X-ray diffraction patterns have been obtained for the lyotropic phases ofn-octyl 1-O-β-d-glucopyranoside and the relatedn-heptyl,n-nonyl andn-decyl compounds with water. The octyl compound exhibits all three liquid crystal phases and forms a micellar solution with increasing solvation, when the crystal come into contact with water at room temperature. The X-ray diffraction patterns show a one-dimensional lamellar phase with <dx> = 28.4 Å, a three-dimensional face-centered cubic phase with <a> = 51.2 Å, and a two-dimensional hexagonal phase with <a> = <b>= 36.7 Å. The micellar solution has a distribution pattern with a maximum at <dx> = 33.8 Å. Crystals of the heptyl, nonyl and decyl derivatives form only the lamellar phases and the micellar solution on contact with water at room temperature.
