More Information
Summary:The disclosure describes methods for providing nicotine isolates, including: receiving a solution containing nicotine derived from green tobacco biomass of a plant of the Nicotiana species; converting the nicotine to nicotine sulfate; concentrating the resulting nicotine sulfate-containing solution; adjusting the pH of the resulting nicotine sulfate concentrate to a pH of about 9.5 or greater to convert the nicotine sulfate to nicotine in free base form; extracting the resulting basic concentrate with an organic solvent to partition the nicotine into the organic solvent; and distilling the nicotine-containing organic solution to afford a nicotine isolate comprising about 90% or more nicotine by weight.
