本発明は、ジアリルエチルメチルアンモニウムエチルサルフェイトと二酸化イオウとの共重合体の製造方法に関する。
さらに詳しくは本発明は、ファインケミカル分野に使用可能で、かつ水に可溶で、有機溶媒への溶解性の高い、ジアリルエチルメチルアンモニウムエチルサルフェイトと二酸化イオウとの共重合体の製造方法に関する。
The present invention relates to a method for producing a copolymer of diallylethylmethylammonium ethyl sulfate and sulfur dioxide.
More particularly, the present invention relates to a method for producing a copolymer of diallylethylmethylammonium ethyl sulfate and sulfur dioxide that can be used in the fine chemical field, is soluble in water, and has high solubility in an organic solvent.
ジアリルジアルキルアンモニウムクロリドと二酸化イオウとの共重合体は、ジアリルジアルキルアンモニウムクロリドと二酸化イオウとを共重合させることにより簡単に製造できる点から工業的に製造され、水溶性塗料や染色物の染色堅牢度向上剤等のファインケミカル分野で使用することが提案されている(例えば、特許文献1参照)。 Copolymers of diallyldialkylammonium chloride and sulfur dioxide are industrially produced because they can be easily produced by copolymerizing diallyldialkylammonium chloride and sulfur dioxide, and dyeing fastness of water-soluble paints and dyeings It has been proposed to be used in the field of fine chemicals such as improvers (see, for example, Patent Document 1).
しかしながら、地球環境の保全の高まりとともにファインケミカル分野で使用される各種薬剤も、塩素を含まないものが求められてきており、ジアリルジアルキルアンモニウムクロリドと二酸化イオウとの共重合体の代りに、ジアリルジアルキルアンモニウムのクロリド以外の塩と二酸化イオウとの共重合体が求められるようになってきている。 However, various chemicals used in the field of fine chemicals have been demanded along with the enhancement of global environment conservation, and chlorine-free drugs have been demanded. Instead of a copolymer of diallyldialkylammonium chloride and sulfur dioxide, diallyldialkylammonium Copolymers of salts other than chlorides with sulfur dioxide have been demanded.
ところが、特許文献1に記載のように、ジアリルジアルキルアンモニウムのクロリド以外の塩と二酸化イオウとの共重合体を、対応するジアリルジアルキルアンモニウムの塩と二酸化イオウとの反応により実用的に製造することは困難である。 However, as described in Patent Document 1, it is practical to produce a copolymer of a salt other than the diallyldialkylammonium chloride and sulfur dioxide by reacting the corresponding diallyldialkylammonium salt with sulfur dioxide. Have difficulty.
例えば、ジアリルジアルキルアンモニウムのヨウ化物塩と二酸化イオウとを共重合して得られる共重合体は、重合中にヨウ素が一部遊離するために着色することがある。また、ジアリルジアルキルアンモニウムの有機酸塩と二酸化イオウとを共重合しても、得られる有機酸塩の共重合体の収率は低い。さらに、ジアリルジアルキルアンモニウムの硫酸塩または亜硫酸塩と二酸化イオウとを共重合しようとしても、得られる共重合体の硫酸塩または亜硫酸塩を、製造単離することが困難である。 For example, a copolymer obtained by copolymerizing an iodide salt of diallyldialkylammonium and sulfur dioxide may be colored due to partial liberation of iodine during the polymerization. Moreover, even if the organic acid salt of diallyldialkylammonium and sulfur dioxide are copolymerized, the yield of the resulting organic acid acid salt copolymer is low. Further, even if diallyldialkylammonium sulfate or sulfite is to be copolymerized with sulfur dioxide, it is difficult to produce and isolate the resulting copolymer sulfate or sulfite.
本発明は、このような事情のもとで、ジアリルジアルキルアンモニウムのクロリド以外の塩と二酸化イオウとの共重合体を簡単な操作により高収率で製造する方法を提供することを目的とする。 The present invention is, under such circumstances, the purpose is to provide a process for preparing in high yield by easy single operation co polymer with a salt and sulfur dioxide other than chloride diallyldialkylammonium To do.
本発明者らは、上記の問題を解決するため、ジアリルジアルキルアンモニウムのクロリド以外の塩と二酸化イオウとの共重合体の製造を種々検討したところ、意外にも原料として、ジアリルジアルキルアンモニウムクロリドの代わりに有機酸塩の一種であるジアリルエチルメチルアンモニウムエチルサルフェイトを用いて、これを二酸化イオウと共重合させると、ジアリルエチルメチルアンモニウムエチルサルフェイトと二酸化イオウとの新規な共重合体が収率良く得られることを見出した。また、本発明者らはこの新規共重合体は、水溶性であり、かつ、対応するジアリルジアルキルアンモニウムクロリドと二酸化イオウとの共重合体に比べると、有機溶媒への溶解性に優れ、ファインケミカル分野の用途に極めて有効なことを見出した。 In order to solve the above problems, the present inventors have conducted various studies on the production of a copolymer of a salt other than diallyldialkylammonium chloride and sulfur dioxide. Surprisingly, instead of diallyldialkylammonium chloride, When diallylethylmethylammonium ethylsulfate, a kind of organic acid salt, is copolymerized with sulfur dioxide, a new copolymer of diallylethylmethylammonium ethylsulfate and sulfur dioxide is obtained in high yield. It was found that it can be obtained. Further, the present inventors have found that this novel copolymer is water-soluble and has excellent solubility in organic solvents as compared with the corresponding copolymer of diallyldialkylammonium chloride and sulfur dioxide. It was found to be extremely effective for the use of.
