Physicochemical Properties This product is a colorless or pale yellow, transparent oily liquid with a slight ammonia odor. It exhibits strong alkaline properties and easily changes color upon exposure to light. It is hygroscopic. It dissolves readily in water and also in organic solvents such as ethanol, toluene, acetone, and ethyl acetate, but is poorly soluble in petroleum ether. Its boiling point is 261°C (101.3 kPa), and its relative density at 20°C is 1.04. This product is a strong organic base (with a pH value of 12.5–13.0) that is highly corrosive. It can react with carbon dioxide in the air and undergo chemical reactions with acidic substances to form salts. It will burn when exposed to open flames, releasing toxic gases.

Quality standards ：

Packaging specifications 200 kg per drum, packaged in galvanized iron drums; packaging can also be customized according to customer requirements.

Use It is an excellent organic base deacidifier in organic synthesis and is widely used in organic synthesis, the synthesis of semi-synthetic antibiotics, and other related fields. In the polyurethane industry, it serves as a catalyst and is extensively applied in the rubber and tire industries. It is also an outstanding medium-temperature curing agent for epoxy resins, as well as an excellent rust inhibitor and high-grade corrosion inhibitor. Furthermore, it finds applications in leveling dyeing of nylon, wool, and other protein-based materials.

Storage conditions Store in a cool, ventilated, and dry warehouse.
