1,Iyo yakazara mutengo wekuwedzera mune phenolic ketone indasitiri chain

Vhiki rapfuura, mutengo wekutapurirana we phenolic ketone indasitiri chain yaive yakatsetseka, uye mitengo zhinji yechigadzirwa yakaratidza kukwira kumusoro. Pakati pavo, kuwedzera kweacetone kwainyanya kukosha, kusvika ku2.79%. Izvi zvinonyanya kukonzerwa nekudzikira kwekupihwa kwemusika wepropylene uye rutsigiro rwakasimba rwemutengo, zvichikonzera kuwedzera kwenhaurirano dzemusika. Kuremerwa kwekushanda kwemafekitori emumba acetone ishoma, uye zvigadzirwa zvinoiswa pamberi pekupa pasi pemvura. Iko kutenderera kwakasimba mumusika kunowedzera kukwidza mitengo.

2,Tight kupa uye kushanduka kwemitengo mumusika weMMA

Kusiyana nezvimwe zvigadzirwa muketani yeindasitiri, mutengo wepakati weMMA wakaramba uchiderera svondo rapfuura, asi mutengo wemazuva ese wakaratidza kuderera kwekutanga uchiteverwa nekuwedzera. Izvi zvinokonzerwa nekusarongeka kwekugadziriswa kwemamwe maturusi, zvichikonzera kudzikira kweMMA chiyero chemutoro uye kuwanda kwezvinhu zvepamusika. Nekuwedzera mari yekutsigira, mitengo yemusika yakakwira. Chiitiko ichi chinoratidza kuti kunyangwe mitengo yeMMA ichikanganiswa nekushomeka kwekupa munguva pfupi, mutengo uchiri kutsigira mitengo yemusika.

3, Mutengo Wekufambisa Kuongorora kwePure Benzene Phenol Bisphenol A Chain

Mune yakachena benzene phenol bisphenol A cheni, mutengo wekufambisa

mhedzisiro ichiri yakanaka. Kunyangwe pure benzene yakatarisana netarisiro isina tariro yekuwedzera kugadzirwa muSaudi Arabia, kushomeka kwekutanga uye kusvika kwakazotevera pachiteshi chikuru chechiteshi chengarava muEast China zvakakonzera kunetsa kwemusika uye kukwidza mitengo. Iko kushandurwa kwemutengo kwe phenol uye kumusoro kwe pure benzene kwasvika padanho idzva gore rino, ine mutengo wakasimba wekusimudzira. Iyo isina kukwana nzvimbo inotenderera yebisphenol A, pamwe nekumanikidzwa kwemutengo, inoumba rutsigiro rwemitengo kubva kumutengo uye mativi ekupa. Zvisinei, kuwedzera kwemutengo wepasi kuduku pane kukura kwezvinhu zvakasvibiswa, zvichiratidza kuti kutapurirana kwemutengo kuzasi kunotarisana nezvimwe zvipingamupinyi.

3,Yakazara purofiti yeiyo phenolic ketone indasitiri chain

Kunyange zvazvo mutengo wakazara we phenolic ketone industry chain wawedzera, iyo yose purofiti mamiriro haasati aita tariro. The theoretical loss of phenol ketone co production is 925 yuan / ton, asi ukuru hwekurasikirwa kwakaderera kana kuenzaniswa nevhiki yapfuura. Izvi zvinonyanya kukonzerwa nekuwedzera kwemitengo ye phenol uye acetone, uye kuwedzera kukuru kwese kuenzaniswa neyakagadzirwa yakachena benzene uye propylene, zvichikonzera purofiti yakawedzera zvishoma. Zvisinei, zvigadzirwa zvepasi zvakadai sebisphenol A zvakashanda zvisina kunaka maererano nekubudirira, nekurasikirwa kwezvinyorwa zve 964 yuan / ton, kuwedzera kwehukuru hwekurasikirwa kuenzaniswa nevhiki yapfuura. Nokudaro, zvakakosha kubhadhara kana pane zvirongwa zvekuderedza kugadzirwa uye kuvhara phenol ketone uye bisphenol A units muchikamu chekupedzisira.

4,Kuenzanisa purofiti pakati peacetone hydrogenation nzira isopropanol uye MMA

Muzvigadzirwa zvakaderera zveacetone, purofiti yeacetone hydrogenation isopropanol yakadzikira zvakanyanya, neavhareji yetioretical gross purofiti ye -260 yuan/ton svondo rapfuura, mwedzi pamwedzi kudzikira kwe50.00%. Izvi zvinonyanya kukonzerwa nemutengo wepamusoro weacetone yakasvibirira uye kuwedzera kudiki kwemitengo yakadzika yeisopropanol. Mukupesana, kunyangwe mutengo uye purofiti margin yeMMA yadzikira, ichiri kuchengetedza purofiti yakasimba. Vhiki rapfuura, iyo indasitiri yeavhareji theoretical gross purofiti yaive 4603.11 yuan/ton, inova chinhu chinonyanya kuita purofiti mune phenolic ketone industry chain.
