LIGNOX is an entirely new approach to the production of high-volume aromatic compounds from Lignin, a widely available bio-waste material which is currently burned as a low grade source of heat. Our approach is based in a process developed at Nottingham for the selective partial oxidation of methylated aromatics in supercritical water, scH2O, catalysed by MnBr2. This scH2O process has been shown to have potentially major advantages over current methods for manufacturing aromatic carboxylic acids in acetic acid solvent. LIGNOX involves three partners (i) INVISTA, world-leading developer and licensor of process technology especially large-scale selective oxidation, (ii) the National Non-Food Crops Centre with expertise in exploitation of bio-feed stocks, and (iii) Nottingham which has unique expertise in supercritical fluids, especially scH2O. Nottingham's role is to carry out the fundamental chemical investigation underpinning the project. The tasks include (a) designing and optimizing the high pressure equipment, initially to be based on the patented Nozzle Reactor developed at Nottingham, (b) designing and carrying out an experimental programme to establish the best strategy for controlling separately the selective oxidation of C-C bonds and hydrolysis of ether side chains, thereby providing the tools for directing the breakdown of the polymeric products and (c) developing effective on-line and off-line analytical procedures for the rapid speciation and quantification of reaction products. A key component of our proposed programme is the use of FTIR spectroscopy with ATR sampling for on-line monitoring and more rapid reaction optimization, a novel approach based on promising preliminary results from the Nottingham team using loaned equipment. We seek funding for equipment, consumables and essential manpower to turn this project into reality. The importance of this project is that Lignin is one of the very few bio-feedstocks for aromatic compounds. Therefore, LIGNOX is a major step torwards manufacturing aromatic compounds from a suitable bio-feedstock, which is available in sufficient tonnage to be a viable source of bulk chemicals on a world-scale.

LIGNOX 是一种从木质素中生产大量芳香族化合物的全新方法，木质素是一种广泛使用的生物废料，目前作为低级热源进行燃烧。我们的方法基于诺丁汉开发的一种工艺，用于在 MnBr2 催化下，在超临界水 scH2O 中选择性部分氧化甲基化芳烃。与目前在乙酸溶剂中制造芳香族羧酸的方法相比，这种 scH2O 工艺已被证明具有潜在的主要优势。 LIGNOX 涉及三个合作伙伴 (i) 英威达 (INVISTA)，世界领先的工艺技术开发商和许可方，尤其是大规模选择性氧化技术，(ii) 拥有生物原料开发专业知识的国家非粮食作物中心，以及 (iii) 诺丁汉在超临界流体，特别是 scH2O 方面拥有独特的专业知识。诺丁汉的作用是进行支持该项目的基础化学研究。任务包括（a）设计和优化高压设备，最初基于诺丁汉开发的专利喷嘴反应器，（b）设计和实施实验程序，以建立单独控制C-C选择性氧化的最佳策略醚侧链的键和水解，从而提供指导聚合物产品分解的工具，以及（c）开发有效的在线和离线分析程序，用于反应产物的快速形态分析和定量。我们提出的计划的一个关键组成部分是使用 FTIR 光谱与 ATR 采样进行在线监测和更快速的反应优化，这是一种基于诺丁汉团队使用借来设备的有希望的初步结果的新颖方法。我们寻求设备、消耗品和必要人力的资金，以使该项目成为现实。该项目的重要性在于木质素是为数不多的芳香族化合物生物原料之一。因此，LIGNOX 是利用合适的生物原料制造芳香族化合物的重要一步，该生物原料的吨位足以成为世界范围内大宗化学品的可行来源。
