PENGARUH WAKTU HIDROTERMAL DAN TMAOH DALAM SINTESIS LANGSUNG MCM-41

Abstract

The MCM-41processing synthesis with variation time hydrothermal and TMAOH at direct
synthesis process has been done. The synthesis of MCM–41 was used templating agents with
cetiltrimetilammonium bromide (CTAB). The optimization of synthesis of MCM-41 was carried out
to produce good material characteristics. Hydrothermal time variation performed in the synthesis of
MCM-41 for 18 hours, 24 hours, 48 hours and 88 hours has been done. So the study of effect TMAOH
was used CTAB/ TMAOH ratio: 1 and 1.25. The results showed that the 24- hour time hydrothermal
was able to produce the good crystallinity with 100% relative crystallinity. However, the best stability
of MCM-41 materials synthesized in hydrothermal time during the 48 hours. So the effect of
TMAOH additions in the synthesis MCM-41 can bedecreased crystallinity of MCM-41.
