  • Is tributyl citrate a renewable plasticizer?
  • 4. Conclusions Tributyl citrate (TBC), a renewable plasticizer was synthesized by esterification of renewable citric acid (CA) and n -butanol over various zeolites. Amongst studied, 2% (w/w) P/USY zeolite was observed to be most active with 100% CA conversion and 93% TBC yield.
  • Which catalyst is used to synthesis tributyl citrate (TBC) plasticizer?
  • Esterification of citric acid (CA) to tributyl citrate (TBC) plasticizer was performed. USY and phosphonated USY catalysts were used for TBC synthesis. Phosphonated USY showed higher catalytic activity than parent USY. 2% (w/w) P/USY catalyst exhibited 100% CA conversion and 93% TBC yield.
  • Is catalytic synthesis of non-toxic/eco-friendly tributyl citrate (TBC) plasticizer?
  • The catalytic synthesis of non-toxic/eco-friendly tributyl citrate (TBC) plasticizer by esterification of renewable citric acid (CA) with butanol would be completely sustainable route. In this context, catalytic performance of parent ultra stable Y (USY) and phosphonated USY catalysts were investigated for TBC synthesis.
  • Can 2% p/USY catalyst be used for synthesis of non-toxic TBC plasticizer?
  • Hence, the use of 2% (w/w) P/USY catalyst for synthesises of non-toxic TBC plasticizer by esterification fermentation derived CA and butanol would be sustainable and environmentally benign catalytic process, in the context of complete CA conversion (100%) and high TBC yield (93%), long term stability and reusability of catalyst (5 reaction cycles).
  • How big is the plasticizers market?
  • 1. Introduction Recently, the plasticizers market is growing worldwide, as projected by latest statistical data at about 11 billion pounds per year of which, 2.4 billion pounds is shared by the United States (U.S.) (Kolah et al., 2007, Kolah et al., 2008, Nandiwale et al., 2015).
  • How is TBC synthesized?
  • Traditionally, TBC has been synthesized mainly over sulfuric acid and titanate (Xu et al., 2010, Xu et al., 2011, Yang et al., 2014). The homogeneous catalysts like sulfuric acid which has many drawbacks such as high by product formation, corrosion of equipment and also reinforced by environmental policies.
