A competitive indirect enzyme-linked immunosorbent assay (ciELISA) was developed for detection of tris(2,3-dibromopropyl) isocyanurate (TBC). Polyclonal antibodies against TBC were raised from synthesized haptens and then screened against various coating antigens. After optimization of the immun...
A single ip injection of the carcinogenic flame retardant, tris(2,3-dibromopropyl) phosphate (TRIS-BP), when administered to male Sprague-Dawley rats, caused polyuric acute renal failure with tubular necrosis involving the late proximal tubule. Glomerular filtration rate and in vitro transport o...
Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a heterocyclic brominated flame retardant and posses typical characteristic of Persistent Organic Pollutants (POPs). To meet the need for rapid and reliable monitoring of TBC, a monoclonal antibody was produced and an indirect competitive enzyme-lin...
The flame retardant tris(2,3-dibromopropyl)phosphate (Tris–BP) and its metabolite 2-bromoacrolein (2BA) are very potent bacterial mutagens in Salmonella typhimurium (S. typhimurium) TA 100. In this study, we showed that 2BA and Tris–BP are also mutagenic in S. typhimurium TA 104, which detects...
Microplastics and organophosphate esters are ubiquitous pollutants in the marine environment. However, their interactions are poorly understood. In the present study, the sorptions of tri-n-butyl phosphate (TnBP) and tris(2-chloroethyl) phosphate (TCEP) on polyethylene (PE) and polyvinyl chlorid...
Phosphate ester flame retardants (126-71-6, 126-73-8, 78-51-3, 115-86-6, 13674-84-5, 13674-87-8, and 115-96-8) are a group of anthropogenic chemicals added to consumer and industrial products so as to reduce flammability. This group of chemicals has generally similar properties but slightly diff...
The enthalpies of vaporization of several trialkyl phosphates such as, tri-n-butyl phosphate (TBP), triisobutyl phosphate (TiBP), tri-secondary butyl phosphate (TsBP), tri-n-amyl phosphate (TAP), triisoamyl phosphate (TiAP), Tri-2-methyl butyl phosphate (T2MBP), tri-secondary amyl phosphate (TsA...
The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as envi...
A toxicologic and dermatologic review of linalyl benzoate when used as a fragrance ingredient is presented.
The self-diffusion coefficient, the spin-lattice relaxation times and ionic conductivity of lithium ions in liquid mixtures composed of bis(2-ethylhexyl)amine (BEEA) and bis(2-ethylhexyl)phosphoric acid (HDEHP) have been thoroughly investigated as a function of composition and temperature by NMR...
The equilibrium vapor pressures, pe, of the ionic liquid tetraoctylphosphonium bis(2-ethylhexyl)phosphate ([P8888][DEHP]) over the temperature range 409–495 K were determined for the first time using mass loss Knudsen effusion. The pe versus temperature relationship compares well to 1-methyl-3-...
A high-pressure flow calorimeter has been used to determine highly accurate isobaric heat capacities for different viscous fluids, squalane (SQN), bis(2-ethylhexyl) sebacate (DEHS) and bis(2-ethylhexyl) phthalate (DEHP) from T = (293.15 to 353.15) K and up to 30 MPa. The experimental device was ...
The aim of this study was to investigate the acid catalysis of boron phosphate (BP) to model compound dipentaerythritol (DPER) which acted as char source during the thermal degradation and combustion. Various amounts of BP were added in DPER and then the thermal degradation and combustion behavi...
To perform an appropriate selection of the lubricants in air conditioned systems working with carbon dioxide as refrigerant, the thermodynamic behavior of the CO2 + lubricant systems must be well known. In this work we present a new setup to prepare compressed gas–liquid mixtures and to determi...
A melamine polyphosphate (MPP)/dipentaerythritol (DPER) mixture was used as fire retardant additives for preparing waterborne intumescent fire resistive coating. The thermal degradation of the MPP/DPER mixture and of the coating was studied by TGA and FTIR. The resulting char of the coating was ...
In this study, multi-acrylate based dipentaerythritol penta-/hexa-acrylate (DPEPA) was exploited for fabrication of highly cross-linked hybrid monolithic column by copolymerization with polyhedral oligomeric silsesquioxane methacryl substituted (POSS-MA) via a “one-pot” method. The new DPEPA-P...
Synthesis of dipentaerythritol (DPE) by dehydration of pentaerythritol (PE) has been studied using heteropoly compounds and various solid acids. Heteropoly compounds such as H3PW12O40, H4SiW12O40 and their supported catalysts were found to be effective. The addition of water in the reactant supp...
The synergistic barrier effect of aluminum phosphate (AlPO4) on the char-formation behavior of flame-retarded polypropylene (FR-PP) based on the ammonium polyphosphate (APP)/dipentaerythritol (DPER) system was investigated. The flame-retardant property and combustion behavior of FR-PP was studie...
Dipentaerythritol (DPER), 4, 4′-diphenylmethanediisocyanate (MDI) and melamine (MEL) are used as raw materials to microencapsulate ammonium polyphosphate (MAPP) in situ polymerization. The MAPP is characterized by Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), transmiss...
A solvent-borne poly(vinyl acetate)-based intumescent paint containing ammonium polyphosphate, melamine, zinc borate (ZB) and dipentaerythritol (DPER) was modified with powdered poly(ethylene terephthalate) (PET) from post-customer bottles; the polymeric microfiller substituted 6–50 wt.% of DPE...
