Mechanism for producing styrene?

Question

Can someone please help me (or link me to) the mechanism to produce styrene?

I don't need just the equations, I need the mechanism. I will award best answer.

Answer 1

Reaction 1 : Benzene + Ethylene + ( Acid Catalyst )---- > Ethylbenzene  

http://books.google.com/books?id=8QzH-BT...

( Example of Link for Reaction Mechanism ) You can find such links by using Key Words like " Acid Catalysed Production of Ethylbenzene from Benzene and Ethylene " and search in google.com

H2C=CH2 + (H+) ---- > (CH3-CH2+)

(CH3-CH2+) + C6H5-H ---- > C6H5(H)-CH2+-CH3

C6H5(H)-CH2+-CH3 ----( 1,2 Hydride Shift )-- > C6H5-CH2-CH3    

In practical, Catalyst is Metal halide ( Lewis Acid ; Electron Pair Acceptor ).

If you never study Organic Chemistry, it will be difficult to understand the mechanism.

Reaction 2 : Ethylbenzene ----( Dehydrogenation ; Using Catalyst )---- > Styrene

(

Mechanism for Dehydrogenation of Ethylbenzene is not shown.

Answer 2

Invention of polystyrene andd styrofoam is at the first link below

Styrene polymer is produced from styrene monomer see second  link bellow for making the monomer

The conventional method for producing styrene monomer is the alkylation of benzene with ethylene followed by dehydrogenation to produce styrene monomer.
