Le aigabutyl acetatemaketi ua ulufale atu i le tau maualuga mai le 2021 agai i luma. Mo fa'atauga fa'ai'uga, e le maalofia le aloese mai mea mata'utia taugata ma fa'aaoga isi mea taugofie. O lea la sec-butyl acetate, propyl acetate, propylene glycol methyl ether, dimethyl carbonate, ma isi mea uma e aʻafia ai le maketi o le butyl acetate. E filifilia e le pito i tua le sui e fa'atatau i le fa'atinoina o ituaiga oloa eseese, lea na mafua ai le pa'u tele o le mana'oga mo le butyl acetate i le lua tausaga talu ai. O le taumafaina i totonu o le atunuu o le butyl acetate na paʻu i le 400,000 tone i le 2021, i lalo i le maualuga o le 2016 taimi faʻatulagaina. E ui lava o loʻo i ai le aʻafiaga o le faʻamaʻi pipisi, e sili atu ona o le tau maualuga ma le tau maualuga e mafua ai le faʻaitiitia o le butyl acetate i le faʻaaogaina.

I le afa muamua o le 2022, o le maketi o le butyl acetate i totonu o le atunuʻu atoa na teteʻe i lalo, ma e oʻo mai ia Iulai 13, o le tau o maketi i North China o le 7,400-7450 yuan / ton, ma le tau ogatotonu o maketi ua taʻua o le 19.29% pa'ū i le faaiuga o le tausaga talu ai. Fa'atauga fa'atauga ma fa'atauga fa'atau, tu'uina atu acetic acid, n-butanol, butyl acetate fa'atau mea mata.

Kuata muamua: o fefaʻatauaʻiga maketi e mama ma o tau o loʻo pa'ū

Ia Ianuari, o le aotelega o le butyl acetate na sosoʻo ai ma le faʻatupulaia o mea mataʻutia n-butanol, ona lata ane lea i le Spring Festival na taʻitaʻia ai le faʻatapulaʻaina o logistics, faʻaititia fefaʻatauaiga o maketi.

Ia Fepuari, na amata ai ona siitia tau ina ua maeʻa le maketi o le Tausaga Fou a Saina, o mea mataʻutia e muta ai le n-butanol ona o nisi tagata faʻatau e toe faʻatumu o latou tulaga pe a maeʻa le tausamiga, vaʻaia le utiuti, ma le toʻatele o le au fai sea e alolofa e faʻatau atu, o lea na toe oso ai le tau i luga o le laupapa.

I le amataga o Mati, ona o le tau o le suauu mama, o le tau o le methanol na vave ona siitia, o le acetic acid ua maualuga le tau, ma o le tau o le n-butanol na mausali, na lagolagoina e le tau, o le tau o le butyl acetate na sosoo ai ma le siʻitia, i le ogatotonu o le masina ona o le faʻamaʻi, manaoga i lalo ma faʻalavelave feoaiga i le tele o nofoaga, o fefaʻatauaʻiga tau maketi o loʻo faʻaauau pea ona faʻaitiitia.

Kuata lona lua: o le tulaga lautele o le vaapiapi oscillation

Aʻo leʻi oʻo i le aso malolo o Me, toe faʻaleleia i lalo, ma nisi o gaosiga o le acetic acid o loʻo i ai fuafuaga faʻaleleia, o le tau o le acetic acid na siʻitia, o le tau o le lagolago, o le butyl acetate tau na mulimulitaʻi i luga.

Ia Iuni, na faʻaauau pea ona faʻamaluluina tau o le n-butanol, faʻatasi ai ma le faʻaauau pea o le faʻaitiitia o tau o meafaitino acetic acid, i lalo o le faatosinaga o le le lava lagolago tau, o le butyl acetate tau na faʻaauau pea ona mulimuli i le paʻu.

Ia Iulai, o le tau o le butyl acetate o loʻo faʻaauau pea ona vaivai, o meafaitino acetic acid ma le n-butanol e vaivai, o le tau e le lava, ma o le aofaʻi o le manaʻoga i lalo e mama tele, o le faʻatauga o mea e sili atu e tausia ai le manaʻoga, o le siosiomaga fefaʻatauaʻiga lautele, o le itu o mea mata e faʻamoemoe e faʻavaivaia, ae o le itu manaʻomia o le pito i lalo e faʻatumauina ai le manaʻoga, o le tulaga o le mafaufau o loʻo faʻamoemoeina, o le aʻafiaga o le lotoifale e lautele ma le faʻamoemoeina o le manaʻoga. maketi poʻo faʻaauau pea ona vaivai, e manaʻomia pea e le tuai ona gauai atu i le malosi o le gaosiga o masini E faʻamoemoeina o le a tumau pea le vaivai o le maketi o le butyl acetate i se taimi pupuu.
