DPT to Transfer 1,4-Butanediol Technology to Blue Star and Sanwei Company

The Davy Process Technology （DPT） Company in January 2007 had transferred the technology for production of 1,4- butandiol to two Chinese companies. The first one is the Blue Star Chemical ＆ New Material Stock Co., Ltd., which will construct a 55 kt/a 1,4-butandiol unit in Nanjing, using maleic anhydride as the starting material to manufacture 1,4- butandiol and tetrahydrofuran by means of the ester hydrogenation technique licensed by DPT. The feedstock needed by this project will be provided by local producer and this unit is scheduled to come on stream by the fourth quarter of 2008. The second licensee is the Shanxi Sanwei Group, which will construct a 70 kt/a 1,4-butandiol unit in Hongtong county using the similar technology to manufacture 1,4-butandiol and g-butyrolactone. The starting material-maleic anhydride-will be sourced from the nearby producer, and construction of this project is slated to be completed by the fourth quarter of 2007.
