The difference of enzymatic degradation behavior between Poly (butylene succinate-co-diethylene glycol succinate) (PBS-co-DEGS) and Poly (butylene succinate-co-butylene diglycolic acid) (PBS-co-BDGA) was studied in a Tetrahydrofuran (THF)/toluene mixed system by Novozym 435 (N435, immobilized Ca...

Diethylene glycol (DEG) is a solvent used in consumer products allowing the increased risk for consumer exposure. DEG metabolism produces two primary metabolites, 2-hydroxyethoxyacetic acid (2-HEAA) and diglycolic acid (DGA). DGA has been shown to be the toxic metabolite responsible for the prox...

Diglycolic acid (DGA) is present in trace amounts in our food supply and is classified as an indirect food additive linked with the primary GRAS food additive carboxymethyl cellulose (CMC). Carboxymethyl starches are used as a filler/binder excipient in dietary supplement tablets and a thickenin...

Biosorption has recently attracted much attention as an alternative to conventional techniques for the recovery of rare earth elements (REEs). In this study, Escherichia coli (E. coli) was chemically modified to improve its performance as a biosorbent for REEs. The diglycolic amic acid group, wh...

Diglycolic acid (DA) polymer was coated on glassy carbon (GC) electrode by cyclic voltammetry (CV) technique for the first time. The electrochemical performances of the modified electrode were investigated by CV and electrochemical impedance (EIS). The obtained electrode showed an excellent elec...

The acute oral toxicity of diglycolic acid (DGA) was evaluated. Groups of female rats (n = 8 rats/group) received 28 consecutive daily single doses of 0.3, 1.0, 3.0, 10.0, 30.0, 100.0 or 300.0 mg DGA/kg body weight by gastric intubation. One group of animals served as vehicle control. Tissues an...

Carboxymethyl starches are added to food products for thickening or tablet binding/filling purposes. Although they lack toxicity, their synthesis creates the chemical byproduct diglycolic acid (DGA), which is difficult to eliminate and whose toxicity is in question. A rare case of an accidental ...

In environmental industry, capturing of acid gases, particularly CO2, has always been a major problem. The different techniques such as absorption and adsorption processes have been used for removal of acid gases from flue and natural gases. In recent years, a new type of solvent, known as green...

Absorption processes using aqueous alkanolamines are under intense research for new gas purification and carbon capture applications. In this work continuous flow calorimetry (SETARAM C80) and vibrating tube densimetry were used to measure absorption enthalpies of carbon dioxide (CO2) into aqueo...

Aminoalcohols differ in mammalian toxicity at least in part based upon their ability to alter the metabolism of phospholipids and to cause depletion of the essential nutrient choline in animals. This study examined the incorporation of diisopropanolamine (DIPA) into phospholipids (PLs) and effec...

The chemical absorption rate of carbon dioxide with diisopropanolamine (DIPA) was measured in such non-aqueous solvents as methanol, ethanol, n-propanol, n-butanol, ethylene glycol, propylene glycol, and propylene carbonate, and aqueous solvent at 298 K and 101.3 kPa using a semi-batch stirred t...

The vapour–liquid equilibrium (VLE) of the systems of water + methyldiethanolamine (MDEA) and water + diisopropanolamine (DIPA) was measured at several temperatures with a static total pressure apparatus. The solid–liquid equilibrium (SLE) of the same systems was measured at low amine concentr...

The effect of ethanol-diisopropanolamine (EDIPA) on the hydration and mechanical properties of Portland cement was focused on in this study. A combination of isothermal calorimetry, X-ray powder diffraction (XRD) and differential scanning calorimetry (DSC)-thermogravimetric (TG) analysis was use...

The solubility of CO2 in the aqueous solutions of diisopropanolamine (DIPA) blended with N-(2-aminoethyl) ethanolamine (AEEA) and piperazine (Pz) is measured using a static equilibrium cell through a high pressure double-wall reactor. The different aqueous amine mixtures are used as the followin...

Aqueous secondary and tertiary alkanolamine mixtures are novel absorbents for carbon dioxide removal. This study evaluates the CO2 absorption by aqueous mixtures of diisopropanolamine (DIPA) and triethanolamine (TEA) in a bubble column reactor considering the influence of the mixture composition...

Phase equilibrium measurements were conducted for H2S + water + diisopropanolamine (DIPA) systems with a static total pressure method. The measured systems had DIPA mass fractions from 0.10 to 0.35. Each DIPA solution was measured at several temperatures ranging from 322 K to 353 K. The measurem...

In recent years, emission of greenhouse gases especially carbon dioxide has been increased so that CO2is accounted for as a gas pollutant and leads to global warming. Thus, the removal of carbon dioxide is an important step in a gas capturing process. The absorption of CO2 in a mixture of alkano...

The endocannabinoid system (ECS) regulates several physiological processes in the Central Nervous System, including the modulation of neuronal excitability via activation of cannabinoid receptors (CBr). Both glutaric acid (GA) and quinolinic acid (QUIN) are endogenous metabolites that, under pat...

Via heat of hydration, Pb(II) imprinted membrane composite adsorbent was prepared using glutaric acid as modifier, Pb(II) as imprinted ion, chitosan-blended polyvinyl alcoho as support material, and glutaraldehyde as cross-linking agent. The structure and morphology of the adsorbent were charact...

Cocrystal formation may affect manufacturability (flow, compaction and processability) as well as solubility/dissolution, hygroscopicity and stability properties of drugs. Therefore, cocrystallization could be used to improve the pharmaceutical properties of low-soluble drugs such as ethenzamide...
