    摘要:
    尼古丁酸四氢呋喃基酯是通过将尼古丁酸或其反应性衍生物(如卤化物、酸酐、酯或腈)与四氢呋喃基醇或其反应性衍生物(例如金属衍生物)反应制备而成。反应方法已知能够从羧酸和醇或其反应性衍生物中产生酯。另外,该酯也可通过脱羧化3-吡啶羧酸四氢呋喃基酯-2-羧酸来制备,适当加热存在或不存在催化剂的情况下进行。3-吡啶羧酸四氢呋喃基酯-2-羧酸可通过将喹啉酸酐与四氢呋喃基醇反应获得,并且可以直接脱羧化为所需的尼古丁酸酯而不进行分离。该产品用作治疗剂。在实例中:(1)四氢呋喃基醇与尼古丁酸氯化物反应以生成尼古丁酸酯,而不是酸氯化物,可以使用酸酐或自由酸,在氯化氢存在下,而代替醇,则可以利用其钠衍生物;(2)喹啉酸酐和四氢呋喃基醇一起加热以形成3-吡啶-2:3-二羧酸酯,然后升高温度,可选添加铜粉作为催化剂,以进行脱羧作用,从而得到四氢呋喃基尼古丁酸酯。

    公开(公告)日:2020-12-22
    Hydrogel compositions are provided (a) that have a continuous hydrophobic phase and a discontinuous hydrophilic phase, (b) that have a discontinuous hydrophilic phase and a continuous hydrophilic phase, or (c) that are entirely composed of a continuous hydrophilic phase. The hydrophobic phase, if present, is composed of a hydrophobic polymer, particularly a hydrophobic pressure-sensitive adhesive (PSA), a plasticizing elastomer, a tackifying resin, and an optional antioxidant. The discontinuous hydrophilic phase, if present, is composed of a crosslinked hydrophilic polymer, particularly a crosslinked cellulosic polymer such as crosslinked sodium carboxymethylcellulose. For those hydrogel compositions containing a continuous hydrophilic phase, the components of the phase include a cellulose ester composition or an acrylate polymer or copolymer, and a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding thereto. Films prepared from hydrogel compositions containing or entirely composed of the aforementioned continuous hydrophilic phase can be made translucent, and may be prepared using either melt extrusion or solution casting. A preferred use of the hydrogel compositions is in wound dressings, although numerous other uses are possible as well.
