PCC telah disintesis dengan mereaksikan reacting HCl dan CrO 3 , diikuti dengan penambahan piridin dalam larutan pada suhu 0 o C dan hasilnya 85%. Sedangkan, reaksi oksidasi dari 3-(3,4-dimetoksfenil)-propanol dengan PCC sebagai oksidator dilakukan dalam diklorometan selama 3 jam dan direfluks pada suhu 30 o C dan rasio mol alkohol:PCC adalah 1:2. Produk oksidasi diekstraksi menggunakan dietileter dan diuapkan, menghasilkan 71,3% dari produk oksidasi dengan indeks refraksi sebesar 1,57. Data FT-IR menunjukkan adanya penyerapan yang kuat pada gugus karbonil (C=O) pada bilangan gelombang 1724,2 cm -1 dan penyerapan CH aldehida pada 2723,3 cm -1 , diperkuat oleh data GC-MS di t R = 20.797 menit yang menunjukkan ion molekuler pada m/e = 194 dan puncak dasar pada m/e = 151 yang mewakili struktur 3-(3,4-dimetoksfenil)-propanal}, issn = {2597-9914}, pages = {72--77} doi = {10.14710/jksa.10.3.72-77}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/3282} }
