Composites are very difficult to recycle and the team at the University of Birmingham has developed a process called solvolysis
to illustrate that composites can be recycled and used in manufacturing processes with industry.
Composites are very difficult to recycle but the team at the University of Birmingham has developed a new technique using a process called solvolysis
Professor Leeke and his team developed a technique using a process known as solvolysis
to recycle composite materials, a process that is notoriously difficult.
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
of whole biomass hemicellulose by hot compressed liquid water.
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]).
