Muri iki gihe, alkoholi zikoreshwa cyane mu gushushanya plastike ni 2-propylheptanol (2-PH) na isononyl alcohol (INA), zikoreshwa cyane mu gukora plastike zo mu gisekuru gitaha. Esters zikozwe mu nzoga nyinshi nka 2-PH na INA zitanga umutekano mwiza kandi zibungabunga ibidukikije.
2-PH ikorana na anhydride ya phthalate (DPHP) kugira ngo ikore di(2-propylheptyl) phthalate (DPHP). Ibikoresho bya PVC byashyizwemo pulasitiki na DPHP bigaragaza ubushobozi bwo gukingira amashanyarazi, kurwanya ikirere, kudahindagurika cyane, ndetse n'imiterere mike ya fiziki-kemikali, bigatuma bikoreshwa cyane mu nsinga, ibikoresho byo mu rugo, filime z'imodoka, na pulasitiki zo hasi. Byongeye kandi, 2-PH ishobora gukoreshwa mu gukora surfactants zikora neza kandi zidafite ionic. Mu 2012, BASF na Sinopec Yangzi Petrochemical bafatanyije gushyiraho uruganda rukora 2-PH 2 toni 80.000 ku mwaka, uruganda rwa mbere rw'ubucukuzi bwa 2-PH mu Bushinwa. Mu 2014, Shenhua Baotou Coal Chemical Company yatangije ishami rikora 2-PH 2 toni 60.000 ku mwaka, umushinga wa mbere w'ubucukuzi bwa 2-PH mu Bushinwa. Muri iki gihe, amasosiyete menshi afite imishinga yo gukoresha amakara muri olefin arimo gutegura ibikorwa bya 2-PH, birimo Yanchang Petroleum (toni 80.000 ku mwaka), China Coal Shaanxi Yulin (toni 60.000 ku mwaka), na Inner Mongolia Daxin (toni 72.700 ku mwaka).
INA ikoreshwa cyane cyane mu gukora diisononyl phthalate (DINP), igikoresho cy’ingenzi gikoreshwa muri rusange mu gushushanya. Inama Mpuzamahanga y’Inganda z’Ibikinisho yasanze DINP idateza akaga ku bana, kandi kwiyongera kwayo mu myaka ya vuba aha byatumye ikoreshwa rya INA ryiyongera. DINP ikoreshwa cyane mu modoka, insinga, hasi, mu bwubatsi, no mu zindi nganda. Mu Ukwakira 2015, ubufatanye bwa 50:50 hagati ya Sinopec na BASF bwatangiye ku mugaragaro umusaruro ku ruganda rwa INA rwa toni 180.000 ku mwaka i Maoming, muri Guangdong—urundi ruganda rukora INA mu Bushinwa rukora toni 180.000 ku mwaka. Ikoreshwa mu ngo rigera kuri toni 300.000, risiga icyuho mu gutanga ibikoresho. Mbere y’uyu mushinga, Ubushinwa bwishingikirizaga gusa ku bicuruzwa bitumizwa mu mahanga bya INA, aho toni 286.000 zatumijwe mu 2016.
2-PH na INA byombi bikorwa binyuze mu guhuza butenes ziva mu migezi ya C4 hamwe na syngas (H₂ na CO). Ubu buryo bukoresha catalysts nziza z’icyuma, kandi guhuza no guhitamo izi catalysts biracyari imbogamizi zikomeye mu musaruro wa 2-PH na INA mu gihugu. Mu myaka ya vuba aha, ibigo byinshi by’ubushakashatsi by’Abashinwa byateye imbere mu ikoranabuhanga mu musaruro wa INA no mu iterambere rya catalysts. Urugero, Laboratwari ya C1 Chemistry ya Kaminuza ya Tsinghua yakoresheje octenes zivanze zavuye muri butene oligomerization nk'ibiribwa n'umusemburo wa rhodium hamwe na triphenylphosphine oxide nk'umusemburo, bitanga umusaruro wa 90% wa isononanal, bitanga ishingiro rikomeye ryo kwagura inganda.
