Unexpected formation of ammonium thiocyanate from the reaction of aqueous hydroxylamine with carbon disulfide

Role of carboxylates in the phase determination of metal sulfide nanoparticles

“…44 It is proposed that thiourea undergoes a transformation into ammonium thiocyanate around 170 1C and reacts with the carboxylic acid group of sodium oleate to form oleamide (Scheme 3). 44 Thiocyanate signals are also present in the NMR spectra and occur at around 7.0 ppm for 1 H NMR (NH 4 + ) and 130.7 ppm for 13 C NMR (SCN À ) 45 (Fig. S1, S2 and S11, ESI †).…”

Orthorhombic sulfur from Cap Garonne, Mine du Pradet

“…The structure of the low-temperature modification, α-S 8 was first determined in 1935 by Warren and Burwell [3] using crystals grown from CS 2 solution via rotation and oscillation film data. Subsequent studies focused on precise determinations of the lattice parameters, higher accuracy structure refinements, lattice thermal expansion experiments, analyses of thermal vibrations, charge density studies as well as high-pressure experiments up to the amorphization limit [4][5][6][7][8][9][10][11][12][13][14][15][16]. The early work has competently been summarized by Donohue [17], later in reviews on all sulfur modifications by Meyer [18] and Steudel and Eckert [19].…”
