Chemical properties and antioxidant activity of a water
The purified DOP was grounded with KBr powder and pressed into a 1 mm pellet for FTIR determination in the range of 4000–400 cm 1 [27]. 2.7. Periodate oxidation and Smith degradation. Periodic acid oxidation is a widely method for carbohydrate chemistry to lean the patterns of substitution, frequency, and degree of branching.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed. Unlike other reported methods, this approach increases the interaction between...
Using dried orange pulp in the diet of dairy goats: effects
Although dried orange pulp (DOP) may conveniently replace cereals in ruminant diets, few studies have considered similar diet substitution for goats. We hypothesised that DOP could replace cereal-based concentrate in goat diets without detrimental effects on growth performance and carcass quality of suckling kids and milk performance and blood
Study on Dendrobium officinale O-acetyl-glucomannan
The four major resultant fractions F20-30, F30-40, F40-50, and F50S had high purity. F20-30 and F30-40 had low polydispersity, which was suitable for batch mode light scattering study. Fractions obtained in solution with higher ethanol concentration tended to have higher Man/Glc ratio, higher degree of substitution of O-acetyl group, lower

- What is the difference between DOP and des?
- Moreover, DOP and DES remain in the ester and DES phases, respectively, which benefits the product purification and DES recycle. As a result, DOP with high purity of 99.01 wt% can be acquired from the bottom of T1, after purifying the crude product in the ester phase of D3.
- Is DOP better than RoHS?
- RoHS also has the same limits. In Japan it is less than 0.05% or 500 ppm. It is therefore necessary to use its cost-effective replacement, as good as DOP, possibly better that DOP,without causing health problems. Besides, it should be able to accept secondary plasticizer CP, without health hazard.
- Is DOP a good plasticizer?
- Plasticizing efficiency of DOP is considered as “1” and efficiency all other plasticizers is evaluated with reference to DOP. Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns.
- Is MCCP a good replacement for DOP?
- Interestingly MCCP is accepted by REACH specifications. MCCPwith 52% chlorine is good. One such replacement is citrate-based plasticizer, but experience is that when CP is blended with it at the same level as in DOP, the CP migrates to the surface of product in due course.
- Which is better DOP or DINP?
- DINP has a highermolecular weight and longer carbon chain,(Av. Molecular weight 418) as compared to DOP, molecular weight 390. This results in – Better aging performance, increasing product life. Higher high temperature resistance. 5. Other benefits of DINP over DOP - Electrical insulation performanceis better than DOP.
- Can halogen-free deep eutectic solvent synthesize DOP?
- Conclusion Taking the concept of process intensification, the reactive extraction strategy is for the first time proposed to synthesize DOP, using the halogen-free deep eutectic solvent [Im:2PTSA]. First, the catalytic and solvent effect of [Im:2PTSA] are experimentally affirmed.
