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“自然资源和能源”、“1.生物能源和生物产品”，重点是“从木质素中生产和分离酚类和碳”。生物质热解是一种有前景且已在工业上实施的方法。生产可用作运输燃料的液态碳氢化合物。然而，在“粗生物燃料”中，大约30 w/w %的有机成分是木质素，它是各种酚类芳族化合物的丰富来源，但目前被浪费（或燃烧以获取能源）。李的团队最近发现的“直接”苯酚催化胺化提供了一种新的“绿色化学”机会，通过将木质素苯酚转化为芳香胺来提高生物质利用的经济可行性。通过对粗热解生物质采用这种反应，我们期望实现两个目标：（1）通过 pH 控制萃取为所得胺提供低成本分离的方法；（2）创造高价值的电子功能材料（聚苯胺、三芳胺、咔唑）将用于下一代技术，包括聚合物电池、太阳能电池和固态照明。该项目的成功实现可能会对加拿大经济的化学和材料行业产生重大影响，从长远来看，有助于可持续能源解决方案。为了体现业界对我们的技术解决方案的广泛兴趣，三家加拿大公司已承诺支持该项目，并将与共同 PI 合作执行该项目。 Quandra Chemicals 对将苯酚转化为苯胺产品的绿色方法感兴趣； Advanced Materials Inc 生产苯胺和聚苯胺产品； 1-Materials 对基于木质素衍生的苯胺前体的电子材料感兴趣。该项目将为绿色化学、化学工程和材料发现方面的学士、硕士、博士和 PDF 级别的学生提供培训。
