In the procedure for Determining the Fragrances, it suggests that the organic layer dropped onto the watch glass should be given a little time for excess alcohol to evaporate so that when you examine the odor of the product, you are not confused by the odor of the alcohol. Why would the alcohol evaporate faster than your product?
