Dibutyl carbonate

Dibutyl carbonate (CAS 542-52-9), also known as n-butyl carbonate, is a carbonate ester solvent used across polymer processing and industrial lubrication. It functions as both a solvent and a plasticizer, offering low volatility and good compatibility with a range of resin systems.

In plastics and polymer manufacturing, this compound acts as a plasticizer to improve flexibility and processability in resin formulations, particularly for coatings and films. It serves as a reactive solvent and intermediate in polycarbonate synthesis.

Carbonate exchange reactions are central to production in these applications. In lubricant formulations, its ester structure contributes to base fluid blending and additive carrier applications where controlled viscosity and thermal stability are required.

It is also evaluated as a green solvent alternative in specialty coatings, reducing reliance on more regulated solvent systems. This versatility makes it a valuable component in modern chemical manufacturing and industrial formulation processes.

The product is supplied as a clear liquid in standard industrial packaging, including drums and IBC containers. Technical grade is the primary commercial specification available from most suppliers for large-scale industrial use.

Purity levels of 99% and above are standard for polymer and solvent-grade applications. This high level of purity ensures consistent performance in sensitive chemical reactions and high-performance coating systems across various sectors.
