Description
Verfahren zur Herstellung von Sulfonsäuren aus Fetten und Ölen Beim .Sulfonieren von ölen und Fetten bzw. deren freien Säuren, z. B. Olivenöl, Rizinusöl, Tranen, Rüböl, Leinöl, Tallöl usw., werden bekanntlich Körper erhalten, die eine weitgehende technische Verwendung z. B. in der Textil- und Lederindustrie gefunden haben. Unter ihnen ist das Türki,s.chro.töl, ein sulfoniertes Rizinusöl, von größter praktischer Bedeutung. Alle derartigen Produkte zeigen eine geringe Kalk- und Säurebeständigkeit, ein Umstand, oder .beim Arbeiten mit harten oder säurehaltigen Wässern von Nachteil ist und gegebenenfalls die Anwendung solcher Türkischrotöle verbietet.Process for the production of sulfonic acids from fats and oils Beim .Sulfonation of oils and fats or their free acids, e.g. B. olive oil, castor oil, Tears, rapeseed oil, linseed oil, tall oil, etc., are known to get bodies that have a extensive technical use z. B. found in the textile and leather industry to have. Among them, the Türki, s.chro.töl, a sulfonated castor oil, is the greatest practical importance. All such products show a low resistance to lime and acids, a fact or disadvantage when working with hard or acidic water and possibly prohibits the use of such Turkish red oils.
Man .gelangt nun, wie gefunden wurde, zu sehr kalk- und säurebeständigen Sulfonsäuren derartiger öle und Fette, wenn man sie mit Chloracetylchloridsulfonsäure bei gewöhnlicher oder erhöhter Temperatur behandelt. Man erhält die Chloracetylchloridsulfonsäure z. B. durch Einwirkung von Schwefelsäure auf Trichloräthylen (vgl. die französische Patentschrift 6o2 395). Beispiel ioo Teile Rizinusöl werden unter Rühren bei 3o bis 35° langsam mit ioo bis i5oTeilen Chloracetylchloriidsu;lfonisäure versetzt. Man rührt noch etwa 12 bis 15 Stunden nach 'wn:d trägt hierauf das Reaktionsgemwsch in etwa Zoo Teile Was.servon 50° ein, trennt cl@iei Sulfo@n; säure von der sauren Lösung und wäscht mit kochsalzhaltigem Wasser aus. Die ,so .gereinigte Sulfonsäure kann unmittelbar oder nach einer teilweisen Neutralisation verwendet werden. Sie .gestattet im Gegensatz zum Türkischrotöl auch ein Arbeiten in hartem und säurehaltigem Wasser.As has been found, one now arrives at very lime- and acid-resistant Sulphonic acids of such oils and fats when mixed with chloroacetylchloride sulphonic acid treated at ordinary or elevated temperature. The chloroacetyl chloride sulfonic acid is obtained z. B. by the action of sulfuric acid on trichlorethylene (cf. the French Patent 6o2 395). Example 100 parts of castor oil are stirred at 3o 100 to 150 parts of chloroacetylchloride sulfonic acid are slowly added up to 35 °. The mixture is stirred for about 12 to 15 hours after wn: d then carries the reaction mixture roughly zoo parts of Was.servon 50 °, separates cl @ iei sulfo @ n; acid from acidic Solution and wash out with saline water. The so purified sulfonic acid can be used immediately or after partial neutralization. she In contrast to Turkish red oil, it also allows you to work in hard and acidic Water.
