Fatty acid composition of oil extracted from raw white sesame seeds and their changes during different heat treatments: Fatty acid composition of the oil extracted from raw white sesame seeds (RWS) is shown in Table (4): The most abundantly found fatty acids were 18:2 (linoleic acid) being 45.68%‚ followed by 18:1 (oleic acid) 35.83%. Other fatty acids were found in considerable amount are 16:0 (Palmitic acid) 9.15% and 18:0 (stearic acid) 6.90% for RWS. The results obtained are in agreement

RUNNING HEAD: Synthesis of Banana Oil Abstract A reflux apparatus was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol‚ glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This

Preparation of Synthetic Banana Oil Eric Nelson Chem. 253-1: Deepali Rathore Lab 1: Preparation of Synthetic Banana Oil 9-24-10 Purpose To create Isopentyl acetate with no more than 10% isopentyl alcohol and no more than 2% acidic acid in its composition. Theory Esters are a chemical functional group that usually forms by loosing a hydroxyl group and having it replaced with an alkoxy group with the loss of hydrogen. Esters are most commonly produced by taking a carboxylic acid‚ and

September 30‚ 2012 Experiment 5‚ Preparation of Synthetic Banana Oil Introduction: This experiment prepares synthetic banana oil (isopentyl acetate) through the Fisher esterification method by combining isopentyl alcohol with acetic and sulfuric acid then heating the mixture under reflux for an hour. Esterification is a chemical reaction in which two reactants (an alcohol and an acid) form an ester as the reaction product. Observations and Data: When the sulfuric acid was combined

The Philippine banana industry is one of the top agricultural export earners. The increase in demand worldwide has resulted to greater expansion of area planted to banana. As a tropical country‚ Philippines grows an abundant varirety of fruit crops primarily for local consumption and export market. Banana is considered as the most important fruit crop in the country in terms of volume production and export earnings. Philippines ranks second to Ecuador as the top banana-exporting country in the world
