To better understand and ascertain the mechanisms of flotation reagent interaction with rare earth (RE) minerals, it is necessary to determine physical chemical properties constituent components. Seven oxides (CeO 2 , Er O 3 Nd Tm Yb La Tb 4 7 ) that cover elements (REEs) from light heavy REEs have been investigated using Raman spectroscopy. Multiple laser sources (wavelengths 325 nm, 442 514 632.8 nm) for shift ranges 100 cm −1 5000 these excitations were used each individual oxide. shifts...
Polyurethane binder systems based on hydroxyl-terminated polybutadiene (HTPB) possess several superior properties such as adhesion, high solid-loading capacity, outstanding mechanical performance, etc. They have been widely used in coatings and adhesives well medical military industries. The cure reaction between diisocyanates plays a key role the of final products adjustment process parameters. FT-IR spectroscopy is applied to investigate kinetics curing HTPB isophorone diisocyanate (IPDI)...
Abstract A polyoxometalate‐based ionic liquid‐doped sepiolite (SEP‐PIL) was prepared by electrostatically immobilizing phosphomolybdic acid (PMA) on natural embedded with imidazolium cations (SEP‐IL), and its structural properties were fully characterized various methods. Furthermore, a new intumescent flame‐retardant system (IFR) for high‐density polyethylene (HDPE) constructed adding SEP‐PIL into conventional HDPE/IFR composites. The retardant thermal decomposition behaviors...
A novel porous organic polymer pSt was prepared based on silica gel and used for the immobilization of NHPI. The obtained heterogeneous catalyst could adsorb toluene oxidize it to benzoic acid using a co-catalyst Co(OAc)<sub>2</sub> molecular oxygen.
Polyamine chelating adsorbents have a good removal effect on dye wastewater. In this study, small molecule triethylenetetramine and macromolecular poly(ethylene imine) were selected as aminated reagent, two kinds of chitosan microspheres, TETA-CTSms PEI-CTSms, obtained by emulsion cross-linking method. The microspheres fully characterized FTIR, SEM, XRD, EDS TGA. results showed that the N content PEI-CTSms increased significantly after reaction can reach 5.7 wt% 7.3 wt%, respectively....
Abstract Castor oil and its three derivatives including methyl ricinoleate, sodium ricinoleate ricinoleic acid were used as the raw material for alkali fusion to prepare sebacic acid. The reaction parameters catalyst, ratio of oleochemicals/NaOH, time temperature optimized. It was found that Pb 3 O 4 (1%) showed best catalytic performance, 553 K considered most suitable temperature. oleochemicals/NaOH ratios 15:14, 15:12 15:14 determined optimal castor oil, acid, respectively. In addition, 5...
A green and environmentally friendly route of no thinning agent was designed to prepare sebacic acid. Sodium ricinoleate selected as the raw material carry out solid-phase cleavage in a tubular furnace. The reaction parameters including catalyst, ratio sodium ricinoleate/KOH, time, temperature, absolute pressure were optimized obtain high yield satisfactory (70.2%) acid received presence 1% catalyst (Fe2O3) by weight (w/w), with 5:4 (w/w) ricinoleate/KOH at 543 K under 0.09 MPa 60 min....
Chloromethylated cross-linked polystyrene (CMCPS) microsphere is hydroxylated, obtaining hydroxylated (CPS-OH). Methacrylic acid (MAA) grafted on the surface of CPS-OH microspheres by cerium salt-hydroxyl group redox initiation system, graft-polymerization functional CPS-g-PMAA.

The Schiff base molecule of the title compound, C(14)H(12)N(4)O(6)·C(5)H(5)N, was obtained from condensation reaction 2-hy-droxy-3-meth-oxy-benzaldehyde and 2,4-dinitro-phenyl-hydrazine. C=N bond has a trans arrangement dihedral angle between two benzene rings is 3.49 (10)°. An intra-molecular N-H⋯O hydrogen generates an S(6) ring. In crystal, O-H⋯O bonds link mol-ecules.
The title compound, C(19)H(12)Br(2)ClN, was synthesized by N-alkyl-ation of 1-chloro-4-(chloro-meth-yl)benzene with 3,6-dibromo-9H-carbazole. carbazole ring system is essentially planar (mean deviation 0.028 Å) and makes a dihedral angle 74.6 (3)° the plane benzene ring.
