Parizvino, maalcohols epurasitiki anonyanya kushandiswa i2-propylheptanol (2-PH) uye isononyl alcohol (INA), anonyanya kushandiswa mukugadzira mapurasitiki echizvarwa chinotevera. MaEsters anogadzirwa kubva kualcohols akakwira akadai se2-PH neINA anopa kuchengetedzeka kwakanyanya uye hushamwari kune nharaunda.
2-PH inoshanda pamwe chete nephthalic anhydride kugadzira di(2-propylheptyl) phthalate (DPHP). Zvigadzirwa zvePVC zvakagadzirwa nepurasitiki neDPHP zvinoratidza kudzikamisa kwemagetsi kwepamusoro, kuramba mamiriro ekunze, kusagadzikana kwakaderera, uye hunhu hushoma hwe physico-chemical, zvichiita kuti zvishandiswe zvakanyanya mutambo, midziyo yemumba, mafirimu ezvikamu zvemotokari, uye mapurasitiki epasi. Pamusoro pezvo, 2-PH inogona kushandiswa kugadzira ma surfactants anoshanda zvakanyanya. Muna 2012, BASF neSinopec Yangzi Petrochemical vakabatana vakapa nzvimbo yekugadzira 2-PH ye80,000-ton-pagore, chirimwa chekutanga che2-PH muChina. Muna 2014, Shenhua Baotou Coal Chemical Company yakatanga unit yekugadzira 2-PH ye60,000-ton-pagore, chirongwa chekutanga che2-PH cheChina chakavakirwa pamalahle. Parizvino, makambani akati wandei ane mapurojekiti ekugadzira marasha kubva kuOlefin ari kuronga zvivakwa zve2-PH, zvinosanganisira Yanchang Petroleum (matani 80,000 pagore), China Coal Shaanxi Yulin (matani 60,000 pagore), uye Inner Mongolia Daxin (matani 72,700 pagore).
INA inonyanya kushandiswa kugadzira diisononyl phthalate (DINP), chinhu chakakosha chepurasitiki chinoshandiswa pakugadzira zvinhu. Dare reInternational Council of Toy Industries rakaona DINP isina njodzi kuvana, uye kudiwa kwayo kuri kukura mumakore achangopfuura kwakaita kuti kushandiswa kweINA kuwedzere. DINP inoshandiswa zvakanyanya mumotokari, tambo, pasi, kuvaka, nedzimwe nzvimbo dzemaindasitiri. Muna Gumiguru 2015, mubatanidzwa we50:50 pakati peSinopec neBASF wakatanga zviri pamutemo kugadzira pafekitori yeINA inosvika matani 180,000 pagore muMaoming, Guangdong—nzvimbo yega yekugadzira INA muChina. Kushandiswa kwemumba kuri matani angangoita 300,000, zvichisiya mukaha wekupa. Basa iri risati raitwa, China yaivimba nekutenga zvinhu zvinotengeswa kunze kwenyika zveINA, nematani 286,000 akaunzwa muna 2016.
Zvese 2-PH neINA zvinogadzirwa nekuita mabutenes kubva kuC4 streams ne syngas (H₂ neCO2). Maitiro aya anoshandisa noble metal complex catalysts, uye kugadzirwa nekusarudzwa kwema catalysts aya kunoramba kuri zvikanganiso zvikuru mukugadzirwa kwe2-PH neINA. Mumakore achangopfuura, masangano akati wandei ekutsvagisa ekuChina akafambira mberi mukugadzirwa kwetekinoroji yeINA uye kuvandudzwa kwema catalyst. Semuenzaniso, Tsinghua University's C1 Chemistry Laboratory yakashandisa mixed octenes kubva ku butene oligomerization se feedstock uye rhodium catalyst ine triphenylphosphine oxide se ligand, zvichiwana goho re90% re isononanal, zvichipa hwaro hwakasimba hwekusimudzirwa kwemaindasitiri.
