Nitration in the presence of strong acids or Lewis acids Solutions of dinitrogen pentoxide in sulphuric acid nitrate 1,3-dimethyl-benzene-4,6-disulphonic acid twice as fast as a solution of the same molar concentration of nitric acid. This is consistent with Raman spectroscopic and cryoscopic data, which establish the following ionisation ...

A cement slurry additive consisting of methylcellulose, melamine-formaldehyde resin, and trioxane has been proposed for better bonding of cement to the casing string [20]. Bisphenol-A epoxide resins, with amine-based curing agents, sand filler, and a mixture of n-butanol and dimethyl benzene as a diluent, have been proposed as additives to increase adhesion properties of cement [572].

The non-aromatic nature of the pyran-2-one ring is evident in its behaviour as the diene component in Diels-Alder cycloadditions. With dimethyl acetylenedicarboxylate (DMAD, dimethyl but-2-ynedicarboxy-late), for example, it gives an adduct that spontaneously eliminates carbon dioxide to yield dimethyl phthalate (dimethyl benzene-1,2-dicarboxylate) (Scheme 4.7)...
