[Detailed Description of the Invention] The present invention relates to a novel method for producing dimethyldiallylammonium halide monomer (hereinafter abbreviated as DMDAAH).
When producing DMDAAH, a tertiary reaction is caused with excess dimethylamine and allyl halide, and the resulting dimethyl monoallylamine is quaternized with allyl halide.
This is a method for producing DMDAAH. DMDAAH is produced by reacting dimethylamine with twice the molar amount of allyl halide in an aqueous inorganic alkali solution such as caustic soda, filtering the salt produced during the reaction, and distilling off the by-products by topping under reduced pressure. It is known. However, DMDAAH produced by this method contains impurities in its aqueous solution. For example, the formation of monomethyltriallylammonium halide due to the monomethylamine contained in a significant amount in the raw material dimethylamine, the hydrochloride of dimethylmonoallylamine, and even the alkali metal halides generated during the reaction remain as impurities. do. For this reason, when producing a polymer from DMDAAH, the polymerization rate is slow, the polymerization rate and degree of polymerization do not increase, and in some cases, an insoluble gel is formed during polymerization, making the polymerization solution opaque. Therefore, as a method for removing these impurities, monomethylamine in the raw material is removed using precision distillation or an adsorbent such as zeolite.
Alternatively, methods have been disclosed in which vacuum topping and pH-adjusted steam distillation are performed after the reaction. However, even if these steps are added, it is not possible to remove the alkali metal halides dissolved in the aqueous solution, and impurities such as dimethylamine halogenates also remain. In view of this situation, the present inventors have conducted extensive research and found that without using an inorganic alkali during the reaction,
Therefore, we have discovered a method for producing highly pure DMDAAH that does not contain any alkali metal halides in the product. That is, in the present invention, when producing DMDAAH from dimethylamine and allyl halide, as the first stage reaction, using excess dimethylamine (1.5 times mole or more and 4.0 times mole or less relative to allyl halide) and allyl halide,
This is a method for producing DMDAAH, which is characterized by causing a tertiaryization reaction, separating a separated product, and then quaternizing the produced dimethylmonoallylamine with allyl halide. The meaning of reacting excess dimethylamine with allyl halide in the first stage tertiaryization reaction is explained as follows. In other words, in the conventional method
By making an inorganic alkali present during the production of DMDAAH, the first step product of dimethylamine and allyl halide, dimethylmonoallylamine halide, is dehalogenated to obtain dimethylmonoallylamine, and the following quaternary The process was moving on to conversion. In the present invention, instead of inorganic alkali,
Stronger basicity than dimethyl monoallylamine,
Excess dimethylamine (relative to allyl halide)
1.5 times mole or more and 4.0 times mole or less) to dehalogenate dimethylmonoallylamine halide salt. The amount of dimethylamine in the first stage tertiary reaction is suitably in the range of 1.5 times mole or more and 4.0 times mole or less, more preferably 1.8 times mole or more and 2.5 times mole or less, based on allyl halide. If the molar ratio is less than 1.5, the efficiency of dehalogenating acid will be poor, resulting in poor yield of dimethylmonoallylamine and low purity. On the other hand, at a molar ratio greater than 4.0, a considerable amount of dimethylamine remains as an unreacted product, resulting in poor purity of dimethylmonoallylamine. After the first stage tertiary reaction is completed, the system is separated into an organic layer of dimethylmonoallylamine and an aqueous solution layer containing a dimethylamine halide salt. The dimethylmonoallylamine in the upper layer is further quaternized with allyl chloride, while the separated lower layer is dehalogenated using an inorganic alkali such as caustic soda to recover dimethylamine. Furthermore, the recovered dimethylamine is used for the production of the next lot, thus making it possible to recycle the raw material dimethylamine. DMDAAH obtained by the above method is a pale yellow transparent aqueous solution, but if necessary, operations such as treatment with activated carbon or removal of trace impurities by vacuum topping can be added to improve the hue. It is. The DMDAAH obtained according to the present invention does not contain any inorganic alkali halogen salt in its aqueous solution and can be made to have little impurity. Therefore, by polymerizing the DMDAAH thus obtained in the presence of a radical polymerization initiator, it can be made into a polymer with a high polymerization rate and degree of polymerization. DMDAAH polymer is a special cationic polymer that can be used in a wide range of fields including civil engineering, pulp and paper, and water treatment. The present invention will be explained below based on Examples. Note that all percentages are based on weight. Example 1 4 equipped with stirrer, cooler and thermometer
Put 522 g (5.80 mol) of a 50% dimethylamine aqueous solution with a monomethylamine content of 3.68% in dimethylamine into a two-necked flask, and add allyl chloride.
222 g (2.90 mol) was added dropwise over 3 hours. The reaction was continued for another 2 hours, and the reaction solution was allowed to stand overnight, after which the dimethylmonoallylamine layer was separated. The yield of the obtained dimethyl monoalulamine layer was 77.3% based on allyl chloride. Further, the purity of dimethylmonoallylamine was analyzed by FID type gas chromatography, and it was found that dimethylmonoallylamine containing 0.55% dimethylamine and 3.3% water with a purity of 96.1% was obtained. 132 g of water was added to this dimethylmonoallylamine layer, and 165 g of allyl chloride was added dropwise over 2 hours.The reaction was then continued under reflux, and the reaction solution became transparent in about 2 hours. The reaction was continued for an additional hour. Activated carbon was added to the dimethyldiallylammonium chloride aqueous solution obtained in this way, and after topping under reduced pressure, the activated carbon was filtered to obtain a colorless and transparent aqueous dimethyldiallylammonium chloride solution. Table 1 shows the analysis results of the obtained dimethyldiallylammonium chloride aqueous solution. Examples 2 to 5 A first-stage tertiary reaction was carried out in the same manner as in Example 1 by changing the reaction molar ratio of dimethylamine and allyl chloride. In the quaternization reaction, distilled water is added to the obtained dimethylmonoallylamine (dimethylmonoallylamine excluding water and dimethylamine) so that the solid content of the final dimethyldiallylammonium chloride is 70%. Further, a quaternization reaction was carried out using allyl chloride in the same number of moles as dimethylmonoallylamine. Further, post-treatment was carried out under the same conditions as in Example 1. Table 1 shows the analysis results of the obtained dimethyldiallylammonium chloride aqueous solution. Comparative Example 1 Using the same equipment as in Example 1, dimethylamine
222 g of allyl chloride having the same number of moles was added dropwise to 261 g (2.90 mol) of a 50% aqueous solution over 3 hours.
48% caustic soda aqueous solution 1 hour after the start of dropping
246 g (2.95 mol) was added dropwise over 2 hours in the same manner as allyl chloride. Stirring was continued for 2 hours. Further, 237 g (3.10 mol) of allyl chloride was added dropwise over 2 hours, and then the reaction temperature was kept at ambient temperature and the reaction was carried out for 5 hours. The resulting dimethyldiallylammonium chloride aqueous solution was filtered to remove the generated common salt, and then 9.3 g of activated carbon was added and post-treated in the same manner as in Example 1. Table 1 shows the analysis results of the dimethyldiallylammonium chloride aqueous solution obtained in this way. Comparative Example 2 Using the same equipment as in Example 1, dimethylamine
222 g of allyl chloride having the same number of moles was added dropwise to 261 g (2.90 mol) of a 50% aqueous solution over 3 hours, and stirring was continued for an additional 2 hours. Next, 242 g (2.90 mol) of a 48% caustic soda aqueous solution was added dropwise over 2 hours, kept for another 2 hours, and then left overnight. After adding 110 g of water to 168 g of the upper layer separated into two layers and dropping 126 g (1.65 mol) of allyl chloride, the reaction temperature was maintained at 45° C. for 3 hours to carry out quaternization. The obtained dimethyldiallylammonium chloride aqueous solution was post-treated in the same manner as in Example 1. In Table 1, the closer the water-soluble free chlorine content (%) is to the theoretical value of 22.0, the higher the purity, and the closer to the theoretical value of 198.0, the higher the purity of Br. It was found that a pure product could be obtained. It is also clear that the present invention is an advantageous method that does not contain any halogen salts of inorganic alkalis. 【table】
