The present invention relates to a method for preparing N-glycidyl compounds, more particularly aromatic N-glycidyl amines, especially compounds which are epoxide resins having one or more glycidyl groups per molecule on average, and N-glycidyl compounds prepared by this method. - Concerning glycidylamine. Epoxide resins are used in industry as adhesives, paints, castings, insulators, and in reinforced composite materials, and a variety of epoxy resins with different chemical properties are commercially available. Such resins are usually glycidyl ethers or esters derived from epichlorohydrin and bisphenols or dicarboxylic acids, but aromatic The use of materials having a glycidyl group attached to a group amine nitrogen atom is often preferred. Such materials contain aromatic amines with approximately the same ratio of epichlorohydrin to amino hydrogen atoms.
It can be produced by reacting with 0.8 to 10 equivalents, followed by conventional dehydrochlorination using an alkali. This reaction may be carried out without a catalyst or in the presence of an acid catalyst as described in GB 2111977. Despite their useful properties, N-glycidylamines as prepared by conventional methods leave room for improvement in two respects. First, the epoxide content of the resulting products approaches the theoretical value for complete glycidylation, i.e., the value that would be observed if all amino hydrogen atoms were replaced by glycidyl groups. This is rare. The actual epoxide group content will vary depending on the nature of the amine and the presence or absence of other substituents in the molecule.
For example, the epoxide equivalent for commercially available glycidylated bis(4-aminophenyl)methane is given by Kirk-Othmer's Encyclopedia of Chemical Technology, 3rd edition, Vol. 9, p. 277. 117 to 133.
This corresponds to 79 to 90% of the theoretically possible epoxide content. The properties of the cured resin vary according to the epoxide content of the uncured resin: the greater the epoxide content, the greater the degree of crosslinking will be, and as a result the greater the strength of the cured resin. Will.
It is therefore clear that a higher epoxide content in the resin would be advantageous. A second disadvantage of N-glycidylamines as prepared by conventional methods is believed to be due to side reactions (coupling reactions occurring) occurring during the synthesis that exceed the desired glycidylation. is often very viscous. This also explains why such coupling or low epoxide contents are obtained. Viscous resins have more difficulties for use, especially in the production of fiber-reinforced composites or cast articles, so the use of reactive or inert diluents is often necessary to reduce this viscosity. be. Mixing diluents is generally considered undesirable.
A reactive diluent is one that reacts with the curing agent and remains in the cured resin. These tend to have an adverse effect on the properties of the resin being cured. Inert diluents are removed by evaporation before curing, and these often pose a flammable or toxic hazard. Furthermore, if they are not completely removed from the resin, they also have an adverse effect on the properties of the cured resin. The present inventors have demonstrated that N-glycidylation of aromatic amines can be performed using divalent or more polyvalent metal salts of inorganic oxygen acids.
more particularly by metal nitrates or metal perchlorates, or by divalent or more polyvalent salts of carboxylic or sulfonic acids containing halogen atoms, and even more especially for carboxylic or sulfonic acid groups. When catalyzed by salts of acids such as those substituted by one or more halogen atoms on the carbon atoms in This is what we have discovered that can be achieved. A further surprising advantage of the process of the invention is that aromatic amines whose amino groups are sterically hindered by other groups on the molecule can be N-glycidylated relatively easily, and thus epoxide resins can be produced. The aim is to widen the range of aromatic amines available. As described in the above-mentioned GB 2111977, as a description of the disadvantages of the process for the preparation of N-glycidylamine using known catalysts,
In N-glycidylation using trifluoromethanesulfonic acid as a catalyst, the yield of N-glycidylamine with low epoxide content and high viscosity is relatively low. The use of metal salts of inorganic oxygen acids as accelerators for the curing of epoxide resins with amines is known. GB 1464045 describes (a) an epoxide resin, (b) an aromatic or cycloaliphatic polyamine, and (c) magnesium, calcium, zinc,
Curable compositions comprising perchlorates of manganese, cobalt or nickel are disclosed. British Patent No. 1521356 describes (a) an epoxide resin;
(b) an aromatic amino compound; and (c) a curable composition comprising magnesium or a nitrate of a divalent or higher valent metal of group b, b, B, B, B, B or groups of the periodic table. There is. It is known to use metal salts of halogenated carboxylic and sulfonic acids as accelerators for curing epoxide resins with amines. GB 1498542 discloses that at least two halogen atoms selected from a) in particular polyamines or polyaminoamides, b) fluorine and chlorine atoms, or salts thereof, are added on the carbon atom adjacent to the carboxyl group. aliphatic or araliphatic having 2 to 8 carbon atoms;
Compositions suitable for use as curing agents for epoxide resins comprising monocarboxylic acids are disclosed. Preferred metals for metal salts used in compositions containing aromatic amines are lithium, sodium, calcium and magnesium. British Patent No. 1500206 discloses that a) aromatic,
A composition is disclosed that is suitable for use as a curing agent for an epoxide resin comprising a heterocyclic or cycloaliphatic polyamine, and b) a salt of trifluoromethanesulfonic acid. Preferred salts are lithium, calcium, zinc, cadmium, cobalt, nickel, manganese and magnesium salts. Despite their use as accelerators for the curing of epoxide resins, so far inorganic oxyacids or metal salts of halogenated carboxylic or sulfonic acids have failed in the production of N-glycidyl group-containing epoxy resins. It was not known that it could be used to catalyze or that the resins so produced would have superior properties. Therefore, one feature of the present invention is that (a) nitric acid or perchloric acid, or (b) fluorine, chlorine or bromine on the carbon atom alpha to the carboxylic or sulfonic acid group. with at least 0.7 equivalents of epichlorohydrin based on the amino hydrogen equivalent of the aromatic amine, and preferably from 0.8 to aromatic N consisting of heating an amine having at least one and preferably at least two aromatic amino hydrogen atoms in 1.5 equivalents and dehydrochloridizing the product.
- A method for producing glycidylamine. Another feature of the invention includes aromatic N-glycidylamines obtained by this method. The nitrates and perchlorates used as catalysts in this new process are preferably nitrates and perchlorates such as those described in Lange, Handbook of Chemistry, McGraw-Hill Publishing, 12th Edition. Nitrates and perchlorates of metals from groups A, B, B, B or groups of the periodic table. Magnesium, calcium, zinc, manganese, nickel, lanthanum, vanadium (as vanadyl),
itterbium, and uranium (as uranyl)
The nitrates and perchlorates of are particularly preferred. In the salts of halogen-substituted carboxylic and sulfonic acids used as catalysts, the anions are preferably derived from acids having at most 4 carbon atoms. Particularly preferred are the salts of trifluoroacetic acid, trifluoromethanesulfonic acid, trichloroacetic acid, 2,2-dichloropropionic acid and tribromoacetic acid. Carboxylic or sulfonic acid cations substituted by fluorine, chlorine or bromine atoms are preferably used as described in Lange's Handbook of Chemistry.
It is a cation of metals and transition metals of Group A of the Periodic Table of the Elements as described in the 12th edition published by McGraw-Hill. Particularly preferred cations are the iron, zinc, cadmium and lanthanum cations and most particularly the magnesium, vanadium (as vanadyl), manganese, cobalt and nickel cations. Certain preferred salts as catalysts in the process of the invention are magnesium perchlorate, calcium perchlorate, zinc perchlorate, nickel perchlorate, magnesium nitrate, manganese nitrate, lanthanum nitrate, ytterbium nitrate, launyl nitrate, trifluoro These are magnesium acetate, manganese trifluoroacetate, nickel trifluoroacetate, vanadyl trifluoroacetate, magnesium trifluoromethanesulfonate, cobalt trifluoromethanesulfonate, magnesium trichloroacetate, magnesium 2,2-dichloropropionate, and magnesium tribromoacetate. The amount of salt present in the reaction mixture is generally from 0.1 to 10 parts per 100 parts by weight of aromatic amine, particularly preferably from 0.4 to 2 parts per 100 parts by weight of amine. Aromatic amines glycidylated according to the present invention can be only primary amines, only secondary amines, or can have both primary and secondary amino groups attached directly to the aromatic ring. and it can also have one or more aromatic rings. Further groups which can be present in such aromatic rings are alkyl groups, especially those having 1 to 4 carbon atoms, C1 to 4 alkylene groups, sulfonyl groups, halogen atoms, hydroxyl groups, 1 to 4 carbon atoms, and 1 to 4 carbon atoms.
to 4 alkoxy groups, and tertiary amino groups. Preferred amines used in this method have one or two primary amino groups. Aniline, aminophenyl indane and the following formula or: (In the above formulas, R 1 , R 2 , R 3 and R 4 are the same or different and represent an alkyl group having 1 to 4 carbon atoms or a hydrogen atom, and X is a valence bond, a carbon An amine represented by an alkylene group having 1 to 4 atoms, an oxygen atom, a sulfur atom, a carbonyl group or a sulfonyl group is particularly preferred. Examples of particularly preferred amines include aniline,
1,3,3-trimethyl-1-(4-aminophenyl)-5-aminoindan, 1,3,3-trimethyl-1-(4-aminophenyl)-6-aminoindan, O-, m-, or p -phenylenediamine, 2,4-diethyl-6-methyl-1,3
-phenylenediamine, bis(4-aminophenyl)methane, bis(4-aminophenyl)-ketone, bis(4-aminophenyl) ether, bis(4-aminophenyl) sulfide, bis(3-
aminophenyl) and bis(4-aminophenyl)sulfone, 4,4'-diamino-3-ethyldiphenylmethane and bis(4-amino-3-ethylphenyl)-methane. The catalyst is an inert organic solvent such as 2-methoxyethanol, isodecanol, ethylene glycol,
diethylene glycol, N-methylpyrrolidone,
γ-Butyrolactone, benzyl alcohol, dibutyl phthalate, butane-1,4-diol, ethyl methyl ketone, benzene or toluene is best mixed into the reaction mixture. The reaction is usually carried out in an inert solvent, such as one or more of the solvents mentioned above, at elevated temperature, especially from 50 to 100°C. Epichlorohydrin and catalyst may be added simply or dropwise, if desired. When the reaction between the amine and epichlorohydrin is judged to be complete, usually within 1 to 5 hours, the dehydrochlorination is carried out by adding water, optionally together with a quaternary ammonium halide, such as benzyltrimethylammonium chloride, as a catalyst. This is carried out in a conventional manner by adding sodium oxide or potassium hydroxide.
After heating at 50 to 100°C for 2 to 10 hours, the mixture is washed with water and the organic layer is separated and washed with N.
- Obtain glycidylamine. It is used as prepared or after purification by conventional means. The N-glycidyl group-containing epoxide resin produced by the method of the present invention may be cured by conventional methods. The invention therefore includes products, such as castings or fiber-reinforced materials, made of the material obtained by curing the epoxide resin produced by the method of the invention. Suitable curing agents for epoxide resins containing N-glycidyl groups are known:
They include dicyandiamide, aromatic amines such as bis(3-aminophenyl) sulfone and bis(4-aminophenyl) sulfone and bis(4-aminophenyl) sulfone.
aminophenyl)methane (usually together with a promoter such as a BF3 -amine complex), and polycarboxylic anhydrides such as cyclohexane 1,2-dicarboxylic anhydride, methylbicyclo[2,2,1]-hept- 5-ene-2,3-dicarboxylic anhydride,
Includes pyromellitic dianhydride and benzophenonetetracarboxylic dianhydride. The following examples illustrate the invention in detail. All parts and percentages are by weight. Example 1 Bis(4-aminophenyl)methane (100g),
Toluene (100 ml) and 50% magnesium perchlorate (1 g) dissolved in 2-methoxyethanol are stirred and heated to 60°C. Add epichlorohydrin (203.5 g) little by little over 2 hours,
Maintain temperature between â and 90â. Once the addition is complete, the mixture is maintained at 80°C for an additional hour. The mixture was allowed to cool to 75°C, and 50% aqueous benzyltrimethylammonium chloride solution (6 g) was added.
Process with. Flaked sodium hydroxide (89
g) in portions over 2 hours and then heat the mixture at 75° C. for 3 hours. Next, water (300ml)
