Codsiyada suuqa ee khamriga caaga ah

Waqtigan xaadirka ah, alkolada balaastikada ah ee aadka loo isticmaalo waa 2-propylheptanol (2-PH) iyo aalkolada isononyl (INA), ugu horrayn waxaa lagu dabaqaa soosaarka balaastiijiyeyaasha soo socda. Esters-ka laga sameeyay aalkolada sare sida 2-PH iyo INA waxay bixiyaan badbaado badan iyo saaxiibtinimo deegaanka.

2-PH waxay la falgashaa phthalic anhydride si ay u sameyso di(2-propylheptyl) phthalate (DPHP). Alaabooyinka PVC ee lagu balaariyay DPHP waxay muujinayaan dahaar sare oo koronto ah, iska caabin cimilo, isbeddel hoose, iyo sifooyinka kiimikaad ee hooseeya, taasoo ka dhigaysa inay si weyn u dabaqaan fiilooyinka, qalabka guriga, filimada baabuurta, iyo balaastikada sagxadda. Intaa waxaa dheer, 2-PH waxaa loo isticmaali karaa in lagu soo saaro wax qabad sare oo ujeedo guud oo aan ahayn wax-soo-saarka. Sannadkii 2012, BASF iyo Sinopec Yangzi Petrochemical ayaa si wadajir ah u wakiishay 80,000-ton-sanadkiiba 2-PH xarun wax-soo-saar ah, warshaddii ugu horreysay ee Shiinaha ee 2-PH. Sannadkii 2014-kii, Shirkadda Kiimikada Dhuxusha ee Shenhua Baotou waxay bilawday 60,000-ton-sanadkiiba unug wax-soo-saar 2-PH ah, mashruucii ugu horreeyay ee Shiinaha ee 2-PH-ku-salaysan dhuxusha. Waqtigan xaadirka ah, shirkado dhowr ah oo leh mashruucyo dhuxul-olefin ah ayaa qorsheynaya xarumaha 2-PH, oo ay ku jiraan Yanchang Petroleum (80,000 tons / year), China Coal Shaanxi Yulin (60,000 tons / year), iyo Inner Mongolia Daxin (72,700 tons / year).

INA waxaa inta badan loo isticmaalaa in lagu soo saaro diisononyl phthalate (DINP), balaastik ujeedo guud oo muhiim ah. Golaha Caalamiga ah ee Warshadaha Caruusadu waxay u arkeen DINP mid aan khatar ku ahayn carruurta, iyo baahideeda sii kordheysa ee sannadihii la soo dhaafay ayaa horseeday kororka isticmaalka INA. DINP waxaa si weyn loogu isticmaalaa baabuurta, fiilooyinka, sagxadaha, dhismaha, iyo qaybaha kale ee warshadaha. Bishii Oktoobar 2015, 50:50 iskaashi ah oo u dhexeeya Sinopec iyo BASF ayaa si rasmi ah u bilaabay wax soo saarka warshad 180,000-tan-sanad ah INA ah oo ku taal Maoming, Guangdong - oo ah xarunta kaliya ee INA ee Shiinaha. Isticmaalka gurigu wuxuu taagan yahay qiyaastii 300,000 oo tan, taasoo ka tagaysa farqiga saadka. Mashruucan ka hor, Shiinuhu wuxuu gebi ahaanba ku tiirsanaa soo dejinta INA, iyadoo 286,000 oo tan la soo dejiyay 2016.

Labada 2-PH iyo INA waxaa lagu soo saaraa ka falcelinta butenes ee durdurrada C4 ee leh syngas (H₂ iyo CO). Hannaanku waxa uu shaqaalaysiiyaa biraha qaaliga ah ee isku dhafan, iyo isku-dhafka iyo xulashada kicinyaashan ayaa weli ah caqabadaha muhiimka ah ee wax soo saarka gudaha 2-PH iyo INA. Sanadihii la soo dhaafay, dhowr machadyada cilmi-baarista Shiinaha ayaa horumar ka sameeyay tignoolajiyada wax soo saarka ee INA iyo horumarinta kicinta. Tusaale ahaan, Jaamacadda Tsinghua's C1 Chemistry Laboratory waxay isticmaashay octenes isku dhafan oo ka soo jeeda butene oligomerization sida feedstock iyo kicinta rhodium ee leh triphenylphosphine oxide sida ligand, taasoo gaadhaysa 90% soosaarka isononanal, taasoo bixisa aasaas adag oo kor u qaadida warshadaha.
