated
