Bio-resourced non-isocyanate polyurethane (NIPU) network was synthesized to valorize a sustainable natural product (i.e., tannic acid, TA) toward biomaterials. Thus, a glycerol-based epichlorohydrin was glycidylated to form epoxidized TA (ETA). Facile chemical fixation of CO2 onto ETA was used t...

Mucor miehei lipase (Mm-L) covalently bind on a hexagonally ordered silica SBA-15 (Santa Barbara Amorphous), previously functionalized with isocyanate moieties, was examined as biocatalyst for transesterification of colza oil with methanol. The isocyanate-mesoporous silica (NCO-SBA-15) was obtai...

Epoxy networks present good adhesion properties but are brittle in nature due to the high crosslink degree. The modification with silica particles and rubber can be a useful approach for improving adhesion properties without affecting the thermal properties and stiffness. This work present a new...

The study concentrates on the syntheses of modified 2-hydroxynicotinic acid by 3-(triethoxysilyl)-propyl isocyanate (TESPIC) and the preparation of their corresponding organic-inorganic molecular-based hybrid material with the two components equipped with covalent bonds. The bridging unit is a d...

A bifunctional reagent of 3-(triethoxysilyl)propyl isocyanate (TEPI) was initially adopted as a spacer reagent to prepare the bonded types of chiral stationary phases (CSPs) with cellulose derivatives. The silica-based CSPs were chemically prepared with non-regioselective and regioselective appr...

Isocyanate-based polyimide foams (PIFs) with different dosages of liquid tri (1-chloro-2-propyl) phosphate (TCPP) and micro-sized hydrotalcites (LDHs) particles alone, as well as different mixing ratios of TCPP and LDHs, were prepared via a one-step process in this work. Limiting oxygen index (L...

In the present study, graphene oxide (GO) nanosheets were synthesized and then functionalized with 3-(triethoxysilyl)propyl isocyanate (TEPIC) reactive precursor to study the effect of surface functionality of GO on the mechanical and anti-corrosion properties of polyurethane (PU) based coatings...

A dual role of hydrogen sulfide (H2S) in inflammation is well-reported and recent studies demonstrated adipogenic effects of H2S in 3T3-L1 cells. Here, we aimed to investigate the effects of H2S on adipocyte differentiation and inflammation. H2S concentration in 3T3-L1 culture media was increase...

A simple, fast, sensitive and robust method for the determination of the sulfur mustard (SM) exposure biomarker–N7-[2-[(2-hydroxyethyl)thio]-ethyl]guanine (HETEG) was reported using high-performance liquid chromatography–positive electrospray tandem mass spectrometry (HPLC–ESI-MS/MS), working...

Previous work shows that X Faujasite zeolite in a dried condition exhibits nucleophilic character in which the nucleophilic supercage oxygens are not appreciably hydrogen bonded to water and in which the leaving anion-assisting cations are not appreciably coordinated by water. Dry X Faujasite ze...

In addition to ethanolamine and propanolamine it was found that 2-ethoxyethylamine is a substrate for the corrin-dependent enzyme ethanolamine-ammonia lyase. The enzyme has the same V for 2-ethoxyethylamine as ethanolamine, but the Km for this substrate is 4.3 · 10−3 M. Acetaldehyde and ethylam...

A simple and efficient procedure for the preparation of silica-bonded N-propyl sulfamic acid (SBNPSA) by the reaction of 3-aminopropylsilica (1) and chlorosulfonic acid in chloroform is described. This solid acid is employed as a new catalyst for the formylation of alcohols and amines with ethyl...

Cl(2P3/2) atoms were produced by photolysis of Cl2 at 351 nm in the presence of alkyl formates and monitored by LIF spectroscopy at 134.72 nm. Rate coefficients of k(Cl + C2H5OC(O)H) = (9.5 ± 0.3)×10−12, k(Cl + n-C3H7OC(O)H) = (4.5 ± 0.3) × 10−11 and k(Cl + n-C4H9OC(O)H) = (1.2 ± 0.1) × 10...

Using the TiCl3H2O2 radical-generating method, we have successfully characterized by EPR at ca. 25°C the radicals formed from the substrate n-propyl formate: CH3CH2ĊHOCHO, CH3ĊHCH2OCHO, and ĊH2CH2CH2OCHO. As expected on the basis of previous studies in our laboratory, the first two radicals s...

The rate coefficient of the gas-phase pyrolysis or elimination of exo-2-norbornyl formate was determined in a deactivated, static reaction vessel over the temperature range 300–350 °C and pressure range 41–105 Torr. The substrate exo-2-norbornyl formate yielded surprisingly exo-2-norborneol a...

In this study, the oxidation of propyl acetate (PA) was investigated experimentally in a jet-stirred reactor and theoretically by electronic structure calculations. Experiments were performed at 1 and 10 atm for three different equivalence ratios (φ = 0.5, 1, and 2) at each pressure. These expe...

Recently the possibility of hot β-scission pathways gained attention. These reactions give a shortcut during the important fuel consumption phase in combustion processes leading from H-atom abstraction directly to the β-scission products without fuel radical thermalization. Methyl formate (MF)...

The mechanism for the chlorine initiated oxidation reaction of n-butyl formate has been determined in the presence and absence of NO2. Chlorine atoms initiate the oxidation at five different sites of the molecule, leading to the formation of carbonylic and dicarbonilic species, nitrates, and a n...

Solubility, critical states and liquid-liquid equilibrium (LLE) in the quaternary reacting system formic acid – ethanol – ethyl formate – water and in the ternary subsystems formic acid – ethyl formate – water and ethanol – ethyl formate – water were studied experimentally at 298.15 K and...
