- CYCLOHEXANE TRIESTER BASED PLASTICIZER COMPOSITION AND RESIN COMPOSITION COMPRISING THE SAME
-
Provided is a plasticizer composition which includes, as cyclohexane triesters, a lower non-hybrid-type cyclohexane triester, a lower hybrid-type cyclohexane triester, a higher hybrid-type cyclohexane triester, and a higher non-hybrid-type cyclohexane triester, wherein the alkyl groups applied thereto are a combination of a C3-C6 alkyl group and a C7-C10 alkyl group. When applied to a resin, the plasticizer composition allows stress resistance and mechanical properties to be maintained at an equivalent level or improved, migration properties, volatile loss characteristics, and plasticization efficiency to be balanced, and light resistance and heat resistance to be significantly improved.

- Micro-flow nanocatalysis: synergic effect of TfOH@SPIONs and micro-flow technology as an efficient and robust catalytic system for the synthesis of plasticizers
-
The combination of continuous flow technology with immobilizing of only 0.13?mol% of triflic acid (TfOH) on silica-encapsulated superparamagnetic iron oxide nanoparticles (SPIONs) under solvent-free conditions successfully provided a powerful, efficient, and eco-friendly route for the synthesis of plasticizers. The turnover frequency value in micro-flow conditions varied in the range of 948.7 to 7384.6 h?1 compared to 403.8 to 3099 h?1 for in-flask. This technique works efficiently, encouraging future applications of micro-flow nano-catalysis in green chemistry.

- Synthesis of carboxylic acid esters in the presence of micro- and mesoporous aluminosilicates
-
The catalytic properties of zeolites HY, HBeta, and HZSM-12 and of mesoporous amorphous aluminosilicate in liquid-phase esterification of aliphatic (monobasic C1-C18, dibasic C6, C10) and aromatic (benzoic, trimellitic, phthalic) carboxylic acids with butanol were studied. Zeolite HBeta appeared to be the most active catalyst. Procedures were developed for preparing esters in the presence of zeolitic catalyst HBeta, ensuring 100% selectivity of ester formation at 90-98% conversion of the acid.
