A device for a cigarette tipping paper anti-adhesion test is disclosed. The device includes the following components: an upper cover (), a plurality of upper cover semi-cylinders () inside the upper cover, having the same radius and arranged in parallel, and a box () with a plurality of holes () on the box upper surface (), connected with the inner cavity of the box (). Each upper cover semi-cylinder has a cross-section with a bow shape. The side wall of the box () also has an opening (). A method for testing anti-adhesion of the cigarette tipping paper using the device is also disclosed. The present device can qualitatively and quantitatively simulate adhesion of tipping paper in various conditions.

Device for cigarette tipping paper anti-adhesion test and its application method

A (Z)-solanone has the steric formula of: or with the name of (S,Z)-5-isopropyl-8-methyl-6,8-diene-2-one or (R,Z)-5-isopropyl-8-methyl-6,8-diene-2-one. A process for the preparation of the (Z)-type solanone and the use thereof in flavoring of cigarette shred are further disclosed. The process includes the following steps: (1) reacting isopentanal and methyl vinyl ketone, under the action of a catalyst and a co-catalyst, to give (S)-2-isopropyl-5-carbonylhexanal or (R)-2-isopropyl-5-carbonylhexanal; (2) reacting the (S)-2-isopropyl-5-carbonylhexanal or the (R)-2-isopropyl-5-carbonylhexanal obtained in step (1) with (iodomethyl)triphenylphosphonium iodide, to give (S,Z)-7-iodo-5-isopropyl-6-ene-2-one or (R,Z)-7-iodo-5-isopropyl-6-ene-2-one; and (3) reacting the (S,Z)-7-iodo-5-isopropyl-6-ene-2-one or the (R,Z)-7-iodo-5-isopropyl-6-ene-2-one obtained in step (2) with pinacol isopropenylborate in the presence of a catalyst to give the (Z)-solanone.
