THE PROBLEM This study aims to extract antioxidants from orange peels to use as natural preservatives especially for mangoes. Specifically‚ this study attempted to answer the following question: 1. How could the extracted antioxidant help the mango preserve its freshness? 2. Can the orange peels really be use as a alternative preservative for the mango? RESEARCH HYPOTHESIS Ha: The extracted preservative from the orange peel has no effect on the mango. Ho: The

NITRATION OF METHYL BENZOATE Purpose: The main objective of this experiment was to synthesize methyl nitrobenzoate from methyl benzoate‚ using the mixture of nitric and sulfuric acid by performing the process of electrophillic aromatic substitution. During this reaction‚ the combination of HNO3 and H2SO4 made a nitrating solution. The crystallization was done to accomplish pure product. The melting point and Thin Layer Chromatography (TLC) were performed to test the purity of the product. Using

Introduction The purpose of this experiment is to synthesize methyl nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. Reaction Procedures/ Observations Use a 50 ml beaker to cool about 6 ml of concentrated sulfuric acid in an ice water bath. Weigh the vial containing about 3 grams of methyl benzoate and add it to the cooled sulfuric acid. Next pour about 2 ml of sulfuric acid to the nitric acid in the vial
