Propriétés physiques et chimiquesBTDA 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
UtilisationBenzophenone-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.

2421-28-5 – Uses and synthesis methods

PrésentationBenzophenone-3, 3 ‘,4,4’-tetracarboxylic dianhydride (BTDA) is used as an intermediate and polycondensation (fiber and powder production) in the industrial field to make plastic products or fine chemicals. Since BTDA is only manufactured and handled under closed conditions in an industrial environment, the consumer risk is minimal. The environmental impact, ecotoxicology and toxicology information available to BTDA is provided based on research and/or reliable assessment of its hazard characteristics.
physical and chemical propertiesBTDA is a brown 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.
applicationBTDA is used in the industrial sector as an intermediate in the manufacture of plastic products or fine chemicals.
health hazardsBTDA has no acute toxicity through oral and inhalation routes or skin contact. The substance irritates the eyes and respiratory tract. BTDA is sensitive to skin. BTDA is not mutagenic. BTDA is used as an intermediate and polycondensed with BTDA (fiber and powder production) to manufacture plastic products or fine chemicals in the industrial field. The use of BTDA includes the use in closed systems and mixing and mixing in batch processes, as well as the transfer or transfer of substances from containers or large and small containers to containers or large containers.
utilisationPolymerized monomer, used to synthesize polymeric monomer of high temperature resistant polymer materials.
