Are you sure you don't mean condensation?
I may be wrong, but I don't believe there is such a thing as condenseration. The only place I can find that word is in the paper, "Characterization of Ring-Opening polymerization of Genipin and PH-dependent cross-linking reactions between Chitosan and Genipin" by Fwu Long Mi.
That paper refers to Aldol Condenseration, however since Aldol Condensation is an actual scientific process I am assuming that the author has simply misspelled the word.
If you do mean condensation, then it is the process of a gas turning into a liquid and the opposite of evaporation.
