Questions: 1. One mole of a compound A‚ with vapor pressure 400mmHg at 50oC‚ mixed with 3 moles of compound B‚ with vapor pressure 480mmHg at 50oC to form a homogeneous solution. What is the vapor pressure of mixture at 50oC? XA =moles of A\total No. of moles XA =1\4 XB=3\4 Ptotal=PAoXA+PBoXB =400*1\4 + 480*3\4 = 460mmHg 2. Why should a distilling flask be filled not less than 1\3 filled or more than 2\3 full? This is to allow the liquid being heated room to expand as it turns

Steam distillation of cloves produced 0.53g of an oil which contained in its IR spectrum the functional groups O-H (at 3520 cm-1)‚ sp2 C-H (3080 – 3000 cm-1)‚ aliphatic C-H (2980 – 2940 cm-1)‚ and both alkene C=C (at 1640 cm-1) and aromatic C=C (at 1514 cm-1). The IR spectrum is attached to this report. These data are consistent with the structure of eugenol‚ shown in Figure 2 below: In addition‚ the IR of the product from the steam distillation of cloves closely corresponds with that of an

Computation of the Fractional Fourier Transform Adhemar Bultheel and H´ctor E. Mart´ e ınez Sulbaran 1 Dept. of Computer Science‚ Celestijnenlaan 200A‚ B-3001 Leuven Abstract In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that filters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform

Determination of Melting and Boiling Point of different Organic Compounds Bakare‚ Abimbola Kristine‚ C. Professor Miranda Marilyn‚ school of chemical engineering and biotechnology‚ Mapua Institute of Technology‚ CHM145L-B11 ABSTRACT A melting point of a solid is the temperature at which the first crystal just starts to melt until the temperature at which the last crystal just disappears. Thus‚ the melting point (m.p.) is actually a melting range. The melting point of a substance depends

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

Heat exchange is among the most important activity for crude distillation units. The 2nd part of the report focuses on this heat exchange process occurring in the crude distillation unit of Guwahati refinery. Necessary data regarding all the heat exchangers has been provided in a tabular manner to make understanding

Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The product obtained by distillation‚ is termed

Experiment 1: Simple Distillation and Boiling Points- Separation of Liquids February 24‚ 2014 Analysis In this experiment‚ the distillation of three groups of two miscible liquids was performed. First‚ Ethanol and 2-Propanol were distilled. The boiling points of ethanol and 2-propanol had a difference of 5°C. The percent recovery for both ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient
