Abstract

1,024,284. Treating tobacco. PHILIP MORRIS Inc. March 6, 1964 [March 7, 1963], No. 9677/64. Heading A2C. In continuous process for selective removal and recovery of alkaloid from tobacco which includes the steps of extraction of tobacco with organic solvent, contacting the resultant alkaloid-laden solvent extract with brine to remove alkaloid selectively from the extract, re-cycling the alkaloid-relieved solvent to tobacco, recovering alkaloid from the brine and re-cycling the alkaloid-relieved brine for contacting with further alkaloid-laden solvent, the alkaloidladen solvent is contacted with the brine at a temperature substantially below that at which alkaloid untimately is recovered from the brine and at a pH below about 6.5, the resultant alkaloid-enriched brine is then warmed to a temperature at which an alkaloid phase separates from the brine, and the alkaloid phase is thereafter physically removed from the brine. The solvent and brine are contacted at a temperature below 10‹C and at a pH below 4.0. The pH of the alkaloid-enriched brine is increased to between 5.5 and 8, prior to recovery of the alkaloid. The tobacco is treated with organic solvent at a pH between 5.5 and 8, the moisture content of the tobacco being between 10 and 25%.
