The solubility of D-xylose in formic acid and binary solvents of formic acid with formic acid and acetic acid, propionic acid, n-butyric acid or isobutyric acid was measured in the temperature range from 300.35 to 325.05 K using the synthetic method by a laser monitoring technique at atmospheric pressure. The solid-liquid equilibrium data will provide essential support for industrial design and further theoretical study. The experimental data show that the solubility of D-xylose in formic acid and in the mixtures of formic acid＋acetic acid （1︰1）, formic acid＋propionic acid （1︰1）, formic acid＋n-butyric acid （1︰1）, and formic acid＋isobutyric acid （1︰1） increases with temperature. The Apelblat equation, theλh model, and the ideal solution equation correlate the solubility data well.
