Description

Entwicklungssalze. Zusatz zum Patent 421837. In dem Hauptpatent 421837 sind Entwicklungssalze beschrieben, die aus wasserfreien Mischungen von mineralsauren Salzen diazotierbarer, nicht nitrierter und nicht sulfierter aromatischer Amine und salpetrigsatti-cti Salzen bestehen, denen gegebenenfalls noch saure Produkte oder auch indifferente Salze zugesetzt sind.Development salts. Addition to patent 421837. In main patent 421837 development salts are described, which are made from anhydrous mixtures of mineral acids Salts of diazotizable, non-nitrated and non-sulfated aromatic amines and nitrous satti-cti salts, which may contain acidic products or indifferent salts are added.

Es wurde nun gefunden, daß die mineralsauren Salze der nicht nitrierten und nicht sulfierten aromatischen Amine ganz oder teil-«-eise durch Salze aus beliebigen diazotierbaren Aminen und anderen Säuren als Mineralsäuren ersetzt werden können. Es kommen beispielsweise in Betracht Salze aus diazotierbaren aromatischen Aminen und Oxals iitire, Phthalsäure, aromatischen Sulfosäuren, wie Benzolsulfosäuren, Naphthalinsulfosäuren usw. Bei mehrbasischen Säuren können auch die sauren Salze Verwendung finden.It has now been found that the mineral acid salts of the non-nitrated and unsulfated aromatic amines wholly or partly - «- by salts of any diazotizable amines and acids other than mineral acids can be replaced. There are, for example, salts of diazotizable aromatic amines and oxalic acid, phthalic acid, aromatic sulfonic acids, such as benzenesulfonic acids, Naphthalene sulfonic acids, etc. In the case of polybasic acids, the acidic salts Find use.

Beispiel i.Example i.

Man mischt in möglichst wasserfreiem Zustande 18,3 Teile saures Anilinoxalat, So Teile Glaubersalz, 4,fi Teile Oxalsäure und 7 Teile \Tatriumnitrit. Beine Auflösen des Gemische in kaltem Wasser erhält man in kurzer Zeit eine gebrauchsfertige Diazolösung. Mitunter ist es bei Aminen, deren Salze leicht hydrolysiert «-erden, vorteilhaft, dein zum Auflösen dienenden Wasser noch geringe Mengen freier Mineralsäuren oder anderer Säuren zuzusetzen, da die Diazotierung dann rascher erfolgt. Enthält das Entwicklungssalz keinen Zusatz eines sauren Mittels, so ist ein Zusatz von Säure beim Auflösen des Salzgemisches in Wasser erforderlich. An Stelle der im Beispiel genannten Oxalsäure können auch andere saure Mittel, die salpetrige Säure aus ihren Salzen in Freiheit zu setzen vermögen, zugesetzt «-erden. Das N atriuninitrit kann auch durch andere Nitrite, z. B. Zink- oder Bariumnitrit, ersetzt werden.Mix 18.3 parts of acidic aniline oxalate in as anhydrous a state as possible, So parts Glauber's salt, 4, fi parts oxalic acid and 7 parts sodium nitrite. Dissolve legs of the mixture in cold water, a ready-to-use diazo solution is obtained in a short time. Sometimes it is advantageous with amines, the salts of which are easily hydrolyzed. your water used to dissolve still small amounts of free mineral acids or to add other acids, since the diazotization then takes place more quickly. Contains that Developing salt does not have the addition of an acidic agent, so is an addition of acid required when dissolving the salt mixture in water. Instead of the example called oxalic acid can also use other acidic agents that remove nitrous acid from their Able to set salts free, added «earth. The N atriuninitrite can also by other nitrites, e.g. B. zinc or barium nitrite, are replaced.

Beispiele. Man tnischt ähnlich wie in Beispiel i 3o,2 Teile saures I # 3-naplithalindisulfosaures p-N itranilin mit 62,6 Teilen 2 # 7-naplithalindisulfosaurem Natrium und 7,2 Teilen :\atriumnitrit. Beim Auflösen in Wasser, dem etwas Säure zugesetzt ist, erhält man in kurzer "Zeit eine gebrauchsfertige Diazolösung. Man kann dem Salzgemisch auch saure Verbindungen, z. B. Bisulfat, noch besonders zusetzen. An Stelle der sauren Salze kann man auch die neutralen Salze verwenden, z. B. Salze der Diisopropylnaphthalinsulfosäure usw.Examples. Similar to Example 13o, 2 parts of acid are mixed I # 3-naplithalindisulfosaures p-Nitraniline with 62.6 parts of 2 # 7-naplithalindisulfosaurem Sodium and 7.2 parts: \ atrium nitrite. When dissolving in water, the little acid is added, a ready-to-use diazo solution is obtained in a short time the salt mixture can also contain acidic compounds, e.g. B. bisulfate, still particularly add. At The neutral salts can also be used in place of the acidic salts, e.g. B. Salts of diisopropylnaphthalene sulfonic acid, etc.
