IRAN ABSTRACT: In this work, the solubility of nicotine extracted from tobacco leaves, incumbrance in the north of Iran, in supercritical carbon dioxide has been measured. in any case the effects of pressure, temperature, extraction cut down time, and the organic co-Solvent on the measuring of nicotine extracted from tobacco leaves have been investigated. It should be stressed that in target to reduce signifi spatetly the enumerate of experiments, the experiments have been specified frame on the Taguchi observational design. The results obtained from the experiments showed that at the specified pressure, temperature, volume of record changer and dynamic time, the maximum get of nicotine can be extracted. The experimental data collected in this research has been correlated using the Redlich-Kwong (R.

K) equation of state. The results showed that the conventional 3-dimensional R.K equation of state can accurately correlate the experimental solubility data with unsloped accuracy. KEY WORDS: critical extraction, Nicotine, Tobacco leaves, Equation of state, RK. insane asylum Nicotine is an alkaloid found 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 biosynthesis taking place in the root and accumulating in the leaves. The molecular(a) structure of nicotine is presented in Fig. 1. * To whom arrangement should be...If you want to get a full essay, order it on our website: Orderessay
