Dimethyl carbonate has an ester- or alcohol-like odor, which is more favorable to users than most hydrocarbon solvents it replaces. Dimethyl carbonate has an evaporation rate of 3.22 (butyl acetate = 1.0), which slightly slower than MEK (3.8) and ethyl acetate (4.1), and faster than toluene (2.0) and isopropanol (1.7).
i.e. → Solvent added (clear) to compound (orange) to give compound solution (orange) → Vessel sealed but a small hole allows solvent vapour (clear) to slowly evaporate from compound solution (orange) over time to give crystals (orange) and a non-saturated solution (pale-orange).

K b, the ebullioscopic constant, which is dependent on the properties of the solvent. It can be calculated as K b = RT b 2 M/ΔH v, where R is the gas constant, and T b is the boiling temperature of the pure solvent [in K], M is the molar mass of the solvent, and ΔH v is the heat of vaporization per mole of the solvent.
Evaporation is the elimination of the solvent in form of vapor from a solution. For most evaporation systems, the solvent is water and the heat is provided by steam condensation. [ 4 ] In a forced circulation evaporation liquid is constantly circulated through the system.
Affects the traveling time of the polymer jet; should be high enough to allow complete evaporation of the solvent. Voltage, Feed rate: Feed rate: Determines the amount of solution available per unit of time. Influences the jet velocity and the material transfer rate. Increasing the rate causes more polymer to be processed at a given instant ...
It is useful as a solvent for its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether . The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide .
