Description
Najdluzszy czas trwania patentu do 24 wrzesnia 1952 r.W wyniku dalszych badan, dotyczacych patentu nr 25 564 na „Sposób wyosobniania wartosciowych skladników z mialu tytonio¬ wego", stwierdzono, ze zamiast dwukrotne¬ go wylugowywania tytoniu raz w srodowi¬ sku zasadowym, drugi raz w kwasnym, mozna przeprowadzic jednorazowe wylu¬ gowanie za pomoca spirytusu w srodowisku kwasnym, uzyskanym przez obróbke mialu tytoniowego kwasem siarkowym, przy czym uzyskany wyciag spirytusowy po odpedze¬ niu alkoholu rozdziela sie przez dodanie wody na dwie warstwy: zywiczna oraz wodna, która jest kwasna i zawiera nikoty¬ ne, która nastepnie wydziela sie przez od¬ parowanie wodnego roztworu z wapnem do suchosci, po czym z suchej pozostalosci re¬ generuje sie wolne kwasy za pomoca roz¬ wodnionego kwasu siarkowego. W tych wa¬ runkach inne skladniki organiczne wodnej warstwy oprócz kwasów pozostaja w po¬ staci nierozpuszczalnej w wodzie i wobec tego nie przechodza do roztworu. PLThe longest duration of the patent until September 24, 1952. As a result of further research on the patent No. 25,564 for "Method of isolating valuable ingredients from tobacco ground", it was found that instead of leaching the tobacco twice in an alkaline environment, the second time in acid, it is possible to carry out a one-time hatching with spirit in an acidic environment, obtained by treating the tobacco ground with sulfuric acid, the resulting spirit extract, after the alcohol has been stripped off, separated by adding water into two layers: resin and water, which is acidic and contains nicotine, which is then separated by evaporation of the aqueous solution with lime to dryness, and the free acids are then recovered from the dry residue with the aid of diluted sulfuric acid. acids remain in a water-insoluble form and therefore do not go into solution
