LASC catalyst synthesis process was carried out using iron metal (Fe) and its characterization properties were tested. There are five stages out, namely, the manufacture of Fe(DS)3 catalyst, lactic acid dehydration, polycondensation into l-lactic oligomers (OLLA), depolymerization l-lactide, ROP to convert l-lactide Polymers. (PLLA). The analysis used is as follows, Karl-Fisher; Spectroscopy Fo...
