Bis(2-ethylhexyl) phthalate
Bis (2-ethylhexyl) phthalate ( di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers. It is the diester of phthalic acid

5 Most important facts about Dioctyl phthalate (DOP)
Dioctyl phthalate (DOP), also known as diethylhexyl phthalate (DEHP), is an organic compound with the molecular formula C6H4 (CO2C8H17). Dioctyl phthalate, characterized by its molecular weight, high boiling point, and low vapor pressure, is one of the most widely used general emollients.
Dioctyl Phthalate (DOP) Plasticizer - Fengbai Group
DOP chemical is a general-purpose plasticizer. It is mainly used in the processing of polyvinyl chloride resin. It can also be used in the processing of high polymers such as chemical fiber resin, acetate resin, ABS resin and rubber, as well as paint making, dyes, dispersants, etc. General purpose dioctyl phthalate DOP.

- 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.
- 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.
- 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)
- 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%.
- 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.
- What is a high DOP yield after a three-stage reaction?
- At the condition of 130 °C (all reactors), 2-EH to PA mole ratio of 2.2 in PR, and DES mole fraction of 7.53 % (R1, R2 and R3), a high DOP yield of 98.61 % can be achieved after three-stage reactions. In Table 3, the composition of both phases in D1, D2 and D3 predicted by COSMO-RS were listed.
