propylene carbonate

Propylene carbonate is used as a polar, aprotic solvent.

Propylene carbonate is chiral but is used exclusively as the racemic mixture.

Propylene carbonate can also be found in some adhesives, paint strippers, and in cosmetics.

The corresponding reaction of 1,2-propanediol with phosgene is complex, yielding not only propylene carbonate but also oligomeric products.

One example is propylene carbonate with melting point 55 C and boiling point 240 C.

Keywords: propylene carbonate, acetonitrile, correlation factor, excess properties, dielectric constant.

An isomeric derivative is propylene carbonate, a colourless liquid that does not spontaneously polymerize.

Keywords: excess volumes, propylene carbonate, n-alkanols, liquid mixtures, hydrogen bonding.

No significant toxic effects were observed in rats fed propylene carbonate, exposed to the vapor, or exposed to the undiluted liquid.

Other major products are polypropylene glycol, propylene glycol ethers, and propylene carbonate.

In electrospray ionization mass spectrometry, propylene carbonate is doped into low surface tension solutions to increase analyte charging.

Previous work has studied lubricant additives using electrochemistry on relatively polar fluids such as esters and propylene carbonate (PC).

Propylene carbonate product may be converted to other carbonate esters by transesterification as well (see Carbonate ester).

The polarographic reduction of samarium(III) cryptates with cryptands 222, 221, and 22 was investigated in propylene carbonate.

Key words: ionic volumes, propylene carbonate, N,N-dimethylformamide, solvent mixtures, solvation, lithium batteries.

Specifically, solutions of lithium hexafluorophosphate in propylene carbonate and dimethoxyethane serve as an electrolyte in lithium batteries.

Small carbonate esters like dimethyl carbonate, and ethylene and propylene carbonate are used as solvents.

The heat capacities per unit volume and sound velocities of many solutions of 1:1 electrolytes in propylene carbonate (PC) were measured at 25 °C.

Propylene carbonate does not stabilize low oxidation states of lanthanides by cryptation. This is at variance with behavior observed previously in other media like water and methanol.

Radicals formed by γ-irradiation of propylene carbonate (PC) glasses at 77 °K were studied by e.s.r. and optical spectroscopy.

Key words: partial-molar volume, scaled particle theory, lithium salts, propylene carbonate, solvent mixtures, lithium battery electrolytes.

It is possible, for example, to obtain potassium, sodium, and other alkali metals by electrolysis of their chlorides and other salts dissolved in propylene carbonate.

Water is the most common and well-studied polar solvent, but others exist, such as ethanol, methanol, acetone, acetonitrile, dimethyl sulfoxide, and propylene carbonate.

The aprotic solvents studied were nitromethane, nitrobenzene, sulfolane, acetonitrile, propylene carbonate, acetophenone, dimethylformamide, dimethylsulfoxide, and o-dichlorobenzene.

Ethylene carbonate is used as a polar solvent with a molecular dipole moment of 4.9 D, only 0.1 D lower than that of propylene carbonate.
