IRAN ABSTRACT: In this work, the solubility of nicotine extracted from tobacco leaves, military unit in the north of Iran, in supercritical carbon dioxide has been measured. excessively the effects of pressure, temperature, extraction slash time, and the organic co-Solvent on the bar of nicotine extracted from tobacco leaves have been investigated. It should be stressed that in ball club to reduce signifi bathtly the count of experiments, the experiments have been specified establish on the Taguchi observational design. The results obtained from the experiments showed that at the specified pressure, temperature, volume of auto-changer and dynamic time, the maximum mensuration of nicotine can be extracted. The data-based data collected in this research has been correlated development the Redlich-Kwong (R.

K) equation of state. The results showed that the conventional third-dimensional R.K equation of state can accurately correlate the data-based solubility data with mature accuracy. KEY WORDS: critical extraction, Nicotine, Tobacco leaves, Equation of state, RK. trigger Nicotine is an alkaloid put in in nightshade family of plants (solanaceae), broadly in tobacco, and less in tomato, potato, eggplant and green-pepper. It is also found in coca leaves. Nicotine constitutes 0.3 to 5 % of tobacco plant by dry weight; with biogenesis taking place in the root and accumulating in the leaves. The molecular structure of nicotine is presented in Fig. 1. * To whom placement should be...If you want to get a full essay, order it on our website: Ordercustompaper.com
