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

Abstract Isopentyl acetate was synthesized in 44.9% yield through a reaction between isopentyl alcohol and acetic acid‚ with sulfuric acid as a catalyst. Identify and purity of the product was confirmed by infrared spectrum analysis of the product and the boiling point (141-142˚C) to the published value of (lit1142.5 ˚C). Procedure: Isopentyl alcohol (.893g)‚ acetic acid (2ml)‚ and concentrated sulfuric acid (4 drops) was added to a 5ml conical vial‚ and then attached to a reflux apparatus.

BACKGROUND: Esterification is a reaction that combines an alcohol with an organic acid‚ with a water molecule is being taken out‚ and an ester is formed. A concentrated acid catalyst speeds up the esterification. In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ can

ALCOHOL Drinking alcohol is like taking a drug. It is a form of drug abuse‚ and drug addiction. This is a worldwide problem that many people are involved in. There are good effects of alcohol if it is in small amounts and in self-control. On the other hand there are bad effects‚ if you take for long time. The effects that a person will get are all based on certain factors like‚ how much and how often alcohol is consumed‚ the age of the person‚ when the person started and how long they have been

When the word alcohol is brought up‚ what do you think about? What comes to my mind is parties‚ and what people think they have to drink to have fun. Did you know that over 5‚000 people under the age of 21 die each year from alcohol-related car crashes‚ suicides‚ homicides‚ alcohol poisoning‚ and other injuries such as falls‚ burns‚ and drowning? Alcohol can be a very dangerous substance if not treated correctly and drank responsibly. Alcohol is a form of a drug but unlike the other drug‚ marijuana

Figure 1: Formation of benzocaine from p-aminobenzoic acid Experimental P-aminobenzoic acid (1.211g) and absolute ethanol (15mls) were combined with three boiling chips in a 50ml round bottom flask. The round bottom flask was placed on a heating plate and was refluxed starting at 109 ̊C. The solution began boiling at 111 ̊C. It was allowed to reflux for approximately 30 minutes and the solid was dissolved. The round bottom flask was then placed in an ice bath and allowed to cool to

________________________________________ Absorption Alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood. However the small intestine is by far the most efficient region of the gastrointestinal tract for alcohol absorption because of its very large surface area. In a fasting individual‚ it is generally agreed that 10% to 20% of a dose of alcohol is absorbed from the stomach (the volume of alcohol affects the absorption) and 75% to 80% is absorbed

chemistry‚ an alcohol is an organic compound in which the hydroxyl functional group (-OH) is bound to a carbon atom. In particular‚ this carbon center should be saturated‚ having single bonds to three other atoms.[1] An important class of alcohols are the simple acyclic alcohols‚ the general formula for which is CnH2n+1OH. Of those‚ ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages‚ and in common speech the word alcohol refers specifically to ethanol. Other alcohols are usually
