modeling, analysis and multi-objective optimization of an,tributyl citrate (tbc) is an environmentally-friendly and non-toxic plasticizer, which has been identified as a promising alternative to diethyl hexyl phthalate (dehp) for niche applications such.
- 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 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.
- 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% (W/W) P/USY catalyst be used for synthesis of TBC?
- The present method of using 2% (w/w) P/USY catalyst for the synthesis of TBC would be environmentally benign in the context of bio-renewable synthetic route, high catalytic activity, non-toxic product, long term stability and reusability of catalyst (five catalytic cycles).
- 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 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.
