Butanediol BDO THF GBL DMS process, Hydrogenolysis and Esterification technology

Johnson Matthey is the leading technology provider for butanediol plants worldwide. The DAVY™ butanediol process can produce in a single reaction train, varying ratios of three products; 1,4 butanediol (BDO), tetrahydrofuran (THF), Di-methyl succinate (DMS) and gamma butyrolactone (GBL). Hydrogenolysis is a reaction where hydrogen is added to a compound and breaks that compound’s bonds, forming two molecules as a result. Johnson Matthey's DAVY™ hydrogenolysis technology reacts hydrogen gas (H2) with a vapour-phase carbonyl compound. Esters are organic compounds characterized by the RCOOR’ functional group, and are most commonly derived from the reaction of carboxylic acids with alcohols.
