percentage content of ethanol in 3 samples (spirit‚ wine and a beer). We would be comparing the concentration of ethanol to that of 25%propanol which would act as an internal standard. Method To set up the standards for a calibration curve we would make solutions of different concentrations of ethanol. Using a 25cm3 volumetric flask we would put 10cm3 of 25% Propanol into each one which would act as an internal standard. We would then add differing amounts of ethanol (0.5 cm3‚ 1.0cm3‚ 2.0cm3and

Rabang‚ Maika I. 2B-Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is a technique in separating two liquid components. There are two types of distillation used in this experiment known as the simple and fractional distillation. The objective of this experiment was to be able to determine the amount of Ethanol in the given

WASTE TREATMENT The treatment is dedicated to finding solutions to agricultural problems by developing alternatives that maintain levels of production while cultivating healthy foods‚ preserving the health of farmers‚ and not polluting surrounding ecosystems. The banana industry creates many by-products that result from the harvesting and processing of bananas. These by-products are banana peels‚ banana stems‚ and liquid wastes. Currently these wastes are dumped in landfills‚ rivers‚ oceans and

BIO ETHANOL FUEL OUT OF FERMENTED BANANA (Musa balbasiana) PEELINGS Authors/ Researchers: Asprec‚ ‚ Centeno‚ Cruz‚ Jumadiao‚ Sanchez‚ Silaya‚ The Problem and Its Background Background of the study Bio-ethanol fuel has been used through these times and produced in many places specifically in Brazil and United States which contributes to the 87.1% bio-ethanol production in the world. Besides from being eco-friendly‚ inexpensive and less toxic‚ it is more preferred as a fuel for the materials

been enforced in recent years (Wyman‚ 1994). In this regard‚ India reforms are taken by blending 10 to 15% ethanol in its gasoline usages. Converting a renewable non-fossil carbon‚ such as organic wastes and biomass consisting of all growing organic matter (plants‚ grasses‚ fruit wastes and algae) to fuel would assure a continual energy supply (Wyman‚ 1996).

Bio-ethanol is manufactured from fermenting starch‚ wheat and sugar cane. Ethanol is also made from the hydration of ethylene from petroleum‚ though the majority of ethanol is produced by fermentation. It is considered an alternative fuel source as it is regarded to be renewable and more beneficial to the environment. As a car fuel ethanol is blended with petrol in different concentrations. In cars‚ carbon monoxide is produced from the incomplete combustion of petroleum. By adding ethanol which

So‚ the researcher came up of using the malunggay leaves extract as source of ethanol since based on the study done by Senator Loren Legarda‚ the extracts obtained from the leaves of malunggay plant is 80% ethanol‚ which is used for fuels. This study knew the possibility of ethanol from malunggay leaves extract. First‚ the researcher gathered the needed the raw material‚ the malunggay leaves. It weighted .75 kilogram. Then‚ through
