  协调促进生物儿茶酚电重整以实现可持续聚合物生产

  摘要：

  可持续的聚合物生产对于碳中和社会至关重要。顺式、顺式粘康酸作为一种生物质衍生平台分子，可直接接触己二酸和对苯二甲酸（商业聚合物的主要单体），吸引了越来越多的兴趣。在此，提出了一种将生物可再生邻苯二酚电重整为顺式、顺式粘康酸并同时生产H 2的可持续路线。通过使用CuO泡沫电极，在没有外部氧化剂的环境条件下可以实现90%的高顺式、顺式粘康酸产率和87%的高法拉第效率。Zn 2+与儿茶酚的配位对于产率和选择性至关重要。通过稳态电化学动力学、原位光谱和理论计算的组合分析，我们揭示了儿茶酚电氧化的反应体系涉及聚合、开环和解聚三个主要过程，其中Zn 2+ 配位是非常有效的延迟聚合并促进顺式、顺式-粘康酸的环裂解。与Zn 2+阳离子配位的儿茶酚盐通过部分结构变形重新分配其电子密度，以加速电子转移并促进OH -亲核攻击。最终证明了实用的双电极系统能够高效稳定地将邻苯二酚电重整为可分离的顺式、顺式粘康酸和氢

  The invention pertains to a process for producing a glycerol tri-carboxylic acid polyester foam which comprises the steps of combining glycerol and a tri-carboxylic acid in the liquid phase to provide a reaction mixture, and keeping the reaction mixture at a temperature of between 80° C. and 130+ C. from the start of the reaction until a conversion of at least 90% is obtained. The foamed polyester of the present invention is “green”, biodegradable, and non-toxic, and can be cleanly combusted. It finds application in, int. al., packaging materials, insulation materials, and materials with a short life cycle.

  This invention relates to bio-based polyfunctional carboxylic acids reacted with vinyl ether compounds to form liquid vinyl-blocked bio-based polyfunctional carboxylic acids. These liquid vinyl-blocked bio-based polyfunctional carboxylic acids can be mixed with a polyfunctional vegetable oil-based epoxy resin to form a homogeneous curable coating composition. Upon curing at elevated temperature, thermoset coatings are formed which have excellent hardness, solvent resistance, adhesion, and flexibility. The invention also relates to the use of a curable coating composition comprising at least one polyfunctional vegetable oil-based epoxy resin and at least one vinyl-blocked bio-based polyfunctional carboxylic acid, which may be coated onto a substrate and cured thermally. Methods of making the vinyl-blocked bio-based polyfunctional carboxylic acids and curable coating compositions and substrates containing the same are also disclosed.

  The present invention provides DNA molecules that constitute fragments of the genome of a plant, and polypeptides encoded thereby. The DNA molecules are useful for specifying a gene product in cells, either as a promoter or as a protein coding sequence or as an UTR or as a 3' termination sequence, and are also useful in controlling the behavior of a gene in the chromosome, in controlling the expression of a gene or as tools for genetic mapping, recognizing or isolating identical or related DNA fragments, or identification of a particular individual organism, or for clustering of a group of organisms with a common trait. 0Arabidopsis DNA is used in the present experiment, but the procedure is a general one.

  本发明提供了构成植物基因组片段的 DNA 分子及其编码的多肽。这些 DNA 分子可作为启动子或蛋白质编码序列或 UTR 或 3'终止序列，用于指定细胞中的基因产物，也可用于控制染色体中基因的行为，控制基因的表达，或作为基因绘图、识别或分离相同或相关 DNA 片段、或识别特定生物个体、或对具有共同性状的生物群体进行聚类的工具。 本实验中使用的是拟南芥 DNA，但这是一个通用程序。
