Description

METHOD FOR PRODUCING PHOSPHORIC ACID ESTER AMIDES < RTI ID = 0.0 >

The present invention relates to a novel process for preparing phosphoric acid ester amides.

Phosphoric acid ester amides are used, for example, as flame retardants in molded products of synthetic resins and fiber products (see, for example, Patent Document 1).

For example, anilino diphenylphosphate, which is a representative example of phosphoric acid ester amides, can be usually obtained by a condensation reaction of diphenylphosphorochloridate and aniline, that is, a dehydrochlorination reaction.

In this reaction, when one equivalent of diphenylphosphorochloridate and aniline are used together, 0.5 equivalent of aniline is reacted with 0.5 equivalent of diphenylphosphorochloridate to produce the desired anilinodiphenylphosphate , And 0.5 equivalent of the remaining aniline acts as a hydrogen chloride capturing agent to form a hydrochloride salt, so 0.5 equivalent of diphenylphosphorochloridate remains unreacted.

Therefore, when anilinodiphenyl phosphate is produced by the reaction of diphenylphosphorochloridate and aniline, usually 2 equivalents of aniline is used per 1 equivalent of diphenylphosphorochloridate, of which aniline 1 equivalent of the aniline is reacted with 1 equivalent of diphenylphosphorochloridate, and 1 equivalent of the remaining aniline acts as a hydrogen chloride scavenger, thereby making effective use of diphenylphosphorochloridate in the reaction (see, for example, Patent Document 2).

However, in the production of anilino diphenyl phosphate, when 2 equivalents of aniline are used per 1 equivalent of diphenylphosphorochloridate and 1 equivalent of aniline is used as a hydrogen chloride capturing agent, anilino di The yield of phenyl phosphate is not more than 50% with respect to aniline. On the other hand, the step of neutralizing and purifying aniline hydrochloride after completion of the reaction is also troublesome, and therefore, the above method is economically disadvantageous in view of aniline .

Figure pct00001

Therefore, as a hydrogen chloride capturing agent, a heterocyclic aromatic amine compound such as pyridine or an aliphatic tertiary amine such as triethylamine is used instead of aniline (see, for example, Patent Document 3). However, these amines may not effectively function as a hydrogen chloride capturing agent in the case of aromatic amines. In addition, complicated steps are also required to recover and reuse amines from the hydrochloride salts after the completion of the reaction. In addition, according to this method, an odor caused by an amine used in an obtained anilinodiphenyl phosphate may remain.

According to the present invention, as described above, the phosphomonalohalidate is used as a phosphorus monohydrate by the dehydrohalogenation reaction, that is, condensation reaction with at least one amine compound selected from a monoamine compound and a diamine compound, The intended phosphoric acid ester amide can be obtained in accordance with the amine and the amine compound to be used.

Further, according to the present invention, as described above, phosphorodihalidate is used as a phosphohalidate, and this is subjected to a dehydrohalogenation reaction with a monoamine compound, that is, a condensation reaction, Corresponding to the monoamine compound to be used and the monoamine compound to be used, a desired phosphoric acid ester amide can be obtained.

In the reaction of these phosphorohalidates with amine compounds, according to the present invention, 0.5 equivalents or more, preferably 0.8 equivalents to 1.2 equivalents of the amine compound are added to the phosphorous halide at a temperature of 130 占 폚 or higher , The corresponding phosphoric acid ester amides can be obtained in a high yield relative to the amine compound.

In the present invention, one equivalent of phosphorodihalidates is a value obtained by dividing one mole of the phosphohalidate by the number of halogen atoms of the phosphorohalidate, and one equivalent of the amine compound is And the molar amount of the amine compound divided by the number of the primary and secondary amino groups of the amine compound.

Thus, for example, one equivalent of diphenylphosphorochloridate is 1 mole equivalent thereof, and one equivalent of phenylphosphorodichloridate is 0.5 mole equivalent thereof. Since aniline has one primary amino group and piperidine has one secondary amino group, one equivalent of the aniline is one mole thereof. Since phenylenediamine and piperazine each have two primary amino groups and secondary amino groups in the molecule, one equivalent thereof is 0.5 mole of all thereof.

In the process of the present invention, the reaction solvent is not necessarily used in the reaction of the phosphorohalidates and the amine compound, but the reaction solvent is preferably used so that the reaction proceeds smoothly and post- A reaction solvent having a boiling point of 130 ° C or higher is used. When the reaction solvent is used, the lower limit of the reaction solvent is not particularly limited, but is generally 0.5 parts by weight or more, and preferably 1 part by weight or more, relative to 1 part by weight of the phosphohalidate used. On the other hand, the upper limit of the amount of the reaction solvent to be used is generally 5 parts by weight or less, preferably 2 parts by weight or less, based on 1 part by weight of the phosphorohalidate used, from the viewpoint of volume efficiency.

According to the present invention, the above-mentioned proportion of phosphorohalidates and amine compounds are usually reacted at room temperature or, if necessary, at a temperature somewhat up to about 50 ° C, preferably with a reaction solvent, The reaction is initiated and then reacted at a temperature of at least 130 캜, preferably at the reflux temperature of the reaction solvent used.

In the present invention, the reaction is carried out at a temperature of 130 ° C or higher, that is, a step of reacting at a temperature of 130 ° C or higher in the reaction of the phosphorohalidate and the amine compound in the above- .

Although not limiting to the method of the present invention, a preferred embodiment of the process of the present invention is a process wherein the amine compound and the reaction solvent are introduced into the reaction vessel at room temperature or, if necessary, The amine compound is dissolved in the reaction solvent, and then the phosphorous halide is gradually added to the amine compound solution while stirring the obtained amine compound solution. Thus, during the addition of the phosphorous halide to the amine compound solution slowly, phosphoric acid ester amides of the desired phosphoric acid and hydrogen halide of the amine compound are precipitated from the amine compound solution, and the reaction mixture is composed of phosphoric acid ester amides and amine To form a dispersion comprising the hydrohalide salt of the compound.

Subsequently, when the phosphorohalidate is added all at once, the temperature of the reaction mixture is gradually raised to the initial reaction temperature, that is, to 130 ° C or higher, preferably to the reflux temperature of the used reaction solvent, and the temperature is maintained for 30 minutes The reaction is continued for several hours to several hours. Thus, while the reaction mixture is heated to the initial reaction temperature, depending on the type of amine compound and phosphorohalidate used, the reaction mixture is usually heated to about 100 ° C to 120 ° C The phosphoric acid ester amides are dissolved in the reaction solvent to form a dispersion in which only the hydrogen halide salt of the amine compound is precipitated.

Thereafter, when the reaction mixture is heated to the initial reaction temperature, that is, to a temperature of 130 ° C or higher, preferably to the reflux temperature of the used reaction solvent, the halogenation of the amine compound which is not dissolved in the reaction solvent The solids of the hydrogencarbonate gradually decrease with the progress of the reaction from about the time when the temperature of the reaction mixture reaches about 130 DEG C, and at the end of the reaction at the desired reaction temperature, the hydrohalide salt of the amine compound is completely eliminated, The reaction mixture becomes a uniform and transparent solution. Thus, when the reaction mixture becomes a uniform and transparent solution, the reaction is terminated.

Therefore, in the present invention, as described above, the phosphoric acid ester amide is dissolved in the reaction solvent to obtain a dispersion liquid in which only the hydrogen halide salt of the amine compound precipitates, and then the desired reaction temperature, that is, , It is preferable to continue the reaction until all of the hydrogen halide salt of the amine compound disappears at the reflux temperature of the reaction solvent used and the reaction mixture forms a uniform and transparent solution, that is, the reaction is terminated . Thus, at a temperature of 130 占 폚 or higher, preferably at the reflux temperature of the reaction solvent used, all of the hydrogen halide salt of the amine compound is completely eliminated until the reaction mixture forms a uniform and transparent solution, Is usually in the range of 30 minutes to several hours, although it depends on the kind of the amine compound and phosphorous halide used.

In the present invention, the mode of reacting the amine compound with the phosphohalidate is not limited to the above example. For example, if necessary, the amine compound is dissolved in a reaction solvent and heated to about 100 ° C to about 130 ° C On the other hand, phospholor halide may likewise be dissolved in a reaction solvent, heated to about 100 ° C to about 130 ° C, and then added with a solution of phosphorol halide to a solution of the amine compound.

As described later, according to the present invention, it is preferable that an inert gas or air flow in the reaction vessel throughout the reaction to remove the generated hydrogen halide gas outside the reaction system.

In the present invention, the upper limit of the reaction temperature is usually 250 占 폚 or lower, preferably 240 占 폚 or lower, although it depends on the reaction solvent when a reaction solvent is used. Particularly, in the present invention, when a reaction solvent is used, the reaction temperature is preferably in the range of 140 to 220 캜 for practical reasons, although it depends on the reaction solvent.

Examples of the reaction solvent having a boiling point of 130 ° C or higher include aromatic hydrocarbon solvents such as xylene, mesitylene, cumene, pseudocumene, solvent naphtha and so-called naphtha solvents, aliphatic hydrocarbon solvents such as isoparaffin solvents, Halogenated aromatic hydrocarbon solvents such as benzene, dichlorobenzene and trichlorobenzene, aromatic ether solvents such as diphenyl ether, and mixtures thereof are preferably used.

In the present invention, an organic solvent containing various aromatic hydrocarbons as a main component and referred to as a solvent naphtha or naphtha solvent and having a boiling point of 130 ° C or higher is contained in the above aromatic hydrocarbon solvent, and an isoparaffinic hydrocarbon is used as a main component , And an organic solvent having a boiling point of 130 ° C or higher is included in the aliphatic hydrocarbon solvent.

According to the method for producing phosphoric acid ester amides according to the present invention, an excess of amine compound is not used relative to 1 equivalent of phosphorohalidate, and according to a preferred embodiment, 0.8 equivalents to 1.2 equivalents, more preferably, By using 1 equivalent, the intended phosphoric acid ester amide can be obtained at a high yield relative to the amine compound. The reason is as follows.

That is, when the amine compound is used in an amount of 1 equivalent of the amine compound and 1 equivalent of the phosphorohalidate, the amine compound acts both as a reactant and as a hydrogen halide capturing agent to promote the reaction. Therefore, one equivalent of the amine compound and phosphorous halide 0.5 equivalents of an amine compound and 0.5 equivalents of phosphorohalidate in one equivalent of a date are reacted even at a relatively low temperature to produce corresponding phosphate ester amides. However, in this case, since 0.5 equivalent of the remaining amine compound captures the hydrogen halide produced by the above reaction to form the hydrohalide salt, in the state of the hydrohalide salt, 0.5 equivalents of the remaining phosphorohalidate Lt; / RTI > Thus, by further increasing the reaction temperature, the hydrogen halide gas is released from the hydrogen halide salt of the amine compound and is removed from the reaction system, and the amine compound is returned to the free amine compound again. Therefore, And reacts. The hydrogen halide generated at this time is removed from the reaction system without being trapped in the amine compound under high temperature reaction conditions or captured by the amine compound and hydrogen halide gas is likewise removed from the hydrogen halide salt under high temperature reaction conditions And is removed from the reaction system.

Therefore, in the production of phosphoric acid ester amides according to the present invention, it is necessary that the reaction system is in communication with the outside of the reaction system so that the hydrogen halide gas produced by the condensation reaction of the phosphorohalidates and the amine compound is removed from the reaction system In particular, according to the present invention, it is preferable to forcibly remove the hydrogen halide gas which has been separated from the hydrogen halide salt of the amine compound, out of the reaction system, thereby promoting the smooth progress of the reaction.

Therefore, according to the present invention, in the reaction of the phosphorohalidates and the amine compound, an inert gas such as nitrogen, helium, argon, carbon dioxide gas or the like is blown into the reaction vessel, It is preferable to carry out the reaction under an air stream or the reaction under suction and decompression.

In order to isolate the desired phosphoric acid ester amides from the resulting reaction mixture after reacting the phosphorohalidates and the amine compound in this way, for example, the obtained reaction mixture is cooled to precipitate the reaction product, And then washed with an aqueous base solution such as hydrochloric acid, an aqueous base solution such as sodium carbonate and then with warm water to remove unreacted materials and then dried to obtain desired phosphoric acid ester amides. Thereafter, if necessary, it may be washed with a lower alcohol such as methanol or ethanol or acetone, or recrystallized from a thermal alcohol.

According to the present invention, desired phosphoric acid ester amides can be thus obtained in correspondence with the phosphorodihalidates and amine compounds.
