Description
Verfahren zur Herstellung eines trockenen Diazopräparates. Es wurde gefunden, dass man ein trocke nes Diazopräparat erhält, wenn man ein in fester Form abgeschiedenes Diazosalz eines Chlortoluidins mit einer teilentwässerten Alu- rniniumsulfatverbindung, z. B. teilentwässer tem Alaun und teilentwässertem Aluminium sulfat mischt.
Als teilentwässerter Alaun ist dabei zweckmässig solcher anzuwenden, welcher bis zu \r/5 seines Kristallwassergehaltes ab gegeben hat. Als teilentwässertes Aluminium sulfat ist vorteilhaft solches anzuwenden, welches bis zu 3/4 seines Kristallwassers ab gegeben hat und etwa '/4 von diesem noch ent hält.
Eine derartig teilentwässerte Aluminium sulfatverbindung bindet das Wasser des mit ihr vermischten feuchten Diazosalzes rasch und dabei doch ohne gefährliche, zu hoch ansteigende Erhitzung und gestattet, ohne das bei Diazoverbindungen heikle Trocknen durch Wärme, rasch und vorteilhaft ein trockenes Diazosalzpräparat herzustellen. Man kann aber auch das aus einer Diazosalzlö- sung in fester Form abgeschiedene, bereits getrocknete Diazosalz mit der derartig teil entwässerten Aluminiumsulfatverbindung mi schen.
Das so erhaltene Diazopräparat ist völlig trocken, weist auch an der feuchten Luft eine grosse Beständigkeit auf und ist in kal tem oder wenig warmem Wasser schnell und gut löslich. Es kann noch mit wei teren Beimischungen und Färbereihilfskörpern versetzt werden.
Beispiel: 100 Teile feuchtes Chlorzinkdoppelsalz des dianotierten 4-Chlor-2-amino-l-toluols von 34 % Ohlortoluidingehalt werden mit 140 Tei- len teilentwässertem Alaun von zirka 145% Gehalt bezogen auf Mol. Gew. 949, gleich mässig vermahlen.
In gleicher Weise wird aus anderem festab geschiedenem Cblortoluoldiazosalz ein trocke nes Präparat erhalten.
Process for the production of a dry diazo preparation. It has been found that a dry Nes diazo preparation is obtained if a diazo salt, deposited in solid form, of a chlorotoluidine with a partially dehydrated aluminum sulfate compound, eg. B. partially dewatered system alum and partially dewatered aluminum sulfate mixes.
As a partially dehydrated alum it is advisable to use one which has given up to \ r / 5 of its water of crystallization. As a partially dehydrated aluminum sulfate, it is advantageous to use that which has given up to 3/4 of its water of crystallization and about 1/4 of this still holds ent.
Such a partially dehydrated aluminum sulfate compound binds the water of the damp diazo salt mixed with it quickly and at the same time without dangerous, excessively high heating and allows a dry diazo salt preparation to be produced quickly and advantageously without the diazo compound drying by heat, which is tricky with diazo compounds. But it is also possible to mix the already dried diazo salt deposited in solid form from a diazo salt solution with the aluminum sulfate compound which has been partially dehydrated in this way.
The diazo preparation obtained in this way is completely dry, is also highly resistant to moist air and is quickly and easily soluble in cold or slightly warm water. It can still be mixed with further additives and dyeing auxiliaries.
Example: 100 parts of the moist chlorzinc double salt of the dianotized 4-chloro-2-amino-1-toluene with a 34% ohlortoluidine content are ground evenly with 140 parts of partially dehydrated alum with a content of approximately 145% based on mol. Wt. 949.
In the same way, a dry preparation is obtained from other firmly separated cblortoluene diazosalt.
