Abstract
Description
Foreliggende oppfinnelse angår en blanding basert på metylenklorid, og den omfatter videre en fremgangsmåte for avfetting av metaller under anvendelse av denne blanding. The present invention relates to a mixture based on methylene chloride, and it further comprises a method for degreasing metals using this mixture.
Klorerte hydrokarboner er de hyppigst benyttede midler for avfetting av metaller, tekstiler, keramer og glass på grunn av deres oppløsningsevne, deres ubrennbarhet og deres relativt lave kokepunkt. Chlorinated hydrocarbons are the most frequently used agents for degreasing metals, textiles, ceramics and glass due to their solubility, their inflammability and their relatively low boiling point.
Metylenklorid er spesielt stabilt mot oksydasjon, hydrolyse og pyrolyse. Forbindelsen bidrar ikke i noen fotokjemisk reaksjon. Det lave kokepunkt tillater anvendelse ved lave temperaturer. Alle disse prinsippielle egenskaper gjør forbindelsen til et utvalgt oppløsningsmiddel for avfetting av metaller. Methylene chloride is particularly stable against oxidation, hydrolysis and pyrolysis. The compound does not contribute to any photochemical reaction. The low boiling point allows use at low temperatures. All these fundamental properties make the compound a solvent of choice for degreasing metals.
Under denne operasjon kan imidlertid forbindelsen reagere med aromatiske forbindelser som innføres under bearbeiding av lettmetaller. During this operation, however, the compound may react with aromatic compounds introduced during the processing of light metals.
I henhold til en Friedel-Craftreaksjonsmekanisme har man dog dannelse av salter fra tyngre forbindelser som forurenser metylenklorid. Det er således en eksplosjonsfare på grunn av dekomponering, med derav resulterende dannelse av klorerte syrer, fosgen og saltsyre klorhydrid. According to a Friedel-Craft reaction mechanism, salts are formed from heavier compounds that contaminate methylene chloride. There is thus an explosion hazard due to decomposition, with the resulting formation of chlorinated acids, phosgene and hydrochloric acid chloride.
For å bøte på disse mangler er det nødvendig til metylen-kloridet å sette små mengder organiske produkter som gjør at man kan unngå denne reaksjon: det vil si å stabilisere det. In order to remedy these deficiencies, it is necessary to add small quantities of organic products to the methylene chloride which enable this reaction to be avoided: that is, to stabilize it.
Allerede foreslåtte metylenkloridpreparater som er stabilisert. US-PS 3 887 628 beskriver metylenklorid inneholdende 0,05 til 2% butylenoksyd og propylenoksyd; US-PS 3 923 912 beskriver metylenklorid inneholdende 0,05 - 2% aceton eller metyletylketon eller eventuelt propylenoksyd; US-PS 4 108 910 beskriver metylenklorid inneholdende et epoksyd og en alifatisk monoeter og EP-PS 0011 658 beskriver metylenklorid stabilisert med et etyl- eller metylformiat. Already proposed methylene chloride preparations which are stabilized. US-PS 3,887,628 describes methylene chloride containing 0.05 to 2% butylene oxide and propylene oxide; US-PS 3 923 912 describes methylene chloride containing 0.05 - 2% acetone or methyl ethyl ketone or optionally propylene oxide; US-PS 4 108 910 describes methylene chloride containing an epoxide and an aliphatic monoether and EP-PS 0011 658 describes methylene chloride stabilized with an ethyl or methyl formate.
Et mål ved foreliggende oppfinnelse er således å foreslå en blanding som kan benyttes for avfetting av metaller og som er stabil i nærvær av lettmetaller som aluminium og legeringer derav. An aim of the present invention is thus to propose a mixture which can be used for degreasing metals and which is stable in the presence of light metals such as aluminum and alloys thereof.
I henhold til dette angår foreliggende oppfinnelse en blanding, basert på metylenklorid og omfattende minst et stabilseringsmiddel, for avfetting av metaller, og blandingen karakteriseres ved at den som stabiliseringsmidler inneholder : According to this, the present invention relates to a mixture, based on methylene chloride and comprising at least one stabilizer, for degreasing metals, and the mixture is characterized by the fact that it contains as stabilizers:
a) propylenoksyd eller butylenoksyd, a) propylene oxide or butylene oxide,
b) aceton, og b) acetone, and
c) tetrahydrofuran, c) tetrahydrofuran,
idet hver av disse forbindelser a), b) og c) utgjør mellom with each of these compounds a), b) and c) constituting between
0,05 og 5 vekt-# av den totale vekt av blandingen. 0.05 and 5 wt-# of the total weight of the mixture.
Den totale mengde av epoksydet a) som benyttes kan ligge mellom 0,05 og 5 vekt-# av den totale masse av blandingen og ligger fortrinnsvis mellom 0,2 og 2%. Propylenoksyd er fore-trukket . The total amount of the epoxide a) used can be between 0.05 and 5% by weight of the total mass of the mixture and is preferably between 0.2 and 2%. Propylene oxide is preferred.
Den totale mengde aceton b) kan ligge mellom 0,05 og 5 vekt-# av den totale masse av blandingen og ligger fortrinnsvis mellom 0,2 og 2%. The total amount of acetone b) can be between 0.05 and 5% by weight of the total mass of the mixture and is preferably between 0.2 and 2%.
Den totale mengde av tetrahydrofuran c) kan ligge mellom 0,05 og 5 vekt-# av den totale masse av blandingen og ligger fortrinnsvis mellom 0,2 og 2%. The total amount of tetrahydrofuran c) can be between 0.05 and 5% by weight of the total mass of the mixture and is preferably between 0.2 and 2%.
Blandingen ifølge oppfinnelsen fremstilles ved enkel blanding av produktene med metylenklorid. Blandingen kan skje ved omgivelsestemperatur og mere spesielt mellom 5 og 30°C. Foreliggende oppfinnelse angår også en fremgangsmåte for avfetting av metaller ved hjelp av oppfinnelsens blanding. Åvfettingen kan skje i dampfase eller i væskefase i henhold til konvensjonelle driftsmetoder. The mixture according to the invention is prepared by simply mixing the products with methylene chloride. The mixing can take place at ambient temperature and more particularly between 5 and 30°C. The present invention also relates to a method for degreasing metals using the mixture of the invention. The degreasing can take place in the vapor phase or in the liquid phase according to conventional operating methods.
Eksempel: Example:
Man fremstiller en blanding med formelen (i vekt-#): A mixture is prepared with the formula (in weight #):
- metylenklorid 98 - methylene chloride 98
- propylenoksyd 0,5 - propylene oxide 0.5
- aceton 1 - acetone 1
- tetrahydrofuran 0,5 - tetrahydrofuran 0.5
Denne blanding tilfredsstiller kravene i henhold til BÅM (Bundesanstalt fur Materialprufung, Forbundsrepublikken Tyskland). This mixture meets the requirements according to BÅM (Bundesanstalt fur Materialprufung, Federal Republic of Germany).
Man skal her påpeke de fire trinn i BAM-prøven som er følgende: 1) Til 100 ml blanding settes 100 ml toluen, 0,7 g A1C13, 18 g aluminiumflak. Blandingen holdes under tilbakeløp i Here the four steps in the BAM test should be pointed out, which are as follows: 1) To 100 ml of mixture add 100 ml of toluene, 0.7 g of A1C13, 18 g of aluminum flakes. The mixture is kept under reflux i
18 timer i et bad som holder 58°C, 18 hours in a bath that holds 58°C,
2) Til blanding 1) settes 1 g sinkstearat med derpå følgende tilbakeløpskoking i 18 timer, 3) Til blanding 1) settes 10 ml oljesyre med derpå følgende tilbakeløpskoking i 18 timer, 4) Destillasjon av 300 ml av blandingen i tre fraksjoner på 100 ml og derefter prøve 1) på hver av de tre fraksjoner. 2) To mixture 1) add 1 g of zinc stearate followed by reflux for 18 hours, 3) To mixture 1) add 10 ml of oleic acid followed by reflux for 18 hours, 4) Distillation of 300 ml of the mixture into three fractions of 100 ml and then try 1) on each of the three fractions.
En formel kan godtas i henhold til BAM hvis den ikke gir noen reaksjon under disse prøver. A formula can be accepted according to BAM if it does not give any reaction during these tests.
