Effect of Reactive Distillation on the Yield of Tetraacetylethylenediamine (TAED)

Abstract

Determination of acetic anhydride and acetic acid concentrations in the distillate withdrawn from the distillation columnA mixture of acetic acid and acetic anhydride was charged in the reactor and subjected to distillation with total reflux. The mole fraction of acetic acid in the reflux was determined by using a refractometer (ATAGO, Model 3T) and a gas-chromatograph (Hewlett Packard,

Comparison of four oxidants activated through tetraacetylethylenediamine for developing sustainable and rapid degradation of organic dye

“…Similarly, TAED could also activate SPB because it could undergo hydrolysis in the presence of water, producing hydrogen peroxide and borate, as shown in Equation 5, 27 which led to the generation of PAA molecules in the TAED/SPB system. Also, it was reported that the combination of TAED with SPC or SPB, especially in washing‐machine detergents, was able to effectively oxidise various chemical and biological compounds 20,28,46 . Meanwhile, peracetate was itself converted to acetate in these reactions 20 .…”

Saving the Energy Loss in Lithium‐Mediated Nitrogen Fixation by Using a Highly Reactive Li3N Intermediate for C−N Coupling Reactions

“…Imides are highly important organic structures that are extensively found in various pharmaceuticals, natural products, and electrically conductive materials [19, 20] . Present methods for synthesis of imides most frequently utilize acylation of amides with acid chlorides in the presence of super‐stoichiometric amounts of strong bases [21, 22] .…”

“…Imides are highly important organic structures that are extensively found in various pharmaceuticals, natural products, and electrically conductive materials. [19,20] Present methods for synthesis of imides most frequently utilize acylation of amides with acid chlorides in the presence of super-stoichiometric amounts of strong bases. [21,22] Amides again are synthesized from the acylation of ammonia or primary amines with activated forms of carboxylic acids, such as acid chlorides, anhydrides, and esters.…”

Transesterification of Methyl Acetate with Isobutanol in a Reactive and Extractive Distillation Column with Ionic Liquid as Catalyst and Molecular Liquid as Entrainer

“…Reactive distillation (RD) is an option for the transesterification of methyl acetate with isobutanol, which is limited by chemical equilibrium. High conversions of reactants and high purities of products can be achieved by removing the products from the RD column. − Therefore, many reversible reactions including esterification, − transesterification, ,, hydrolysis, ,, etherification, − and acetylation have been carried out in RD processes. In recent years, because of the excellent catalytic performance and easy recycling of ionic liquids, the RD process with ionic liquid as catalyst has attracted more attention.…”
