摘要

In these experiments we evaluated the behavior of water and alcohols rate of evaporation by forced bubbling. Changing the quantity of nitrogen flux into the liquid or the temperature of the measure chamber, a freezer for cold temperatures or an oven for higher ones, it has been possible to analyze and compare the liquid mass evaporation rate with that calculated by Antoine Parameters formula. The results obtained are very similar to the theoretical ones except for Methanol that showed a 15% of higher evaporation rate. A special case is that of Decane, which Antoine Parameters graph presents a lack of values between forty and ninety degrees centigrade. The experiment showed an intermediate behavior between the two set of parameters.
