Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1120-02-1, molcular formula is C21H46BrN, introducing its new discovery. category: catalyst-ligand
New mesostructured bisalkyltrimethylammonium dichromates of formula (CnH2n+1(CH3)3N)2Cr 2O7·xH2O (n=12, 14, 16, 18; 0?x?2) were prepared at 80C from an aqueous solution of alkyltrimethylammonium salt and K2Cr2O7. The chemical composition and phase transitions have been determined by thermogravimetric analysis (TGA) coupled with differential scanning calorimetry (DSC) and mass spectrometry (MS). As suggested by X-ray diffraction and transmission electron microscopy studies, the lamellar hydrated and anhydrous bisalkyltrimethylammonium dichromates crystallize in the triclinic system, with space groupP-1. The structure of the anhydrous bisoctyltrimethylammonium dichromate, (C18H37(CH3)3N)2Cr 2O7, was determined from single-crystal X-ray diffraction data. The compound crystallizes in the triclinic system, space groupP-1, with 2 formula units in a cella=7.197(1) A,b=8.816(2) A,c=43.400(9) A,alpha=93.43(3),beta=90.00(3),gamma=113.98(3). The structure consists of discrete dichromate anions stacking up in a layer, separated by a double layer of octyltrimethylammonium surfactant chains lying in parallel. The interlayer spacing of 43.4 A, smaller than the expected value for the fully extended molecular model, is achieved through a tilting of the surfactant chains of about 37.5 from the normal to the (Cr2O7)2-plane.
