Owasekhayai-butyl acetateimakethe ingene enkathini ebiza kakhulu kusukela ngo-2021 kuya phambili.Kumakhasimende okugcina, akunakugwenywa ukugwema izinto zokusetshenziswa ezinenani eliphezulu futhi usebenzise ezinye izindlela ezingabizi.Ngakho-ke i-sec-butyl acetate, i-propyl acetate, i-propylene glycol methyl ether, i-dimethyl carbonate, njll. konke kunomthelela emakethe ye-butyl acetate.Uhlangothi lwetheminali lukhetha ukushintshwa ngokusekelwe ekusebenzeni kwezinhlobo ezahlukene zemikhiqizo, okuholele ekwehleni okukhulu kwesidingo se-butyl acetate eminyakeni emibili edlule.ukusetshenziswa kwasekhaya kwe-butyl acetate kwehle kwafinyelela kumathani angama-400,000 ngo-2021, kwehle kwafika ezingeni lesikhathi sika-2016.Nakuba kunomthelela wesici sobhubhane, kungenxa yezindleko eziphezulu kanye nenani eliphezulu eliholela ekuncipheni kwe-butyl acetate ekugcineni ukusetshenziswa.

Engxenyeni yokuqala ka-2022, imakethe yasekhaya ye-butyl acetate yonke yanyakaza yehla, futhi kusukela ngomhla ka-13 Julayi, intengo yemakethe evamile eNyakatho neChina yayingu-7,400-7450 yuan/ton, kanti intengo yemakethe emaphakathi ibizwa ngokuthi ukwehla ngo-19.29%. ekupheleni konyaka odlule.Amakhemikhali alula emhlabeni jikelele wokuthengwa kwezinto ezibonakalayo kanye nenkundla yokuthengisa, ehlinzeka nge-acetic acid, i-n-butanol, ukuthengiswa kwezinto ezingavuthiwe ze-butyl acetate.

Ikota yokuqala: ukuhweba ezimakethe kulula futhi amanani ayehla

NgoJanuwari, inkambiso iyonke ye-butyl acetate yalandela ukukhuphuka kwezinto zokusetshenziswa i-n-butanol, kwase kuthi eduze noMkhosi Wasentwasahlobo kuholele emikhawulweni yezokuthutha, ukuthengiselana kwemakethe kwehle.

NgoFebhuwari, amanani aqala ukukhuphuka ngemuva kokuvulwa kwemakethe ngemuva koNyaka Omusha WaseShayina, impahla eluhlaza iphela i-n-butanol ngoba abanye abathengi bagcwalisa izikhundla zabo ngemuva komkhosi, ukushoda kwendawo, futhi iningi labanikazi bamasheya bahawukela ukuthengisa, ngakho intengo yaphinde yagcwala ibhodi.

Ekuqaleni kuka-March, eqhutshwa amanani kawoyela ongahluziwe, amanani e-methanol akhuphuka ngokushesha, amanani e-acetic acid akhuphuka kakhulu, futhi amanani e-n-butanol ayeqinile, asekelwa izindleko, amanani e-butyl acetate alandela ukukhuphuka, maphakathi nenyanga ngenxa ubhubhane, isidingo esingezansi komfula kanye nokuphazamiseka kwethrafikhi ezindaweni eziningi, ukuhweba ezimakethe kulula, amanani okuthenga emakethe ayaqhubeka nokwehla.

Ikota yesibili: inkambiso iyonke ye-oscillation encane

Ngaphambi kweholide likaMeyi Day, ukugcwaliswa kabusha komfula, futhi abanye abakhiqizi be-acetic acid banezinhlelo zokuyinakekela, amanani e-acetic akhuphuka, izindleko zokusekela, amanani e-butyl acetate alandela ukukhuphuka.

NgoJuni, izintengo ze-n-butanol ziqhubekile nokuthamba, okuhambisana nokwehla okuqhubekayo kwezintengo ze-acetic acid yezinto ezingavuthiwe, ngaphansi kwethonya lokusekelwa kwezindleko ezinganele, amanani e-butyl acetate aqhubeka nokulandela ukwehla.

NgoJulayi, intengo ye-butyl acetate iyaqhubeka nokuba buthaka, i-acetic acid ne-n-butanol yezinto ezingavuthiwe ayinamandla, ukusekelwa kwezindleko akwanele, futhi isidingo sisonke se-lowstream silula uma kuqhathaniswa, ukuthengwa kokuningi ukuze kugcinwe isidingo nje, Umkhathi wokuhweba ensimini ujwayelekile, uhlangothi lwempahla eluhlaza kulindeleke ukuba lube buthaka, kuyilapho uhlangothi lwesidingo lwezansi nomfula ukuze kugcinwe isidingo nje, isimo sengqondo senkundla sijwayelekile, umthelela wokunikezwa okubuthakathaka kanye nesidingo, kulindeleke ukuthi isikhashana esifushane imakethe ye-butyl acetate noma iqhubeka nokuba buthakathaka, sekwephuzile kusadingeka ukunaka amandla e-dynamics yedivayisi yabakhiqizi Kulindeleke ukuthi imakethe yasekhaya ye-butyl acetate izohlala ibuthakathaka esikhathini esifushane.
