Gasification Characteristics and Application Scope of CS Powder

CS was first synthesized by two Americans, Ben Cosen and Roger Stoughton, at Mingde University in 1928. The name CS is derived from the initials of these two surnames. In the 1950s and 1960s, CS fans became the subject of secret weapon research and development experiments in Porton Down, Wiltshire, England. The experiment was first carried out on animals, and then transferred to British Army personnel for testing. The effect of CS gas on animals is poor, which is related to the "degeneration of lacrimal glands and fur covering" of animals.

CS powder is a kind of riot control tear gas. The CS powder reaction is catalyzed by a weak base such as piperidine or pyridine. The synthesis method of the two has been used to this day. Newer and more efficient catalysis methods, the use of other bases, no solvents, microwave stimulation, etc. Ben Corson and Roger Stoughton described the physiological properties of this substance as: There are some dinitriles here that stimulate sneezing and tear. Tear gas powder is harmless when wet, but it is a disaster if it dries.

1. The gasification characteristics of CS powder

The thermal dispersion method of CS gas powder can cause toxic smoke, and the explosive method or duster can also be used to create fine powder, which can poison the ground and air. It can irritate the eyes, respiratory tract and skin, has a strong sneezing and tearing effect.

2. The scope of use of CS powder

In Western countries, the stimulant CS powder has not only become a powerful weapon for the military and police to suppress riots and maintain public order, but it has also become an item for civilians to use for self-defense. Like pepper spray, CS spray is one of the standard police equipment used by law enforcement officers in some countries. The CS powder is not only loaded into hand grenades, bullets and hand sprayers, but also loaded into the vehicle-mounted chemical sprayer for mobile riot suppression tasks. The CS powder is also put into containers of various shapes, such as sprayers for perfume bottles, for women and other users to use in self-defense.
