Eight different Dichloro(bis{2-[1-(4-R-phenyl)-1H-1,2,3-triazol-4-yl-κN3]pyridine-κN})iron(II) compounds, 2–9, have been synthesised and characterised, where group R = CH3 (L2), OCH3 (L3), COOH (L4), F (L5), Cl (L6), CN (L7), H (L8) and CF3 (L9). The single crystal X-ray structure was determi...
1-(4-Bromophenyl)-5-phenyl-1H-1,2,3-triazole (BPT) was a newly synthesized compound. The acute toxicities of BPT to mice by intragastric administration have been determined and the result indicates that the intragastric administration of BPT did not produce any significant toxic effect on Kunmin...
The concentrations of monosaccharide anhydrides (levoglucosan, mannosan, galactosan), monocarboxylic acids (alkanoic acids C7 – C20 and two unsaturated fatty acids, palmitoleic and oleic acids) and organic and elemental carbon in PM1 aerosol samples were measured in two cities of the Czech Repu...
Support structures and materials are indispensable components in many Additive Manufacturing (AM) systems in order to fabricate complex 3D structures. For inkjet-based AM techniques (known as Material Jetting), there is a paucity of studies on specific inks for fabricating such support structure...
Benactyzine and drofenine are widely used anticholinergic drugs. Benactyzine is used to treat organophosphate poisoning and drofenine acts on smooth muscle to stop muscle spasms. Both of these drugs are esters. After they enter the bloodstream, they will interact with butyrylcholinesterase (BChE...
The chapter deals with a brief account of various topics in polyethylene terephthalate: blends, composites, and nanocomposites. This chapter discusses the different topics such as modification of polyethylene terephthalate, reinforcement of polyethylene terephthalate via addition of carbon-based...
The aliphatic-aromatic copolyester poly(butylene adipate-co-butylene terephthalate) (PBAT), also known as ecoflex, contains adipic acid, 1,4-butanediol and terephthalic acid and is proven to be compostable [1], [2], [3]). We describe here data for the synthesis and analysis of poly(butylene adip...
Di-2-ethylhexyl terephthalate (DEHTP), a structural isomer of the plasticizer di-2-ethylhexyl phthalate (DEHP), is used in food packaging and medical devices, among other applications, and is a potential replacement for DEHP and other ortho-phthalate plasticizers. Identifying sensitive and speci...
Development of ecofriendly biocomposites to replace non-biodegradable synthetic fibre composites for optimum performances is the main objective of this study. To highlight biocomposites as suitable replacements, polyethylene terephthalate matrix composites reinforced with blended water retted an...
The ever-increasing consumption of energy storage devices has pushed the scientific community to realize strategies toward organic electrodes with superior properties. This is owed to advantages such as economic viability and eco-friendliness. In this context, the family of conjugated dicarboxyl...
Owing to their toxicity, phthalate plasticizers are currently being replaced with terephthalates in many consumer products. Nevertheless, data on human exposure to and toxicity of terephthalates are still scarce. In this study, we developed a robust analytical method for the measurement of six t...
This paper appraised divergent chemical depolymerization routes for reprocessing chemically synthesis polyethylene terephthalate (PET) plastics bottle waste and offer resolutions to control the environmental complications emanating attributable to its utilize and disposal to the habitat. The con...
An engineered reversal of the β-oxidation cycle was exploited to demonstrate its utility for the synthesis of medium chain (6–10-carbons) ω-hydroxyacids and dicarboxylic acids from glycerol as the only carbon source. A redesigned β-oxidation reversal facilitated the production of medium chai...
Oscillaginin A, a novel chlorine-containing linear tetrapeptide, was isolated from the freshwater toxic cyanobacterium, Oscillatoria agardhii. The structure was elucidated by chemical degradation and 2D NMR analyses. Oscillaginin B, a dechlorinated derivative of oscillaginin A, was also isolated...
Ten new chiral cis-dioxidomolybdenum(VI) complexes with tridentate Schiff bases were synthesized by monocondensation of R(−)-2-amino-1-propanol with salicylaldehyde and its derivatives. Their spectroscopic properties have been investigated UV-Vis, CD, IR, one- (1H, 13C) and two-dimensional (COSY...
Three previously undescribed polyoxygenated cyclohexene derivatives named cherrevenol M (1), cherrevenol N (2), and cherrevenone (3), together with nine related known analogues 4–12 were isolated from the ethyl acetate fraction partitioned from the methanol extract of the aerial parts of Uvaria...
A new method for synthesizing compounds having benzothiazole and pyrazole moieties in their backbone has been successfully performed, based on the rearrangement of pyrazolylylidene-pyranopyrazolone in the presence of o-aminothiophenol in hot n-butanol. The new compound has been alkylated with di...
The synthesis of 1,4-dihydro-2-methyl- and 1,4-dihydro-1,2-dimethyl-4-oxo-nicotinic acids was accomplished following a route other than Ochiai's procedure, which yielded the isomer 1,6-dihydro-2-methyl-6-oxo-nicotinic acid ethyl ester, and not the 4-oxo-derivative, as reported. Analytical d...
The solubility of 2,4-dihydro-5-methyl-2-(4-methylphenyl)-3H-pyrazol-3-one in twelve organic solvents including methanol, ethanol, n-propanol, isopropanol, ethylbenzene, toluene, n-butanol, acetonitrile, ethyl acetate, 1,4-dioxane, cyclohexane and isopentanol were determined experimentally by us...
Reaction of chiral 2-[(tributylstannyl)methyl]propenamides with aldehydes proceeded with 1,6-asymmetric induction to give, after hydrolysis, α,-methylene-γ-butyrolactones in enantiomeric excesses as high as 80%.
