Indeed, as acid, ester, alcohol, and carbonate functions are available, transesterifications, alcoholysis, acidolysis
, and carbonate-ester functions can happen.
The process uses optimized acidolysis
and involves feeding polyurethane waste crushed into small pieces into the reactor vessel via a specially designed screw conveyor.
The ECM fungi release elements stored in mineral particles through complexolysis and acidolysis
as these are not readily available for micro-organisms.
In addition to hydrolyzing long-chain triacylglycerols, they can catalyze esterification, transesterification, acidolysis
, alcoholysis, and aminolysis reactions.
In addition to their hydrolytic activity on triglycerides, lipases catalyze esterification, transesterification, acidolysis
, alcoholysis and aminolysis (Table 3).
These reactions include alcoholysis, acidolysis
, and ester exchange that are referred here as transesterification.
Polyester pairs can undergo chemical reactions at high temperatures in the solid state and in the melt, like alcoholysis, acidolysis
, or direct ester interchange [9-11].
Although the process is not completely understood, the literature proposes three potential mechanisms of transesterification-alcoholysis, acidolysis
, and direct ester exchange [22, 23].
of molten PEN is also a very fast reaction.
It is generally known that the transesterification reactions of polyester blends occur in the molten state via alcoholysis, acidolysis
, and direct inter-change reactions, those reactions being as follows (21-24):
According to Porter (5) and Kotliar (6), the molecular weight distribution of blends of polyesters can be altered without changing the number of end groups by alcoholysis, acidolysis
, or by transesterification.
Taking into account that the MA-Li units are involved, the reaction will probably be an intennolecular acidolysis
between PET and PEMA-Li, according to the following scheme (18):
