拜耳材料科学公司(BMS)于2007年4月中旬推出最新的节能型TDI生产技术。尽管该法仍是气相光气化法,但该技术可在溶剂使用上节约80%,并可减少用能40%,尤其在蒸馏阶段节能显著。因为新技术投资费用也节减1/5,因此只需采用较小的装置就可生产这种发泡聚氨酯中间体。试验已在Dormage Bayer MaterialScience (BMS) in mid-April 2007 launched the latest energy-saving TDI production technology. Although this method is still the gas phosgenation method, but this technology can save 80% in the use of solvents, and can reduce energy consumption by 40%, especially in the distillation stage of energy-saving significant. Because new technology investment costs are also reduced by 1/5, so only need to use smaller devices to produce this foam polyurethane intermediates. The test is already in Dormage
