Description

Verfahren zur Herstellung von stabilen Metallsolen Es hat sich gezeigt, daß bei der Herstellung von Metallsolen erst durch die kambinierte Verwendung von lysalbin- oder protalbinsauren Salzen einerseits und wasserlöslichen Oxaikylcellulosen oder ihren Derivaten andererseits ein Optimum an Haltbarkeit der Metallsole zu erzielen ist, während die Oxalkylcellulosen oder die lysalbin- bzw. protalbinsauren Salze für sich allein keine über lange Zeiträume hin anhaltende Stbilisie-. rungswirkung zeigen. Es gelingt hierdurch, zu Metallslen zu gelangen, welche noch nach 1 Jahr und länger haltbar sind Selbstverständlich müssen bei der Herstellung und Aufbewahrung dieser Metallsole die für diese Klasse erforderlichen Vorsichtsmaßregeln beachtet werden.Process for the production of stable metal brines It has been shown that in the production of metal brines only through the use of kambiniert lysalbinic or protalbinic acid salts on the one hand and water-soluble oxaikylcelluloses or their derivatives, on the other hand, to achieve optimum durability of the metal brine is, while the oxalkylcelluloses or the lysalbinic or protalbinic acid salts in and of itself no long-term stbilisia. effect demonstrate. This makes it possible to get metal beads that are still available after 1 year and have a longer shelf life, of course, during manufacture and storage of this metal brine, the precautionary measures required for this class are observed will.

Beispiele I. 2,75 ccm einer von freiem Ammoniak weitgehendst befreiten Wismut-Ammon- Citrat-Lösung mit einem Gehalt von 6 % Wismut werden unter Umriihren langsam in ein Gemisch von 25 ccm einer Lösung vcan 0,1% lysalbin- und 0,1% protalbinsaurem Natrium und 25 ccm einer Oxäthylmethylcelluloselösung von der Viscosität 3 eingetragen. Die Lösung wird bei 500 c in stickstoffatmosphäre und unter durchperlendem Stickstoff mit Glucose oder Natriumhydrosulfit oder Formaldehyd reduziert. Das entstandene Sol wird mit Alkohol-Äther gefällt und die Fällung in Wasser gelöst. Examples I. 2.75 cc of a freed ammonia as far as possible Bismuth-ammon-citrate solution with a content of 6% bismuth are stirred with stirring slowly into a mixture of 25 cc of a solution of 0.1% lysalbic acid and 0.1% protalbic acid Sodium and 25 cc of an oxethylmethylcellulose solution of viscosity 3 were entered. The solution is at 500 c in a nitrogen atmosphere and under nitrogen bubbling reduced with glucose or sodium hydrosulfite or formaldehyde. The resulting Sol is precipitated with alcohol-ether and the precipitate is dissolved in water.

2. 1,0g Silbernitrat wird in 3 ccm Wasser gelöst und im Überschuß mit einer 30 0/0igefl Lösung von Triäthanolamin versetzt und mit 25 ccm einer Oxäthylmethylcelluloselösung von der Viscosität I,25 und 25 ccm einer Lösung, die 0,1% lysalbin- und 0,1% protalbinsaures Natrium enthält, gemischt. Man erwärmt auf etwa a 70 C. Das entstandene Sol wird entweder durch Alkohol-Äther gefällt und nachher in Wasser wieder gelöst oder durch verdünnte Salzsäure gefällt, mit Wasser gewaschen und in schwach alkalischem Wasser wieder gelöst. 2. 1.0 g of silver nitrate is dissolved in 3 cc of water and in excess mixed with a 30% solution of triethanolamine and with 25 cc of an oxethylmethylcellulose solution of viscosity I, 25 and 25 ccm of a solution containing 0.1% lysalbic acid and 0.1% protalbic acid Contains sodium, mixed. It is heated to about a 70 C. The resulting sol is either precipitated by alcohol-ether and then dissolved again in water or by diluted hydrochloric acid precipitated, washed with water and soaked in weakly alkaline water solved again.
