| Fiziksel ve Kimyasal Özellikler | BTDA is a tan crystalline powder. The substance has a melting point of 218.67°C and decomposes at 360°C. The autoignition temperature is very high and no flammability is observed. The density of the substance is 1.5452 g/ml and the vapor pressure is 6.53E-011 Pa. The substance is slightly soluble in water, log Pow is 3.3 |
| Kullanım | Benzophenone-3, 3 ‘,4,4’-tetracarboxylic dianhydride (BTDA) is used in the industrial field as an intermediate and in polycondensation (fiber and powder production) for the manufacture of plastic products or fine chemicals. Since BTDA is only manufactured and handled in the closed conditions of an industrial environment, the consumer risk is minimal. The environmental impact, Ecotoxicology and toxicology information available for BTDA is provided based on research and/or a reliable assessment of its hazard profile. |
