I tēnei wā, ko ngā waipiro whakapūmau kirihou e whakamahia whānuitia ana ko te 2-propylheptanol (2-PH) me te waipiro isononyl (INA), e whakamahia whānuitia ana i roto i te hanga o ngā whakapūmau kirihou o te whakatupuranga e whai ake nei. Ko ngā esters i hangaia mai i ngā waipiro teitei ake pērā i te 2-PH me te INA ka nui ake te haumaru me te atawhai ki te taiao.
Ka tauhohe te 2-PH ki te phthalic anhydride hei hanga i te di(2-propylheptyl) phthalate (DPHP). Ko ngā hua PVC kua whakakikoruatia ki te DPHP he pai ake te ārai hiko, te ātete ki te huarere, te iti o te piki me te heke, me ngā āhuatanga ā-tinana-matū iti, e whai hua whānuitia ana i roto i ngā taura, ngā taputapu whare, ngā kiriata wāhanga motuka, me ngā kirihou papa. Hei tāpiri, ka taea te whakamahi i te 2-PH hei hanga i ngā surfactants kore-ionic whānui-mahi-teitei. I te tau 2012, i mahi tahi a BASF me Sinopec Yangzi Petrochemical ki te whakatū i tētahi whare hanga 2-PH 80,000-tana-ia-tau, te tipu 2-PH tuatahi o Haina. I te tau 2014, i whakarewahia e Shenhua Baotou Coal Chemical Company tētahi wāhanga hanga 2-PH 60,000-tana-ia-tau, te kaupapa 2-PH waro tuatahi o Haina. I tēnei wā, kei te whakamahere ētahi kamupene me ngā kaupapa waro-ki-olefin i ngā whakaurunga 2-PH, tae atu ki a Yanchang Petroleum (80,000 tana/tau), China Coal Shaanxi Yulin (60,000 tana/tau), me Inner Mongolia Daxin (72,700 tana/tau).
Ko te INA te mea nui e whakamahia ana hei hanga i te diisononyl phthalate (DINP), he mea hanga kirihou whānui. Kua whakaarohia e te Kaunihera o Ngā Ahumahi Taonga Tākaro o te Ao he mea kino te DINP ki ngā tamariki, ā, ko te pikinga o te hiahia i ngā tau tata nei kua piki ake te whakamahinga o te INA. He whānui te whakamahinga o te DINP i roto i ngā rāngai motuka, taura, papa, hanga whare, me ētahi atu rāngai ahumahi. I te marama o Oketopa 2015, i tīmata mana te mahi tahi 50:50 i waenganui i a Sinopec me BASF ki te whakaputa i tētahi tipu INA 180,000 tana ia tau i Maoming, Guangdong—koinei anake te whare whakaputa INA i Haina. Ko te whakamahinga ā-whare kei te tata ki te 300,000 tana, ka waiho he āputa tuku. I mua i tēnei kaupapa, i whakawhirinaki katoa a Haina ki ngā kawemai mō te INA, me te 286,000 tana i kawemai i te tau 2016.
Ka puta te 2-PH me te INA mā te tauhohenga i ngā butene mai i ngā awa C4 me ngā syngas (H₂ me te CO). Ka whakamahia e te tukanga ngā whakakorikori matū whakarewa rangatira, ā, ko te hanganga me te whiriwhiringa o ēnei whakakorikori he arai matua tonu i roto i te hanga 2-PH me te INA ā-whare. I ngā tau tata nei, he maha ngā whare rangahau Hainamana kua ahu whakamua i roto i te hangarau hanga INA me te whanaketanga o ngā whakakorikori. Hei tauira, i whakamahia e te C1 Chemistry Laboratory o Te Whare Wānanga o Tsinghua ngā octene whakaranu mai i te oligomerization butene hei rauemi whāngai me te whakakorikori rhodium me te triphenylphosphine oxide hei ligand, ka tutuki he 90% o te isononanal, e whakarato ana i te turanga pakari mō te whakanui ake i te ahumahi.
