چکیده
Cr (III) tris(2-ethylhexanoate) was synthesized and was used as catalyst for oligomerisation of ethylene. Several halocarbon compounds were used as promotor and the effect on selectivity production of the 1-hexene were investigated. The comparative studies showed that the promotion effect of chlorinated compounds were much better than that of corresponding fluoride or bromides and however multi-chloro compound which shows significant promotion effect to assist chromium center to achieve high 1-hexene formation selectivity. Results showed that the high selectivity of ethylene trimerization was 99.2% C6 in presence of Cr (2EH)3/2,5-DMP/AlEt3/1,1,2,2-Tetrachloroethane (TCE ).The effect of Al/Cr ratio on selectivity of the 1-hexene were investigated. The optimum ratio were 81.6 that high 1-hexane selectivity is obtained.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
