I posted procedures to prepare TCT (cyanuric chloride, trichloro-s-triazine) by two methods:
1. From cyanogen chloride trimerization. Very hazardous procedure!
2. By chlorination of methyl thiocyanate. The product of the chlorination is a mixture from which TCT precipitates. The TCT is filtered off and
purified. The filtrate is obnoxious and toxic, containing trichloromethyl sulfenyl chloride, thiophosgene, etc. Exhaustive chlorination of the mixture
ends with carbon tetrachloride.
The second route is much safer than the first, but still needs doing in a hood.
Methyl thiocyanate can be purchased or prepared, its preparation starts with carbon disulfide. This has also been covered in my previous posts, q.v.
I am very curoious as to pdb's "commercial grade" of cyanuric chloride. What brand, what packaging, and where did you get it?
I have Merck and Acros reagent grades. Commercial grades such as made by Italy's Lonza, usually come only in 20 Kg fiber drums.
It is best to be very specific because there has been a great deal of confusion on this forum between CC (TCT) and TCCA which is a common swimming
pool chlorinator. Related but not interchangeable. |
