Pemurnian asap cair tembakau menggunakan barang aktif=purification liquid smoke from leaf tobacco with activated carbon

ABSTRACT Tobacco smoke contained both a particulat and gaseous phase. Many compounds associated with tobacco smoke were known to cause certain health risks i.enicotine, nitrosamine, PAH compound etc. An alternative methode to minimize health risks was to produce liquid smoke and purification with activated carbon. The pirolysis was carried out in a reactor at 400°C during 2.5 hours followed by condensation through in cold water condenser. These liquid smoke contained various compound such as 0.475% acid, 6.7% carbonyls, 0.74 %phenolic, 0.917% nicotine and 2.70% tar and after purification had 0.62 % acids, 6.97% carbonyls, 0.68% phenol, 1.12% nicotine dan 3,84% tar. Activated carbon could be reduced pycolin, spyrohexanone, cyclobutane. Liquid smoke was extracted exhaustively using dichloromethane as solvent. Qualitative analysis of the extract was performed by means of Gas Chromatography and Mass Spectroscopy (GC-MS). Result of GC-MS showed that liquid smokes comprise least 25 macrocomponents. From GC/MS spectra were identified as methyl pyrazine, acethylene, dimethylpyrazine, 2,4-hexadienal, phenol, dimethyl-ethyl pyrazine, trimethyl-ethylpyrazine, ethyl-dimethylpyrazine, diethyl-methylpyrazine, cyclobutane, butanamide, nicotine, myosmine, nornikotin dan 3-methylene-nonane.
