Ukuqhekeka kwe-ethylene C5 ingxenye yokulungiswa kwengcindezi yasemkhathini ihlangana nengxenye engu-45-75â isoprene ethuthukisiwe njengempahla eluhlaza A; i-ethylene cracking C5 ingxenyenamba yokulungiswa kwengcindezi yasemkhathini ihlanganisa 25-45â isakhi esinothisiwe ye-isoprene njengempahla eluhlaza B; Ingxenye ye-Ethylene eqhekeka i-C9 ivacuum elungiswa ngaphansi kuka-0.08ï½0.095MPa,Petroleum Resin futhi ingxenyenamba enephuzu elibilayo elingu-140ï½180â ithathwa njengento eluhlaza C. Izinto zokusetshenziswa ezingenhla ezintathu A, B kanye no-C zilungiswa ngokuvumelana isilinganiso sesisindo esingu-1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization impahla eluhlaza D;
Ngemuva kokuqeda amanzi e-polymerization eshiwo ngenhla embhoshongweni wokupakisha we-4A we-molecular sieve, i-Petroleum Resin selective hydrogenation yenziwa nge-Pd/Al2O3 catalyst yokususa i-alkyne, i-Petroleum Resin bese ingezwa u-0.05 kuya ku-0.5 wt% we-FriedelCrafts catalyst. I-prepolymerized ekamelweni lokushisa amahora angu-0.5 kuya kwangu-1.5, i-Petroleum Resin bese i-calcium hydroxide I-catalyst ikhishwa engxubeni ne-methanol, futhi ngemva kokukhishwa kwe-distillation, i-petroleum Resin ingxenyana ye-polymer eluhlaza E enephuzu lokubilisa elingu-25 kuya ku-180 ° C iyatholakala. ;I-Petroleum Resin le nto eluhlaza eyenziwe nge-polymerized E engenhla yenziwa i-polymerized kugedlela lokusabela lokucindezela okuphezulu elinyakazayo ezingeni lokushisa elingu-180°C kuya ku-230°C amahora amathathu kuya kwangu-5. Thola umkhiqizo we-dimerization F we-Centaolefin ne-Styrene noma i-Methyl Styrene;
Kusetshenziswa umkhiqizo oshiwo ngenhla we-dimerization F njengento eluhlaza, i-Petroleum Resin ixutshwa ne-solvent ehlanjululwe ngesilinganiso sesisindo esingu-1:0.1 kuye ku-1.0, i-Petroleum Resin kanye nokwengeza i-gaseous boron trifluoride catalyst accounting engu-0.1 kuya ku-0.5% yenani eliphelele lesisindo. kwento yokwenza i-polymerization ku-30 kuya ku-65°C 2 kuya Isixazululo se-polymerization esiphuzi okumnyama ukuya ensundu sitholwe emahoreni angu-5. Isixazululo se-polymerization sasuswa i-catalyst ngengxube ye-calcium hydroxide ne-methanol ukuze kutholwe isixazululo se-resin ephuzi; ngo-â;
Isixazululo se-petroleum resin ye-C5/C9 ngemva kokwelashwa kwangaphambili okungenhla sincibilika ku-solvent ye-dilution ngesilinganiso sesisindo esingu-1:1 kuya ku-5, futhi singaphansi kokusabela kwe-hydrogenation phambi kwe-catalyst ye-Pd eguquliwe ukuze kutholwe isixazululo se-hydrogenated diluted resin. . ï½295â, reaction hydrogen pressure is 10.0ï½17.0MPa,Petroleum Resin reaction space velocity is 0.125ï½0.333h/1, isikhathi sokuphendula ngu-3½8h;Petroleum Resin khipha inxabiliki nePolymer ephansi,Petroleum Resin , C5/C9 i-hydrogenated petroleum resin.
