Zusatz zum Patent 235311 vom 12. Februar igio.*)Addition to patent 235311 from February 12 igio. *)
Patentiert im Deutschen Reiche vom 19. September 1911 ab. Längste Dauer: 11. Februar 1925.Patented in the German Empire on September 19, 1911. Longest duration: February 11, 1925.
Durch Patent 250086 ist ein Verfahren zur Darstellung von 2, 3-Dimethylbutadien (1, 3) geschützt, das darin besteht, daß man Pinakon mit sauer reagierenden neutralen Sulfaten destilliert.Patent 250086 describes a process for the preparation of 2, 3-dimethylbutadiene (1, 3) protected, which consists in the fact that you pinacon with acidic reacting neutral sulfates distilled.
Es wurde nun gefunden, daß man auch die sauer reagierenden neutralen Salze von Sulfosäuren mit Aminen vorteilhaft zu dieser Reaktion verwenden kann. Man braucht dabei nur ganz geringe Mengen eines solchen Salzes zu verwenden, da sie sich in heißem' Pinakon lösen.It has now been found that the acidic neutral salts of Sulphonic acids with amines can advantageously be used for this reaction. You need to use only very small amounts of such a salt, as it is in hot ' Loosen pinacon.
1000 Teile Pinakon werden mit 1 Teil naphtalinmonosulfosaurem Anilin versetzt und auf 130 bis 140 ° erhitzt. Es tritt eine lebhafte Reaktion ein, und es destilliert Pinakon, Wasser, etwas Pinakolin, der Hauptmenge nach aber ß-j'-Dimethylerythren über, das durch fraktionierte Destillation gereinigt wird! ·1000 parts of pinacon are mixed with 1 part of naphthalene monosulfonic acid Added aniline and heated to 130 to 140 °. There is a lively one Reaction, and pinacon, water, some pinacolin, the bulk of the distillation after but ß-j'-dimethylerythrene over that is purified by fractional distillation! ·
Verwendet man statt des genannten Salzes das Diphenylaminsalz der Naphtalin-i · 5 - disulfosäure oder andere der genannten Salze, so verläuft die Reaktion in derselben Weise.If the diphenylamine salt of naphthalene-i · 5-disulfonic acid is used instead of the salt mentioned or other of the salts mentioned, the reaction proceeds in the same way.
