Definitions
- the invention relates to a process for the preparation of biscyanoacrylates and their use in cyanoacrylate adhesives.
- a monofunctional cyanoacrylate is first blocked with dienes.
- the blocked monofunctional cyanoacrylate is saponified to free acid.
- the ester is then prepared from the corresponding acid chloride with a diol.
- the pure biscyanoacrylate is finally obtained after repeated recrystallization from benzene. This production route therefore comprises 5 stages and is therefore uneconomical.
- H 2 C C (CN) -C0-0-R 2 (II) wherein R 2 is a branched or unbranched alkyl radical having 1 to 6 carbon atoms, with diols of the general formula
- Rl is a branched or unbranched divalent alkane radical having 2 to 18 carbon atoms, which may also contain heteroatoms such as halogens and oxygen or aliphatic or aromatic rings, to give biscyanoacrylics of the general formula
- a starting product is monofunctional cyanoacrylic acid or its alkyl ester according to formula II.
- the alkyl radical is to be chosen so that the alcohol formed can be easily removed. The person skilled in the art is familiar with the possibilities suitable for this from the general transesterification reaction.
- the alcohol is preferably removed by distillation.
- R 2 is therefore a branched or unbranched alcohol residue with 1 to 6 carbon atoms, preferably with one or two carbon atoms.
- the monofunctional cyanoacrylic acid ester is stabilized as usual.
- the diols are dihydric primary or secondary alcohols, preferably primary alcohols.
- the hydroxyl groups can be in any position relative to one another, but preferably in the alpha / omega position.
- the diols contain 2 to 18 carbon atoms, preferably 4 to 12 carbon atoms. They can be linear, branched or cyclical.
- the aliphatic radical can also contain an aromatic group or, in addition to the hydrogen and carbon atoms, also heteroatoms, such as e.g. Chlorine or oxygen atoms, preferably in the form of polyethylene or polypropylene glycol units. The following may be mentioned as specific diols: hexanediol, octanediol, decanediol and dodecanediol.
- the cyanoacrylic acid ester is used in excess.
- the molar ratio of onofunctional cyanoacrylic acid esters to the diol is thus at least 2.0: 1.0, but preferably 2.5: 1.0, in particular 2.2: 1.0.
- the transesterification is catalyzed by strong acids, especially by sulfonic acids, preferably by aromatic sulfonic acids, e.g. p-toluenesulfonic acid. But naphthalenesulfonic acid and benzenesulfonic acid as well as acidic ion exchangers are also possible.
- the concentration of the transesterification catalyst should be between 1 and 20% by weight, based on the monofunctional cyanoacrylate.
- the transesterification takes place - as usual - in solution.
- Aromatics and halogenated hydrocarbons serve as solvents.
- the preferred solvent is toluene and xylene.
- the concentration of the solution is in the range from 10 to 50, preferably from 10 to 20%.
- the monohydric alcohol or water formed is removed in a known manner, preferably detached with the solvent.
- the transesterification turnover is checked e.g. based on NMR spectra. As usual, the reaction takes several hours. In the case of toluene as the solvent and p-toluenesulfonic acid as the catalyst, the reaction is complete after 10 to 15 hours, i.e. alcohol is no longer separated.
- the biscyanoacrylates obtained polymerize very quickly in the presence of bases. As with the monofunctional cyanoacrylates, traces of water are already sufficient. The result is a three-dimensionally cross-linked polymer with relatively good thermal properties.
- cyanoacrylate adhesives it is therefore preferably used in known cyanoacrylate adhesives in an amount of 1 to 50, preferably 2 to 10% by weight, based on the adhesive as a whole.
- the known cyanoacrylate adhesives contain 2-cyanoacrylate esters of the general formula as the main component
- H 2 C C (CN) -C0-0-R (IV).
- R is an alkyl, alkenyl, cycloalkyl, aryl, alkoxyalkyl, aralkyl or haloalkyl group, in particular a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso- Butyl, pentyl, hexyl, allyl, methallyl, crotyl, propargyl, cyclohexyl, benzyl, phenyl, cresyl, 2-chloroethyl, 3-chloropropyl, 2-chlorobutyl, trifluoroethyl , 2-methoxyethyl, 3-methoxybutyl and 2-ethoxyethyl group.
- cyanoacrylates are known to the adhesive specialist, cf. Ullmanns Encyclopaedia of Industrial Chemystry, vol. AI, p. 240, Verlag Chemie Weinheim (1985) as well as US-PS ' 3 254 111 and PS-PS 3 654 340.
- Preferred monomers are the allyl, methoxyethyl, ethoxyethyl, methyl -, Ethyl, propyl or butyl esters of 2-cyanoacrylic acid.
- the adhesive can contain additives, for example plasticizers, thickeners, stabilizers, activators, dyes, etc.
- additives for example plasticizers, thickeners, stabilizers, activators, dyes, etc.
- the new cyanoacrylate adhesive according to the invention is particularly suitable for bonds with high thermal requirements, for example for bonding electrical and electronic components.
