The solubility of sebacic acid in subcritical
water was investigated. Response surface methodology
was used to study the combined effects of the different
parameters such as temperature, static and dynamic time to
optimize the process conditions for the maximum solubility
of sebacic acid. Solubility results of sebacic acid were
observed to be highly correlated with quadratic model
according to analysis of variance. The solubility of sebacic
acid was found as 500 g L-1 in the optimum conditions at
400 K temperature, 4 min dynamic time and 28 min static
time. Approximation models were employed for determining solubility of sebacic acid at elevated temperatures.
