a double-decomposition chemical reaction between a solute and solvent that proceeds according to an ionic mechanism. The reaction results in the formation of new compounds. Solvolysis may be reversible (in self-ionizing liquids) or irreversible. In certain solvents it is designated by special terms, for example, hydrolysis in water, alcoholysis in alcohols, and ammonolysis in ammonia.

The increase in cellulose content was indicative of higher resistance to degradation than hemicellulose and lignin in EG solvolysis because of (1) its highly crystalline structure and (2) the structure of the cell wall, where lignin and hemicellulose shield cellulose.
Historically, quantification has been performed with GC-MS after solvolysis and hydrolysis of the conjugate groups (2, 8, 11); however, the presence of the 7[alpha]-hydroxyl group in these atypical bile acids generates an allylic structure in the B-ring of the steroid nucleus that is highly labile and readily degrades under acidic conditions and, in the presence of methanol, yields a series of methoxylated derivatives as artifacts (2, 23).
The one-handed helical poly(D2PyMA) exhibited a slightly lower chiral recognition ability than the PTrMA as a CSP for HPLC, but a better resistance against solvolysis by methanol.

In its simplest terms, the titanate function (1) mechanism may be termed proton (H+) reactive via solvolysis (monoalkoxy) or coordination (neoalkoxy) without the need of water of condensation, while the silane function (1) mechanism may be termed hydroxyl (OH-) reactive via a silanol-siloxane mechanism requiring water of condensation.
Total proanthocyanidin content was determined by measuring at 540 nm the absorbance of the resulting cyanidin chloride, after acid-catalyzed solvolysis with n-BuOH/HCI 37% (95:5), according to the method described for Crataegus in the European Pharmacopoeia (Fur.
However, only a few examples of homogeneous polar reactions, mostly solvolysis and hydrolysis reactions, have been kinetically investigated for sonication effects (for a review see refs [5,6]).
