Chlorination of benzene
I tarted chlorination with benzene in the presence of uv light but after some time the liquid becom dark purple
Why?
Plz help me

Can you give more details? Did you add anything in the reaction vessel other than benzene and chlorine? Did you remember to turn off the UV light?
Where did you get your benzene from and what's your chlorine source?
Additionally, here's a link to prepchem for a synthesis of this compound for extra help:

Edit: One more note, beware that this substance is a potent insecticide and can break down into phosgene in the long term. Do you have proper
resources for disposal and storage?

I prepared clorine frome electrolysis of NaCl
I dried it from passing through H2SO4 it took only 15 minute to turn the liquid purple
I obtained benzene from printing press
I think high temperature is the reason of burning the solid

Did you try to purify your benzene beforehand or ensure that it was relatively pure? Considering that it sounds like it came from ink for a printing
press, I'd expect it to have some impurities that could be responsible for the color change...
Perhaps a good indicator would be to measure the density of your benzene. Do have some benzene left to test its purity?
Here's a reference to benzene' density if you're able to measure it: https://www.reference.com/science/density-benzene-a8a7f319c8...
Edit: fixed grammar

Ok i will test the purity of ramaining benzene
Thanx for reply
