In the case of PET, there are several chemical conversion ways for chemical recycling: hydrolysis, alcoholysis, acidolysis, aminolysis
, methanolysis, and glycolysis , The products obtained by each way are: terephthalates, esters, acids, amides, dimethyl terephthalates and bis(2-Hydroxyethyl) terephthalates, respectively.
The role of the hydrogen bond between the oxygen atoms of the oxirane ring and the hydrogen for hydrogen bonding of the hydroxyl group during the aminolysis
of epoxy compounds has been considered in a number of works.

They have acquired specific interest over few decades due to their capability to act in microaqueous environments and stimulate esterification, transesterification, aminolysis
, acidolysis reactions (2,3).
Substituted 1,8-naphthalimide derivatives (2c-2f) were synthesized from the appropriate 1,8-naphthalic anhydrides via aminolysis
with Boc-protected hexylenediamine (Scheme S1, SI).

In the first step, soybean oil was converted into mono hydroxyl functional soy derivatives through the aminolysis
reaction with ethanolamine.

Then the resultant lactone was subjected to aminolysis
(Nicolas et al., 2006) by treating with DIBAL-H-[H.sub.2]NR complex in THF to afford the amides 14-18 in good yields.
This property makes possible for them to execute a number of catalytic reactions such as alcoholysis acidolysis aminolysis
esterification and transesterification (Coradi et al.
The steadily growing interest in lipases over the last two decades stems from their biotechnological versatility and the enzymes' ability to catalyze a broad spectrum of bioconversion reactions such as hydrolysis, esterifications, transesterifications, aminolysis
and others (MINOVSKA et al., 2005).
