Any other information on results incl. tables

Measurements:



Visual determination of water solubility :
------------------------------------------------------
To 20 ml of water, 3-methyl-l-pentin-3-ol was added until turbidity occurred.
Consumption of 3-methyl-l-pentin-3-ol : 2.7 ml
This results in a water solubility of
103.0 g in 1 1 total solution


 


Determination of the concentration of 3-methyl-l-pentin-3-ol in the water solution saturated at 25 °C by GC.
------------------------------------------------------------------------------------------------------------------------------------------------
c (3-methyl-l-pentin-3-ol)
1 . Measurement: 101.8 g/ l
2 . Measurement: 100.9 g/l
3 . Measurement: 99.8 g/l
4 . Measurement: 99.8 g/l
5 . Measurement: 99.1 g/l
6 . Measurement: 101.3 g/l
Average:                 100 .4 g/l
Standard deviation 1 .0

The mean value of the two methods of determination is: 102 g in 1 l total solution
