When O-Xylene is used for production of phthalic anhydride is?

The selectivity for the phthalic anhydride reaction is 70%, for the complete combustion of o-xylene is 15%, for the incomplete combustion of o-xylene is 5%, for maleic anhydride is 9%, and for the heavy impurity is 1%.

Which reactor is recommended for an air oxidation of naphthalene to phthalic anhydride?

Example: Oxidation of Naphthalene to Phthalic Anhydride The oxidation is to be carried out in a packed bed reactor with cooling.

Which is the formula for phthalic anhydride?

C8H4O3
Phthalic anhydride/Formula

What is the formula of phthalic anhydride?

How do you convert phthalic acid to naphthalene?

Naphthalene on oxidation with potassium permanganate or potassium dichromate gives phthalic acid.

What happens when naphthalene reacts with KMnO4?

Benzoic acid. The formation of dicarboxylic acid occurs during the oxidation of naphthalene with KMnO4 in acidic condition.

Which compound is oxidised by KMnO4 in presence of acid in this reaction of course feso4?

Answer: (a) KMnO4 is an oxidising agent, it oxidises FeSO4 In this reaction, potassium permanganate (KMnO4) is an oxidizing agent. It oxidises ferrous sulphate to ferric sulphate in the presence of dilute H2SO4.

How to make phthalic anhydride from o-xylene?

Reactions path way In the reactor, the o-xylene is subject to a variety of oxidation reaction to the desired product of Phthalic anhydride; by product Maleic anhydride and products of combustion. The oxidation of o-xylene feed with the air produce Phthalic anhydride.

What are the reactions that occur beside the production of phthalic anhydride?

There are five reactions happen beside the production of phthalic anhydride by oxidation of o-xylene. These reactions are listed below. [6] + → + + . → + + . → + + . → + + + → + The first reaction is the main reaction and it is assumed 70% selectivity.

What happens when o-xylene reacts with oxygen?

Also, o-xylene reacts with the oxygen to produce the Maleic anhydride as by product that also react with excess oxygen to produce water and carbon dioxide. 3 f Figure 3: Reactions Pathway Type of reactors In the past, phthalic anhydride (PAN) was produced in a slurry.

What is the selectivity of the second reaction of xylene?

The second Reaction refers to the formation of the by-product maleic anhydride (MA) and a 10% selectivity is considered. The third and the fourth reactions represent the complete and incomplete combustions of o-xylene with 15% and 5% selectivity, respectively.
