Green polymeric surface active agents for crude oil demulsification

The present work aims to develop a class of green demulsifiers for effective demulsification process. In this respect, six chitosan-based nonionic surfactants were prepared by chemical modification of chitosan with two aliphatic fatty acids, namely, lauric and stearic. The products were then reacted with polyethylene glycol (PEG 400, 1000 and 2000 g/mol) to produce ether amides surfactants. The prepared surfactants were characterized by IR spectroscopy and their thermal properties were investigated. It was found that the thermal stability of the prepared surfactants increase by increasing the length of PEG chain. Surface properties of the prepared surfactants were calculated through surface tension measurements at different temperatures. Furthermore, the demulsification efficiency of the prepared surfactants was verified under different conditions. Also, maximum water separation was achieved at 45 degrees C, neutral medium and low salt concentration. Viscosity of crude oil before and after demulsification was used as a parameter for demulsification process. Moreover, the demulsification process achieved by the green demulsifiers was monitored by the optical microscope. (C) 2018 Elsevier B.V. All rights reserved.

8-Aminoquinoline-Assisted Synthesis and Crystal Structure Studies of Ferrocenyl Aryl Sulfones

A copper-catalyzed 8-aminoquinoline-directed oxidative cross-coupling of the C-H bond of ferrocene with sodium arylsulfinates has been achieved. The robust copper catalyst tolerates a range of methyl, tert-butyl, bromo, chloro, iodo and nitro functional groups in the phenyl ring, and set the stage for the synthesis of substituted ferrocene sulfones. Furthermore, X-ray crystal structure study on several ferrocenyl sulfones reveals the tetrahedral geometry around sulfur; interestingly, the O-S-O angle is larger than the electropositive substituent C-S-C angle which could be explained by Bent’s rule. Further, unusual intramolecular O(S)…N(amide) short contacts (2.925-3) and O(S)…C=O were also noticed in ferrocenyl sulfones.

A theoretical and NMR lanthanide-induced shift (LIS) investigation of the conformations of lactams.

Molecular mechanics (MM) with MMFF94 and MMX force fields and ab initio (RHF/6-31G*,RHF/6-311G**, and B3LYP/6-311G**) calculations are used with lanthanide-induced shift (LIS) to investigate the conformations of N-methyl-2-pyrrolidone 1, N-methyl-2-piperidone 2, epsilon-caprolactam 3, -valerolactam (1,5-dimethyl-2-pyrrolidone) 4, 2-azetidinone 5, 4-methyl azetidinone 6, 4-phenyl azetidinone 7, and N-methyl-4-phenyl azetidinone 8. The Yb(fod)(3) paramagnetic induced shifts of all the H-1 and C-13 nuclei are measured and the corresponding diamagnetic complexation shifts obtained by the addition of Lu(fod)(3). The complexation model (two-, three-, or four-site) used depends on the relative rates of the processes involved. The amide inversion is the same order as that of the 5- and 6-membered lactam rings and much faster than the lanthanide complexation and the inversion of the 7-membered ring. Both MM and ab initio calculations give an envelope conformation for 1 with C-4 out of the ring plane in agreement with the LIS analysis. For the piperidone ring of 2, the half-chair is calculated as the most stable form. The LIS analysis confirms this but cannot exclude a small amount (<2%) of the boat conformation. For 3, the LIS analysis gives a minimum for 90:10% chair to boat conformation, and 4 exists in two envelope conformations with the C-5-Me ps-eq and ps-ax in an eq/ax ratio of 94:6%. In 2-azetidinone 5, the ab initio calculations gave both ring and nitrogen planar, but the MMFF94 calculations give a butterfly ring and pyramidal nitrogen. The LIS analysis for 5 gave good agreement (Rcryst 0.46%) for the MMFF94 geometry with endo NH but the planar ab initio geometries worse agreement (Rcryst=1.1%). For 4-methyl-2-azetidinone 6, the MMFF94 geometry gave good agreement (Rcryst 0.96%) with two butterfly conformations with axial and equatorial methyl groups in 1:1 ratio. All the planar geometries gave worse agreement (Rcryst >1.5%). In 4-phenyl azetidinone 7, the MMFF94 geometry with 60% of the axial conformer gave Rcryst 1.2% but the other geometries Rcryst >1.5%. In contrast the N-methyl-4-phenyl-2-azetidinone 8 gave good agreement for all the geometries. The butterfly conformation gave Rcryst 1.1% for 80% of the axial conformer and the planar geometries Rcryst 0.98%. The LIS results confirm the ab initio and MM optimised geometries, but the conformer energies at times differ from the calculated values. They also differ considerably from the corresponding values for the lactones studied previously, and possible reasons for this are discussed.

Elucidating the pyrolysis reaction mechanism of Calotropis procera and analysis of pyrolysis products to evaluate its potential for bioenergy and chemicals

The present study was focused on evaluating the bioenergy potential of waste biomass of desert plant Calotropis procera. The biomass was pyrolyzed at four heating rates including 10 degrees Cmin(-1), 20 degrees Cmin(-1), 40 degrees Cmin(-1), and 80 degrees Cmin(-1). The pyrolysis reaction kinetics and thermodynamics parameters were assessed using isoconversional models namely Kissenger-Akahira-Sunose, Flynn-Wall-Ozawa, and Starink. Major pyrolysis reaction occurred between 200 and 450 degrees C at the conversion points (alpha) ranging from 0.2 to 0.6 while their corresponding reaction parameters including activation energy, enthalpy change, Gibb’s free energy and pre-exponential factors were ranged from 165 to 207 kJ mol(-1), 169-200 kJ mol(-1), 90-42 kJ mol(-1), and 10(18)-10(26) s(-1), respectively. The narrow range of pre-exponential factors indicated a uniform pyrolysis, while lower differences between enthalpy change and activation energies indicated that reactions were thermodynamically favorable. The evolved gases were dominated by propanoic acid, 3-hydroxy-, hydrazide, hydrazinecarboxamide and carbohydrazide followed by amines/amides, alcohols, acids, aldehydes/ketones, and esters.

Effect of aromatic core on the supramolecular chirality of L-phenylalanine derived assemblies

Constructing chiral supramolecular assemblies with controllable handedness has attracted much attention in materials science, biology and chemistry, owing to their outstanding photophysical properties and novel biological effects. Herein, four gelators derived from L-phenylalanine were synthesized and their gel formation and self-assembled nanostructures were investigated. It was found that the handedness, helical pitch and diameter of these self-assemblies were successfully controlled by tuning the structure of central aromatic groups. Left- and right-handed nanofibers with different dimensions were obtained, showing configuration-regulated assembly behavior. These self-assemblies were further characterized by CD, FTIR, SEM, and UV-vis, and the results suggested that the pi-pi stacking among the central aromatic rings and hydrogen bonds among the amide groups at the terminals play important roles in the formation of these self-assemblies.

Synthesis of tri(di)fluoroethylanilines via copper-catalyzed coupling reaction of tri(di)fluoroethylamine with (hetero)aromatic bromides

We have realized the first Ullmann type coupling reaction of tri(di)fluoroethylamine with (hetero)aromatic bromides, employing 5-20 mol% Cu2O and an oxalamide ligand [N-(2,4,6-trimethoxyphenyl)acetamide]. This efficient and practical method has the following features: (i) avoids the use of an expensive catalyst; (ii) does not require anhydrous solvent and strict air extrusion; (iii) uses bench stable and inexpensive (hetero)aromatic bromides; (iv) is suitable for the synthesis of fluoroalkylated hetero-aromatic substrates; (v) is suitable for gram-scale synthesis. This work also shows the negative fluorine effect for the alkylamines in the copper catalysed coupling reactions.

One-step phosphorylated poly(amide-amine) dendrimer loaded with apigenin for simultaneous remineralization and antibacterial of dentine

Dental caries, starting from demineralization of enamel and dentine, is closely related with acid-producing bacteria in oral cavity, for example, Streptococcus mutans. Remineralization is an efficient way to prevent the disease progression and facilitate the therapy of incipient caries. Therefore, for the purpose of effective dentine repair, remineralization and antibacterial should be combined simultaneously. However, most of the literatures only focus on one single aspect, while combing remineralization and antibacteria for dentine repair in one system is rarely reported. Here in this work, phosphoryl-terminated poly(amide-amine) dendrimers were loaded with apigenin, a water-nonsoluble drug antibacterial agains Streptococcus mutans. The apigenin-loaded dendrimers bind strongly with dentine, which further induce dentine tubules occlusion through mineralization in artificial saliva, and the release of apigenin can prevent further erosion of dentine by bacteria. Meanwhile, the phosphorylated dendrimers are easily prepared by one-step modification of poly(amide-amine) and exhibit good cytocompatibility. This strategy developed here can provide reference for the design of effective anti-caries materials.
