Ethylene kapiti C5 hautanga hautanga pehanga whakatikatika haukoti 45-75â isoprene wae whakarangatira hei rauemi mata A; kapiti ethylene C5 hautanga hautau pehanga whakatikatika haukoti 25-45â isoprene wahanga whakarangatira hei rauemi mata B; Ko te hautanga ethylene cracking C9 ka whakatikahia i raro i te 0.08ï½0.095MPa, Petroleum Resin me te hautanga me te ira koropu o te 140ï½180â ka tangohia hei rauemi mata C. Ko nga rauemi mata e toru o runga ake nei A, B me C kua rite ki te te ōwehenga papatipu o te 1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization raw rauemi D;
I muri i te whakamaroketanga o te polymerization i runga ake nei i te rauemi D na roto i te 4A molecular sieve kikii pourewa, Petroleum Resin selective hydrogenation ka mahia ki te Pd/Al2O3 catalyst ki te tango alkyne, Petroleum Resin me te 0.05 ki te 0.5 wt% o te FriedelCrafts whakakōkī ka tāpirihia, katahi. ka whakapolymerized i te pāmahana rūma mo te 0.5 ki te 1.5 haora, Petroleum Resin me te konupūmā waihā ka tangohia te whakakōkī mai i te ranunga me te methanol, ā, i muri i te whakamahana, Petroleum Resin te hautanga o te rauemi matawai waerau E whai ira koropupū o te 25 ki te 180°C ka whiwhi. ;Petroleum Resin Ko te rauemi mata polymerized i runga ake ka whakapolymerized i roto i te ketere tauhohenga teitei me te whakaoho i te mahana o te 180°C ki te 230°C mo te 3 ki te 5 haora. Tikina te hua dimerization F o Centaolefin me Styrene me Methyl Styrene ranei;
Ma te whakamahi i te hua dimerization F kua whakahuahia ake nei hei rauemi mata, ka konatunatua te Petroleum Resin ki te whakarewa waimeha i te tauwehenga papatipu o te 1:0.1 ki te 1.0, Petroleum Resin me te taapiri i te whakakorikori boron trifluoride mo te 0.1 ki te 0.5% o te katoa o te papatipu. o te rauemi hei whakakoi i te polymerization i te 30 ki te 65°C 2 ki He otinga polymerization he kowhai pouri ki te parauri i whiwhi i roto i te 5 haora. Ko te otinga polymerization i tihorea mai i te whakakorikori me te ranunga o te konupūmā waihā me te methanol ki te whiwhi i te otinga kapia kowhai koma; i â;
Ko te wairewa kapia hinu C5/C9 i muri i te maimoatanga i runga ake nei ka rewa i roto i te waimeha waimeha i te tauwehenga papatipu o te 1:1 ki te 5, ka tukuna ki te tauhohenga hauwai i te aroaro o te whakakorikori Pd kua whakarereketia kia whiwhi ai i te wairewa kapia waimeha. . ï½295â, ko te pehanga hauwai tauhohenga he 10.0ï½17.0MPa, Ko te tere mokowā tauhohenga Petroleum Resin he 0.125ï½0.333h/1, ko te wa tauhohenga he 3ï½8h; Petroleum Resin tango i te whakarewa me te Polymer iti, Petroleum Resin e he , C5/C9 kapia hinu hinu.
