本発明では、原料としては、1,1,1,2,3−ペンタフルオロプロパン(HFC−245eb)を用いる。1,1,1,2,3−ペンタフルオロプロパンは、種々の方法で合成可能であり、例えば、日本特許3158440号公報に記載されている方法に従って、1,1,2,3,3,3−ヘキサフルオロプロペンを原料として合成することができる。以下、この方法について簡単に説明する。
本発明方法では、1,1,1,2,3−ペンタフルオロプロパン(HFC−245eb)を原料として用い、脱フッ化水素反応によって、2,3,3,3-テトラフルオロプロペン(HFO-1234yf)を製造する。

(1)高フッ素化酸化クロム触媒の調製
硝酸クロムの5.7% 水溶液765gに、10%のアンモニア水114g を加えて沈殿を得た。得られた沈殿を濾過洗浄後、空気中で120 ℃ で12 時間乾燥して、水酸化クロムを得た。これを直径3.0mm、高さ3.0mmのペレットに成形し、窒素気流中400℃ で2時間焼成した。得られた酸化クロムは、Cr量の定量及び元素分析の結果、CrO2.0と特定された。このペレット状の酸化クロムをハステロイC製反応管に充填し、フッ化水素を窒素にて20 vol%に希釈して反応管に供給し、200〜360℃まで段階的に温度を上げながら加熱し、次いで、100%HFにより220時間フッ素化した。得られたフッ素化された酸化クロムの比表面積(BET法による)は70m2/gであり、そのフッ素含量は31.4重量%であった。
図1に模式的に示す工程に従って、下記の方法で2,3,3,3-テトラフルオロプロペン(HFC-1234yf)を合成した。
1,1,1,2,3-ペンタフルオロプロパン (HFC-245eb) を4L / min (0℃、0.1MPaでの流量、 W/Fo=30g・sec/cc)で供給したこと以外は、実施例1と同様の方法でHFC-245ebの脱フッ化水素反応と副生成物の循環操作を行った。このときのHFC-245ebの転化率は実質100%であった。各ストリームにおける各成分の流量(kg/hr)を下記表2に示す。
反応温度を450℃としたこと以外は、実施例1と同様の方法でHFC-245ebの脱フッ化水素反応と副生成物の循環操作を行った。このときのHFC-245ebの転化率は実質100%であった。各ストリームにおける各成分の流量(kg/hr)を下記表3に示す。
