Ethylene cracking C5 kagawo kakang'ono mumlengalenga kuthamanga rectification intercepts 45-75â isoprene wolemera chigawo monga zopangira A; ethylene cracking C5 kagawo kakang'ono mumlengalenga kuthamanga rectification intercepts 25-45â isoprene wolemera chigawo monga zopangira B; Ethylene cracking C9 fraction ndi vacuum yokonzedwa pansi pa 0.08ï½0.095MPa,Petroleum Resin ndipo kachigawo kakang'ono ka 140ï½180â kamatengedwa ngati zopangira C. Zida zitatu pamwambapa A, B ndi C zakonzedwa molingana ndi kuchuluka kwa chiŵerengero cha 1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization zopangira D;
Pambuyo pochotsa madzi m'thupi zomwe tazitchula pamwambapa zopangira ma polymerization D kudzera munsanja yonyamula ma molekyulu ya 4A, Petroleum Resin selective hydrogenation imachitidwa ndi Pd/Al2O3 chothandizira kuchotsa alkyne, Petroleum Resin kenako 0.05 mpaka 0.5 wt% ya FriedelCrafts chothandizira ndikuwonjezedwa, prepolymerized pa firiji kwa maola 0,5 mpaka 1.5, Petroleum Resin kenako calcium hydroxide Chothandizira chimachotsedwa kusakaniza ndi methanol, ndipo pambuyo pa distillation, petroleum Resin the polima yaiwisi kachigawo E yokhala ndi kuwira kwa 25 mpaka 180 ° C imapezeka. Petroleum Resin pamwamba polima zopangira E ndi prepolymerized mu mkulu-anzanu reaction ketulo ndi oyambitsa pa kutentha kwa 180 ° C mpaka 230 ° C kwa 3 mpaka 5 hours. Pezani mankhwala a dimerization F a Centaolefin ndi Styrene kapena Methyl Styrene;
Pogwiritsa ntchito mankhwala omwe tawatchulawa a dimerization F ngati zopangira, Petroleum Resin kusakanikirana ndi zosungunulira zosungunulira pamlingo wa 1:0.1 mpaka 1.0, Petroleum Resin ndikuwonjezera chothandizira cha boron trifluoride chowerengera 0.1 mpaka 0.5% ya unyinji wonsewo. wa zinthu kuti catalyze polymerization pa 30 kuti 65 ° C 2 kuti mdima wachikasu kuti bulauni polymerization njira anapezedwa 5 hours. The polymerization njira anavula chothandizira ndi osakaniza kashiamu hydroxide ndi methanol kupeza wotumbululuka chikasu utomoni njira; Petroleum utomoni pamwamba utomoni njira anali pansi magetsi desalination ndi kutaya madzi m`thupi pa 50 kuti 80 ° C. Pass yogwira Al2O3 bedi olimba. pa â;
The C5/C9 mafuta utomoni yankho pambuyo pretreatment pamwamba kusungunuka mu dilution zosungunulira pa misa chiŵerengero cha 1: 1 mpaka 5, ndipo pansi pa hydrogenation anachita pamaso pa kusinthidwa Pd chothandizira kupeza hydrogenated diluted utomoni yankho. . ï½295â, reaction hydrogen pressure is 10.0ï½17.0MPa,Petroleum Resin reaction space velocity is 0.125ï½0.333h/1, reaction time is 3½8h;Petroleum Resin chotsani zosungunulira ndi zotsika Polima,Petroleum Resin , C5/C9 hydrogenated petroleum resin.
