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.
