WebJul 1, 2013 · If your mixture reached 160 degrees C then you must have boiled off all the water. If there was some water left, it would stay at around 100 degrees C and all (most of) the heat would be used to evaporate water. The boiling point of glycerol is about 290 degrees C and so you didn't boil that off. WebGlycerol is completely miscible with water. When exposed to moist air, it absorbs water (hydroscopic) as well as gasses such as hydrogen sulfide and sulfur dioxide.
