Ndixhamla kuphuhliso olukhawulezayo lwamashishini asezantsi, ilizwe lam liye laba lelona lizwe livelisa ip-chlorotoluene.Ukongeza kokuhlangabezana neemfuno zemarike yasekhaya, iimveliso zikwathunyelwa kumazwe angaphandle kwiimarike zaphesheya.
I-p-Chlorotoluene, eyaziwa ngokuba yi-4-chlorotoluene, ine-molecular formula C7H7Cl.Ukubonakala kwe-p-chlorotoluene ayinambala kunye nolwelo olucacileyo, kunye nephunga elikhethekileyo, ubuthi kunye nokucaphuka.I-p-Chlorotoluene ayinyibiliki emanzini, iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-alcohol, i-ether, ibenzene, i-acetone, i-chloroform, njl. njl. izitya.I-Para-chlorotoluene lolona hlobo lwemveliso ibalulekileyo phakathi kwe-isomer ezintathu zeklorotoluene.
Iindlela zokulungiselela ze-p-chlorotoluene ikakhulu zibandakanya indlela ye-toluene emnandi yeringi ye-chlorination, indlela ye-p-toluidine diazotization njalo njalo.Phakathi kwazo, indlela ye-toluene yeringi ye-chlorination yinkqubo yokulungiselela.Isebenzisa i-toluene eyomileyo njengento eluhlaza, yongeza i-catalyst, ingenisa igesi ye-chlorine, yenza i-chlorination reaction phantsi kwemeko ethile yokushisa ukufumana imveliso, kwaye emva koko iqhube inkqubo yokwahlula ukufumana i-p-chlorotoluene.Imveliso yale ndlela ngumxube we-p-chlorotoluene kunye ne-o-chlorotoluene.Kwinkqubo yokuvelisa, kukho ukungafani kumlinganiselo wokuphuma kwezi zibini usebenzisa i-catalysts ezahlukeneyo.Indlela yokwahlula ingaba yindlela yokulungisa icrystallization, indlela ye-molecular sieve adsorption, njl.
I-p-Chlorotoluene isetyenziswa kakhulu kumayeza, izibulali zinambuzane, idayi, izinyibilikisi, i-organic synthesis kunye nezinye iindawo.Kwintsimi yeyeza, i-p-chlorotoluene ingasetyenziselwa ukuvelisa iipilisi ze-clomezadone, i-pyrimethamine, i-clotrimide, njl.;kwintsimi ye-pesticides, ingasetyenziselwa ukuvelisa i-insecticides, i-herbicides, i-fungicides, njl njl. Kwintsimi yedayi, ingasetyenziselwa ukuvelisa i-acid blue 90, i-CI isasaze i-blue 109, njl.;kwintsimi ye-organic synthesis, ingasetyenziselwa ukulungisa i-p-chlorobenzaldehyde, i-p-chlorobenzoic acid, i-p-chlorobenzonitrile, i-p-chlorobenzoyl chloride njl.inokusetyenziswa njengerabha, isinyibilikisi sentlaka.
Ngokwe "2021-2025 iChina ye-p-chlorotoluene yophuhliso lwentengiso yeshishini kunye nemveliso kunye nengxelo yohlalutyo lwedatha" ekhutshwe yiXinsijie Industry Research Centre, i-p-chlorotoluene inokusabela ngeendlela ezahlukeneyo ukulungiselela iintlobo ngeentlobo zeemveliso zekhemikhali ezilungileyo, kunye nezinto eziphuma kuyo. lolona hlobo lufunwayo nolona lusetyenziswa kakhulu phakathi kwee-isomer ze-chlorotoluene.Ndixhamla kuphuhliso olukhawulezayo lwamashishini asezantsi, ilizwe lam liye laba lelona lizwe livelisa ip-chlorotoluene.Ukongeza kokuhlangabezana neemfuno zemarike yasekhaya, iimveliso zikwathunyelwa kumazwe angaphandle kwiimarike zaphesheya.Kuqikelelwa ukuba ukusuka ngo-2020 ukuya ku-2025, imakethi ye-p-chlorotoluene yehlabathi iya kukhula ngesantya sokukhula malunga ne-4.0%, kwaye ishishini lelizwe lam le-p-chlorotoluene linethemba lophuhliso oluhle.
Uninzi lwamashishini e-p-chlorotoluene kwilizwe lam avelisa iimveliso ezisezantsi.Ngoko ke, kwimveliso ye-p-chlorotoluene yelizwe lam, umlinganiselo wokuzisebenzisa ngamashishini aphezulu, kwaye umlinganiselo wokuthengiswa kwamanye amazwe uncinci.
Ngokwabahlalutyi boshishino abavela eXinsijie, ip-chlorotoluene yimathiriyeli ekrwada yekhemikhali ecolekileyo kunye nekhemikhali elungileyo ephakathi.Isetyenziswa kakhulu kumayeza, amayeza okubulala izinambuzane, idayi nakwamanye amasimi, kwaye imfuno yentengiso iyaqhubeka nokukhula.
