Fourier-transform infrared spectroscopy (FTIR) was successfully used for quantitative determination of diethylene glycol in glycerin raw material. In addition to the pure samples of both diethylene glycol and glycerin, nine binary mixtures of the two components with mixing ratios ranging from (70 to 98)%wt were created and studied as a training set. Glycerine showed, thereby, characteristic infrared bands at 1110, 992, 974, and 922?cm?1 while those of diethylene glycol appear at 1085, 887, and 881?cm?1. The quantitative determination of diethylene glycol in binary mixtures with glycerin was achieved upon using the absorbance difference between the 992?cm?1 and the 881?cm?1 as well as between 1110 and 1085?cm?1 bands. With an average %error of 0.60 and 1.74, respectively and a limit of detection down to 0.85%, the created calibration curves from the training set were applied successfully to determine the composition of another eight binary mixtures of the two materials representing a validation set. The method was also applied to aqueous solutions of diethylene glycol and glycerin that contains (25 and 50)%wt water. Once more, training and validation sets of mixtures with different diethylene glycol and glycerin ratios at the two water percentages were prepared and measured. Again, successful determination of diethylene glycol in these aqueous solutions was achieved with an average %error of 0.92 and 0.47, respectively. 相似文献

Abstract The crystallization and structures of a triclinic (henceforth T) (C6H9N2)2[CdBr4] and a monoclinic (henceforth M) of (C6H9N2)2[CoBr4] are reported. The crystal packing of both solids is analyzed and compared: both contain parallel chains of cations and stacks
of anions. In both T and M, each [MBr4]2− is hydrogen bonded non-symmetrically to surrounding cations in a ladder chains that run along b axis, with planar cations
in both structures falling in parallel to the planes to anions. In T the cation chains are further involved in classical π···π stacking, while in M the cation chains show less significant stacking, with longer repeat distance.
Index Abstract Extensive N–H···Br hydrogen bonds link both anions and cations into chains of the ladder type parallel to the crystallographic b axis.
