• Process for producing 4,4,4,- trifluoro-3-hydroxybutyric acid
  申请人：CENTRAL GLASS COMPANY, LIMITED

  公开号：US20030088095A1

  公开（公告）日：2003-05-08

  A first process for producing an optically active perfluoroalkylcarbinol derivative includes (a) reacting an optically active imine with a compound that is a hemiacetal of a perfluoroalkylaldehyde or a hydrate of a perfluoroalkylaldehyde to obtain a condensate; and (b) hydrolyzing the condensate under an acid condition. A second process for increasing optical purity of an optically active 4,4,4-trifluoro 3-hydroxy-1-aryl-1-butanone derivative includes (a) precipitating a racemic crystal of the derivative, from the derivative; and (b) removing the racemic crystal from the derivative. A third process for increasing optical purity of the butanone derivative includes recrystallizing the derivative. Novel compounds are optically active and inactive 4,4,4-trifluoro-3-hydroxybutanoic aryl ester derivatives. A fourth process for producing an optically active or optically inactive 4,4,4-trifluoro-3-hydroxybutyric acid aryl ester derivative includes oxidizing an optically active or optically inactive 4,4,4-trifluoro-3-hydroxy-1-aryl-1-butanone derivative. A fifth process for increasing optical purity of the optically active aryl ester derivative includes recrystallizing the derivative. A sixth process for producing an optically active 4,4,4-trifluoro-1,3-butanediol includes reducing the optically active aryl ester derivative by a hydride. A seventh process for producing an optically active or inactive 4,4,4-trifluoro-3-hydroxybutyric acid alkyl ester derivative includes reacting under an acid condition the optically active or optically inactive aryl ester derivative with a lower alcohol. It is possible to suitably combine at least two of the first to seventh processes.

• Polymerization inhibitor and retarder compositions with amine stabilizer
  申请人：Ecolab USA Inc.

  公开号：US11180578B2

  公开（公告）日：2021-11-23

  Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition, which use an N—O polymerization inhibitor, a quinone methide polymerization retarder, and an amine stabilizer having a primary and/or secondary amine group. In a mixture, the amine-based stabilizer can prevent antagonistic effects and can provide greater antipolymerant activity. In turn, the mixture inhibits apparatus fouling and improves the purity of monomer streams.

  描述了抑制单体（如苯乙烯）组合物聚合的组合物和方法，其中使用了一种 N-O 聚合抑制剂、一种醌甲醚聚合延缓剂和一种具有伯胺和/或仲胺基团的胺稳定剂。在混合物中，胺基稳定剂可以防止拮抗作用，并提供更强的抗聚合活性。反过来，混合物可抑制装置堵塞，提高单体流的纯度。
