Objective/Description:
Hydroxybenzoic acids and related compounds are pharmaceutically important
substances. In particular, 2-hydroxybenzoic acid has been widely used
as a medicine and a preservative for food products; 4-hydroxybenzoic
acid alkyl esters have also been used as preservatives for food. The
relation between the use of these substances and human health requires
evaluation of the solubilities of 2-, 3-, and 4-monohydroxybenzoic acids
and of 4-hydroxybenzoic acid alkyl esters in water, organic and mixed
solvents. It is also suggested to evaluate the solubilities of: (a)
2- and 3-hydroxybenzoic acid in supercritical carbon dioxide containing
organic solvents such as methanol and acetone; (b) monohydroxybenzoates,
2,3-, 2,4-, 2,5-, 2,6-, 3,4- and 3,5- dihydroxybenzoic acid salts of
alkali, transition and rare earth metals in water and organic solvents.
Progress:
All of the solubility data of hydroxyl benzoic acids and hydroxybenzoates
have been compiled. A total of 177 original studies treating ternary
systems published from 1898 to 2001 has been carried out. The solubilities
of hydroxyl benzoic acids and alkyl p hydroxybenzoates in water and
in various alcohols could be statistically evaluated at various temperatures.
