The test phenomena and results
1) The result of the preliminary test has
proved that the water solubility is between 1g/L and 10 g/L; the test
method can then be desiged as following: 2.5 g of the sample should be
taken and 100 mL of water be used.
2) The centrifuging solutions should be
diluted for 2.5 - 25 times based on the fact that the concentrations of
the standard solutions are 0.02 g/50 mL. The actual procedure is as
pipette 2.00 mL of each centrifuging
solution into each 10 mL volumetric flask, fill to the mark with
methanol and mix well. Diluting times can be obtained: n = 5.
The result of Water Solubility
Relative deviations (absolute value) between
each two results of the centrifuging solutions:
1#-2#: 3.2%; 1#-3#: 3.6%; 2#-3#: 0.4%
Discuss and evaluation of analytical
The determination results can be avail based
on the fact that each deviation is less than 15%.
The average value of three results can be
calculated as the final data of Water Solubility:
Very well documented study according to OECD
water solubility of α,α,α',α'-tetramethyl-m-xylene-α,α'-diol is 2.66 g/L
at 20°C and pH 6.
The water solubility of α,α,α',α'-tetramethyl-m-xylene-α,α'-diol is 2.66
g/L at 20°C and pH 6.
