  • Process for the preparation of halogenated (meth)acrylic esters and poly (meth) arcylates obtained with said (meth)acrylic esters
    申请人:Akzo Nobel N.V.
    公开号:EP0824096A2
    公开(公告)日:1998-02-18
    The present invention is directed to a process for the preparation of (meth)acrylates of halogenated alcohols by direct esterification of said alcohols with (meth)acrylic acid (chloride) wherein at least 2,6-substituted pyridine derivative is used as a polymerization inhibitor at room temperature or lower. Suitable at least 2,6-substituted pyridine derivatives are 2,6-lutidine, 2,4,6-collidine or 2,6-di-tert.butyl-4-methyl pyridine. With the halogenated (meth)acrylate esters prepared with the process according to the invention, very pure homo- and copolymers can be prepared, resulting in polymers having a low optical loss of 0.1 dB/cm or lower at 1300 nm and lower than 0.4 dB/cm at 1550 nm.
    本发明涉及一种通过将卤代醇与(甲基)丙烯酸(氯化物)直接酯化来制备(甲基)丙烯酸酯的方法,其中至少使用一种2,6-取代吡啶衍生物作为聚合抑制剂,温度为室温或更低。适用的至少2,6-取代吡啶衍生物包括2,6-吡啶、2,4,6-考林或2,6-二叔丁基-4-甲基吡啶。 通过根据本发明的方法制备的卤代(甲基)丙烯酸酯,可以制备非常纯净的同聚物和共聚物,从而得到在1300纳米处光学损耗低至0.1 dB/cm或更低,在1550纳米处低于0.4 dB/cm的聚合物。

    Potential of polyfluoroaromatic compounds containing OH, COOH, and mixed H-donor functions as co-formers in co-crystallization with 18-crown-6 ether was explored. Pentafluorophenol, 1,3- and 1,4-dihydroxytetrafluorobenzenes and pentafluorobenzoic acid form with 18-crown-6 hydrated co-crystals containing one water molecule per H-donor group upon contact of the solutions with atmospheric moisture; pentafluorophenol
    探索了含有OH,COOH和混合的H-供体的多氟芳族化合物在与18-冠-6醚共结晶中作为共形成剂的潜力。当溶液与大气中的水分接触时,五氟苯酚,1,3-和1,4-二羟基四氟苯与五氟苯甲酸与18个皇冠6个水合共晶体形成一个水分子,每个H供体基团含有一个水分子。五氟苯酚产生的共晶体与在EtOH水溶液中的水量加倍。氨基四氟苄醇和氨基四氟苯甲酸能够与18-crown-6形成无水1:1和2:1共结晶。在结晶水合物中,共形成物分子通过水介导的合成子[C(O)] O H⋯O(H)H⋯O cr连接。根据量子化学计算,每个水连接分子参与H键合将超分子结构的稳定性提高约100kJ mol -1。双官能团的缔合体表现出H键合的1D组装作为唯一的结构决定基元。在共晶的单官能芳烃的分子通过结合π ˚F ⋯π ˚F堆叠,得到H-粘结/π堆叠1D组件。计算出的π-堆积能取决于H-给体功能(NH 2,OH,COOH)的性质,随着分子偶极矩的减小而减小。

    The present invention relates to a method for manufacturing an ester from a ketone or an aldehyde, which is a reactive substrate, by a Baeyer-Villiger oxidation reaction using hydrogen peroxide, and in this method, as a catalyst, M(BAr 4 ) n , which is a metal borate, is used (M represents an alkali metal or an alkaline earth metal; Ar represents an aryl; and n is the same number as the valence of M). For example, when cyclohexanone was used as the reactive substrate, and Sr[B(3,5-CF 3 C 6 H 3 ) 4 ] 2 was used as the catalyst, ε-caprolactone was obtained at an isolated yield of 82%.
