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.

Preparation of ECTFE porous membrane with a green diluent TOTM and
Trioctyl trimellitate (TOTM) has a better high-temperature resistance and volatile resistance, is an environmentally friendly diluent. In the previous reports, it was mainly employed as a plasticizer to replace dioctyl phthalate (DOP) for the polymer such as polyvinyl chloride (PVC) [ 37 , 38 ].
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.
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

Trioctyl Trimellitate. Trioctyl trimellitate (TOTM) is a clear oily liquid with a very slight odour. It is a primary branched monomeric plasticizer for vinyl homopolymer and copolymer resins which has extremely low volatility. It is a speciality plasticizer which offers a number of advantages such as good extraction resistance, good plasticizer
- What is trioctyl trimellitate (TOTM)?
- As a triple ester of trimellitic acid, trioctyl trimellitate (TOTM) belongs to the group of carboxylic acid esters and is mainly used in industry as a plasticizer in products made from polyvinyl chloride (PVC). The compound is obtained from trimellitic anhydride and 2-ethylhexanol in an acid catalyzed esterification process.
- 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.
- Is trioctyl trimellitate soluble in water?
- Trioctyl trimellitate (TOTM) is a clear, yellowish liquid with an oily consistency. The compound is practically insoluble in water, slightly soluble in the organic solvents chloroform and methanol. Trioctyl trimellitate is hardly volatile and can therefore also be used in sensitive areas of application.
- 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.
- 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.
- 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.
