Occurrence, distribution, and sources of phthalates and non
Di(2-ethylhexyl)phthalate (DEHP) and trioctyl trimellitate (TOTM) were the dominant for phthalates and NPPs, respectively, implying emerging contamination by TOTM. Spatial distribution of these contaminants showed decreasing gradients from inner to outer bays.
CPSC Staff Statement on University of Cincinnati Report
The structure of TOTM is similar to that of di(2-ethylhexyl) phthalate (DEHP), with the exception that TOTM contains a third functionality on the aromatic ring. The presence of three alcohols makes trimellitates significantly more viscous then adipates or phthalates (Hatco, 2008, as cited by Versar, 2010). TOTM is an EPA High Production
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.
Exposure of hospitalised pregnant women to plasticizers
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).
Accelerated Solvent Extraction of Plasticizers from Polyvinyl
using accelerated solvent extraction to extract plasticizers such as dioctyl adipate (DOA), trioctyl phosphate (TOP), dioctyl phthalate (DOP), and trioctyl trimellitate (TOTM) from PVC.

- What is Trioctyl trimellitate (TOTM)?
- Trioctyl trimellitate (TOTM) is a colourless, transparent oily liquid with a boiling point of 283℃ (3mmHg) and a viscosity of 100–300 c.p. (20℃). It has a refractive index of 1.4485 (25℃). TOTM is used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride. It is typically used for preparing plastics.
- What is TOTM plasticizer?
- lit. 283. lit. 46. 272-277. 250. 1.483–1.487. TOTM is almost colourless and oily liquid, free of foreign materials TOTM is a primary branched monomeric plasticizers for vinylhomopolymer and Copolymer resins. TOTM is suggested for use in those end-use areas where Extreme low volatility is required.
- What is trioctyl trimellitate?
- Trioctyl Trimellitate is a primary plasticizer for polyvinyl chloride resin and copolymer applications. It offers compatibility, excellent low temperature properties, ease of processing and a high degree of permanence.
- What is plasthall TOTM?
- Plasthall TOTM provides very low compound weight losses, exceptional retention of original elongation after air oven aging and excellent extraction resistance to a variety of polar and non-polar fluids. These properties abound for the broad usage of Plasthall TOTM in PVC wire and cable insulation and vinyl automotive interior trim.
- What is the refractive index of trioctyl trimellitate?
- The refractive index of trioctyl trimellitate (TOTM) is 1.4485 (25°C). TOTM is used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride, usually for preparing Grade 105°C electrical cable and other heat-resisting plastic products. It possesses both advantages being used as a plasticizer for polyesters and for general purposes.
- Which trimellitate is the most efficient?
- Of the trimellitate family, Plasthall TOTM is the most efficient. The information presented herein is believed to be accurate and reliable, but no warranty or guarantee, expressed or implied, is made regarding the information or the performance of any product.
