日本旭化成公司正在开发一种丙烯制丙烯腈生产新工艺。据称,该专有工艺将使其产品收率达到80%以上,大大超过传统工艺的70%的水平。旭化成表示,将继续进一步试验,并力争在工业装置上应用。该公司的最终目标是使聚丙烯等在内的丙烯衍生物产品达到全球最高的产品收率水平。如果该 Asahi Kasei Corporation is developing a new process for producing acrylonitrile from propylene. Allegedly, the proprietary process will enable its product yield to reach more than 80%, much higher than the traditional process of 70% level. Asahi Kasei said it will continue to test further and strive to apply in industrial installations. The company’s ultimate goal is to make propylene derivatives, including polypropylene, the world’s highest product yield. If that
