Industrial Feedstock for Phthalate Ester Production
Ortho Phthalic Anhydride PA is an important organic chemical raw material with molecular formula C8H4O3 and CAS No. 85-44-9. It is supplied in industrial grade as white flake crystals or powder. Minimum purity is 99.7%, and the melting point is approximately 131°C. These specifications provide clear reference points for industrial receiving and subsequent synthesis.
Starting Material for DOP, DINP, DBP, and Resins
- PA occupies an upstream position in the phthalate plasticizer industry. It can be used to produce DOP, DINP, and DBP and also serves as a raw material for alkyd resins, unsaturated polyester, and other organic synthesis systems.
- Its function is different from a finished plasticizer used directly in flexible PVC. Plasticizer manufacturers purchase the material as a reaction feedstock for esterification, while resin producers can use it in alkyd resin and unsaturated polyester production. Purity and physical form provide practical criteria for industrial raw-material management.
Chemical-Chain Purchasing from One Supplier
Jiaxing Xiaolan Import and Export Co., Ltd. supplies Ortho Phthalic Anhydride PA together with downstream plasticizers including DOP, DINP, and DBP. The company works with manufacturing resources in the Yangtze River Delta and chemical-industry regions such as Shandong, Jiangsu, and Zhejiang.
Order, quality, and logistics personnel coordinate batch information, packaging, and shipment. This product range can serve plasticizer manufacturers, chemical raw-material distributors, and resin producers that require continuous purchasing of upstream chemical feedstocks.
Chemical-Chain Purchasing from One Supplier
- PA is packed in 25 kg woven bags or 500 kg large bags with moisture-protection measures. The 25 kg unit supports flexible material feeding and smaller production batches, while the 500 kg format is suited to bulk industrial consumption and more efficient handling.
- Specification customization is supported. COA and MSDS can accompany each batch, allowing incoming quality information and handling requirements to be reviewed together. The two packaging formats give esterification and resin plants practical options for aligning purchasing volume with warehouse and production requirements.
