Difenüülkarbonaadi

Difenüülkarbonaadi (DPD) is an organic compound with the chemical formula (C6H5O)2CO. It is a diester of carbonic acid and phenol. DPD appears as white crystalline solid at room temperature and is typically insoluble in water but soluble in many organic solvents.

The synthesis of difenüülkarbonaadi can be achieved through various methods. A common route involves the reaction of phenol with phosgene. Alternatively, it can be prepared by the transesterification of dimethyl carbonate or diethyl carbonate with phenol.

Difenüülkarbonaadi finds applications primarily as a chemical intermediate. It is used in the synthesis of polycarbonates, a class of polymers known for their strength, transparency, and heat resistance. These polymers are used in a wide range of products, including optical media (like CDs and DVDs), eyewear, electronic components, and automotive parts. DPD can also serve as a plasticizer and a component in certain specialty resins. Its reactivity allows for its incorporation into more complex molecular structures.
