Riot control agents generation

METHODS FOR THE GENERATION AND DISPERSAL OF RIOT CONTROL AGENTS... 

Like CS, the riot control agent known as CN (1-chloroacetophenone) is a solid or powder and can be disseminated as a smoke generated from a grenade or other device, or in powder or liquid formulations. Under the trade name Mace, it is in most devices sold for self-protection, although today it is commonly mixed with or is being replaced by capsaicin (pepper spray). 

The riot control agent known as CR (dibenz(b,f)-1 4-oxazepine) is a relatively new compound, first synthesized in 1962 by Higginbottom and Suschitzkey. CR is more potent and less toxic than CS. Because of the low vapor pressure of CR solution, no respiratory tract effects are anticipated from its use. The LCt5g for animals exposed to grenade-generated smokes was found to be 167,500 mg min/m3. The estimated LCt50 for humans is probably higher than 100,000 mg min/m3.24...
