Definitions
- the present invention relates to the preparation of 1,3-disubstituted imidazolidin-2-ones, from 1,3-dioxalan-2-one (ethylene carbonate) and primary amines.
- 1,3-disubstituted imidazolidin-2-ones are interesting polar, non-protic solvents, in particular for high-molecular compounds such as polyamides, polyvinyl chloride, polyvinyl alcohol, polystyrene, polyurethane and phenolic resins . Furthermore, 1,3-disubstituted imidazolidin-2-ones are used as finishing agents in the textile industry.
- N, N'-disubstituted diamines with urea (EP 198 345), which must be carried out in solvent, or with the toxicologically questionable phos gene (EP 183 076) are also known. Also described are the syntheses from carbon dioxide, primary amine and ethylene glycol (JP 5 9155-364-A) or dichloroethane and the Leukart-Wallach reaction for the synthesis of 1,3-dimethylimidazolidinone, which requires a heterogeneous hydrogenation catalyst (GB 1517820 ; DE 1545614; US 2,422,400). The object of the invention was to develop a synthetic route for 1,3-disubstituted imidazolidin-2-ones which is simple and economical. In particular, the method is said to be superior to known synthetic routes from an environmental point of view.
- radicals R which may be the same or different, a) hydrogen; b) straight-chain, branched or cyclic alkyl radicals with 1 to 12 C atoms, which in turn contain C 6 . 10 aryl, Fl, Cl, Br can be substituted; c) aryl residues with 6 to 10 carbon atoms, which in turn can be substituted with C ⁇ - alkyl; d) heteroalkyl radicals in which the alkyl radicals as defined above are interrupted by one or more heteroatoms selected from O, S and N, e) heteroaryl radicals having 5 to 10 ring atoms and containing 1 to 3 heteroatoms selected from O, S, N,
- a preferred process product is 1,3-dimethylimidazolidin-2-one.
- the reaction is generally carried out at 150 ° C. to 300 ° C., preferably at 200 ° C. to 250 ° C., particularly preferably under autogenous pressure.
- the intrinsic pressure that is established is usually between 50 and 150 bar.
- the amount of primary amine used with respect to ethylene carbonate is advantageously stoichiometric or superstoichiometric, e.g. 5 times stoichiometric, preferably in the range of a 1.5 to 3 times stoichiometric excess.
- reaction time of up to about 24 hours has often proven to be sufficient.
- the yield of the process can generally be increased using water.
- the amount of water used can be up to 50% by weight. advantageously 30 to 45% by weight, based on the ethylene carbonate used. be.
- the reaction mixture can be worked up by simple distillation of the raw product.
- Example 2 The same batch as in Example 1 was heated at 250 ° C. for 24 hours without water. The subsequent work-up gave 476 g of 1,3-dimethyl-imidazolidin-2-one (75% yield).
- Example 5 Ethylene carbonate and methylamine were reacted and worked up as in Example 3, but at 200 ° C. The yield was 42%.
- Example 5 Ethylene carbonate and methylamine were reacted and worked up as in Example 3, but at 200 ° C. The yield was 42%.
