Sensitive monitoring of the main metabolites of tri-(2
Tri-(2-ethylhexyl) trimellitate (TOTM or TEHTM) is a substitute for the plasticizer di-(2-ethylhexyl) phthalate (DEHP). Here, a fast and sensitive UHPLC-MS/MS method is presented enabling the simultaneous quantification of the six main TOTM metabolites in urine. These include the primary metabolites
Structure and Diffusion Behavior of Trioctyl Trimellitate
Tri-2-ethylhexyltrimellitate (TOTM) is one of the commercially used plasticizers for poly (vinyl chloride) (PVC). In this work, the diffusion behavior of TOTM in PVC films is investigated through real-time ATR-IR spectroscopy at 25, 40, and 70 °C, and the ratio changes of three C═O structures of TOTM are plotted as a function of diffusion time.
Structure and Diffusion Behavior of Trioctyl Trimellitate
Furthermore, another new band related to C═O groups of TOTM was observed during diffusion experiments in PVC at different temperatures, which can be assigned to dipolar–dipolar interactions between TOTM and PVC (interacting C═O structure). These results show that the diffusion coefficients of TOTM in PVC increase with temperature.
CPSC Staff Statement on University of Cincinnati Report
When trimellitate esters, such as TOTM, are processed with PVC, their principle feature is low volatility, even under high temperatures. Consequently, TOTM’s main use is in high specification electrical cable insulation and sheathing (ECPI, 2009, as cited by Versar, 2010). Additionally, as a branched molecule, TOTM is more viscous than the
Trioctyl Trimellitate (TOTM) - Chemical Supplier Distributor
Trioctyl Trimellitate (TOTM) is a high molecular weight, branched plasticizer used for PVC applications in which the end-use requires extreme low volatility. Such applications can include vinyl automotive interior or molded parts, dishwasher gaskets, seals, and telephone wire.
