Preperation Of Methyl Benzoate

Question 1

What are the reactants

Answer 1

The reactants are benzoate acid, methanol, and sulfuric acid

Question 2

What is the product

Answer 2

The product is methyl benzoate and water

Question 3

Methyl benzoate precaution

Answer 3

Combustible

Question 4

Benzoic acid precaution

Answer 4

Corrosive

Question 5

Diethyl ether precaution

Answer 5

Flammable

Question 6

What is the reaction time for this procedure

Answer 6

The reaction time is one hour

Question 7

What is the boiling point for after and why do you need to keep The hot plate at the lowest setting

Answer 7

The boiling point of ether is 34.6c

You need to keep the hot plate at the lowest setting because it’s very flammable

Question 8

You are preparing methyl benzoate which will be using the next lab how much will you need how much room for error do you have and making sure that you produce enough methyl benzoate

Answer 8

There should be twice as much as amount that is needed so there is room for error

Question 9

A four fold excess of methanol was used to push the reaction to completion why would you need to do this

Answer 9

The reaction is an equilibrium reaction so it would have slowed down significantly once enough methylbenzyl it was made to reach the equilibrium. The access methanol ensures an excess of reactants to push the reaction towards methyl benzoate

Question 10

Instep eight what compounds are contained in the aqueous layer

Answer 10

Unreacted sulfuric a is and most of unreacted methanol are contained in the aqueous layer

Question 11

Why did you add sodium bicarbonate and why did you need to vent frequently

Answer 11

Sodium bicarbonate was added to wash the product of any remaining assets it is necessary to vent frequently to remove any pressure buildup

Question 12

What was the purpose of using magnesium sulfate

Answer 12

The purpose of using it was to remove any water every made in the organic layer
