Chemical properties and antioxidant activity of a water
In this report, due to the relatively high viscosity of DOP aqueous solution, the COSY and TOCSY spectra were too noisy to give more useful structural information (spectrum not shown). Therefore, our discussion focuses on the anomeric signals at δ105.29, 102.91, and 101.88 ppm in 13 C NMR spectrum of DOP.
Development of a Red Persistent Luminescent Composite
The emission spectrum showed a broad band centered at 615 nm, attributed to the 4f 6 5d 1 (t 2g)→4f 7 transition of Eu 2+, where the broadening was due to interactions of the 5d orbital with the chemical environment. The covalent character of the SrS matrix generated a strong nephelauxetic effect, with significant overlap between the 5d
- 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 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.
- Who is spectrum chemical?

- What is chemical doping?
- Chemical doping is a key process for investigating charge transport in organic semiconductors and improving certain (opto)electronic devices 1, 2, 3, 4, 5, 6, 7, 8, 9. N (electron)-doping is fundamentally more challenging than p (hole)-doping and typically achieves a very low doping efficiency (η) of less than 10% 1, 10.
- 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 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.
