可可豆荚壳（CPH）代表巧克力制造过程中未充分利用的组分。虽然行业目前的重点是可以理解的可可豆，但外壳约占果实的75重量%。以前的研究一直占主导地位的碳水化合物聚合物存在于CPH，但这项工作突出了生物质中的生物聚合物木质素的存在。开发了优化的有机溶剂木质素分离方案，提供了显著的实际改进。这种新的协议也可能被证明是有用的农业废物衍生的生物质一般。高品质木质素的NMR分析导致改进的结构理解，提供的证据支持在优化的预处理期间发生的木质素的脱乙酰化。化学转化，使用甲苯磺酰化，叠氮化，铜催化点击协议，提供了一个修饰的木质素低聚物与有机磷基序连接。热重分析用于证明低聚物作为阻燃剂的潜力。还对从CPH分离的其它产物流进行了初步分析。从巧克力生产过程中产生的可可豆荚壳废料中提取木质素，对其进行分离、表征和改性，以生产新型阻燃材料。
Cocoa pod husks (CPHs) represent an underutilized component of the chocolate manufacturing process. While industry’s current focus is understandably on the cocoa beans, the husks make up around 75 wt % of the fruit. Previous studies have been dominated by the carbohydrate polymers present in CPHs, but this work highlights the presence of the biopolymer lignin in this biomass. An optimized organosolv lignin isolation protocol was developed, delivering significant practical improvements. This new protocol may also prove to be useful for agricultural waste-derived biomasses in general. NMR analysis of the high quality lignin led to an improved structural understanding, with evidence provided to support deacetylation of the lignin occurring during the optimized pretreatment. Chemical transformation, using a tosylation, azidation, copper-catalyzed click protocol, delivered a modified lignin oligomer with an organophosphorus motif attached. Thermogravimetric analysis was used to demonstrate the oligomer’s potential as a flame-retardant. Preliminary analysis of the other product streams isolated from the CPHs was also carried out. Lignin derived from cocoa pod husk waste from chocolate production was isolated, characterized, and modified to produce novel flame-retardant materials.
