Bis(2-ethylhexyl) phthalate
DEHP is the most common phthalate plasticizer in medical devices such as intravenous tubing and bags, IV catheters, nasogastric tubes, dialysis bags and tubing, blood bags and transfusion tubing, and air tubes. DEHP makes these plastics softer and more flexible and was first introduced in the 1940s in blood bags.

Dioctyl phthalate - Bis (2-ethylhexyl) phthalate, DEHP
Dioctyl phthalate. C6H4-1,2-[CO2CH2CH(C2H5)(CH2)3CH3]2. Synonyms: Bis(2-ethylhexyl) phthalate, DEHP, DOP, Phthalic acid bis(2-ethylhexyl ester). CAS 117-81-7.
The role of chemical microstructures and compositions on the
Another study illustrated that the presence of 5 phr BT and 10 phr dioctyl phthalate (DOP) was optimum to exhibit an actuation performance of 11% at a pre-strain of 10%. However, increasing the BT content further resulted in the agglomeration that inhibited the final actuation performance.
Biochemical pathways and enhanced degradation of dioctyl
The degradation pathway of DEHP was analyzed by GC-MS. DEHP was decomposed into phthalates (DBP) and Diuretic sylycol (DEP), then further to Phthalic acid (PA). PA was oxidized, dehydrogenated, and decarboxylated into protocatechins, further entered the TCA cycle through orthotopic ring opening.
- What is dioctyl phthalate (DOP)?
- 1. Introduction Dioctyl phthalate (DOP) is one of the most widely used plasticizers with low volatility and high plasticizing efficiency. Although new product like dioctyl terephthalate is more recommended, DOP accounts for more than half of the market share for plasticizers.
- What is phthalic anhydride (PA) and 2-ethylhexanol (eh)?
- It has been generally utilized for the flexible polyvinyl chloride (PVC) plastic production owing to its low cost. DOP is traditionally synthesized by the catalytic esterification between phthalic anhydride (PA) and 2-ethylhexanol (2-EH) . The synthetic process includes two-step reactions of esterification: (1) (2)
- What is the polarity of DOP?
- As exhibited in Fig. 3, the σ -profile of DOP is mostly distributed within the range of −0.0084 e/Å 2 < σ < 0.0084 e/Å 2 and only a weak peak exists near the non-polar region, suggesting its very weak polarity.
- Where can I buy phthalic anhydride and p-toluenesulfonic acid?
- Materials Dioctyl phthalate, phthalic anhydride, 2-ethylhexanol, n-tridecane, choline chloride, imidazole, and p -toluenesulfonic acid are purchased from Adamas-beta (Shanghai, China) with purity above 99%.
- Can halogen-free deep eutectic solvent promote DOP synthesis in a biphasic system?
- In this work, the process intensification of reactive extraction strategy is proposed to promote DOP synthesis in a biphasic system, with the halogen-free deep eutectic solvent (DES) [Im:2PTSA] as dual solvent-catalyst.
- How does 2-eh affect DOP yield?
- The excess of 2-EH can speed up the attainment of phase splitting, which is favorable for the forward reaction and hence increasing DOP yield. However, phase splitting will reduce the possibility of contact between reactants and DES, which delays the reaction to attain chemical equilibrium. 5.2. Kinetic modelling
