Ugbu a, ihe ndị a na-ejikarị eme ihe bụ 2-propylheptanol (2-PH) na isononyl alcohol (INA), nke a na-ejikarị eme ihe n'imepụta ihe ndị na-emepụta plastik ọhụrụ. Esters e ji ihe ndị dị elu dịka 2-PH na INA mepụta na-enye nchekwa na ịdị mma gburugburu ebe obibi.
2-PH na-emeghachi omume na phthalic anhydride iji mepụta di(2-propylheptyl) phthalate (DPHP). Ngwaahịa PVC ejiri DPHP mee plastik na-egosipụta mkpuchi eletriki dị elu, iguzogide ihu igwe, obere mgbanwe, na obere ihe onwunwe physico-chemical, na-eme ka ha dabara adaba na waya, ngwa ụlọ, ihe nkiri akụrụngwa ụgbọala, na plastik ala. Na mgbakwunye, enwere ike iji 2-PH mepụta ihe ndị na-abụghị ionic surfactants dị elu. Na 2012, BASF na Sinopec Yangzi Petrochemical jikọrọ aka rụọ ọrụ ebe mmepụta 2-PH nke tọn 80,000 kwa afọ, ụlọ ọrụ mbụ China nke nwere PH 2. Na 2014, Shenhua Baotou Coal Chemical Company malitere ngalaba mmepụta PH nke tọn 60,000 kwa afọ, ọrụ PH 2 nke mbụ nke China. Ugbu a, ọtụtụ ụlọ ọrụ nwere ọrụ kol site na iji olefin na-eme atụmatụ maka ebe abụọ nwere PH, gụnyere Yanchang Petroleum (ton 80,000/afọ), China Coal Shaanxi Yulin (ton 60,000/afọ), na Inner Mongolia Daxin (ton 72,700/afọ).
A na-ejikarị INA emepụta diisononyl phthalate (DINP), ihe dị mkpa maka imepụta plastik n'ozuzu. Òtù Mba Nile nke Ụlọ Ọrụ Ihe Ntụrụndụ Egwuregwu ewerela DINP dị ka ihe na-adịghị ize ndụ nye ụmụaka, ọchịchọ ya na-eto eto n'afọ ndị na-adịbeghị anya emeela ka oriri INA mụbaa.

Na Ọktoba 2015, otu ọrụ jikọrọ Sinopec na BASF malitere mmepụta n'ihu ọha na ụlọ ọrụ INA nke na-eru tọn 180,000 kwa afọ na Maoming, Guangdong—naanị ụlọ ọrụ mmepụta INA na China.
