Functionalized polymer building blocks for high performance bioplastics production using novel catalysts and recycled vegetable oils

低分子量结构单元最近在有机材料的自下而上制造方面引起了极大的兴趣。目前用于超分子化学的结构单元主要由不可再生的原料合成。然而，“绿色”化学合成对于产生新的生物基结构单元呈现出明显的优势，因为它们可从可再生资源获得。该提案的具体目标是：1）催化剂配制和表征; 2）用于模型官能化烯烃：油酸甲酯的复分解反应操作条件的优化; 3）催化剂稳定性及其抗失活性; 4）模拟典型植物油的模型甘油三酯的复分解; 5）用过的植物油（用过的高油酸向日葵）的复分解。在催化、材料化学、生物基聚合物反应工程等领域有很大的发展潜力。该项目将产生的好处是非常重要的加拿大油脂工业，加拿大农业企业整体以及加拿大塑料工业。这项研究不仅对回收植物油的附加值有直接影响，而且对满足“绿色化学”要求的催化工艺的开发，以及从可再生资源生产生物塑料工业的原料，同时减少塑料工业对来自不可再生资源的碳氢化合物的需求也有直接影响。因此，这项研究有助于生物塑料技术的发展，并使生物塑料部门和塑料行业受益。加拿大食品和食品服务部门有机会回收和加工使用过的植物油，使之成为有利润的增值产品，并提高加拿大油籽种植者和油脂加工者的利润和竞争力。

Low molecular weight building blocks have recently attracted enormous interest in terms of bottom-up fabrication of organic materials. The building blocks currently used in supramolecular chemistry are synthesized mainly from non renewable-based raw materials. However, the 'green' chemical synthesis presents distinct advantages for the generation of new bio-based building blocks since they are obtainable from renewable resources. The specific objectives of the proposal are: 1) Catalysts formulation and characterization; 2) Optimization of the metathesis reaction operating conditions for a model functionalized olefin: methyl oleate ester; 3) Catalyst stability and its resistance to deactivation; 4) Metathesis of a model triglyceride simulating typical vegetable oils; 5) Metathesis of a used vegetable oils (used high oleic sunflower). There is a high potential for developing new knowledge in the area of catalysis, materials chemistry, bio-based polymer reaction engineering. The benefits that would accrue from this project are highly significant to the Canadian fats and oils industry, the Canadian Agri-business overall as well as the Canadian plastics industry. This study has direct implications not only with respect to value-addition to recycled vegetable oils but also with respect to the development of catalytic process that meets the requirements of 'Green Chemistry', and the production of feed stocks to the bioplastics industry from renewable resources while reducing the demand from plastics industry for hydrocarbons from non-renewable resources. Thus this research could contribute to the development of bioplastics technologies and benefit the bioplastics sector and the plastics industry. There are opportunities for the Canadian Food and food service sectors to recycle and process used vegetable oils profitably to value-added products, and to improve the profitability and competitiveness for the Canadian oil seed growers and fats and oil processors.
