物が用いられる。それらは触媒中に主としてメタル状で
存在するが表面は部分的に塩化物あるいはフッ化物で覆
われている可能性が高い。In order to support the additive metal, compounds such as nitrates, carbonates, sulfates, halides, hydroxides, phosphates, perchlorates, organometallic compounds, and organic acid salts of the additive metal are used. They exist mainly in the form of metal in the catalyst, but the surface is likely to be partially covered with chloride or fluoride.
添加金属とベース金属とのモル比は、添加金属がビスマ
ス以外の場合0.5以上であることが必要であり、添加
金属がビスマスの場合0.05以上であることが必要で
ある。例えば、Hg/Pdモル比が0.5より低くなる

択率も低下してしまう。また、このモル比は大きくなっ
ても選択率には大きな影響を与えないが、大きすぎると
反応率が低下するので4以下に押さえることが好ましい
。さらには、オレフィンの中でも3FCLの選択率の高
い金属の場合は、ベース金属とのモル比を4以下の適当
な値にすることにより3FHの選択率を高くすることも
できる。The molar ratio of the added metal to the base metal needs to be 0.5 or more when the added metal is other than bismuth, and needs to be 0.05 or more when the added metal is bismuth. For example, if the Hg/Pd molar ratio is lower than 0.5, the selectivity of 3FH will decrease significantly, and the selectivity of the entire olefin will also decrease. Further, even if this molar ratio becomes large, it does not have a large effect on the selectivity, but if it is too large, the reaction rate will decrease, so it is preferable to keep it to 4 or less. Furthermore, in the case of a metal that has a high selectivity for 3FCL among olefins, the selectivity for 3FH can be increased by setting the molar ratio with the base metal to an appropriate value of 4 or less.
また上記添加金属の種類を選択することにより3FCL

/3FH production ratio can be changed.

0.58.5.8となる。For example, if the additive metals are mercury, lead, and copper, 3
The FCL/3FH production ratio is typically 0.11, respectively.
It becomes 0.58.5.8.
また、反応に用いる水素と113のモル比は0゜5〜4
.0が好ましい。この値が大きくなっても、水素化され
たパラフィン系化合物の生成は起こりにくく、オレフィ
ン(3FCLと3FH)の高選択率は保持される。しか
し4.0より大きいと不経済である。In addition, the molar ratio of hydrogen and 113 used in the reaction is 0°5 to 4
.. 0 is preferred. Even if this value becomes large, hydrogenated paraffinic compounds are less likely to be produced, and a high selectivity for olefins (3FCL and 3FH) is maintained. However, if it is larger than 4.0, it is uneconomical.
接触時間に相当するW/F(W:触媒重量L F:標準
状態における総流量mQ/秒)は、1.3〜11.4の
範囲内においては選択率に大きな影響を与えない。W/F (W: catalyst weight L F: total flow rate mQ/sec under standard conditions), which corresponds to the contact time, does not have a significant effect on the selectivity within the range of 1.3 to 11.4.
反応温度は、150〜400℃、好ましくは200〜3
00℃である。The reaction temperature is 150-400°C, preferably 200-300°C.
It is 00℃.
本発明によれば200〜300℃の比較的低い温度での
反応により3FCLおよび3FHを87〜100%の高
選択率で得ることができる。According to the present invention, 3FCL and 3FH can be obtained at a high selectivity of 87 to 100% by reaction at a relatively low temperature of 200 to 300°C.
