标题:环氧大豆油酸甲酯衍生溶剂的化学表征和物理性质
摘要:环氧大豆油酸甲酯(ems)与醇,二氧化碳和丙酮的反应产生的液体具有溶剂性质,使其比大豆油酸甲酯更适合溶解极性物质.Ems中的amberlyst-15与醇的存在下的反应,包括甲醇,乙醇,ñ丁醇和2-甲氧基乙醇产生了一系列含有醚(-or)和醇(-oh)基团的溶剂.Ems与二氧化碳和丙酮的反应分别得到具有碳酸酯和酮官能团的产物.通过ms和NMR研究表征了由ems与meoh反应产生的产物ems(meoh)中存在的化合物的复杂混合物.除了由横跨环氧化物的meoh加成所产生的产物外,还有大量的环状四氢呋喃衍生物,它们是由亚油酸甲酯(18:2)与meoh的反应衍生而来的.所有溶剂的特征在于高沸点和低蒸气压.它们的粘度高于大豆酸甲酯的粘度.尤其值得注意的是它们的贝壳杉醇丁醇值很高,介于280至852之间,所有这些都比大豆油甲酯的(57)高得多.如此高的kb值表明这些溶剂具有非常有利的增溶剂性能,这可由em

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.

摘要:Bio-based polymer precursors and non-isocyanate polyurethanes (NIPU) and non-isocyanate polyurethane foams (NIPUF) that can be formed from the precursors, as well as methods for the synthesis of the precursors and the polyurethane products are described. The bio-based polymer precursors are formed through functionalization of a bio-based polyol, e.g., lignin, with cyclic carbonates. The bio-based polyol starting materials need not be pre-processed and can include Kraft lignin. NIPU/NIPUF can be synthesized through a ring opening curing reaction of cyclic carbonates of the bio-based polyol precursor with diamines. The carbonates and diamines can include non-toxic bio-based carbonates.
