Thermal Behavior of Lithium 4-Hydroxyisophthalates

Abstract

In previous papers, 4-hydroxyisophthalic acid (4-OIP) was found as an important intermediate in the Kolbe-Schmitt reaction. In this paper, the th ermal behavior of the lithium salts of 4-OIP has been examined together with lithium salicylates and p-hydroxybenzoates. The 4-OIP lithium salt decarboxylates mainly at the para-position to the hydroxyl group.
