Description
実施例1(固定床):
ガラス反応器(直径16mm、全高400mm)内に、3,4−エチレンジオキシチオフェン−2,5−ジカルボン酸の乾燥原料4gを装入し、窒素流中で300℃の最高反応温度に加熱した(加熱速度2℃/分)。80分の時間に亘り、出発物質の反応を完了させた。装入した4g(1.7×10−2モル)のうち、3.5g(1.52×10−2モル)の反応を完了させ、少量を窒素流により反応器から排出した。後接続された冷却トラップ中で3,4−エチレンジオキシチオフェン−2,5−ジカルボン酸と3,4−エチレンジオキシチオフェンとから成る生成物混合物2.89gを捕捉した。HPLCにより測定された3,4−エチレンジオキシチオフェンの含分は>90質量%であった。
ガラス反応器(直径50mm、全高730mm、10mmのガス分配器フリットを有する円錐形ガス取水口)内に、3,4−エチレンジオキシチオフェン−2,5−ジカルボン酸の乾燥原料120.0g(0.52モル)を装入し、窒素流中で(標準状態)320℃の最高反応温度に加熱した(加熱速度2℃/分)。100分の時間に亘り、出発物質の反応を完了させた。原料の量のうち、32.0g(0.139モル)の反応を完了させた。後接続された冷却トラップ中で生成物混合物16.6gを凝縮させた。3,4−エチレンジオキシチオフェンの含分は>94質量%であった。
付加的なガス分配器を有するガラス反応器(直径95mm、全高700mm、ガス分配器フリット95mm)内に、直径160〜250mmのケイ砂3000gを装入し、石英床中で窒素を用いた流動化下に280℃の反応温度に加熱した。3,4−エチレンジオキシチオフェン−2,5−ジカルボン酸0.1351モルと塩基性炭酸銅との質量比1:1から成る混合物を58分の時間に亘って窒素で流動化された反応器中に添加した。そこで脱カルボキシル化を行い、生成物を複数の直列接続された冷却トラップ中で凝縮させた。収率はY=83モル%であり、HPLCにより測定された生成物の純度は94質量%を上回っていた。反応器から排出させ、サイクロン中で分離された固体を再度出発物質として使用する。
