초록

Montmorillonite가 주성분인 산성백토로부터 여러 양이온을 교환시켜 촉매를 제조하여 ethylene의 중합활성에 대하여 연구하였다. $Ni^{2+}$-Mont촉매상에서는 ethylene이 선택적으로 n-butene으로 이량화 되었으며, 그 활성은 150$^{\circ}$C 의 진공온도에서 최고로 나타났다. 그리고 촉매활성의 변화는 촉매의 산도와 밀접한 관계가 있었다. $Ni^{2+}$-Mont 촉매는 ethylene의 중합에 높은 활성을 나타내었으며, 그 활성은 450$^{\circ}C$의 진공온도에서 최고로 나타났다. 그리고 $Cr^{3+}$-Mont의 활성점은 $Cr^{3+}$이온으로 생각되었다.

Several cation exchanged-layer silicate catalysts were prepared from acid clay mainly consisted of montmorillonite, and their catalytic activities for the ethylene polymerization were studied at room temperature. It was found that over$Ni^{2+}$ -Mont, dimerization of ethylene to n-butene proceeded selectively.$Ni^{2+}$ -Mont was activated by evacuation at elevated temperature, giving a maximum temperature, 150$^{\circ}$C . The variations in catalytic activities were closely correlated to the acidity of the catalysts.$Cr^{3+}$ -Mont exhibited a high activity for the polymerization, showing, a maximum at the evacuation temperature of 450$^{\circ}C$. The active site in $Cr^{3+}$-Mont was considered to be $Cr^{3+}$ ion.
