Diphenyl Carbonate DPC

Product Selling Points

Essential for sustainable polymer production: High purity diphenyl carbonate serves as the primary building block for non-phosgene synthesis of polycarbonate resins, enabling safer and more environmentally conscious manufacturing cycles.
Superior optical clarity for finished products: With iron levels strictly maintained below 3 ppm, our DPC ensures downstream plastics retain maximum transparency and resist thermal yellowing during processing.
Optimized for high molecular weight resins: Maintaining purity levels ≥99% and limiting phenol impurities to ≤0.8% provides consistent reactivity needed for high-performance engineering plastics.
Reliable industrial grade handling: The white flaky crystal form offers excellent flowability and low dust generation, improving worker safety and simplifying large-scale material transfer in refinery settings.

Product Introduction

Diphenyl Carbonate (DPC), identified by CAS 102-09-0, is a fundamental organic compound used extensively as an intermediate in the plastics and polymer industries. Appearing as white flaky crystals with the molecular formula C13H10O3, DPC is the preferred monomer for "green" synthesis of polycarbonates via the melt transesterification process. Unlike traditional methods, this route avoids highly toxic materials, making DPC a cornerstone of sustainable industrial chemistry. Its high melting point, combined with excellent solubility in organic solvents, also makes it valuable for synthesizing specialized plasticizers, solvents, and pharmaceutical precursors.
