Description

Verfahren zur Herstellung von glasklarem und lichtbeständigem Kunsthörn aus Casein Es ist bekannt, durchsichtiges Kunsthorn aus Casein durch Zusatz von organischen Verbindungen herzustellen. Am gebräuchlichsten ist der Zusatz von Methyldiphenylamin, das dem Casein vor der Verarbeitung zugesetzt wird. ebenso hat man bereits zu diesem Zweck Dimethylanilin, Äthylbenzylanilin, hydroaromatische oder aliphatischhydroaromatische Amine, alkylierte Carbazole usw. zugegeben.Process for the production of crystal clear and lightfast artificial horn from casein It is known that transparent synthetic horn can be made from casein by adding to produce organic compounds. The most common is the addition of methyldiphenylamine, which is added to the casein before processing. likewise one already has to this Purpose Dimethylaniline, ethylbenzylaniline, hydroaromatic or aliphatic hydroaromatic Amines, alkylated carbazoles, etc. added.

Es ist jedoch durch Vergleichsversuche festgestellt worden, daß keines dieser Aufhellungsmittel so wirksam ist wie das erfindungsgemäß zu verwendende Gemisch von alkylaralkylierten Anilinen und Dichlorhydrin. Das so hergestellte Kunsthorn ist glasklar und lichtbeständig und verändert sein Aussehen weder durch Einwirkung des Lichts noch durch Temperaturschwankungen. Beispiel ioo kg Labcasein werden angemischt mit 25 1 Wasser und 21 einer Lösung, die zwei Gewichtsteile Äthylbenzylanilin und ein Gewichtsteil Dichlorhydrin enthält. Selbstverständlich können dieser Mischung Farb- und Füllstoffe in beliebiger Weise zugesetzt werden. Das Casein wird dann in bekannter Weise zu Kunsthorn verarbeitet und im Formaldehydbad gehärtet.However, it has been found by comparative tests that none this lightening agent is as effective as the mixture to be used according to the invention of alkyl aralkylated anilines and dichlorohydrin. The artificial horn made in this way is crystal clear and lightfast and does not change its appearance through exposure to it of light due to temperature fluctuations. Example 100 kg of rennet casein are mixed with 25 l of water and 21 of a solution containing two parts by weight of ethylbenzylaniline and contains one part by weight of dichlorohydrin. Of course you can mix this Dyes and fillers can be added in any way. The casein will then Processed into synthetic horn in a known manner and hardened in a formaldehyde bath.
