In the phase interface, the adipate has slightly stronger binding capacity with gasoline which causing the decrease of the gasoline evaporate by bonding with the methanol molecules to form the low-boiling azeotrope.
Development of the Adipates as Bifunctional Additive in Methanol-Gasoline
ProSolv like many other fluorinated solvent azeotropes is extremely effective for precision cleaning in high-tech industries such as aerospace, aviation, electronics and medical due to the use of an additive trans 1,2-dichloroethylene.
Solving the problem
But, this reaction cannot be carried out at 70[degrees]C as THF/water azeotrope at 65[degrees]C.
He who hesitates is lost; hesitation in the drive to a continuous pharmaceutical manufacturing process: real or imaginary?
After fermentation, water is removed from the fermented wine solution by distillation, but the purity is limited to ~96% (hydrated ethanol, 96[degrees]GL, Gay-Lussac) due to the formation of a low-boiling water-ethanol azeotrope. It is important to note that the 96[degrees]GL ethanol may be used directly as fuel by specially designed Brazilian cars (Moreira and Goldemberg, 1999).
Potential emissions of Kyoto and non-Kyoto climate active compounds in the production of sugarcane ethanol/Emisiones de compuestos, incluidos o no en el protocolo de Kyoto, climaticamente activos, durante la produccion de etanol de cana de azucar/Emissoes de compostos, incluidos ou nao no protocolo de Kyoto, climaticamente ativos, durante a producao de etanol de cana de acucar
Except for R-436A and R-436B, others are either azeotrope or near-azeotropes.
Energy and environmental crisis: let's solve it naturally in refrigeration and air conditioning
Due to inefficient stripping and the formation of an azeotrope at 38.26 wt% HF in water (Munter et al., 1947), a significant part of the fluorine losses are in the form of HF in the acid re-run bottoms; this is considered in greater detail below.
Assessment of cleaner process options: a case study from petroleum refining
It can be run without a solvent, but is faster and more reproducible in the presence of a solvent such as xylene, which forms an azeotrope with water.
Waterborne silicone-organic hybrid coatings for exterior applications
These solvents form an azeotrope with a boiling point close to that of ethyl acetate, and thus the solvent keeping approach would not work.
Improving analysis of pesticides: a new method development protocol increases recovery of volatile compounds
An azeotrope was prepared, (halothane/ether 2/1, boiling point 51.5[degrees]C).
The introduction of halothane into clinical practice: the Oxford experience
Some cosolvents like iso-propanol can form an azeotrope with water to lower the mixtures total boiling point temperature and therefore evaporation of water is aided.
High-performance waterborne coatings for heavy-duty corrosion protection: exploring three waterborne technologies for heavy-duty corrosion protection
Starting at 190[degrees]C, a xylene-water azeotrope was collected overhead.
