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.

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.

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).
Analysis of PVC plasticizers in medical devices and
The most common safer plasticiser alternatives to phthalates are tri-octyl trimellitate (TOTM), di-isononyl cyclohexane-1,2dicarboxylate (DINCH), di-isononyl phthalate (DINP), di- (2ethylhexyl)...

Applications of Trioctyl Trimellitate. Trioctyl trimellitate can be used in various plastic materials such as polyvinyl chloride (PVC), chloroethylene copolymer, ethyl cellulose and polymethyl methylacrylate. TOTM is an excellent substitute for polyester polymeric plasticizers due to the improvements in processing it offers.
- 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.
- 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.
- 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.
- Is trioctyltrimellitate hazardous to water?
- Trioctyl trimellitate is considered to be slightly hazardous to water and should not be released into soil, water bodies or waste water. Trioctyltrimellitate (TOTM) offers high resistance to heat, making it a versatile plasticizer for durable and heat-resistant plastics in a wide range of applications.
