Ngwa ahịa nke Plasticizer mmanya

Ugbu a, ihe ndị a na-ejikarị plasticizer alcohols bụ 2-propylheptanol (2-PH) na mmanya isononyl (INA), nke a na-etinyekarị na mmepụta nke ndị na-emepụta plastik na-esote. Esters synthesized sitere na mmanya dị elu dị ka 2-PH na INA na-enye nchekwa dị ukwuu na enyi gburugburu ebe obibi.

2-PH na-emeghachi omume na phthalic anhydride iji mepụta di(2-propylheptyl) phthalate (DPHP). Ngwaahịa PVC plasticized na DPHP na-egosipụta mkpuchi ọkụ eletrik dị elu, nguzogide ihu igwe, mgbanwe dị ala, na akụrụngwa physico-kemịkalụ dị ala, na-eme ka ha dị n'ọtụtụ ebe na eriri, ngwa ụlọ, ihe nkiri akụrụngwa ụgbọ ala, na plastik ala. Tụkwasị na nke a, enwere ike iji 2-PH mee ihe na-arụ ọrụ dị elu na-arụ ọrụ izugbe na-enweghị isi. N'afọ 2012, BASF na Sinopec Yangzi Petrochemical jikọtara ọnụ ụlọ ọrụ mmepụta 2-PH nke 80,000-ton kwa afọ, ụlọ ọrụ 2-PH mbụ nke China. N'afọ 2014, Shenhua Baotou Coal Chemical Company weputara ngalaba mmepụta 2-PH nke 60,000 kwa afọ, ọrụ 2-PH mbụ nke China sitere na coal. Ugbu a, ọtụtụ ụlọ ọrụ na coal-to-olefin oru na-eme atụmatụ 2-PH ụlọ ọrụ, gụnyere Yanchang Petroleum (80,000 tọn / afọ), China Coal Shaanxi Yulin (60,000 tọn / afọ), na Inner Mongolia Daxin (72,700 tọn / afọ).

A na-ejikarị INA emepụta diisononyl phthalate (DINP), plasticizer dị mkpa maka izugbe. Otu International Council of Toy Industries ewerewo DINP adịghị ize ndụ nye ụmụaka, na ọchịchọ ya na-eto eto n'afọ ndị na-adịbeghị anya emeela ka INA dịkwuo elu. A na-eji DINP eme ihe n'ọtụtụ ebe na ụgbọ ala, eriri, ala ala, ihe owuwu, na ngalaba mmepụta ihe ndị ọzọ. Na October 2015, a 50: 50 nkwonkwo venture n'etiti Sinopec na BASF eze malitere mmepụta na 180,000-ton-kwa afọ INA osisi na Maoming, Guangdong-naanị INA mmepụta eweta na China. Oriri ụlọ dị ihe dị ka tọn 300,000, na-ahapụ oghere ọkọnọ. Tupu oru ngo a, China dabere kpamkpam na mbubata maka INA, na mbubata tọn 286,000 na 2016.

A na-emepụta ma 2-PH na INA site na mmeghachi omume butene sitere na iyi C4 nwere syngas (H₂ na CO). Usoro a na-eji ezigbo metal complex catalysts, na njikọ na selectivity nke ihe ndị a na-akpali akpali na-anọgide bụ isi bottlenecks na anụ ụlọ 2-PH na INA mmepụta. N'ime afọ ndị na-adịbeghị anya, ọtụtụ ụlọ ọrụ nyocha nke China enweela ọganihu na teknụzụ mmepụta INA na mmepe mmepe. Dịka ọmụmaatụ, ụlọ nyocha nke Mahadum Tsinghua C1 Chemistry Laboratory jiri octenes agwakọta sitere na butene oligomerization dị ka nri nri na ihe na-eme ka rhodium nwere triphenylphosphine oxide dị ka ligand, na-enweta mkpụrụ nke isononanal 90%, na-enye ntọala siri ike maka mmụba ụlọ ọrụ.
