  • Can a benzoate plasticizer be produced based on a fraction isolated from EDR?
  • The purpose of the work was to study the possibility of producing a benzoate plasticizer based on a fraction isolated from EDR and enriched with 2,4-diethyl-1,3-octanediol.
  • What is the composition of benzoic acid esters in polyvinyl chloride?
  • As a result of research, a product was synthesized containing 76.2% of benzoic acid esters, including 53.1% of mixture of 2,4-diethyl-1,3-octanediol monobenzoates and monoalcohols C 8, C 12, and 23.1% of 2,4-diethyl-1,3-octanediol dibenzoate. The product exhibited good compatibility with polyvinyl chloride and plasticizing properties.
  • How is benzoate plasticizer prepared?
  • Method of benzoate plasticizer preparation. A three-necked round-bottom flask equipped with a thermometer and a reflux condenser with a Dean–Stark attachment was charged with 310.10 g of the alcohol fraction and 97.70 g (0.8 mol) of benzoic acid.
  • Which plasticizers are used in polyvinyl chloride compositions?
  • In the industry, based on glycols, predominantly dibenzoate plasticizers (for example, the trade mark Benzoflex) are produced, which are utilized as secondary solvating plasticizers in polyvinyl chloride compositions.
  • What is a benzoflex plasticizer?
  • The plasticizer can be composed of a mixture of different dibenzoates. For example, Benzoflex 2088 includes dipropylene glycol, di- and triethylene glycol dibenzoates. Monobenzoates, such as 2-ethylhexyl benzoate (Benzoflex 181) or isodecyl benzoate (Benzoflex 131), are used to adjust the viscosity in PVC plastisols.
  • Do plasticizers deteriorate the thermal stability of plasticized PVC?
  • When plasticized samples were subjected to the same temperature ramp, dramatic differences were observed compared to the above results for the plasticizers alone. Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied.
