Octyl methacrylate

Water solubility

Link to relevant study record(s)

Reference

Endpoint:

water solubility

Type of information:

(Q)SAR

Remarks:

Water solubility was measured experimentally for a series of alkyl-methacrylate esters from Methyl methacrylate to Decyl methacrylate. Molecular volume plotted against water solubility (on a log10scale)

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Justification for type of information:

Water solubility was measured experimentally for a series of alkyl-methacrylate esters from Methyl methacrylate to Decyl methacrylate. The water solubility of alkyl-methacrylate esters decreses with increasing alkyl-chain length. Methyl methacrylate is the most soluble ester in water (measured 15.3 g/kg) at 20 °C. 2-Ethylhexyl methacrylate was the largest ester whose solubility was measured experimentally (lowest solubility with a value of 0.0078 g/kg at 20°C).
The water solubility of the alkyl-methacrylate esters decreses exponentially when plotted against molecular volume. The water solubility of both straight and branched chained members of the series showed a direct dependance on molecular volume. Molecular volume plotted against water solubility (on a log10scale) was linear. Threfore the water solubility was estimated by the linear regression analysis of data for those esters whose solubility was measured experimentally.

Qualifier:
