technology will "enhance the commercial profitability of integrated biorefineries by enabling co-production of high-volume fuels and the higher-margin commodity chemical, BDO." In its normal industrial synthesis , acetylene can be reacted with two equivalents of formaldehyde to form 1,4-butynediol. Using a proprietary, multi-step process, LyondellBasell manufactures 1,4-butanediol without using acetylene. The
