Description
ジョンソンマッセイにより市販される30gの0.8%のパラジウム炭素触媒(3mm押出炭素担体粒子上Pd)を直径2cmのガラス管にロードし、約40cmのベッド長さを得た。管を水平管炉内に含有させた。次いで、31ml/分の窒素フローをベッドを通じて開始した。次いで、ベッドの温度を300℃に上昇させ、1,2-ジクロロエタン(二塩化エチレン、EDC)を窒素流に導入した。これは、窒素流を120℃に加熱された金属コイルを通過させることにより達成し、GLCポンプを介してEDC液体を0.25ml/分のフローでコイルに注入した。反応中、異なる時間にガスクロマトグラフィーで反応器排水を分析し、そして、結果(排水流中質量%)を表1に示す。EDCは脱塩化水素し、生成物流中およそ50%のVCM及び約0.6%のアセチレンを得たように思われる。約400分後、EDCフローを停止し、触媒ベッドを窒素化で冷却した。
