Bioethanol Production from Allamanda cathartica

Abstract

INTRODUCTION

Ethanol, commonly known as ethyl alcohol is widely used not only in the Philippines, but also in other countries. It is an intoxicating agent in fermented and distilled liquors, it is used pure or denatured in solvents or medicines, it can also be found in colognes and cleaning agents and lastly it is proposed as a renewable clean-burning additive to gasoline. But store-bought ethanol are now expensive, so the researchers have thought of a way to lessen the burden that commercial ethanol bring by means of creating an alternative to ethanol that is cheaper and environment friendly. Yellow bell flowers are ornamental flowers that are abundant in the Philippines. It is used to treat a number of conditions including jaundice, malaria and constipation. With this uses the researchers sought for away to investigate other benefits of the yellow bell flower. Because of its high sugar content yellow bell flower was also used in the study.

METHODS

The researchers used three set ups: Set up A-fermented in two weeks , Set up B-fermented in three weeks, and Set up C-fermented in four weeks. The procedures involved were collecting, cleaning of yellow bell, extracting, boiling, application of yeast fermentation and distillation. The amount of yellow bell flowers, amount of yeast, and boiling point werekept constant, only the time of fermentation varies among the set ups. Certain factors were observed while the experiment was ongoing.

RESULTS

The researchers observed the effectiveness, odor, color, flammability, and physical appearance of the product.At the end of the experiment, results were analyzed statistically which proved that Set up B which was fermented in two weeks was the most effective in terms of odor, color, flammability and physical appearance among the other set ups. It had been, therefore, concluded by the researchers that the Set up B which was fermented in two weeks was the most effective among the other set ups.

DISCUSSIONS

After making this product, the researchers found out that they can make a cheap alternative to ethanol using yellow bell flowers. The results showed that bioethanol produced from yellow bell flowers is effective in terms of odor, color, physical appearance and flammability and its contents are pure biodegradable. it is also proved to be cheaper and more effective compared to commercial ones.
