    Verfahren <SEP> zur <SEP> Heratellung <SEP> von <SEP> Äthylbenzylanilin-3.4'-dihulfosäure.       Es wurde gefunden,     dah        man    die     Äthyl-          benzylariilin-3.4'-disulfosäure    in technisch     schi-          vorteilhafter    Weise durch Kondensation von  1     Dlol.        benzylchlorid-p-sulfosaureni    Natrium  mit 1     Mol.        Monoätbvlmetanilsäure    in wäs  seriger Lösung darstellen kann.

   Man erhält  eine Lösung, welche ohne weiteres zur Her  stellung von     Farbstoffen    verwendet werden  kann, oder aus welcher die     Äthylbeiizylaiiilin-          3#4'-disulfosäure    nach bekannten     Methoden     isoliert werden kann.    <I>Beispiel:</I>    33,5 kg     bloiioäthylmetanilsaiires    Natrium  werden in 200 Liter Wasser gelöst und bei  <B>700</B> unter Rühren nacheinander mit 11 kg  Soda und 45 kg     benzylclilorid-p-sulfosaui-em            -Natrium    versetzt. Wenn alles eingetragen ist,  wird während einer Viertelstunde gekocht,  wobei die     Unisetzung    quantitativ vor sich  geht.

    Method <SEP> for the <SEP> production <SEP> of <SEP> ethylbenzylaniline-3,4'-dihulfonic acid. It has been found that ethylbenzylariline-3,4'-disulfonic acid can be obtained in a technically advantageous manner by condensation of 1 Dlol. benzylchloride-p-sulfosaureni sodium with 1 mol. Monoätbvlmetanilicäure in aqueous solution can represent.

   A solution is obtained which can readily be used for the preparation of dyes, or from which the Äthylbeiizylaiiilin- 3 # 4'-disulfonic acid can be isolated by known methods. <I> Example: </I> 33.5 kg of bloiioäthylmetanilsaiires sodium are dissolved in 200 liters of water and at <B> 700 </B> with stirring in succession with 11 kg of soda and 45 kg of benzyl chloride-p-sulfosaui-em-sodium offset. When everything has been entered, it is cooked for a quarter of an hour, the unisposition being done quantitatively.
