Reaksi demetilasi telah dilakukan terhadap garam amonium hetcrosiklik aromatik, N-metilpiridinium iodida dengan menambahkan PPh 3 . Reaksi berlangsung dalam pelarut asetonitril pada temperatur 82°C. Kromatografi lapis tipis (TLC) digunakan untuk mengontrol jalannya reaksi, hasilnya menunjukkan bahwa PPh 3 berperan dalam reaksi demetilasi. Penentuan waktu reaksi dilakukan dengan optimasi waktu reaksi. Hasil analisis menggunakan spektrofotometer UV-Vis menunjukkan bahwa N-metilpiridinium iodida dapat terdemetilasi setelah reaksi berlangsung selama 6 jam dengan transformasi 98 %.}, issn = {2597-9914}, pages = {112--117} doi = {10.14710/jksa.2.4.112-117}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/18924} }
