نویسندگان
چکیده
In this paper, a novel hydroxyl-containing quaternary ammonium surfactant N-(2-Hydroxyethyl)-N, N-dimethyl-3-[(1-oxododecyl)amino]-1-propanaminium (LPDC) was synthesized and introduced as collector for the reverse cationic flotation separation of apatite from quartz; adsorption mechanisms between LPDC two mineral surfaces were investigated by Fourier transform infrared spectrometer (FTIR), zeta potential measurements X-ray photoelectron spectroscopy (XPS) analysis. The micro-flotation tests showed that exhibited excellent performance. When pulp at natural pH concentration 25 mg/L, concentrate with P2O5 recovery 95.45% grade 38.94% could be obtained artificially mixed minerals. FTIR, potential, XPS analysis indicated onto quartz surface is stronger than surface; meanwhile, mainly provided electrostatic force hydrogen bonding.

In the title compound, C(18)H(24)NO(2) (+)·Cl(-), the absolute configuration of the new stereogenic centre (the C atom with a CH(2)OH substituent) was unambiguously determined to have an R configuration. The dihedral angle between the two aromatic rings is 30.82 (2)°. Inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds and intra-molecular N-H⋯O hydrogen bonds stabilize the crystal structure.

The title compound, C(19)H(21)NOS, is an inter-mediate for the synthesis of duloxetine hydro-chloride. In the mol-ecular structure, the thio-phene and naphthalene ring systems make a dihedral angle of 87.5°. All bond lengths and angles involving heteroatoms are as expected. In the crystal structure, no classical hydrogen bonds are found.
