There are different methods for the chemical recycling of waste PET, namely, hydrolysis [12, 14, 15], glycolysis [10, 16, 17], simultaneous hydrolysis-glycolysis , aminolysis
[19-21], and aminoglycolysis [20, 22, 23], Hydrolysis of PET can be carried out as alkaline , acid , and neutral hydrolysis , EG and terephthalic acid (TPA) or oligomers with carboxyl end groups are obtained by hydrolysis of PET dependent on process conditions , Glycolysis is a depolymerization method commonly used in chemical recycling of waste PET.
Then the resultant lactone was subjected to aminolysis
(Nicolas et al.
In addition to hydrolyzing long-chain triacylglycerols, they can catalyze esterification, transesterification, acidolysis, alcoholysis, and aminolysis
2,4,6-Tris(phenoxy)-1,3,5-triazine reacts with aliphatic amines in aminolysis
, and this reaction can be used to give dendrimers.
In addition to their hydrolytic activity on triglycerides, lipases catalyze esterification, transesterification, acidolysis, alcoholysis and aminolysis
Specifically, we demonstrate how these derivatives undergo aminolysis
under mild conditions with both protected and unprotected amino acids, giving rise to stable thioamide species.
He begins with the fundamentals of peptide synthesis, emphasizing the intermediates that are encountered in aminolysis
This polymer consists of multi-block backbone and aminolysis
derivatives on the side chains.
N,N,N',N'-tetraaryl-R,R-tartramides 4 and 5 were prepared from 2,3-O-isopropylidene-R,R-tartryl chloride 1 by aminolysis
of the corresponding secondary amines (Scheme 1).
The amines released from some accelerators during vulcanization might lead to this degrading phenomenon called aminolysis
and ammonolysis of carboxylic acid derivatives:
The chemical depolymerization processes include methanolysis, hydrolysis, glycolysis, aminolysis
, and amonolysis, wherein glycolysis being the most studied ones since many years [3-5].
