| Separation of Nitrophenols | | | | Abstract: Using a micro scale steam distillation we separated ortho and para-nitrophenol from a mixture that was already made. After the para and ortho were separated we measured their melting points and compared it to the literature values for purity. For ortho-nitrophenol we had 60% recovery and for para 160% recovery. Our melting point ranges were ortho: 45-46°C and para 64-95°C. Introduction: Nitration: In phenols‚ -OH group strongly

Group 3 Experiment 1 Simple Distillation of Vodka Ancell Julienn C. Cruz Department of Pharmacy‚ Faculty of Pharmacy University of Santo Tomas‚ Espana Street‚ Manila 1008 Date Submitted: July 5‚ 2012 Abstract Distillation is a process of converting a liquid to a vapor‚ and then‚ collecting the distillate in another container. There are four distillation methods which are fractional distillation‚ simple distillation‚ vacuum distillation and steam distillation. The methods used here are

technique‚ identify the components by their retention times‚ and compute for the concentration and percentage content of each component by their peak areas and peak heights. The volatile oil from eucalyptus leaves was isolated with the use of steam distillation setup‚ then using a separatory funnel to pipette out the extract from the distillate. A gas chromatography‚ with nitrogen gas as the carrier gas and a flame ionization detector‚ was used to separate and characterize the components of the essential

Isolation of Essential Oils by Steam Distillation Procedure Part A Apparatus 1.) Using a 20- or 25-mL round-bottom flask (for distillation) and a 10-mL round-bottom flask (for collection) assemble a distillation apparatus 2.) Use an aluminum block to heat and insert a water condenser 3.) The collection flask may be immersed in ice to ensure condensation of the distillate Preparing the Spice 1.)
