Preparation of methyl m-nitrobenzoate by nitration using methyl benzoate‚ nitric acid‚ and sulfuric acid Aileen Quintana TA: Sijie Tues/Thurs 11:50 42067 Introduction: The purpose of this lab was to explore the concepts of electrophilic aromatic substitution‚ specifically nitration by synthesizing methyl m-nitrobenzoate using methyl benzoate‚ nitric acid and sulfuric acid. This nitration is a type of electrophilic aromatic substitution. A

April 04‚ 2014 Fisher Esterification Introduction: Esters are one of the most common derivatives of carboxylic acids and are widely distributed in both nature and industry. A Fischer Esterification is the formation of an ester and water from alcohol and an acid. It is the simplest means of synthesizing an ester and requires the reaction of a carboxylic acid and an alcohol. The general reaction of Fischer esterification is‚ CH3CO2H + ROH ↔ CH3CO2R + H2O (reaction1) CH3COOH + ROH ↔

family‚ a group of compounds that possess antibacterial and antifungal properties. These agents are esters of para-hydroxybenzoic acid‚ which is why they are collectively called parabens. However‚ in contrast to its cousins‚ ethylparaben‚ butylparaben‚ and propylparaben‚ methylparaben receives its specific name owing to the fact that its chemical structure contains the methyl alkyl group. Methylparaben is found in several fruits‚ in particular blueberries‚ where it acts as an antimicrobial agent. Methylparaben

Process Intensification – B51GD Esterification and Polymerisation in PET production Process Overview Polyethylene terephthalate is a polymer with broad applications worldwide‚ and one of the most produced polymers manufactured globally each year. It main application is the bottling industry where approximately 14.7 Mt in 2009. PET resin is produced conventionally in a two - step process displayed in figure 1.9. The first stage is the esterification of Terephthalic acid (PTA) with Ethylene glycol (EG)

Esterification Lab Introduction Esterification is an important part of organic chemistry that has many practical applications. Esterification can be used to 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

Title: Esterification Objective: To synthesis acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification

Also known as "benzoate of soda‚" sodium benzoate is an FDA-approved‚ polyunsaturated fat that has been used by food manufacturers for over 80 years to inhibit microbial growth. As a food additive it is used as a preservative‚ effectively killing most yeasts‚ bacteria and fungi. Sodium benzoate is effective only in acidic conditions (pH < 3.6) making its use most prevalent in foods such as preserves‚ salad dressings (vinegar)‚ carbonated drinks (carbonic acid)‚ jams (citric acid)‚ fruit juices (citric
