A method is described for extracting tobacco alkaloids from tobacco in which the tobacco alkaloids are extracted from the tobacco with carbon dioxide under supercritical conditions and the tobacco alkaloids separated from the carbon dioxide, wherein in the carbon dioxide for the extraction of the tobacco alkaloids from the tobacco is mixed with a solid 2 to 3-basic organic acid having a total of 2 to 6 carbon atoms, a monoalkali or monoammonium salts thereof in order to appreciably shorten the extraction times.

Method for extracting tobacco alkaloids

With the present invention a tobacco sheet or foil is proposed which has an elevated filling force and consists of tobacco particles, water, binders and moisturizers, and relatively gas-impermeable, in particular surface-sealed cover layers being connected together by a spongy structure which is formed by gas-filled bubbles, and in which cavities are formed having a shaggy, furrowed and/or torn surface.

A device for determining the concentration of condensable vapor in a flowing gas stream which includes a gas evacuation conduit for receiving a sample of gas from the stream, a gas condenser in the evacuation conduit for condensing out essentially all of the condensable vapors in the sample and a gas flowmeter connected to the gas discharge of the gas condenser for determining the flow of the dry gas sample exiting the condenser. A pump is provided for withdrawing a sample of gas from the flowing gas stream and for conveying this sample at a constant, known volumetric flow through conduit and to the gas condenser and the flowmeter and a control means operatively connected to the flowmeter determines the condensable vapor concentration by comparing the flow of the dry gas sample with the known volumetric flow fed to the condenser.
