Cracking Flashcards
(2 cards)
1
Q
What are the conditions for cracking
A
Long chain alkanes heated at 500 degrees
Zeolite catalyst
Products separated using fractional distillation
2
Q
Describe the method to crack long chain alkanes in the lab
A
LCA heated –> vaporise
Zeolite catalyst heated –> LCA pass over –> high temperature leads to cracking
Space above the catalyst so gases can pass freely over
Tube A collecing liquid products
Tube B collecting gaseous products
