Abstract

The need of glyphosate in Indonesia is increasing by about 0.75% annually. Nowadays, Indonesia imports the compound from China. In order to decrease the amount of imported glyphosate, it is necessary to produce it locally. This research aims at achieving primary reaction rate of producing glyphosate from neophosphonomethyl iminodiacetic Acid (NPMIDA) and hydrogen peroxide (H2O2), and secondary reaction rate of aminomethylphosphonic acid (AMPA) at various reactant ratios and temperatures. Palladium supported alumina (Pd/Al2O3) was used as catalyst. Five grams of NPMIDA was added into a-500 mL three neck flask, and 85 mL aquadest was poured into it. Then, 1 mL H2O2 was added into the three neck flask every 20 minutes.. The product was vacuum-filtered and reacted with 130 mL ethanol. Separation of glyphosate was performed by filtering and washing it with ethanol and diethyl ether. The purity of glyphosate product was analyzed using UV/Vis spectrometer.
