Phthalate ester plasticizers in freshwater systems of Venda
The detection limits were determined for the phthalate ester plasticizers using the method described by Miller and Miller (1984). Quality assurance studies Water samples of 500 m (distilled and de-ionised water) were pre-extracted in triplicate with 3 x 20 m dichloromethane (DCM) in a glass separator funnel.
Synthesis of biosafe isosorbide dicaprylate ester plasticizer
In this study, biosafe isosorbide dicaprylate ester based plasticizer was prepared using renewable feedstock with lipase in a solvent-free system. Different kinds of water removal methods and some important factors including molar ratio of the substrates, reaction temperature and catalyst loading were investigated.
Ester plasticizers for polyvinyl chloride | SpringerLink
The review covers information from patents and papers that have been published in the past 5 years and deal with the synthesis of ester plasticizers for polyvinyl chloride. The main trends in the progress of this field are analyzed. Data on new esterification catalysts are presented. Particular attention is paid to plasticizers derived from terephthalic acid, which show promise for replacing
Preparation and Performance of Bio-Based Polyol Ester
The one-pot method had two stage, the first stage is to prepare castor oil based polyol (CP) using castor oil and glycidyl. The second stage is to synthesis castor oil based polyol ester (CPE) via esterification of CP and acetic anhydride. The toxicity of the obtained bio-based was investigated by acute oral toxicity test.
