DAVY butanediol and co‐products process

Johnson Matthey are the provider of the leading DAVY^TM technology for butanediol (BDO) plants worldwide. We offer a more economical process by using low-cost raw materials, producing BDO from butane via maleic anhydride (MAH), or from sugar via succinic acid (SAC), with the latter process making bio-based BDO possible.

The DAVY process is also designed with an esterification step prior to hydrogenolysis. This achieves greater efficiency, and a higher-quality product.

In addition, our process can make BDO’s derivatives, tetrahydrofuran (THF) and y-butyrolactone (GBL), in variable ratios which are adjustable according to market need.

This flexible product output enables our licensees to respond quickly to changing market conditions by manufacturing the right product at the right time for the polymers and solvents industries.
