Epoxidation of styrene with NaOCl and catalyzed by nickel(II) complexes

, 1999
Epoxidation of styrene was catalyzed by some nickel(II) complexes, with NaOCl as the oxygen donor. The catalyst Ni(PA)(2). 2H(2)O has been found to be stable for the epoxidation of styrene.

Preparation of chitin nanofibers by surface esterification of chitin with maleic anhydride and mechanical treatment [PDF]

Esterification with maleic anhydride significantly improved the mechanical disintegration of chitin into uniform 10-nm nanofibers. Nanofibers with 0.25° of esterification were homogeneously dispersed in basic water due to the carboxylate salt on the ...

Esterification of butylene with acetic acid over HBeta zeolite cactalyst

, 2010
Carboxylic ester has been widely used to replace the aromatic solvents in the production of lacquers, inks and adhesives. Butyl acetate was usually produced by acetic acid reaction with butanol [1].

Selective aerobic radical epoxidation of alfa-olefins catalyzed by N-hydroxyphthalimide

, 2008
The combination of N-hydroxyphthalimide (NHPI) and peracids is employed for the free-radical epoxidation of alkenes with high yields. A quite different selectivity is obtained from that of the well-known epoxidation by peracids, which is attributed to a ...

Lipase mediated simultaneous esterification and epoxidation of oleic acid for the production of alkylepoxystearates

Journal of Molecular Catalysis B: Enzymatic, 2007
Epoxy alkylstearates were synthesized by lipase catalysed esterification and perhydrolysis followed by epoxidation of oleic acid in a one-pot process. Immobilized Candida antarctica lipase (Novozym 435) was used as the catalyst.

Alkene epoxidation with urea–hydrogen peroxide complex and PS–DVB supported phthalic anhydride

Tetrahedron Letters, 2005
A new PS-DVB supported phthalic anhydride and UHP (urea-hydrogen peroxide complex) have been used for metal-free alkene epoxidation reactions. The resin was prepared by MW mediated 'PEGylation' of Merrifield resin followed by esterification with ...
