Abstract:

The title compound, Rb2[Co(H2O)6](C8H5O4)4·4H2O, consists of nearly regular octahedral [Co(H2O)6]2+cations with the CoIIcations on the inversion centre (special position 2a), Rb+cations, hydrogen phthalate (Hpht−) anions and disordered water molecules. The Rb+cation is surrounded by nine O atoms from Hpht−anions and water molecules, with a strongly deformed pentagonal–bipyramidal geometry and one apex split into three positions. The crystal packing is governed by numerous hydrogen bonds involving all water molecules and Hpht−anions. In this way, layers parallel to theabplane are formed, with t

Abstract:

The structure of the title compound, C23H27N2O4 +·C8H3Cl2O4 −, a 1:1 proton-transfer compound of brucine with 4,5-dichlorophthalic acid, has been determined at 130 K. The brucinium cations and the hydrogen phthalate anions associate through single N—H...Ocarboxylate hydrogen bonds [2.639 (3) Å], giving dimers which are extended via weak head-to-tail C—H...Omethoxy associations into chains forming down the 21 screw axis of the unit cell. The carboxyl proton of the anion gives a short intramolecular O—H...Ocarboxylate hydrogen bond [2.441 (3) Å].

The research presented here describes the development of membranes made of polymeric materials with unique cobalt(II) complexes to identify nitrate anions in water.

Good nitrate specificity was accomplished by incorporating these Co(II) complexes onto membranes alongside the plasticizer dibutyl phthalate (DBP).

Largest decreases in electrophoretic mobility were observed for iodide, perchlorate, and thiocyanate, probably due to inclusion of these anions in the cyclodextrin (CD) cavity.

Three coordination polymers—{[Ag2(SIP)(4-pp)]·[Ag(4-pp)2]·H2O}n, [Pb4(SIP)2( μ3-OH)2(H2O)2]n, and {[Zn2(SIP)2(4-pp)4][Zn(4-pp)2(H2O)4]·4H2O}n (SIP = 5-sulfoisophthalic acid anion, 4-pp = 4-phenylpyridine)—are constructed under hydrothermal or solvothermal conditions using sodium m-phthalate 5-sulfonate (NaH2SIP) and 4-phenylpyridine as ligands. The structures of the three complexes are determined by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analyses, Fourier-transform infrared analysis, and photoluminescence.

Abstract:

A polymer inclusion membrane (PIM) composed of 50 wt% base polymer poly(vinylidenefluoride-co-hexafluoropropylene), 40 wt% extractant Aliquat® 336, and 10 wt% dibutyl phthalate as plasticizer/modifier provided the efficient extraction of vanadium(V) (initial concentration 50 mg L−1) from 0.1 M sulfate solutions (pH 2.5). The average mass and thickness of the PIMs (diameter 3.5 cm) were 0.057 g and 46 μm, respectively. It was suggested that V(V) was extracted as VO2SO4− via an anion exchange mechanism. The maximum PIM capacity was estimated to be ~56 mg of V(V)/g for the PIM. Quantitative back-

Abstract:

As new emerging pollutants, phthalic acid monoesters (PAMs) pose potential ecological and human health risks. In the present study, adsorption performance of monobutyl phthalate (MBP) onto two macroporous base anion-exchange resins (D-201 and D-301) was discussed. It was found that the adsorption isotherms were best fitted by the Langmuir equation while the adsorption kinetics were well described by pseudo-first-order model. Analyses of sorption isotherms and thermodynamics proved that the adsorption mechanisms for DBP onto D-201 were ion exchange. However, the obtained enthalpy values indicat

Abstract:

The chemical components from superheated water extractive of fresh Phyllostachys heterocycla shavings were separated and identified by GC/MS after enriched. Relative content of each component was determined by area normalization. 31 compounds representing 99.99% of the extractives were identified. The main and abundant constituents were as: heptacosane (35.37%), 2,2,4-trimethyl-3- (3,8,12,16-tetramethyl-heptadeca-3,7,11,15-tetraenyl)-cyclohexanol (16.25%), isochiapin B (12.24%), tetradecane, 2,6,10-trimethyl- (cas) (7.59%), dibutyl phthalate (5.66%), etratriacontane (cas) (4.89%), 1,2-benzened

Abstract:

Potassium phthalide-3-carboxylate (3-oxo-1,3-dihydroisobenzofuran-1- carboxylate ) decarboxylates readily in dimethyl sulfoxide at 145°, and the intermediate phthalidyl anion is efficiently trapped by α,β - unsaturated ketones. The major 1,4-addition product is accompanied by smaller amounts of an isomeric product formed by subsequent cyclization and rearrangement, and sometimes traces of a 1 : 2 1,4-addition product. The caesium salt gives slightly more cyclized product, and the lithium salt undergoes very slow decarboxylation. The synthetic usefulness of the salt decarboxylation is compared

The article is devoted to the development of an ionometric sensor for the determination of hexamethylenetetramine (HMTA). It was found that poorly soluble complex compounds with the composition (HMTA)3(PMo12O40)2 and (HMTA)3(PW12O40)2 are formed as a result of the interaction of the cation of the test substance with the anions of heteropoly acids. The obtained compounds were used as electrode active substances for polyvinyl chloride membranes of ionometric sensors. Phthalic acid derivatives (dibutyl and dioctyl phthalates) were used as solvents for plasticized membranes. The optimal compositio

Dibutyl phthalate as porogen forms an asymmetrically porous structure of membranes along thickness direction. One side of the membranes has a dense skin layer surface with 1.5–15 μm and the other side of the membranes has a porous one.

Abstract:

Phthalate acid esters (PAEs) are the most frequently utilized synthetic chemical compounds worldwide. They are typical emergent contaminants and are currently attracting considerable concern due to their risks to plants, animals, and public health. Determining the vital environmental factors that affect the toxicity of target pollutants in soil is important for vegetable production and the maintenance and control of soil productivity. We investigated the influence of di-n-butyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) under different soil conditions on physiological changes in wa

Abstract:

Polyoxyethylated sorbitans (polysorbates) are widely used in the chemical, pharmaceutical, and cosmetic industries, but only quantitative determination is used mainly for chromatographic methods. In this paper, the results of the development and testing of a potentiometric sensor sensitive to nonionic surfactant polyoxyethylene sorbitan monolaurate (polysorbate-20) are presented. An anion of the heterogeneous acid of the Keggin structure (12-molybdophosphate heteropolyacid) was used as a counterion to obtain the electrode-active substance for the potentiometric sensor membrane.
