Definitions
- the invention relates to a process for the preparation of polymers with recurring succinyl units.
- PAA polyaspartic acid
- US-A 5 288 783 describes the production of PSI from maleic anhydride and ammonia at higher temperatures and the hydrolysis to PAA.
- DE-A 43 00 020 covers the production of polymers of aspartic acid by thermal condensation of half-amides of maleic acid, fumaric acid or of ammonium salts of half-amides. The reaction takes place at temperatures above the melting point of maleic anhydride with gaseous ammonia.
- the present invention relates to a process for the preparation of polymers with recurring succinyl units, characterized in that maleic acid anhydride, maleic acid and / or fumaric acid, optionally in the presence of
- Comonomers are reacted with condensed liquid ammonia and the reaction product obtained is polymerized and optionally hydrolyzed.
- the conversion of, for example, maleic anhydride into liquid ammonia can be carried out, boiling cooling by means of evaporating ammonia being able to be used as a simple and efficient method for temperature control.
- the polymers produced according to the invention preferably have recycle
- iminodissucinate units can preferably be contained in at least one of the following structures:
- the polymer produced preferably shows chain lengths or molecular weights according to gel permeation chromatography analyzes (Mw) of 500 to 10,000, preferably 500 to 5,000, particularly preferably 700 to 4,500. Based on the groups
- (recurring aspartic acid units) preferably have at least 50%, in particular at least 70%, ⁇ -linked.
- iminodisuccinate units are present, they can be randomly distributed in the polymer or preferably present as an end group. Based on the sum of all recurring units, the iminodisuccinate unit is present in a preferred embodiment in at least 0.1 mol%.
- the molar ratio of the iminodisuccinate units incorporated in the polymer to the sum of all monomer units incorporated in the polymer is preferably 0.1 mol% to 99 mol%, preferably 1 mol% to 50 mol%, particularly preferably 2 mol% to 25 Mole%.
- the starting materials can be used individually or in mixtures, in bulk or in solution.
- the polymers according to the invention can optionally be present as a free acid or as a salt, preferred salts are e.g. Alkali and
- maleic anhydride or its derivatives are used as a melt.
- the reaction of the starting materials can optionally be carried out in the presence of a colsolvent.
- a colsolvent lower alcohols, polar aprotic solvents such as dimethylformamide, N-alkylpyrrolidones, sulfolane, acetone, polyalkylene glycols, polyalkylene glycol monoalkyl ethers and polyalkylene glycol dialkyl ethers are suitable as cosolvents.
- Supercritical gases such as e.g. Carbon dioxide.
- the starting materials are molten maleic anhydride and ammonia.
- Molten maleic anhydride is preferably introduced into a reactor filled with liquid ammonia.
- the temperature of the maleic anhydride is 60 to 100 ° C.
- the reaction of the maleic anhydride preferably takes place at temperatures between 60 and 100 ° C and a pressure of 26 to 64 bar.
- the molar ratio of maleic anhydride and ammonia is preferably at least 1: 4, it is preferably 1: 4 to 1: 500.
- the excess of ammonia is of particular advantage since the reaction of the anhydride with the ammonia is a very fast and highly exothermic reaction. By evaporating ammonia, the heat of reaction can be easily dissipated without additional diluents. Due to the excess
- ammonia can form the ammonium salt of maleic acid.
- intermediate products such as maleic acid diammonium salt or maleic acid ammonium salt can be prepared from the starting materials mentioned above in a separate process step and then thermally polymerized batchwise or continuously in bulk or in suitable solvents.
- the invention therefore also relates to a process for the preparation of unpolymerized nitrogen compounds of a C, -carboxylic acid, characterized in that maleic anhydride, maleic acid and / or fumaric acid are reacted with condensed liquid ammonia to give a low molecular weight product.
- This can be, for example, an amide, imide or ammonium salt, in particular the mono- or diammonium salt of maleic acid, maleic acid, aspartic acid, iminodisuccinic acid, iminodisuccinamic acids or asparagine.
- the polymerization of the reaction product is generally carried out at temperatures between 100 ° C. and 350 ° C., preferably between 120 ° C. and 250 ° C., particularly preferably between 120 ° C. and 220 ° C.
- the residence time is preferably between 1 second and 600 minutes, preferably 5 seconds to 180 minutes, particularly preferably 10 seconds to 150 minutes. However, it can also be done differently, e.g. with microwaves.
- all apparatus are suitable for thermal polymerization which, with a narrow residence time distribution, permit the necessary minimum residence time for the polymerization and at the same time an at least partial evaporation of the solvent and of the water formed during the reaction.
- Preferred devices for thermal polymerization are therefore all apparatuses which have a defined residence time with a narrow residence time distribution for the solid or highly viscous phase and at the same time good temperature control by at least partial evaporation of the solvent (organic solvent and / or water) and / or enable the water of reaction formed in the polymerization.
- solvent organic solvent and / or water
- Such preferred devices can be, for example
- Suitable bases are alkali and alkaline earth metal hydroxides or carbonates such as sodium hydroxide solution, potassium hydroxide solution, sodium carbonate or potassium carbonate, ammonia and amines such as triethylamine, triethanolamine, diethylamine, diethanolamine, alkylamines etc.
- the temperature during the hydrolysis is preferably in a range including up to the boiling point of the suspension or solution containing succinyl groups and preferably at 20 to 150 ° C.
- the hydrolysis is optionally carried out under pressure.
- the hydrolysis is optionally carried out with the addition of a further monoethylenically unsaturated carboxylic acid derivative.
- a further monoethylenically unsaturated carboxylic acid derivative for example, maleic anhydride, maleic acid, citraconic acid, itaconic acid, aconitic acid, acrylic acid and fumaric acid are suitable.
- the amino groups of the N-terminal end of the polymer molecule can be added to the monoethylenically unsaturated carboxylic acid derivative present in the salt form.
- the primary polymerization products can also have ethylenically unsaturated end groups. It may therefore be useful to optionally add aminocarboxylic acids to the reaction mixture during the basic hydrolysis, e.g. Glycine, aspartic acid, lysine,
- Glutamic acid etc. for example also add ammonia.
- a grafting of the polymer end groups is achieved by this measure.
- the polymers are characterized by an improved calcium binding process. Furthermore, they show complexing properties compared to heavy metals such as copper, iron etc. They can be used as additives in phosphate-free and phosphate-free detergents and cleaning agents.
- the polymers are builders for detergents and reduce the incrustation and graying on the washed fabric during the washing process. Furthermore, the polymers according to the invention inhibit and delay the precipitation of salts, in particular crystals, for example calcium carbonate, calcium sulfate, calcium phosphate, barium sulfate and magnesium silicate, from aqueous solutions and are therefore suitable as water treatment agents. They can be added to the water in cooling circuits, evaporators or seawater desalination plants and pressurized water for secondary oil production and water treatment in mining. They can also be used as deposit inhibitors when evaporating sugar juice.
- the copolymers can also serve as stabilizers for bleaching agents such as hydrogen peroxide in bleaching processes.
- copolymers according to the invention are to be classified as biodegradable according to the "OECD Guidelines for testing of chemicals (1981)".
- Yield of the sodium salt of polyaspartic acid was 123 g.
- the weight average molecular weight determined by means of gel permeation chromatography was approx. 1750 g / mol, the ß fraction approx. 70%.
