or refluxer is needed the 16 hours into only once ?

It can be done in several sections, as long as the water level remains the same and does not fall too far from the original mark. Keep the reaction vessel sealed during all heating and cooling, and all should be cool.

SWIL usually does his reactions in this same way.
