چکیده

Further to Part I of our study glycol ether binary mixtures [Dimitrov, O.; Ind. Eng. Chem. Res. 2021, 60, 9602−9612], this second part is concentrated around the vapor–liquid equilibrium (VLE) modeling involving three ethers previously studied experimentally. The authors propose use NRTL-PR model for representation these nonideal mixtures. main difficulties related very low vapor pressures and approach cope with them are highlighted. unknown critical parameters DPM, DPnB, PnB were determined using robust group contribution methods. However, experimental values have never been published before. goal was obtain most satisfactory data provided in I. Some issues that mostly occurred as well having encountered. Nevertheless, general a measured points has obtained regardless those issues.

Ethylene glycol monomethyl ether and propylene glycol monomethyl ether: metabolism, disposition, and subchronic inhalation toxicity studies.

Short-term and subchronic vapor inhalation studies have shown that there are pronounced differences in the toxicological properties of ethylene glycol monomethyl ether (EGME) and propylene glycol monomethyl ether (PGME). Overexposure to EGME has resulted in adverse effects on testes, bone marrow and lymphoid tissues in laboratory animals. PGME does not affect these tissues, and instead, overexp...

Reproductive toxicology. Propylene glycol monomethyl ether.

The SV40 small t antigen (ST) is a potent oncoprotein that perturbs the function of protein phosphatase 2A (PP2A). ST directly interacts with the PP2A scaffolding A subunit and alters PP2A activity by displacing regulatory B subunits from the A subunit. We have determined the crystal structure of full-length ST in complex with PP2A A subunit at 3.1 Å resolution. ST consists of an N-terminal J d...

Review of glycol ether and glycol ether ester solvents used in the coating industry.

Ethylene oxide-based glycol ether and glycol ether ester solvents have been used in the coatings industry for the past fifty years. Because of their excellent performance properties (evaporation rate, blush resistance, flow-out and leveling properties, solubility for coating resins, solvent activity, mild odor, good coupling ability, good solvent release) a complete line of ethylene oxide-based...
