Exceptionally active and reusable nanobiocatalyst comprising lipase non-covalently immobilized on multi-wall carbon nanotubes for the synthesis of diester plasticizers

A new method for the synthesis of dicarboxylic acid esters in the presence of a new heterogeneous nanobiocatalyst consisting of Candida antarctica lipase B immobilized on multi-walled carbon nanotubes (MWCNTs) has been developed. Selection and characterization of the support for Candida antarctica lipase B (CALB) was initially performed. Pristine and modified MWCNTs of different geometries, morphologies and surface/core modifications were tested as a lipase carrier and determining that the CheapTubes MWCNTs nanobiocatalyst with a 15.7 wt.% CALB loading was the most active nanobiocatalyst. The model reaction of succinic acid with n-butanol was carried out with a 4-molar excess of alcohol and 150 mg of nanobiocatalyst per 1 mmol of succinic acid at 45 °C in cyclohexane. The di-n-butyl succinate was obtained with 95% yield after 3 h. The activities of the new nanobiocatalysts were compared with the benchmark Novozyme-435 and other acidic catalysts. Recycling studies demonstrated the possibility of utilizing the most active MWCNTs-lipase biocatalyst six times without any significant loss of activity. The main advantage of this study is the superior activity of the new nanobiocatalyst, which resulted in a significant reduction of reaction times as compared to those reported in the literature.

Nano-SO42-/TiO2catalyzed eco-friendly esterification of dicarboxylic acids

Nano-SO42-/TiO2 was prepared by wet impregnation method. The structure and properties of the prepared nano-SO42-/TiO2catalyst was characterized by XRD, SEM, TEM and BET analysis. The catalytic activities of the catalysts were tested by the esterification of sebacic acid with 2-ethyl hexanol and a series of other dicarboxylic acid. The influence factors on the reaction, such as the catalyst calcination temperature, reaction temperature/time and the molar ratio of acid to alcohol were extensively explored. Nano-SO42-/TiO2prepared exhibited much higher catalytic activity in esterification reactions. By applying the optimized reaction condition, i.e. 160 C, 2 h, 5 wt % nano-SO42-/TiO2with a 1:3 molar ratio of sebacic acid to 2-ethyl hexanol, higher than 99 % isolated of the desired ester could be obtained.

Esters of 4-substituted 2-methyleneglutaric acids and method for preparing same

Esters of 4-substituted 2-methyleneglutaric acids are prepared by reacting an ester of acrylic acid with an ester of an α-substituted acrylic acid, such as an ester of methacrylic acid, in the presence of a tertiary organic phosphine, an organic phosphorus triamide, an organic phosphonous diamide, or an organic phosphinous amide.
