HFO-1132の製造方法。
本開示のHFC-143の製造方法は、1,1,2-トリフルオロエチレンを、還元剤と還元反応させてHFC-143を得る。
本開示は、上述のHFC-143の製造方法により得られるHFC-143を脱フッ化水素化することによりHFO-1132を得る工程を含むHFO-1132の製造方法に関する発明を含む。当該発明においては、例えば、下記反応式1に示すとおり、1,1,2-トリフルオロエチレンと還元剤とを反応させて、HFC-143を得る工程(a)、及び該工程(a)で得られるHFC-143を脱フッ化水素することによりHFO-1132を得る工程(b)を含む、HFO-1132の製造方法とすることができる。
工程(a)は、1,1,2-トリフルオロエチレンと還元剤とを触媒の存在下で反応させてHFC-143を得る。工程(a)については、既述のHFC-143の製造方法に基づき、実施することができる。
工程(b)では、工程(a)で得られたHFC-143を脱フッ化水素化することによりHFO-1132を得る。
工程(b)で得られるHFO-1132はHFO-1132(E)及びHFO-1132(Z)を含む。HFO-1132(E)及びHFO-1132(Z)を含む混合物からHFO-1132(E)のみを得るため、或いはHFO-1132(E)の含有率を高めるための異性化工程としての工程(c)を、工程(b)の次に設けることも好ましい。
1,1,2-トリフルオロエチレンからHFC-143の製造/工程(a)
Pdを1.5質量%担持した活性炭触媒を、1kg、内径50mmのSUS304製反応管に充填し、200℃、3時間窒素パージにより乾燥した。その後、1,1,2-トリフルオロエチレンを300Nml/min、及び水素を1000Nml/min(Nml/min とは、0℃、大気圧0.1013MPaでのガス流量を示す。)で供給し、反応温度200℃、接触時間(W/F0)=20、反応圧力0.1MPaGにて還元反応を行った。出口ガスを水洗後、塩化カルシウムで乾燥したのちGS-GASPROキャピラリーカラム(0.32mm×60m)を装備したGC(島津製 GC-2030)により分析した。反応温度ごとの1,1,2-トリフルオロエチレン転化率とHFC-143選択率を以下の表1に示す。
HFC-143からHFO-1132の製造/工程(b)
フッ素化触媒として、組成式:CrO2で表される酸化クロムにフッ素化処理を施して得られた触媒10g(フッ素含有量約15.0質量%)を、内径15mm、長さ1mの管状ハステロイ製反応器に充填した。この反応管を大気圧(0.1013MPa)下で400℃に維持し、HFC-143を15.0Nml/minの流速で供給した。接触時間W/Foは40.0 g・sec/Nmlであった。反応開始4時間後、HFC-143の転化率は98%、HFO-1132の選択率は89%であった。HFO-1132の2種類の異性体、1,2-ジフルオロエチレン(E)と1,2-ジフルオロエチレン(Z)のモル比率は19/81であった。
異性化反応/工程(c)
実施例2で使用したものと同様のCrO2で表される酸化クロムにフッ素化処理を施して得られた触媒を外径12.7mm、長さ700mmの反応器に10g充填し、異性化反応を行った。1,2-ジフルオロエチレン(Z)に、触媒の劣化防止のために窒素、酸素を添加した原料ガスを6~10Nml/minの速度で反応器に供給し、反応温度250~300℃、で異性化反応を行った。反応の結果を表1に示す。
