HAZARDOUS
Examples of Handling Hazardous Substances
We will utilize raw materials whose environmental impact is never small while setting up factories in the city, control them as we wish, and connect organic synthesis to sustainable development goals. Thionyl chloride and cyanuric chloride used in chlorination are toxic to the human body, and carbon disulfide is highly flammable and toxic, so its use is generally avoided. The ability to use these chemicals, which other chemical manufacturers are reluctant to use, is the root of our manufacturing strength. Showa Kako has facilities capable of manufacturing the following hazardous substances as raw materials.
| Reaction type | structure |
|---|---|
| with cyanuric chloride. Synthesis of Triazine Derivatives |
 |
| with carbon disulfide. cyclization |
 |
| Thionyl chloride was used. chlorination |
 |
| with dimethyl sulfuric acid. N-methylation reaction (amine quaternization) |
 |
Chlorination reaction tank
Exhaust gas treatment facilities
In order to safely use the following chemicals as raw materials, our scrubbers (waste gas treatment equipment) are indispensable equipment, and we make every effort to inspect them.
| name | Designation of Laws and Regulations | CAS number |
|---|---|---|
| carbon disulfide | hazardous substance | 75-15-0 |
| thionyl chloride | hazardous substance | 7719-09-7 |
| chlorosulfonic acid | hazardous substance | 7790-94-5 |
| dimethyl sulfate | hazardous substance | 77-78-1 |
| hitorazine | poison | 302-01-2 |
| cyanuric chloride | not applicable | 108-77-0 |
