Hona jwale, dino tse tahang tse sebediswang haholo tsa plasticizer ke 2-propylheptanol (2-PH) le isononyl alcohol (INA), tse sebediswang haholo tlhahisong ya di-plasticizer tsa moloko o latelang. Di-Ester tse entsweng ka dino tse tahang tse phahameng tse kang 2-PH le INA di fana ka polokeho e kgolo le botsoalle tikolohong.
2-PH e arabela le phthalic anhydride ho etsa di(2-propylheptyl) phthalate (DPHP). Dihlahiswa tsa PVC tse entsweng ka polasetiki ka DPHP di bontsha ho kwahela motlakase ho hoholo, ho hanyetsa boemo ba lehodimo, ho feto-fetoha ho tlase, le thepa e tlase ya physico-chemical, e leng se etsang hore di sebetse haholo ka dithapo, disebedisweng tsa ka tlung, difiliming tsa dikarolo tsa dikoloi le dipolasetiking tsa fatshe. Ho feta moo, 2-PH e ka sebediswa ho kopanya di-surfactant tse sebetsang hantle tse seng tsa ionic. Ka 2012, BASF le Sinopec Yangzi Petrochemical ba ile ba kopanngwa ka kopanelo setsing sa tlhahiso ya 2-PH ya ditone tse 80,000 ka selemo, e leng semela sa pele sa China sa 2-PH. Ka 2014, Shenhua Baotou Coal Chemical Company e ile ya qala yuniti ya tlhahiso ya 2-PH ya ditone tse 60,000 ka selemo, projeke ya pele ya 2-PH e thehilweng mashaleng China. Hajoale, lik'hamphani tse 'maloa tse nang le merero ea mashala ho tloha ho olefin li rera lits'ebeletso tsa 2-PH, ho kenyeletsoa Yanchang Petroleum (lithane tse 80,000 ka selemo), China Coal Shaanxi Yulin (lithane tse 60,000 ka selemo), le Inner Mongolia Daxin (lithane tse 72,700 ka selemo).
INA e sebediswa haholoholo ho hlahisa diisononyl phthalate (DINP), e leng plasticizer ya bohlokwa e sebediswang ka kakaretso. Lekgotla la Matjhaba la Diindasteri tsa Dipapadi le nkile DINP e se kotsi ho bana, mme tlhoko ya yona e ntseng e hola dilemong tsa morao tjena e bakile tshebediso e eketsehileng ya INA. DINP e sebediswa haholo makaleng a dikoloi, dikheibole, fatshe, kaho le mafapheng a mang a indasteri. Ka Mphalane 2015, kgwebo ya kopanelo ya 50:50 pakeng tsa Sinopec le BASF e qadile ka molao tlhahiso fekthering ya INA ya ditone tse 180,000 ka selemo Maoming, Guangdong—e leng yona feela setsi sa tlhahiso ya INA Chaena. Tshebediso ya malapeng e eme ho ditone tse ka bang 300,000, e leng se siileng lekhalo la phepelo. Pele ho projeke ena, Chaena e ne e itshetlehile ka ho feletseng ka thepa e tswang kantle ho naha bakeng sa INA, ka ditone tse 286,000 tse kentsweng ka 2016.
Ka bobeli 2-PH le INA li hlahisoa ka ho kopanya li-butene tse tsoang melapong ea C4 le syngas (H₂ le CO2). Ts'ebetso ena e sebelisa li-catalyst tse rarahaneng tsa tšepe e ntle, 'me tlhahiso le khetho ea li-catalyst tsena e ntse e le litšitiso tsa bohlokoa tlhahisong ea 2-PH le INA ea lapeng. Lilemong tsa morao tjena, litsi tse 'maloa tsa lipatlisiso tsa Chaena li hatetse pele theknolojing ea tlhahiso ea INA le nts'etsopele ea li-catalyst. Mohlala, Laboratori ea K'hemistri ea C1 ea Tsinghua University e sebelisitse li-octene tse tsoakiloeng tse tsoang ho butene oligomerization e le lijo le catalyst ea rhodium e nang le triphenylphosphine oxide e le ligand, e fihlella chai ea 90% ea isononanal, e fanang ka motheo o tiileng oa ho holisa indasteri.
