SIMPLE DISTILLATION OF VODKA (ANTONOV) Kristel Joy M. Tan‚ Joshua Michael L. Torres‚ Pauleen Anne S. Vanadero‚ Paulene Arielle P. Ynzon and Rachel Pauline E. Zaballero Group 10‚ 2D Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is the most common technique‚ it is a process wherein the liquid is separated from the solution by boiling the liquid solution and condensing the vapor in order to get the distillate. There are four kind of distillation: simple distillation

Types of wastes : 1. Municipal Solid Waste Municipal solid waste (MSW) is generated from households‚ offices‚ hotels‚ shops‚ schools and other institutions. The major components are food waste‚ paper‚ plastic‚ rags‚ metal and glass‚ although demolition and construction debris is often included in collected waste‚ as are small quantities of hazardous waste‚ such as electric light bulbs‚ batteries‚ automotive parts and discarded medicines and chemicals. Generation rates for MSW vary from city

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

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 country will lead to developingof biomethanation processes for the use of substrates other than cattle dung. At present‚most of them are treated as waste‚ garbage‚ nuisance and hazard. The improper or inadequate disposal of such wastes leads to unhealthy conditions. This becomes a sourceof pollution and a public health problem. If such waste is recycled in a biogas plant‚ itwill be a source of energy‚ health and wealth. 2)Alternative substrates for biomethanation When alternative substrates

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
