Production mode of plasticizer – ZhangJia Gang YaRui

Continuous production is suitable for raw material sources, with high production management level and high quality of personnel. Production mode of plasticizer: semi continuous production The so-called semi continuous production means that the chemical order of the ester is intermittent, and the process after esterification (neutralization, dealcoholization, decolorization and filtration) is Semi-continuous Production of 2-Ethyl Hexyl Ester in a Packe The aim of this work was to investigate the technical as well as the economic feasibility of producing 2-ethyl hexyl oleate (2-EHO), a non-phthalate plasticizer in a solvent free medium. The esterification reaction between oleic acid and 2-ethyl hexyl alcohol was carried out in a packed bed reactor (PBR) using Candida antarctica lipase B (Novozym 435; Novozymes; Copenhagen-Denmark) as biocatalyst.
