Purity 99.8%: Phthalic Anhydride with 99.8% purity is used in alkyd resin production, where high purity ensures optimal polymerization and increases final coating durability. Melting Point 131°C: Phthalic Anhydride with a melting point of 131°C is used in plasticizer manufacturing, where the specific melting point facilitates efficient esterification and improves yield rates. Particle Size 20 micron: Phthalic Anhydride with 20 micron particle size is used in pigment synthesis, where uniform particle size allows for consistent dispersion and enhanced color stability. Stability Temperature 140°C: Phthalic Anhydride with stability up to 140°C is used in unsaturated polyester resin formulation, where high thermal stability enables controlled processing and superior mechanical strength in end products. Molecular Weight 148.1 g/mol: Phthalic Anhydride with a molecular weight of 148.1 g/mol is used in dye intermediate synthesis, where precise molecular specification ensures reproducible chemical reactions and consistent dye quality. |
| Packing | Phthalic Anhydride is packaged in a 25 kg net weight, tightly sealed, blue HDPE drum with clear hazard and handling labels. |
| Container Loading (20′ FCL) | 20′ FCL loads approximately 22 MT of Phthalic Anhydride, packed in 25 kg bags, stacked securely for safe transportation. |
| Shipping | Phthalic anhydride is transported in tightly sealed drums, bags, or bulk containers to prevent moisture ingress, as it is highly sensitive to water. It should be shipped in cool, dry, and well-ventilated conditions, away from incompatible substances like strong oxidizers. Proper labeling and compliance with hazardous material regulations are required. |
| Storage | Phthalic anhydride should be stored in a tightly closed, airtight container in a cool, dry, well-ventilated area away from moisture, heat sources, and incompatible substances such as strong oxidizers and bases. Containers should be clearly labeled and kept away from direct sunlight. Ensure proper containment to avoid dust generation and protect from physical damage or water sources to prevent hydrolysis. |
| Shelf Life | Phthalic anhydride typically has a shelf life of 2-3 years when stored in a cool, dry, well-sealed container. |
