Abstract
The invention relates to (meth)acrylic acid copolymers comprising methacrylic acid units. The polymer is functionalised with aminoalkyl sulphonic acids. The invention also relates to a method for the production thereof and to the use thereof for treating water, preventing scale during the extraction of oil, and for preventing corrosion in aqueous systems.
Description
(methyl) acrylic copolymer that the present invention relates to the method for a kind of preparation (methyl) acrylic copolymer, obtains by this method and be used for water treatment, the preferred purposes in cooling and heat-processed and in oil production, suppress the purposes of fouling.
In oil production, because the precipitation of alkaline earth metal carbonate and sulfonate appears in mixing of temperature variation and oil-field water and injection water in the production process.They have stopped up the rock stratum hole and have accumulated in pipe surface, cause producing being difficult to carry out, even can not carry out sometimes.
In water treatment, in cooling or heat-processed (comprising sea water desalinization), or in heat transfer process, generally in cooling or heating medium, add respectively and can prevent or corrosion and sedimentary ingredients occur in the delay loop at least greatly.The ingredients of Shi Yonging comprises zinc salt, polyphosphate, phosphonate, polymkeric substance, microbicide and/or tensio-active agent as required for this reason.
In order to control protection against corrosion and the resistive connection dirt in the open cooling loop, there is difference in principle in two kinds of methods:
At first, phosphorous ingredients can be used for cooling and heating medium.Representative instance wherein is polyphosphate and phosphonate, 1-hydroxyl ethane-1 for example, and 1-di 2 ethylhexyl phosphonic acid (HEDP), 2-phosphoryl butane-1,2,4-tricarboxylic acid (GBTC) and Amino Trimethylene Phosphonic Acid (ATMP) are used with the form of its sodium salt separately.These phosphorous ingredients generally influence hardness stability.In addition, polyphosphate has improved corrosion-resisting function.
Perhaps as selection, zinc salt also can be used for cooling and heating medium, and in the case, wherein the zine ion of Cun Zaiing is mainly used in the protection iron and steel.
In some cases, also a spot of zinc salt is added in the phosphonate, so that protect employed iron and steel simultaneously outside hardness stability.The effect of these additives strengthens by suitable polymers:
Suitable polymers at first can strengthen the effect of phosphonate to hardness stability, and secondly, they can also stablize polyphosphate, especially when they add with high density.Prevented calcium phosphate precipitation like this.In addition, suitable polymers can also be stablized zn cpds, thereby can not occur deposition on the metallic surface, and the destruction to protective membrane therefore do not occur.Anticorrosive work is that example is passed through in the metallic surface the film forming fact and explained in order to phosphonate.This film is isolated iron and steel and cooling or heating medium.Formed film is made up of the phosphonate of most iron (II) and calcium ion and introducing.This film is extremely thin, makes stabilization must guarantee to prevent to break and the corrosive possibility occurs at each point.
Be applicable to and stablize phosphonate and phosphatic polymkeric substance can be known by prior art in principle.
Thereby for example, EP-A 0 244 584 has described the N-substituted acrylamide that for example carries sulfo group buserelin group and has been used to suppress industrial cooling loop and corrosion occurred.The acrylamide that these N-replace is by the transamidation preparation of polypropylene acid amides.N-substituted acrylamide according to EP-A 0 244 584 produces inhibition to phosphate anion, but phosphonium acid ion is not had restraining effect.
EP-B 0 330 876 has described on the structure and EP-A 0 244 584 similar N-substituted acrylamides.But desired as EP-B 0 330 876, the purposes of these N-substituted acrylamides relates to stablizes iron in water-based system, wherein do not disclose the definite degree of amidation of used N-substituted acrylamide.
US 4,801, and 388 polymkeric substance of having described by adding based on (methyl) vinylformic acid and sulfo group alkyl (methyl) acrylamide or methyl (acrylamide) suppress sedimentary method in water-based system.
US 4,604,431 described a kind of by comprising the acrylic or methacrylic acid groups polymkeric substance and the method for alkylsulphonic acid prepared in reaction acrylamide alkyl sulfonic acids under pressure and elevated temperature.
US 4,756, and 881 disclose and comprise the combination of acrylamido alkansulfonic acid and organophosphate and be used for suppressing the corrosive purposes at industrial colling.
The shortcoming of above-mentioned prior art polymers is that they precipitate under higher calcium concn.In addition, particularly unite under the situation of using phosphonium acid ion and zine ion in cooling or heating systems, such polymkeric substance is favourable: it plays a role simultaneously to stablize both modes of phosphate anion and zine ion.In addition, when using phosphate additive, and particularly when calcium ion exists with higher concentration, the polymkeric substance that can suppress calcium phosphate precipitation is favourable.At last, such polymkeric substance conforms with expectation, and it generally disperses with solid particulate, thereby has avoided them to deposit on the metallic surface of cooling or heating systems.The prior art polymkeric substance does not satisfy or has only satisfied deficiently these requirements.
Therefore, the purpose of this invention is to provide a kind of method for preparing polymkeric substance, this polymkeric substance is in cooling or heating circuit, in corresponding medium, strengthen the hardness stabilization of phosphonate and stablized polyphosphate simultaneously, thereby, for example, precipitation does not appear in the presence of calcium ion.And the polymkeric substance that obtains by the inventive method is used for stablizing zn cpds, so that they can not form deposition on the metallic surface of cooling or heating circuit.
According to the present invention, the method for preparation (methyl) acrylic copolymer of described purpose by comprising following processing step realizes:
(1) (methyl) vinylformic acid carries out radical polymerization, forms polymkeric substance I, and
(2) by making the polymkeric substance I amidation that forms by processing step (1) with at least a amidoalkanesulfonic acid reaction.
In the processing step (2) of the inventive method, the carboxylate radical of the polymkeric substance I that is formed by processing step (1) and the ratio of aminoalkyl group sulfonic acid are preferably 2:1-15:1, preferred especially 3:1-11:1, especially 4:1-8:1.
Processing step (1) preferably 100-200 ℃, preferred especially 105-135 ℃, especially carry out under 120-125 ℃.
Processing step (1) preferably carries out in closed reaction container such as autoclave.Therefore, the pressure of processing step (1) is generally determined by the vapour pressure (autogenous pressure) of used component under said temperature.Irrelevant with it, if suitable, can use the pressure of additional pressure or reduction.
Described monomeric radical polymerization is preferably using hydrogen peroxide as carrying out under the initiator.But,, can select to use all compounds that can under reaction conditions, form free radical, for example superoxide, hydroperoxide, sulfuric peroxide hydrochlorate, peroxidation dicarboxylic acid, peroxycarboxylic acid esters and/or azo-compound about initiators for polymerization.
If suitable, in the processing step (1) of the inventive method, can use other other monomer, for example can with the ethylene linkage unsaturated monomer of (methyl) acrylic acid copolymer.Suitable copolymers is a monoene key unsaturated carboxylic acid for example, as toxilic acid, fumaric acid, methylene-succinic acid, methylfumaric acid, methylene radical propanedioic acid and citraconic acid.But the monomer of other copolymerization is the C of monoene key unsaturated carboxylic acid
