Key result
Water solubility:
58.3 g/L
Temp.:
20 °C
pH:
> 3.6 - < 3.8
Remarks on result:
other: Value as average with n=6.
Details on results:
The substance in the test solution was hydrolysed to form hydrolysate containing acetic acid (acetic acid concentration in test solution = 125~232 mg/L). The other hydrolysate was detected on GC chromatograms to contain 3-methoxy-3-methylbutanol.
Though same impurities were present in the sample, it was confirmed the dissolution more than acetic acid formation rate (3-methoxy-3-methylbutanol concentration in test solution = 630~886 mg/L). Hence, it was concluded that this test of measurement were performed in the hydrolysis condition.

 Sample name   Solubility (g/L)   Maximum Difference%   pH 
 Measured   Average   Standard Deviation 
 Sample 1-a   57.7   58.3   0.467   2.06   3.8 
 Sample 1-b   58.0   3.8 
 Sample 2-a   58.0   3.7 
 Sample 2-b   58.1   3.6 
 Sample 3-a   59.0   3.6 
 Sample 3-b   58.7   3.6 
Conclusions:
The solubility in water of MMB-Ac is 58.3 g/L at the temperature of 20+/-0.5°C by the flask method (the value measured in the hydrolysis condition of the substance).
