Preparing Esters by esterification method using carboxylic acid to an alcohol‚ which is 1.0 ml of ethanoic acid to the ethanol‚ and ethanoic acid to the propan-1-ol‚ also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound‚ famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester‚ which was known of its smell. However it was expected to have a pleasant smell

make polymers. In most cases‚ esters are used for scents – they often smell fruity and sweet. In general‚ an esterification reaction results from a condensation reaction between a carboxylic acid and an alcohol. The carboxylic acid group loses an OH group‚ and the alcohol loses and H. For instance‚ the reaction between methanoic acid and methanol is shown below COOH+CH_3 OH →CHOOCH_3+H_2 O Purpose The purpose of this investigation is to verify the smell of esters Method Place 250 mL of deionized

yuiopasdfghjklzxcvbnmqwertyuiopas Arun Kumar Arun Kumar 002329-179 Abstract Esters are important industrial compounds. Different esters have different demands in the current industry. The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on

it must be distilled off as it is formed. To get the acid‚ heat under reflux. • Secondary alcohols are oxidised to ketones by acidified K2Cr2O7. Colour change is orange to green. • The C=O bond in aldehydes‚ ketones‚ carboxylic acids and esters can be identified by infrared spectroscopy. It produces a large peak around 1700 cm-1. 3. Reduction of Aldehydes and Ketones Reduction‚ here‚ means addition of hydrogen. a) Reduction using NaBH4 A specific reducing

The Preparation of Methyl Salicylate Introduction: Esters have various smells that differ due to the types of carboxylic acids and alcohols one mixes together. This is called esterfication. The reaction is catalyzed by an inorganic acid usually H2SO4 Purpose: In this lab Methanol alcohol and Salicylic acid were reacted together to form Methyl Salicylate. This was done to determine the characteristic odour of the Methyl Salicylate. Safety: Safety goggles must be worn at all times. Methanol: Toxic

Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters are named in almost a reverse fashion
