Screening of Catalyst and Important Variable for the Esterification of Acrylic Acid with 2 Ethylhexanol

The global demand of 2-ethylhexyl acrylate (2EHA) market has witnessed a significant growth in the past few years and this growth is anticipated to increase in the coming years. 2EHA is one of the basic organic building blocks that mainly used in the production of coatings, adhesives, superabsorbent...
