Question

Decaline can be prepared by​

Answer 1

Answer:

It is the saturated analog of naphthalene and can be prepared from it by hydrogenation in the presence of a catalyst. Decalin easily forms explosive organic peroxides upon storage in the presence of air.

Answer 2

Answer:

Decalin is mainly obtained by hydrogenation of naphthalene in the presence of a catalyst.

Explanation:

What is Decalin?    

Decalin is an organic compound consisting of two cyclohexane rings that are ortho-fused. It is a Decahydro- analogue of Naphthalene.

What are the properties of Decalin?

Decalin has the following properties:

• Its molecular formula is C₁₀H₁₈

• its average mass is 138.25

• it is a saturated hydrocarbon

• it is an excellent solvent and cleaning fluid
• When stored in the presence of air, decalin quickly generates explosive organic peroxides

How to prepare Decalin?

Preparation of Decalin includes hydrogenation of Naphthalene in the presence of a Ni and Ir catalyst. At first, on hydrogenation Naphthalene is converted to Tetralin which when hydrogenated further gets converted into the cis and trans form of Decalin.
