Both competing reactions proceed via the same intermediates, keto esters, which either intramolecularly cyclize to the 1:1 adducts, or intermolecularly add the second molecule of cyanopropargylic
    摘要 首次表明,在微波辐射(MeCN,100°C,1.2 atm)下三乙胺(5–100 mol%)存在下,氰基炔丙醇与羧酸的反应遵循两条竞争途径生成4-氰基-3(2 H)-呋喃酮(1:1加合物)和4-氰基-[(Z)-3-氰基亚甲基] -2,3-二氢呋喃(2:1加合物),产率中等至良好。产物的比例取决于反应条件(反应物比例,催化剂含量)和反应物结构,其中2:1加合物的形成受氰基炔丙醇过量,催化剂含量较低和羧基官能团取代的影响。两种竞争反应均通过相同的中间体酮酸酯进行,该中间体在分子内环化为1:1加合物,或在分子间添加氰丙炔醇的第二个分子以生成2:1加合物。 首次表明,在微波辐射(MeCN,100°C,1.2 atm)下三乙胺(5–100 mol%)存在下,氰基炔丙醇与羧酸的反应遵循两条竞争途径生成4-氰基-3(2 H)-呋喃酮(1:1加合物)和4-氰基-[(Z)-3-氰基亚甲基] -2,3-

  • WATER BASED ANIONIC POLYMERS FOR INKJET INKS
    申请人:PENN COLOR, INC.
    公开号:US20140113990A1
    公开(公告)日:2014-04-24
    The present invention provides a durable, external surfactant free, anionic, water based jet ink polymer which when formulated into an ink jet ink results in a printing that has an excellent adhesion to metal or plastic substrates. Such a jet ink polymer is suitable performance replacement of solvent soluble polymers currently in commercial use. The hybridized copolymer comprises a hydrophobic functional polymeric backbone comprised of a polysiloxane polymer, a polyolefin polymer, or a functional polyvinyl polymer. The hybridized copolymer also comprises a plurality of copolymeric side chains attached to the backbone, comprising a polymerizable acid-containing unsaturated monomer, and a polymerizable unsaturated monomer. The use of the inks of the present invention enhances performance criteria such as print-head open time, ink stability, and resistance to typical water based cleaners.
