1,4‐Butanediol (1,4‐BDO) is a four‐carbon diol used for industrial applications such as organic solvents, and the production of adhesives, fibers and polyurethanes. 1,4‐BDO currently is produced through several petrochemical routes: hydrogenation of maleic anhydride, isomerization of propylene oxide, acetoxylation of butadiene, and the reaction between formaldehyde and acetylene. The current trends in 1,4‐BDO production involve the utilization of renewable sources such as biomass. In this context, the present study aimed to identify promising technologies of 1,4‐BDO production through prospecting methodology based on the analyses of patents and scientific article, describing the most relevant aspects of those emerging technologies. An increasing amount of 1,4‐BDO production focused on biotechnological routes has been reported, with the US heavily involved in the development of new technologies. This study tracked three promising technologies which have potential for application in a biorefinery context because those processes involve (i) production of 1,4‐BDO from sugars, classified herein as the biotechnological route; (ii) production of intermediates from sugar fermentation followed by catalytic conversion into 1,4‐BDO, classified herein as the hybrid route, and (iii) furan/furfural conversion into 1,4‐BDO. © 2020 Society of Chemical Industry

使用勘探方法确定潜在的1,4-丁二醇生产技术

1,4-丁二醇（1,4-BDO）是一种四碳二醇，用于工业应用，例如有机溶剂以及粘合剂，纤维和聚氨酯的生产。1,4-BDO目前是通过几种石化途径生产的：马来酸酐的氢化，环氧丙烷的异构化，丁二烯的乙酰氧基化以及甲醛和乙炔之间的反应。1,4-BDO生产的当前趋势涉及生物质等可再生资源的利用。在此背景下，本研究旨在通过对专利和科学文章的分析，通过探矿方法来确定1,4-BDO生产的有前途的技术，描述那些新兴技术的最相关方面。据报道，专注于生物技术路线的1,4-BDO生产量不断增加，美国大力参与了新技术的开发。这项研究跟踪了三项有前途的技术，它们有可能在生物炼制中应用，因为这些过程涉及（i）从糖中生产1,4-BDO，在本文中被归类为生物技术路线；（ii）通过糖发酵生产中间体，然后催化转化为1,4-BDO（在此归类为杂交途径），以及（iii）呋喃/糠醛转化为1,4-BDO。©2020化学工业协会 （ii）通过糖发酵生产中间体，然后催化转化为1,4-BDO（在此归类为杂交途径），以及（iii）呋喃/糠醛转化为1,4-BDO。©2020化学工业协会 （ii）通过糖发酵生产中间体，然后催化转化为1,4-BDO（在此归类为杂交途径），以及（iii）呋喃/糠醛转化为1,4-BDO。©2020化学工业协会
