ZSM-5 is a crystalline a!uminosilicate material with a 3-dimensional pore structure. ZSM-5 is usually synthesi:::ed using the hydrothermal method This method uses water as a solvent where the presence of this water will produce a large enough amount of waste so that many reagents are lost in the synthesis process, and make this process not adopt an environmentally friendly chemical process. Therefore, this problem can be overcome by using synthesis techniques without solvents. In this study, the . ynthesis of ZSM-5 was carried out by a technique without solvents using N-Methyi-2-Pyrrolidone (NMP) as a structure­ directed organic compound (OSDA). This study tested several syntheszs parametersfor ZSM-5 crystalli:::ation such as NMP Si ratio (0; 0.02; 0.04; 0.06; 0.08) and synthesis time (0. 6, 12, and 2-1 hours). The resulting ZSM-5 was characteri:::ed by using XRD. ATR-JR, SE/14 TGA, and NMR. The results showed that the optimum conditions were achieved at a ratio of NMP Si = 0.0-1 and synthesis time for 2-1 hours at 180 ° C.
