Trioctyl trimellitate 99 3319-31-1 - Sigma-Aldrich
Trioctyl trimellitate (TOTM) is a flammable plasticizer used to improve the flexibility and durability of poly (vinyl chloride) (PVC). [ 1] [ 2] Application TOTM can plasticize PVC to form a nanocomposite with multi-walled carbon nanotube which can be potentially used for anti-static applications.

Structure and Diffusion Behavior of Trioctyl Trimellitate (TOTM) in PVC
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.

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.
Toxicity Review of TOTM - CPSC.gov
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

Analysis of medical devices (MDs) The results of the GC-MS analyses of MDs in PVC are presented in Table 1.Trioctyl trimellitate (TOTM) was the predominantly detected plasticizer in multi-access infusion sets (35% or g of TOTM/100 g of PVC), extension tubes (30% or g of TOTM/100 g of PVC) and epidural infusion sets (35% or g of TOTM/100 g of PVC).
- What is the structure of trioctyl trimellitate (TOTM)?
- Structural formula of Trioctyl trimellitate (TOTM) As an ester of trimellitic acid, trioctyl trimellitate (TOTM) has a complex structure with the phenyl ring of this acid at its center. Trioctyl trimellitate is thus an aromatic compound.
- Is trioctyl trimellitate combustible?
- Trioctyl trimellitate (TOTM) is a plasticizer with high stability. The connection is basically combustible, but difficult to ignite and not explosive. When trioctyl trimellitate is burned and thermally decomposed, acrid fumes and noxious gases such as carbon monoxide are released.
- What is trioctyl trimellitate?
- The compound is obtained from trimellitic anhydride and 2-ethylhexanol in an acid catalyzed esterification process. Due to its high temperature resistance, low volatility and harmlessness to health, trioctyl trimellitate is suitable as a plasticizer for special applications and mainly replaces phthalates there.
- What is a low dose of trioctyltrimellitate (TOTM)?
- Trioctyltrimellitate (TOTM) is a high temperature application plasticizer, or when low volatility and high viscosity are important. It is an EPA High Production Volume chemical (HPVIS, 2008) with an estimated global production of 40,000-100,000 tons/year (SCENIHR, 2007). Doses below 1200 mg/kg-day are not specified in the provided text.
- What happens when trioctyl trimellitate is burned?
- When trioctyl trimellitate is burned and thermally decomposed, acrid fumes and noxious gases such as carbon monoxide are released. Trioctyl trimellitate (TOTM) reacts with strong oxidizing agents and acids. This can lead to reactions with intense heat development, so that the reaction products ignite.
- How does trioctyl trimellitate react with oxidizing agents?
- Trioctyl trimellitate (TOTM) reacts with strong oxidizing agents and acids. This can lead to reactions with intense heat development, so that the reaction products ignite. Explosive hydrogen, among other things, can form in contact with alkali metals and alkali hydrides.
