Kwiveki ephelileyo, iimveliso ezingama-31 kwizixhobo eziphambili zeekhemikhali zinyukile, zibanga i-28.44%; iimveliso ezingama-31 bezizinzile, zibanga i-28.44%; iimveliso ezingama-47 zinciphile, zibanga i-43.12%.
Iimveliso ezintathu eziphambili zokunyuka yi-MDI, i-pure MDI, kunye ne-butadiene, ene-5.73%, 5.45%, kunye ne-5.07%;
Iimveliso ezintathu eziphambili yayiyi-chlorine engamanzi, i-carbonate, kunye neoyile yepetroli, kwaye ukwehla kwaba yi-28.57%, 8.00%, kunye ne-6.60%, ngokulandelelana.
Ixabiso le-oyile ekrwada: NgoFebruwari 2023 i-WTI inyuke nge-2.07 $79.56 / BBL, inyuke nge-2.67%; NgoFebruwari 2023 iBrent inyuke nge-2.94, okanye i-3.6%, yaya kwi-$83.92 ngebhereli. I-China crude oil futures SC main 2302 ivale nge-0.7 yuan/ibhereli ukuya kwi-547.7 yuan/ibhereli.
I-Butanone: Ukusukela ngoLwesine, ixabiso eliqhelekileyo leveki lemarike ye-butanone eMpuma China beliyi-8160 yuan/ton, lehle kancinci nge-1.81% xa kuthelekiswa neveki ephelileyo. Iveki ezayo kukuphela konyaka, imfuno yemarike ye-butyl ketone yasekhaya kulindeleke ukuba iqhubeke nokuba buthathaka, inani leefektri zasekhaya ezisezantsi nezisezantsi ekupheleni konyaka linyukile, imeko-bume yorhwebo lwemarike iyonke kulindeleke ukuba ihlale ibuthathaka. Kodwa okwangoku, ixabiso lemarike lilonke liphinde lehla ngaphantsi komsebenzi weendleko, indawo esezantsi ayinkulu, kulindeleke ukuba ibe buthathaka kakhulu ekuhlanganisweni kwemarike kwiveki ezayo.
