Okwangoku, ii-alcohols ze-plasticizer ezisetyenziswa kakhulu yi-2-propylheptanol (2-PH) kunye ne-isononyl alcohol (INA), ezisetyenziswa kakhulu kwimveliso yee-plasticizers zesizukulwana esilandelayo. Ii-Esters ezenziwe kwii-alcohols eziphezulu ezifana ne-2-PH kunye ne-INA zibonelela ngokhuseleko olukhulu kunye nobuhlobo nokusingqongileyo.
I-2-PH isabela kunye ne-phthalic anhydride ukwenza i-di(2-propylheptyl) phthalate (DPHP). Iimveliso ze-PVC ezenziwe ngeplastiki nge-DPHP zibonisa ubushushu obuphezulu bombane, ukumelana nemozulu, ukuguquguquka okuphantsi, kunye neempawu eziphantsi ze-physico-chemical, nto leyo eyenza ukuba zisetyenziswe kakhulu kwiintambo, izixhobo zasekhaya, iifilimu zezixhobo zeemoto, kunye neeplastiki zomgangatho. Ukongeza, i-2-PH ingasetyenziselwa ukwenza ii-surfactants ezingezizo ze-ionic ezisebenza kakhulu. Ngo-2012, i-BASF kunye ne-Sinopec Yangzi Petrochemical ngokubambisana zagunyazisa isiko lokuvelisa i-2-PH yeetoni ezingama-80,000 ngonyaka, isityalo sokuqala saseTshayina se-2-PH. Ngo-2014, iShenhua Baotou Coal Chemical Company yaqalisa iyunithi yokuvelisa i-2-PH yeetoni ezingama-60,000 ngonyaka, iprojekthi yokuqala yaseTshayina ye-2-PH esekwe kumalahle. Okwangoku, iinkampani ezininzi ezineeprojekthi zokusebenzisa amalahle ukuya kwi-olefin ziceba izibonelelo ze-2-PH, kuquka iYanchang Petroleum (iitoni ezingama-80,000 ngonyaka), iShaanxi Yulin yaseTshayina (iitoni ezingama-60,000 ngonyaka), kunye ne-Inner Mongolia Daxin (iitoni ezingama-72,700 ngonyaka).
I-INA isetyenziswa kakhulu ukuvelisa i-diisononyl phthalate (DINP), i-plasticizer ebalulekileyo yenjongo ngokubanzi. I-International Council of Toy Industries ibone i-DINP njengengeyongozi ebantwaneni, kwaye imfuno yayo ekhulayo kwiminyaka yakutshanje ibangele ukwanda kokusetyenziswa kwe-INA. I-DINP isetyenziswa kakhulu kwiimoto, kwiintambo, phantsi, ekwakheni, nakwamanye amacandelo emizi-mveliso. Ngo-Okthobha ka-2015, intsebenziswano ye-50:50 phakathi kweSinopec kunye ne-BASF yaqala ngokusesikweni ukuvelisa kwisityalo se-INA esiziitoni ezili-180,000 ngonyaka eMaoming, eGuangdong—esona sixhobo sokuvelisa i-INA kuphela eTshayina. Ukusetyenziswa kwasekhaya kumalunga neetoni ezingama-300,000, okushiya umsantsa wokubonelela. Ngaphambi kwale projekthi, iTshayina yayixhomekeke ngokupheleleyo ekungenisweni kwe-INA, kunye neetoni ezingama-286,000 ezingeniswe ngo-2016.
Zombini i-2-PH kunye ne-INA ziveliswa ngokuphendula i-butenes ezivela kwi-C4 streams kunye ne-syngas (H₂ kunye ne-CO2). Le nkqubo isebenzisa ii-catalysts ze-noble metal complex, kwaye ukuhlanganiswa kunye nokukhetha kwezi catalysts kuhlala kuyimiqobo ephambili kwimveliso yasekhaya ye-2-PH kunye ne-INA. Kwiminyaka yakutshanje, amaziko ophando amaninzi aseTshayina enze inkqubela phambili kubuchwepheshe bemveliso ye-INA kunye nophuhliso lwe-catalyst. Umzekelo, i-C1 Chemistry Laboratory yeYunivesithi yaseTsinghua isebenzise ii-octenes ezixutyiweyo ezivela kwi-butene oligomerization njenge-feedstock kunye ne-rhodium catalyst ene-triphenylphosphine oxide njenge-ligand, ifumana isivuno se-90% se-isononanal, inika isiseko esiqinileyo sokwandiswa kwemizi-mveliso.
