By boiling point of them approximate the Re husband of ethyl acetate, will cause difficulties Te the purification of ethyl acetate product and butan-2-one n- butyl aldehyde, respectively 2 by it if it is some - it is hydrogenated to n- butanol and butanol. It is used to purify the ...
Its relative density is 1.0362 (25/4 °C), its melting point is -60 °C, and its boiling point is 188.2 °C. It is miscible with water, acetone, ethyl acetate and chloroform, and soluble in ether. Although it has little solubility for hydrocarbons, ...

phase was washed with water, dried over sodium sulphate and added to the toluenic phase. The solventwas evaporated off under reduced pressure and the residue was fractionated to give 23.8g of 2-(2-ethyl-3-benzofuranyl)-propionitrile (yield 74.4%, boiling point: 105.deg. C. at0.2 mmHg)...
The effect of propylene glycol ether properties on diesel fuel are the following; 1) modification of diesel distillation curve mainly at low temperatures, the higher variation taking place at temperatures near to boiling point of the corresponding oxygenated compound; (2) viscosity reduction; (3) ...
For inorganic salts with strong hydrophilicity, evaporation and dehydration of aqueous solution are mainly carried out at the boiling point of the solution, and it is difficult to operate the outlet gas temperature below 130 C. Although there is a clear gap between China and foreign countries, ...
In the current study, a total of seven esters were identified, and their concentrations are given in Additional file1: Table S2. Ethyl acetate, which is responsible for the fruity and pineapple flavors, was recorded. The highest concentration of ethyl acetate was found in enzyme soymilk yogurt ...
Ethyl acetate, as a small molecule containing only four carbon atoms, has a low boiling point. As a result, the new distilled liquor contains a large amount of ethyl acetate (232 mg/100 mL), which rapid decreases with aging for 2–3 years. The rapid decrease can be mainly associated ...
