Description
精製される相をDBD処理する、すなわち他の添加剤を使用しない。
ハロゲン化水素(HX)および/またはハロゲン(X2)(有利にXはClである)および/または希ガス(He、Ar、Xe)または窒素のような1種以上の添加剤の存在でDBD処理する。
最初に添加剤を使用せずにDBD処理し、引き続き少なくとも1種の前記添加剤の存在で処理を継続する。
1つの例において、2つの同軸溶融シリカ管により反応空間を形成し、こうして形成される環状間隙の平均直径は有利に25〜30mmであり、長さは250〜300mmである。直径を増加するおよび/または管状反応器を並列に接続する(管束)ことにより、規模の拡大を達成できる。しかし平面配置も同様に可能である。この点で前記方法は反応器面積により記載されるように拡大/縮小できることを記載できる。
