Description

Gelatinierungs- und Weichmachungsmittel Es wurde gefunden, daß die höhermolekularen Nitroparaffine und ihre Abkömmlinge gute Gelatinierungs- und Weichmachungsmittel für Cellulosederivate darstellen. Die höhermolekul aren Nitroparaffine, die eine oder mehrere Nitrogruppen enthalten können, werden in bekannter Weise, zweckmäßig nach dem den Gegenstand des Patents 748977 bildenden Verfahren durch Einwirkung von Salpetersäure auf höhermolekulare Paraffinkohlenwasserstoffe mit gerader oder verzweigter Kette und mindestens 8, zweckmäßig wenigstens 12 Kohlenstoffatomen erhalten. Als Gelatinierungs- und Weichmachungsmittel sind außer den Nitroparaffinen auch deren Abkömmlinge, insbesondere Nitroparaffinalkohole und ihre Ester, gut geeignet. Die Nitroparaffinalkohole können durch Einwirkung aliphatischer Aldehyde auf die Nitroparaffine belispielsweise nach dem den Gegenstand des Patents 925 828 bildenden Verfahren erhalten und in bekannter Weise mittels ein- oder mehrbasischer Carbonsäuren bzw. mehrbasischer, anorganischer, sauerstoffhaltiger Säuren, wie Borsäure oder Phosphorsäure, in die entsprechenden Ester übergeführt werden. Die neuen Gelatinierungs- und Weichmachungsmittel sind mit den Cellulosederivaten ausgezeichnet verträglich und verleihen denselben hervorragende Elastizität und Kältebeständigkeit.Gelatinizing and softening agents It was found that the higher molecular weight nitroparaffins and their derivatives are good gelatinizing and softening agents for cellulose derivatives. The higher molecular weight nitroparaffins, the one or contain more nitro groups, are expedient in a known manner according to the process by action forming the subject of patent 748977 from nitric acid to higher molecular paraffin hydrocarbons with straight or branched chain and at least 8, advantageously at least 12 carbon atoms. In addition to nitroparaffins, there are also nitroparaffins as gelatinizing and softening agents their derivatives, in particular nitroparaffin alcohols and their esters, are well suited. The nitroparaffin alcohols can be caused by the action of aliphatic aldehydes on the Nitroparaffins, for example, according to that forming the subject of patent 925 828 Process obtained and in a known manner by means of mono- or polybasic carboxylic acids or polybasic, inorganic, oxygen-containing acids, such as boric acid or Phosphoric acid, can be converted into the corresponding ester. The new gelatinization and plasticizers have excellent compatibility with the cellulose derivatives and give them excellent elasticity and cold resistance.

Die Nitroparaffine oder ihre Abkömmlinge sind außerdem mit anderen hochpolymeren Stoffen gut verträglich, so daß man leicht Mischprodukte her- stellen kann, also beispielsweise aus Cellulosederivaten und Na;turharzen, natürlichem Kautschuk oder Eiweißkunstmassen.The nitro paraffins or their derivatives are also with others Highly polymeric substances well tolerated, so that mixed products can be easily place can, for example from cellulose derivatives and natural resins, natural rubber or protein art masses.

Beispiel 30 Gewichtsteile Nitrocellulose (niedrigviskos) (2 : 1 Spritz werden in 30 Gewichtsteilen Butylacetat -(IooO/oig), 5 Gewichtsteilen Butanol, 10 Gewichtsteilen Toluol, Io Gewichtsteilen Xylol gelöst und der Lösung 15 Gewichtsteile Nitroparaffin zugegeben. Es entsteht ein Lack, der einen elastischen und chemisch sehr widerstandsfähigen Film hinterläßt. Example 30 parts by weight of nitrocellulose (low viscosity) (2: 1 spray are in 30 parts by weight of butyl acetate (IooO / oig), 5 parts by weight of butanol, 10 Parts by weight of toluene, 10 parts by weight of xylene dissolved and the solution 15 parts by weight Nitroparaffin added. The result is a varnish that is elastic and chemical leaves a very resistant film.
