This project is in direct response to the target area "Natural Resources and Energy", "1. Bioenergy and Bioproducts", focusing on "producing and separating phenolics and carbons from lignin".Biomass thermolysis is a promising and already industrially implemented approach for the production of liquid hydrocarbons that can be used as a transportation fuel. However, in the "crude biofuel", ca 30 w/w % of the organic component is lignin, which is a rich source of various phenolic aromatics, but is currently wasted (or burnt for energy). The recently discovered in Li's group *direct* catalytic amination of phenols provides a new "green chemistry" opportunity to enhance the economic feasibility of biomass utilization by converting the lignin phenols into aromatic amines. Adopting this reaction for the crude thermolyzed biomass, we expect to reach two goals: (1) provide a handle for low-cost separation of the resulting amines through pH-controlled extraction and (2) create high-value electronically functional materials (polyanilines, triarylamine, carbazoles) to be used in next generation technologies, including polymer batteries, solar cells and solid-state lighting.The successful realization of the project could have a major impact on chemical and materials sectors of Canadian economy, and in the long term, contribute to a sustainable energy solutions. As a reflection of this wide industrial interest in our technical solution, three Canadian companies have pledged their support to the project and will collaborate with co-PIs in executing the project. Quandra Chemicals is interested in green methods of conversion phenols into aniline products; Advanced Materials Inc in aniline and polyaniline products; and 1-Materials is interested electronic materials based on lignin-derived aniline precursors. The project will train students at BSc, MSc, PhD and PDF levels in green chemistry, chemical engineering and materials discovery.

该项目直接响应目标领域的“自然资源和能源”，“ 1。生物能源和生物产物”，重点是“生产和分离木质素的酚类和碳纤维”。BIOMASS热解是一种有希望的，并且已经实施了可以用作运输燃料的液体水水发产品的工业实现的方法。但是，在“粗糙生物燃料”中，有机成分的30 W/w％是木质素，它是各种酚类芳香剂的丰富来源，但目前被浪费（或为能量燃烧）。最近在李的组 *直接 *催化胺化的苯酚中发现了一个新的“绿色化学”机会，通过将木质素苯酚转化为芳香胺，从而增强生物量利用的经济可行性。 Adopting this reaction for the crude thermolyzed biomass, we expect to reach two goals: (1) provide a handle for low-cost separation of the resulting amines through pH-controlled extraction and (2) create high-value electronically functional materials (polyanilines, triarylamine, carbazoles) to be used in next generation technologies, including polymer batteries, solar cells and solid-state lighting.The successful realization of the project could have对加拿大经济的化学和材料部门的主要影响，从长远来看，有助于可持续的能源解决方案。为了反映我们的技术解决方案的这种广泛的工业兴趣，三家加拿大公司已承诺对该项目的支持，并将与Co-Pis合作执行该项目。 Quandra Chemicals对绿色转化酚的绿色方法感兴趣。 Aniline和聚苯胺产品中的高级材料Inc； 1材料是基于木质素衍生的苯胺前体的感兴趣的电子材料。该项目将在绿色化学，化学工程和材料发现中培训BSC，MSC，PhD和PDF水平的学生。
