标 题 :Improved process for synthesis of hindered amine stabilizers for polymeric materials
发明人：LAI JOHN TA-YUAN
权利人:GOODRICH CO B F
摘要:Process for the synthesis of hindered polysubstituted α-amino acetamides by reaction of a secondary amine with an α-halo acetamide in a basic organic reaction medium and in the presence of a phase transfer catalyst. The product thus obtained can comprise a multifunctional compound having one or more hindered amino moieties. These compounds are highly effective as UV stabilizers in a variety of plastics, especially the alpha monoolefins.

标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Acid catalyzed synthesis of methyl acrylate from acrylic acid and methanol
发明人：CHAKRABARTI REETAM; NGO MINH N; ELDER JAMES
权利人:ROHM & HAAS
摘要:A method for preparing methyl acrylate comprises:a) heating in a reaction zone a mixture comprising acrylic acid, methanol, and an acid catalyst to react and form a reaction product comprising methyl acrylate which is vaporized with other light components and then fed to a distillation zone, wherein a feed stream entering the reaction zone comprises methanol to acrylic acid in a molar ratio of greater than 1 and less than 2, and a residence time in the reaction zone ranges from 0.25 to 2 hours;b) condensing and phase-separating a distillate from the distillation zone to form an organic phase comprising methyl acrylate and an aqueous phase;c) returning a portion of the organic phase to the distillation zone as organic reflux; andd) feeding the remainder of the organic phase and the aqueous phase of the distillation zone to an extraction column to form a methanol rich aqueous effluent and an organic effluent comprising methyl acrylate.
