Ethanol is generally produced by the fermentation of sugar‚ cellulose or converted starch and has along history. In Nigeria‚ local production of ethanol from maze‚ guinea corn‚ millet‚ cassava and cellulose is as old as the country itself. Apart from food and pharmaceutical uses‚ ethanol is finding itself alternative uses for biofuel in most of the developed world for the reasons: it is not poisonous

Experiment #1 Preparation of Ethanol from Sucrose Based on R. Weglein & C.L> Yau‚ CHEM 203 Experiments in Organic Chemistry II Laboratory‚ 5th Edition‚ 2006‚ p29-32. Statement of Purpose: An aqueous solution of ethanol is prepared by the fermentation of sucrose. The percent alcohol is the resulting solution and the percent conversions of the sucrose are to be determined. Introduction: Sucrose is a molecule containing glucose and fructose. http://faculty.tcc.fl.edu/scma/phelpsj/experiments/ethanol

ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction

Why does the colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot‚ the more pigments well leak out from the cell membrane‚ hence the absorbance would increase. My hypothesis was concluded by the facts that beetroot contains red pigments called betalians which are located in the cell vacuole. Normally the pigments cannot leak out; however cooking the beetroot allows the movement. This is because the cell

source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil is the largest suppler and consumer of ethanol in the world. Ethanol functions

Why does colour leak out of cooked beetroot? Introduction When cooking a beetroot you are recommended not to remove the outer skin and not to cut off the entire stalk if you do not want the red dye in the cooking water. Beetroot contains a red pigment called betalain‚ which is in the cell vacuole. Normally the betalain stays inside the cell‚ however when the cell is exposed to extreme temperatures they leak out. The reason why they leak out is because of the cell membrane structure. When the

The aim of this thesis project is to study in vitro the permeability of amorphous drug systems in different conditions. First‚ three complementary techniques are performed to characterize the crystalline and amorphous form of indomethacin. These techniques include IR spectroscopy‚ Raman spectroscopy and differential scanning calorimetry. Indomethacin is a compound belonging to class II of the BCS and is consequently a poorly water-soluble drug. The limiting step in order to have a good bioavailability
