GREEN SYNTHESIS OF MCM-49 ZEOLITE USING LOW TOXICITY TEMPLATE
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
MCM-49 zeolites have been synthesized by dynamic hydrothermal method with piperazine (PIP) as low toxicity template to replace traditional cancerogenic hexamethyleneimine (HMI). The structure and physical-chemical properties of synthesized samples were studied by means of various characterization techniques, such as XRD, SEM, N2 adsorption-desorption, and NH3-TPD. The effects of PIP to HMI ratio in composite template were investigated. Results show that high crystalline and high purified MCM-49 zeolites could be synthesized using PIP as template to completely or partially replace HMI.
