Abstract: A vaporizing device generally having a tank, power component, battery, and shroud is disclosed. The power component may include a frame defining a slot configured to receive the tank in an upright position, such that a portion of the tank is adjacent to the power component when the tank is in position. The battery may be coupled to the frame of the power component. The shroud may be configured to be positioned around the battery and coupled to the frame. The battery may be activated when the shroud is compressed radially inward. The device may include a port for connection to an external power supply for recharging the battery. The device may be portable with a generally compact configuration in order to allow a user to comfortably hold the device in the palm of the hand.

Abstract: The present disclosure generally relates to methods of preparing nicotine and resolving R,S nicotine to enrich the (S)(?) enantiomer. The method may comprise combining N-methyl-2-pyrrolidone or a salt thereof with a nicotinate compound in the presence of a solvent and a strong base to form 1-methyl-3-nicotinoyl-2-pyrrolidone or a salt thereof; and reducing the 1-methyl-3-nicotinoyl-2-pyrrolidone or salt thereof in solution with Na2S2O4 to produce racemic nicotine or salt thereof. Resolving the racemic nicotine (or other enantiomeric mixture) may comprise combining the nicotine with (?)-O,O?-di-p-toluoyl-L-tartaric acid (L-PTTA).
