Popindula ndi chitukuko chofulumira cha mafakitale akumunsi, dziko langa lakhala dziko lomwe limapanga p-chlorotoluene padziko lonse lapansi.Kuphatikiza pa kukwaniritsa zosowa za msika wapakhomo, zogulitsazo zimatumizidwanso kumisika yakunja.
p-Chlorotoluene, yomwe imadziwikanso kuti 4-chlorotoluene, ili ndi formula ya molekyulu C7H7Cl.Maonekedwe a p-chlorotoluene ndi madzi opanda mtundu komanso owoneka bwino, okhala ndi fungo lapadera, kawopsedwe komanso kupsa mtima.p-Chlorotoluene ndi yosasungunuka m'madzi, sungunuka mu zosungunulira organic monga mowa, etha, benzene, acetone, chloroform, ndi zina zotero. Ndi yoyaka, kuyaka ngati lawi lotseguka, amachita mwachiwawa ngati oxidizing agent, ndipo akhoza kuphulika mu mpweya. zotengera.Para-chlorotoluene ndiye mtundu wofunikira kwambiri pakati pa ma isomers atatu a chlorotoluene.
Kukonzekera njira za p-chlorotoluene makamaka monga toluene onunkhira mphete chlorination njira, p-toluidine diazotization njira ndi zina zotero.Mwa iwo, toluene onunkhira mphete chlorination njira ndi ambiri kukonzekera ndondomeko.Amagwiritsa ntchito toluene youma ngati zopangira, amawonjezera chothandizira, amalowetsa mpweya wa chlorine, amapanga chlorination reaction pansi pa chikhalidwe china cha kutentha kuti apeze mankhwala, ndiyeno amadutsa njira yolekanitsa kuti apeze p-chlorotoluene.Chopangidwa ndi njirayi ndi chisakanizo cha p-chlorotoluene ndi o-chlorotoluene.Pakupanga, pali kusiyana kwa chiŵerengero chotulutsa cha awiriwa pogwiritsa ntchito zopangira zosiyana.Njira yolekanitsa ikhoza kukhala njira yosinthira kristalo, njira yotsatsira ma molekyulu adsorption, etc.
p-Chlorotoluene zimagwiritsa ntchito mankhwala, mankhwala, utoto, solvents, organic synthesis ndi zina.Pazamankhwala, p-chlorotoluene ikhoza kugwiritsidwa ntchito kupanga mapiritsi a clomezadone, pyrimethamine, clotrimide, etc.;m'munda wa mankhwala ophera tizilombo, angagwiritsidwe ntchito kupanga mankhwala ophera tizilombo, herbicides, fungicides, etc. M'munda wa utoto, ukhoza kugwiritsidwa ntchito kupanga asidi buluu 90, CI kufalitsa buluu 109, etc.;m'munda wa kaphatikizidwe organic, angagwiritsidwe ntchito pokonzekera p-chlorobenzaldehyde, p-chlorobenzoic asidi, p-chlorobenzonitrile, p-chlorobenzoyl kolorayidi etc.;Angagwiritsidwenso ntchito ngati mphira, zosungunulira utomoni.
Malinga ndi "2021-2025 China's p-chlorotoluene industry development status and production and sales data analysis" lotulutsidwa ndi Xinsijie Industry Research Center, p-chlorotoluene ikhoza kukumana ndi zochitika zosiyanasiyana pokonzekera mankhwala osiyanasiyana abwino, ndi zotumphukira zake. ndiye mtundu wofunidwa kwambiri komanso wogwiritsidwa ntchito kwambiri pakati pa ma isomeri a chlorotoluene.Popindula ndi chitukuko chofulumira cha mafakitale akumunsi, dziko langa lakhala dziko lomwe limapanga p-chlorotoluene padziko lonse lapansi.Kuphatikiza pa kukwaniritsa zosowa za msika wapakhomo, zogulitsazo zimatumizidwanso kumisika yakunja.Akuti kuyambira 2020 mpaka 2025, msika wapadziko lonse wa p-chlorotoluene udzakula pafupifupi 4.0%, ndipo msika wakudziko langa wa p-chlorotoluene uli ndi chiyembekezo chabwino cha chitukuko.
Mabizinesi ambiri akudziko langa a p-chlorotoluene amapanga zinthu zotsika.Chifukwa chake, m'dziko langa la p-chlorotoluene kupanga, kuchuluka kwa kudzigwiritsa ntchito ndi mabizinesi ndikwambiri, ndipo gawo lazogulitsa kunja ndi laling'ono.
Malinga ndi akatswiri amakampani ochokera ku Xinsijie, p-chlorotoluene ndi chinthu chofunikira kwambiri chopangira mankhwala komanso mankhwala abwino apakatikati.Amagwiritsidwa ntchito kwambiri muzamankhwala, mankhwala ophera tizilombo, utoto ndi minda ina, ndipo kufunikira kwa msika kukukulirakulira.
