Description

Bohrölemulsion In der metallverarbeitenden Industrie: werden beider Bearbeitung der Metalle. an Stelle von reinem Mineralöl sehr oft wässerige Mineralöleinttlsionen; sogenännte Bohröle; zur besseren . Kühlung verwendet. Diese Bohröle bestehen aus Mineralöl, dem fettsaure oder türkischrotölsaure Seifen oder andere organische Emulgatoren zugesetzt sind. Die Verdünnung mit Wasser wird in dem- Maße vorgenommen, däß der Ölgehalt der Emulsion noch eine genügende Schmier--#virkung gewährleistet. Solche wässeriger Ölemulsionen verursachen nun sehr oft bei der Verarbeitung von Metallteilen Rostbildung. Um diese Rostbildung zu verhüten, hat man 'bisher. oft den Ölgehalt der Emulsionen erhöht, d. , man arbeitete mit ölreicheren Emulsioften, als eigentlich für .die Schmierwirl-,ung erforderlich war. Diese Maßnahme war naturgemäß wenig wirtschaftlich...Drilling oil emulsion In the metalworking industry: both Processing of metals. instead of pure mineral oil, very often aqueous mineral oil inserts; so-called drilling oils; for better . Cooling used. These drilling oils consist of Mineral oil, fatty acid or Turkish red oil soaps or other organic emulsifiers are added. The dilution with water is carried out to the extent that the Oil content of the emulsion still guarantees a sufficient lubricating effect. Such aqueous oil emulsions cause very often in the processing of metal parts Rust formation. In order to prevent this rust formation, one has so far. often the oil content the emulsions increased, d. , one worked with more oil-rich emulsions than actually for. the lubricant, ung was required. Naturally, this measure was little economically...

Es ist bekannt, die korrodierende Wirkung der wässerigen Ölemulsionen dadurch zu beseitigen, daß man ihnen Nitrit; insbesondere in Form von Natriumnitrit, zusetzt. Diese Emulsionen haben aber den Nachteil, -daß sie selbst in geringer Konzentration; besonders nach längerer Standzeit, ztr Ölabscheidüng neigen.The corrosive effect of aqueous oil emulsions is known to eliminate them by giving them nitrite; especially in the form of sodium nitrite, clogs. However, these emulsions have the disadvantage that they are even in low concentrations; especially after long periods of standing, tend to cause oil separation.

Es wurde nun- gefunden, daß man zu'Bohrölen, die in vorzüglichem Maße die Rostbildung verhüten und. die Nachteile der bekannten Ölemulsionen nicht aufweisen, > gelangen. kann, wenn man den wässerigen Ölemulsionen wasserlösliche. Salze von Äthercarbonsäüren der - allgemeinen Formel (R # O #) X # R' # C O Q H zusetzt. In der allgemeinen Formel stellt R einen beliebigen organischen Rest mit wenigstens q. Kohlenstoffatomen dar, der durch Heteroatonme oder Heteroatomgrupped unterbrochen und auch cyclisch angeordnet sein kann, während R' ein Alkylenrest ist, der nach substituiert sein kann; und X die Zahlen T oder z bedeutet.It has now been found that to 'drilling oils which are excellent prevent rust formation and. do not have the disadvantages of the known oil emulsions, > arrive. can, if the aqueous oil emulsions are water-soluble. Salts of Ether carbonic acids of the general formula (R # O #) X # R '# C O Q H added. In of the general formula, R represents any organic radical with at least q. Carbon atoms, interrupted by heteroatoms or heteroatom groups and can also be arranged cyclically, while R 'is an alkylene radical following may be substituted; and X represents the numbers T or z.

Derartige Äthercarbonsäuren sjnd z. B. Butyloxyessigsäure, i-Amvloxyessigsäüre.

Unter diesen Äthercarbonsäüren haben die,Alkoxy-und Cycloalkoxvfettsäuren den Vorrang.Such ether carboxylic acids are e.g. B. butyloxyacetic acid, i-amvloxyacetic acid. Mixtures of alkoxyacetic acids obtained from mixtures of alcohols, which of the reduction of precursor acids Paraffin oxidation originate or as high-boiling fractions - incurred in the synthesis of methanol, Octyloxye @ setic acid, Dodecyl acetic acid ,,, alkoxy fatty acids, available from secondary all @ dhöle, the in turn from first run fatty acids with 7: to 9r carbon atoms by ketonization and subsequent hydrogenation are obtained by reaction with halogen fatty acids, 'Cyclohexyloxyacetic acid, _ Tetrahydrofurfuryloxy- "acetic acid, phenoxyacetic acid, Cresoxyacetic acid, essentially alkylated or cycloalkylated aryloxy fatty acids, naphthenyloxyacetic acids, Abietyloxyacetic acids, benzyloxyacetic acid, a-heptyloxypropionic acid, ß-octyloxypropionic acid, a.-Octyloxyisobutyric acid, a-Octyloxycapric acid,, etheric acids, obtainable from Alcoholates of the primary alcohols C, -C9 and o; -halo fatty acids C, -C9, a-butoxylauric acid, 6-oxy- or methoxy-n-liexyloxyacetic acid and the like among these ether carboxylic acids the alkoxy and cycloalkoxy fatty acids have priority.

Die wasserlöslichen Salze der Äthercarbonsäuren haben gegenüber Natriumnitrit den Vorteil, daß sie nicht nur die Beständig= keit der Emulsionen nicht beeinträchtigen, sondern vielmehr noch emulgierende M7irlcung aufweisen. -Beispiel Ein Bohröl von der Zusammensetzung 13 °/o Wasser, 64'/o Mineralöl -(leichtes Maschinenöl), 23 0l, Schmierseife wurde mit Leitungswasser in einem Ver- -hältnis i : 2o verdünnt und, dieser Einulsiön 0,25 bzw. ö,5 °1o Natriumsalz einer Äther-_ carbonsäure, hergestellt aus einer technischen Mischung primärer Alkohole mit 7 bis 9 C-Atomen durch Umsetzung mit Monochloressigsäure, zugesetzt.The water-soluble salts of the ether carboxylic acids have sodium nitrite the advantage that not only do they not impair the resistance of the emulsions, but rather still have an emulsifying effect. -Example A drilling oil from the composition 13% water, 64% mineral oil - (light machine oil), 23 0l, Soft soap was diluted with tap water in a ratio of i: 2o and, this Einulsiön 0.25 or 0.5 ° 1o sodium salt of an ether carboxylic acid, produced from a technical mixture of primary alcohols with 7 to 9 carbon atoms by reaction with monochloroacetic acid added.

In diese Emulsion wurden jeweils vorher entfettete Gußeisenstücke gelegt und die Emulsion' auftrocknen und die Stücke :`4ä Stunden trocken liegen gelassen.In each case, pieces of cast iron which had previously been degreased were placed in this emulsion and the emulsion 'dry up and the pieces:' lie dry for four hours calmly.

Die Gußeisenstücke aus der Bohrölemulsion mit einem Zusatz von 0,25 % äthercarbonsaurem Natrium zeigten noch vereinzelte Postflecken.The cast iron pieces from the drilling oil emulsion with an addition of 0.25% sodium ether carbonate still showed isolated mail stains.

Die Gußeisenstücke aus der Bohrölemulsion mit einem Zusatz von 0,5 % äthercarbonsaurem Natrium waren vollkommen rostfrei.The cast iron pieces from the drilling oil emulsion with an addition of 0.5 % sodium ether carbonate were completely rust-free.

Eine Entmischung der Emulsion selbst nach tagelangem Stehen trat nicht ein.The emulsion did not separate even after standing for days a.
