ホスフィンのスルホン酸塩として、(スルホフェニル)ジフェニルホスフィン、ジ(スルホフェニル)フェニルホスフィンまたはトリ(スルホフェニル)ホスフィンの第四級アンモニウム塩が知られており、これらのうち実際にはリン(3価)を60%含有するトリ(3−スルホフェニル)ホスフィンのテトラエチルアンモニウム塩がブタジエンのテロメリゼーション反応に用いられている(特公昭54−6270号公報参照) 。かかるトリ(3−スルホフェニル)ホスフィンのテトラエチルアンモニウム塩は、不純物としてリン(5価)を含有していることが推定される。このような不純物を含有したホスフィンから調製されたホスホニウム塩をテロメリゼーション触媒の構成成分とする場合、テロメリゼーション反応系中で不純物が蓄積したり、該反応系の反応基質の溶解度が変化するなど、反応に悪影響を及ぼす可能性がある。

As sulfonates of phosphines, quaternary ammonium salts of (sulfophenyl) diphenyl phosphine, di (sulfophenyl) phenyl phosphine or tri (sulfophenyl) phosphine are known, and among these, phosphorus (trivalent) is actually used. The tetraethylammonium salt of tri (3-sulfophenyl) phosphine containing 60% of the above is used for the telomerization reaction of butadiene (see JP-B-54-6270). Tetraethylammonium salts of such Application Benefits (3-sulfophenyl) e Sufin is estimated to contain phosphorus (pentavalent) as an impurity. When a phosphonium salt prepared from phosphine containing such an impurity is used as a component of the telomerization catalyst, the impurity is accumulated in the telomerization reaction system, or the solubility of the reaction substrate of the reaction system is changed. And may adversely affect the reaction.

本発明者らは沈澱物発生の原因究明に努めた結果、ブタジエンと水との二量化反応を長期間連続して行う際には、反応液中においてホスホニウム塩の成分として含まれるアルカリ金属イオンの濃度が予想外に上がること、かかるアルカリ金属イオンが反応促進剤である重炭酸イオンまたは炭酸イオンと反応して重炭酸アルカリ金属塩および/または炭酸アルカリ金属塩となること、これらのアルカリ金属塩が沈殿物として析出することを解明した。本来、ブタジエンと水との二量化反応の条件下では、重炭酸アルカリ金属塩および炭酸アルカリ金属塩は溶解状態を保つことから、上記の現象は極めて意外であった。

As a result of the present inventors' efforts to find out the cause of precipitate formation, when the dimerization reaction of butadiene and water is carried out continuously for a long period of time, the alkali metal ion contained as a component of phosphonium salt in the reaction solution The concentration is unexpectedly increased, the alkali metal ion is reacted with the reaction promoter bicarbonate ion or carbonate ion to form an alkali metal bicarbonate and / or alkali metal carbonate, and these alkali metal salts are It clarified that it precipitated as a precipitate. Originally, in the conditions of dimerization reaction of butadiene and water, alkali metal bicarbonate and alkali metal carbonates from keeping the dissolved state, the above phenomenon was quite surprising.
