7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-enium acetate (mTBD acetate) is a protic ionic liquid that is being investigated for use in industrial processes, such as for producing textiles from cellulose. To aid in designing such processes, we have measured the densities, viscosities, and thermal conductivities of mTBD acetate and aqueous mixtures containing mTBD acetate. We also investigated how excess amounts of mTBD or acetic acid affect the density, and found that in general an excess of either component decreases the density. However, when no water is present, the sample with excess acetic acid actually has a slightly higher density than when there is an equimolar amount of acid and base. The maximum density occurs when some water is present (around 30-40 mol%). We also modeled the density data using the ePC-SAFT equation of state and provide simple correlations for calculating the viscosity and thermal conductivity of these mixtures.

The kinetic equation for the nitrous acid catalysed nitration of naphthalene in aqueous mixtures of sulphuric acid and acetic acid has at least two kinetic terms: one first order with respect to naphthalene and one second order with respect to naphthalene. The orders with respect to nitrous acid and nitric acid vary with the conditions in the way characteristic of the electron transfer mechanism of this reaction. The second-order term with respect to naphthalene is considered to derive from the formation of the dimeric radical cation (ArH)2+•. The acidity dependence of the rate coefficients and the absence of a normal isotope effect in the reaction of naphthalene-d8 are consistent with this interpretation. Keywords: naphthalene, nitration, nitrous acid.

Periodic acid (1% w/v) solvated by anhydrous dimethyl sulfoxide (DMSO) readily induced a strong Schiff reaction in a variety of structures containing polysaccharides, but not glycogen. With the increasing amounts of water added to DMSO, glycogen was also oxidized, while the selective localization of other polysaccharides remained unimpaired. Periodate, solvated in the anhydrous acetic acid-DMSO mixture, rapidly induced concomitant oxidation of nucin and glycogen-containing structures. Sodium bisulfite addition derivatives of carbonyls, induced by periodate oxidation in DMSO, were stained meta- and orthochromatically with toluidine blue at controlled pH. Certain metachromatic tissue components were strongly birefringent in polarized light in contrast to the identical structures oxidized by aqueous periodate. Marked differences in staining reactions elicited in identical structures by periodate in DMSO as compared with aqueous periodate suggest that DMSO-periodate method considerably enhances the range of histochemical oxidations by periodate.
