Description
Verfahren zum Erhitzen von organischen Stoffen, insbesondere Kampfer.Process for heating organic substances, especially camphor.
Beim Kochen oder Schmelzen organischer Körper, bei denen es erforderlich ist, die Temperatur nicht iiber ein bestimmtes Maß ansteigen zu lassen, bedient man sich eines Sandbades, das auf über 2000 erhitzt wird. When cooking or melting organic bodies where necessary is not to let the temperature rise above a certain level take a sand bath heated to over 2000.
Bei der Benutzung eines derartigen Sandbades kommt es bisweilen vor, Idaß leicht entzündbare Stoffe in das Bad gelangen, wodurch glimmen, de Aschenteile auftreten, die bei zufälligen Anwesenheit von pflanzlichen oder tierischen Faserstoffen, insbesondere wenn dies durch lebhafte Luftbewegung begünstigt wird, in Brand geraten und somit eine große Feuersgefahr oder Explosionsgefahr entsteht.When using such a sand bath it sometimes happens That easily flammable substances get into the bathroom, causing smoldering parts of the ash occur in the accidental presence of vegetable or animal fibers, catch fire, especially if this is encouraged by brisk air movement and thus there is a great risk of fire or explosion.
Ganz besonders liegt diese Gefahr bei der Raffixation von Kampfer vor, der in Glasflaschen der Einwirkung des aus Kieselgur bestehenden Sandbades ausgesetzt wird, um zum Kochen oder auch anschließendem Sublimieren gebracht zu werden. Tritt infolge von Undichtigkeiten der metallenen Apparate oder auch infolge eines Flaschenbruches flüssiger Kampfer in die Asche über, so erhitzt sich das Bad, das sonst eine Temperatur von 220 bis 2300 aufweist, sehr leicht bis zur schwachen Rotglut, wodurch sofort eineBrandgefahr entsteht.This danger lies particularly in the refixation of camphor before, in glass bottles, the action of the sand bath consisting of diatomite exposed in order to be brought to a boil or also to be sublimated will. Occurs as a result of leaks in the metal apparatus or as a result if liquid camphor is broken into the ashes, the bath heats up, which otherwise has a temperature of 220 to 2300, very light to weak Red heat, which immediately creates a fire hazard.
Dieser ß'belstand wird nach vorliegender Erfindung dadurch beseitigt, Idaß dem Sanldl>ade Borax zugesetzt wird. Es ist hierbei zu beachten, daß der Borax pulverisiert und vorerst durch Anwärmen soweit entwässert wind, daß von der im gewöhnlichen Borax enthaltenen Wassermenge nur 1/10 bis 1120 in dem so gewonnenen kalzinierten Borax -verbleibt. According to the present invention, this ß'belstand is eliminated by That borax is added to the Sanldl> ade. It should be noted that the Borax pulverized and initially dehydrated by heating to such an extent that the The amount of water contained in ordinary borax is only 1/10 to 1120 in that obtained in this way calcined borax remains.
Sein spezifisches Gewicht entspricht dann dem der Infusorienerde. Das Gemisch der Asche und des Boraxes verhindert wirkungsvoll das Auftreten eines Gluthendes. Schon bei einem Zusatz von 20 Prozent Borax hat das Sandbad adie Eigenschaft, daß es mit Kampfer gemischt erst bei 3800 erglühen kann, wodurch bei Betrieben der hier in Frage stehenden Art eine genügende Sicherheit vorhanden ist. Es empfiehlt sich ein Mischungsverhältnis von 3O Teilen Borax und 70 Teilen Kieselgur, wobei erst bei 500° ein Erglühen möglich wäre, was aber niemals vorkommt. Es wird also eine Sandbadfüllung erzielt, die in jeder Weise die Vorzüge Ider üblichen Kieselgurbäder aufweist, ohne jedoch, den Nachteil zu besitzen, bei Gegenwart von Kampfer oder anderen organischen Substanzen zum Glühen zu gelangen, 90 daß die Gefahr von Explosionen oder Entfiammungen vermieden wird.Its specific weight then corresponds to that of the infusor earth. The mixture of the ash and the borax effectively prevents the occurrence of one Glowing. With an addition of 20 percent borax, the sand bath a has the property that mixed with camphor it can only glow at 3800, which means that the There is sufficient security in the type in question here. It recommends a mixing ratio of 30 parts of borax and 70 parts of kieselguhr, where A glow would only be possible at 500 °, but this never happens. So it will A sand bath filling is achieved which in every way has the advantages of the usual kieselguhr baths has, however, without having the disadvantage, in the presence of camphor or other organic substances to glow, 90 that there is a risk of explosion or inflammation is avoided.
