Improper well casings and produced water handling can lead to hydraulic fracturing fluid migration and groundwater pollution. Interactions among the chemical components can cause compositional changes in hydraulic fracturing fluids. This study focuses on degradation or transformations of 3-furfuraldehyde (or furfural) by activated-persulfate oxidation, two chemicals reported in hydraulic fracturing additives. As hydraulic fracturing conditions may be conducive to persulfate activation, the degradation of furfural was examined using elevated temperatures, varying persulfate dosing and Fe (III) concentration, initial pH, and the presence of other chemical additives (e.g., a gelling agent and an enzyme breaking agent). Experiments showed furfural degradation using activated persulfate followed pseudo-first order kinetics with respect to the furfural concentration. Impacts of pH and ferric sulfate concentrations were investigated at different temperatures and the results were fit to the Arrhenius model to establish the activation energy. Decreasing the pH to 2.54 caused an increase in the furfural removal. The addition of ferric sulfate to solutions with pH 5.4 had no impact on the activation energy of furfural oxidation, which was 107 kJ mol?1, while decreasing the pH to 2.54 allowed for the activation energy to decrease to 75 kJ mol?1. Quenching with methanol and tert-butyl alcohol indicated significant hydroxyl radical contributions to furfural degradation compared to sulfate radicals during thermal persulfate activation in the presence of iron and acidic conditions. Furthermore, furfural degradation was monitored in the presence of other hydraulic fracturing chemical additives establishing furfural degradation does not occur as rapidly. However, furfural does still degrade in this matrix and this indicates that persulfate may break down other chemicals in hydraulic fracturing fluids more preferentially than the target gelling agent.

A series of N2-[(acylamino)alkyl]-6,7-dimethoxy-2,4-quinazolinediamines was synthesized as potential alpha1-adrenoceptor antagonists. When administered to spontaneously hypertensive rats at 10 mg/kg po, a number of propanediamine derivatives showed good antihypertensive activity, whereas the ethanediamine derivatives, albeit being structurally more closely related to prazosin, were devoid of this property. The most active derivative, N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro- 2-furancarboxamide hydrochloride, alfuzosin, showed high selectivity for peripheral alpha1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the light of these results, alfuzosin was selected for clinical evaluation.

Microorganisms are found everywhere, and they are closely associated with plants. Because the establishment of any plant-microbe association involves chemical communication, understanding crosstalk processes is fundamental to defining the type of relationship. Although several metabolites from plants and microbes have been fully characterized, their roles in the chemical interplay between these partners are not well understood in most cases, and they require further investigation. In this review, we describe different plant-microbe associations from colonization to microbial establishment processes in plants along with future prospects, including agricultural benefits.

Commercially available N-Boc-4-O-benzyl-L-homoserine was treated with trifluoroacetic acid and the corresponding, N-deprotected derivative was submitted to deamination to give 4-O-benzyl-3-deoxy-L-glycero-tetronic acid (5). In another approach to 3-deoxy-L-glycero-tetronic acid protected at position 4, the carboxylic groups in L-malic acid were reduced, and the resulting triol was benzylidenated. Oxidation of the 2,4-O-benzylidene derivative formed with CrO3-pyridine complex in the presence of t-butyl alcohol gave t-butyl 2,4-O-benzylidene-3-deoxy-L-glycero-tetronate (13). The latter was saponified with aqueous sodium hydroxide to give, after Na+ exchange for H+, 2,4-O-benzylidene-3-deoxy-L-glycero-tetronic acid (15). Opening of the acetal ring in 13, followed by hydrolytic cleavage of the t-butyl ester function gave material indistinguishable from 5 obtained in the original way. When tested for their efficiency of N-acylation of derivatives of D-perosamine, both acids 5 and 15 gave the corresponding tetronamido derivatives in high yields.

Lignocellulosic biomass can be converted to significant platform molecule 5-hydroxymethylfurfural (HMF), from which one can envision a number of biofuels and chemicals through either chemical or biological conversions. Chemoselective hydrogenation is one of the important pathways for the upgrading of HMF into furanyl diols consisting of 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF). BHMF and BHMTHF are all-purpose intermediates for the manufacture of chemicals, fuels, and functional materials. In this context, we comprehensively summarized the studies on the chemoselective hydrogenation of HMF into furanyl diols in terms of different H-donors, including molecular H2, alcohols, formic acid, and other alternative H-donors. Through the systematic survey of the previous works, a feasible research direction is discussed for the production of furanyl diols.
