In the case of PET, there are several chemical conversion ways for chemical recycling: hydrolysis, alcoholysis, acidolysis,
aminolysis, methanolysis, and glycolysis [5], The products obtained by each way are: terephthalates, esters, acids, amides, dimethyl terephthalates and bis(2-Hydroxyethyl) terephthalates, respectively.

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).
