  Glycerol-derived ester oligomers from cork suberin

  摘要：

  The cork suberin polyester was partially depolymerized by a methanolysis reaction catalyzed by calcium hydroxide. The methano-lisate was analysed by ESI-MS/MS in the form of [M + Li](+) adduct-ions. This reaction solubilized a mixture of monomers and oligomers, including a set of glycerol-derived dimeric and trimeric esters. Four types of glycerol esters were identified: monoacyl-glycerols of alpha,omega-diacids, of omega-hydroxyacids and of monoacids; diglycerol diesters of alpha,omega-diacids; diacylglycerols of alpha,omega-diacids; monoacylglycerols of linear dimeric esters of alpha,omega-diacids and omega-hydroxyacids. The alpha,omega-diacids and omega-hydroxyacids found as monomer residues in the glycerol esters are the main ones found as cork suberin monomers. It is concluded that suberin is a glycerol-derived lipid of polymeric dimensions. Due to the protective and insulating role that it plays in plants, suberin should be considered together with the other known glycerolipids that build up biological membranes.

• Oxetane-terminated telechelic epoxy-functional polyesters as cationically polymerizable thermoset resins: Tuning the reactivity with structural design
  作者：Susana Torron、Mats Johansson

  DOI：10.1002/pola.27673

  日期：2015.10.1

  A series of epoxy‐functional telechelic oligomers containing oxetane end groups have been synthesized. The precursor monomer, extracted from outer Birch bark, was first polymerized through enzyme‐catalyzed esterification to form oligomers having epoxy and/or oxetane groups in the structures. The oligoesters were subsequently crosslinked through cationic polymerization either by epoxy or oxetane homopolymerization

  合成了一系列含氧杂环丁烷基端基的环氧官能远螯低聚物。从白桦树皮外层提取的前体单体首先通过酶催化的酯化反应聚合，形成结构中具有环氧基和/或氧杂环丁烷的低聚物。当存在两种官能度时，随后通过环氧聚合或氧杂环丁烷均聚或共聚通过阳离子聚合使低聚酯交联。“原位”进行了树脂聚合的研究”使用实时傅里叶变换红外光谱法显示，与均聚相比，共聚是一种较好的选择。通过定制不同的结构，可以控制网络的最终机械性能。©2015 Wiley Periodicals，Inc. J. Polym。科学，A部分：Polym。化学 2015年，53，2258年至2266年

  Described herein are formulations and methods of reducing spoilage in harvested produce by reducing the rate of water or mass loss, thereby resulting in high quality produce with lower rates of spoilage. The present disclosure provides coatings and methods of coating produce to prevent moisture loss from produce during storage and shipment of the produce. This in turn allows the produce to be shipped and stored at lower relative humidity (e.g., lower than industry standards for shipment and storage, or lower than about 90% relative humidity), which can help delay the growth of biotic stressors such as fungi, bacteria, viruses, and/or pests.

  本文描述了一种减少收获农产品变质的配方和方法，通过减少水分或质量的流失速率，从而获得质量高、变质率低的农产品。本文提供了覆盖物和覆盖农产品的方法，以防止农产品在储存和运输过程中失去水分。这反过来允许农产品在较低的相对湿度下运输和储存（例如低于行业运输和储存标准或低于约90%的相对湿度），这可以延迟生物胁迫因素（如真菌、细菌、病毒和/或害虫）的生长。

  The invention relates to methods and apparatus, designed for the chemical processing of outer birch bark for obtaining triterpene compounds - betulin and lupeol as well as suberinic acids, used in the chemical and pharmaceutical, food and cosmetic industries. The technical task to be solved with this invention is to develop a simple and efficient method for the chemical processing of outer birch bark for obtaining betulin, lupeol and suberinic acid salts in one apparatus and one outer birch bark processing cycle. According to the present invention, the advanced technical task is attained by a method for chemical processing of outer birch bark, wherein the betulin from the previously ground outer birch bark is isolated with organic solvents in a closed extraction technological complex with the solvent's recovery and the return of the condensate in the recycle, the extract flow is passed through a crystalliser, and then the extract is passed to an evaporator, a heater and a condenser, and the condensed Solution is introduced to the extractor again. In the crystalliser, the crystalline betulin is settled, but lupeol is isolated by crystallisation from the precipitate in the evaporator. After accomplishing the extraction process, the outer birch bark in the extractor is depolymerised, using KOH. The proposed method and apparatus enabled realising the complex obtaining of betulin and lupeol, as well as suberin derivatives in the continuous process with the solvent recycle, wherein the yield of betulin and lupeol is enhanced, in comparison with the known methods. Besides, this method made it possible to shorten many times the extraction time, simultaneously enhancing the efficiency
