PATENTAMT.PATENT OFFICE.
Isobutylalkohol und Metaxylol vom Siedepunkte 1370 C. werden in äquivalenten Mengen gemischt und nach und nach in 5 Theile concentrirte Schwefelsäure von 66° B. unter guter Abkühlung eingetragen, um zu vermeiden, dafs sich schweflige Säure bildet. Nach einiger Zeit der Ruhe wird das Gemisch mit der etwa vierfachen Menge Wasser verdünnt, um das noch unangegriffene Condensationsproduct abzuscheiden; dasselbe sammelt sich in Form einer Oelschicht auf der. Flüssigkeit und wird nach vollständiger Abscheidung entfernt. Die untere, klare, wässerige, rosenfarbene Flüssigkeit wird zur Gewinnung der Paraisobutylxylolsulfosäure mit gesättigter Kochsalzlösung versetzt, bis sich der Kolbeninhalt nach einiger Zeit mit weifsen Krystallen durchsetzt hat. Durch Abfiltriren werden die Krystalle gesammelt, durch Umkrystallisiren gereinigt, ausgepreist und bei ioo° G. getrocknet.Isobutyl alcohol and metaxylene from the boiling points of 137 0 C. are mixed in equivalent amounts, and added gradually concentrated in 5 parts of sulfuric acid of 66 ° for example, with good cooling in order to avoid, that forms sulfurous acid. After a period of rest, the mixture is diluted with about four times the amount of water in order to separate out the still unaffected condensation product; the same collects in the form of a layer of oil on the. Liquid and is removed after complete separation. The lower, clear, watery, rose-colored liquid is mixed with saturated sodium chloride solution to obtain the paraisobutylxylene sulfonic acid until the contents of the flask have become permeated with white crystals after a while. The crystals are collected by filtration, purified by recrystallization, priced out and dried at 100 ° G.
