Crystal structure of anhydrous d-D-mannitol

چکیده
The crystal structure of anhydrous d-D-mannitol (C6H14O6) was solved from high-resolution synchrotron X-ray powder diffraction data collected on a mixture containing 20% and 80% w/w of band d-D-mannitol, respectively. The direct space simulated annealing program PSSP, and Rietveld analysis employing GSAS were used to determine and refine the structure. The polymorph has monoclinic symmetry, space group P21 with a55.089 41(5) Å, b518.2504(2) Å, c 54.917 02(5) Å, and b5118.303(2)°. There is one molecule in the irreducible volume of the unit cell. The pattern of hydrogen bonding is significantly different than the previously known a and b forms. © 2003 International Centre for Diffraction Data. @DOI: 10.1154/1.1582460#

Controlling the physical form of mannitol in freeze-dried systems.
A potential drawback with the use of mannitol as a bulking agent is its existence as mannitol hemihydrate (MHH; C₆H₁₄O₆·0.5H₂O) in the lyophile. Once formed during freeze-drying, MHH dehydration may require secondary drying under aggressive conditions which can be detrimental to the stability of thermolabile components. If MHH is retained in the lyophile, the water released by MHH dehydration d...
متن کاملKinetic, mechanistic and thermodynamic investigations on Iridium (III) catalyzed oxidation of D-Mannitol by N-chloro-p-toluenesulfonamide in perchloric acid medium
The present paper deals with the kinetics and mechanism of homogeneously Ir(III) chloride catalyzed oxidation of D-mannitol by chloramine-T [CAT] in perchloric acid medium in the temperature range of 30 to 45 0C. The reaction is carried out in the presence of mercuric acetate as a scavenger for chloride ion. The experimental results show first order kinetics with respect to the oxidant [CAT] an...
متن کاملMeasurement and calculation of second - harmonic generation in single - crystal spheres : application to d coefficients of D - mannitol , C 6 H 14 O 6
The measurement of d coefficients from second-harmonic efficiencies in crystal spheres is studied. KH2PO4 is used as a reference for measurements in spheres and with the Maker-fringes technique. As an example, unknown d coefficients in an orthorhombic mannitol, C6H14O6, in which large coefficients of optical rotation have recently been measured, are determined as d123 = 0.06(2) pm V −1 and comp...
متن کاملSurfactant-facilitated crystallization of dihydrate carbamazepine during dissolution of anhydrous polymorph.
The influence of two structurally different anionic surfactants on the anhydrous-to-dihydrate transformation of carbamazepine (CBZ) was investigated. The surfactants studied were sodium lauryl sulfate (SLS), a surfactant commonly used in compendial dissolution methods, and sodium taurocholate (STC), an important surfactant in the solubilization and absorption of drugs and lipids in the gastroin...
