硫酸钴
Cobalt(II) sulphate | 233-334-2 | 10124-43-3 | CMR | It is used as a drying agent in ceramic glazes and paints, as well as in electroplating, alkaline batteries, the production of cobalt-containing pigments and other cobalt products, and in catalysts, analytical reagents, feed additives, tire adhesives, and lithopone additives. |
硝酸钴
Cobalt(II) dinitrate | 233-402-1 | 10141-05-6 | CMR | It is used as a pigment, catalyst, and in the ceramics industry. It is also used in surface treatment and batteries. |
碳酸钴
Cobalt(II) carbonate | 208-169-4 | 513-79-1 | CMR | It is mainly used in the manufacture of catalysts, and also in small quantities in the manufacture of feed additives, pigments and other chemicals, as well as as a base glaze adhesive. |
醋酸钴
Cobalt(II) diacetate | 200-755-8 | 71-48-7 | CMR | It is mainly used in catalyst manufacturing, and in smaller quantities in surface treatment, alloys, pigments, rubber adhesives and feed additives. |
乙二醇單甲醚
2-Methoxyethanol | 203-713-7 | 109-86-4 | CMR | It is mainly used as a solvent and chemical intermediate, as an additive in the fuel industry, and as a dyeing auxiliary in the textile industry. |
