2-Ethylhexyl acrylate is obtained by esterification of acrylic acid (AA) with 2-ethylhexanol (2-EtHexOH), in the presence of at least one stabilizer for AA, with H 2 SO 4 as catalyst, the crude reaction mixture (B1) obtained comprising the desired acrylate, 2-EtHexOH, AA, 2-...
The kinetic studies of the esterification of acrylic acid with 2-ethylhexan-1-ol have been rarely reported as well. Nowak [26] and Grzesik et al. [27] studied the kinetics of liquid phase synthesis of 2-ethylhexyl acrylate catalyzed by sulfuric acid. Based on the amount of catalyst and the...
In a process for esterifying (meth)acrylic acid with an alkanol in the presence of an acidic esterification catalyst, in which unconverted starting compounds and the (meth)acrylates to be formed are separated off by distillation and an oxyester-containing bottom product is formed, the bottom pro...

of Industrial Chemistry, 6th ed, 1999 Electronic Release, Chapter: Acrylic Acid and Derivatives—Esterification, a process for the preparation of higher alkyl acrylates is described which is carried out in the presence of an organic solvent as an entraining agent and sulfuric acid as a catalyst....
Homogenous acid-catalysed esterification of acrylic acid (AA) with 2-ethylhexanol (2EH) is commonly used for the production of 2EHA. The homogeneous catalysts such as sulfuric and para-toluene sulfonic acid have resulted the costly and... MAA Ahmad,SY Chin 被引量: 0发表: 2017年 A catalyst...
A process for converting a salt of a hydroxycarboxylic acid to an unsaturated carboxylic acid, or esters thereof. The process involves converting an ammonium salt of a hydroxycarboxylic acid in aqueous solution to a corresponding hydroxycarboxylic acid and ammonium cation in aqueous solution; and sep...
