Abstract
X-ray diffraction of glycerol mono (12-hydroxystearoyl) glycerol borate (GHSGB) was measured and its two crystal forms were found.
GHSGB from the melt (α-form) had a single strong short spacing line at 4.16Å, and the one from solvent crystallization (β-form) had three strong short spacing lines at 4.00, 4.17 and 4.53Å.
Long spacings of α- and β-form were observed at 73Å and 70Å, respectively.
DSC and IR spectra data of GHSGB were discussed in addition to those X-ray analyses.
