M-cresol, omwe amadziwikanso kuti m-methylphenol kapena 3-methylphenol, ndi gawo lolinganiza ndi njira ya mankhwala C7h8o. Kutentha, nthawi zambiri kumakhala madzi opanda utoto kapena kuwala kwa madzi, koma sungunuka m'madzi monga Ethanol, ethethel hydroxide, ndipo ali ndi chinyengo. Dongosolo ili limakhala ndi ntchito zingapo m'munda wa mankhwala abwino.

Trastic Field: Monga chuma chapakatikati komanso chosaphika cha mankhwala ophera tizilombo, m-z-vasosul chimagwiritsidwa ntchito popanga mankhwala osokoneza bongo, yperloosate, ndi dichlorophanol, phelloosate, ndi disnooxybedeldelwelwehyde. M'munda wa mankhwala, M-Cresol ali ndi mapulogalamu osiyanasiyana ndipo angagwiritsidwe ntchito ngati zida zopangira kupanga mankhwala osiyanasiyana, mankhwala osokoneza bongo, ndi zina zowonjezera, Konzani zida zamankhwala ndi mankhwala ophera tizilombo. Makampani Abwino Mankhwala: M-Cresol akhoza kugwiritsidwa ntchito kupanga zinthu zabwino zingapo zamankhwala. Mwachitsanzo, imatha kuchitirana ndi formaldehyde kupanga M-Cresol formaldehyde, yomwe ndi mankhwala ofunikira penti othira mkati ndipo imatha kugwiritsidwa ntchito kuti apakati patali ndi kutulutsa fungicides ndi mankhwala ophera tizilombo. Kuphatikiza apo, imatha kugwiritsidwanso ntchito kupaka antioxidants, utoto, zonunkhira, zina: M-Scepol amathanso kugwiritsidwa ntchito kukonza zida zogwirira ntchito, monga ion zosinthana ndi ion, etcorbents, etc.

1, mwachidule kwa ndondomeko yopanga ndi kusamvana kwapadziko lonse

Kupanga kwa meta cresol kumatha kugawidwa m'magulu awiri: njira yodukitsira ndi njira yophatikizira. Njira yotsitsira yowonjezera imaphatikizapo kutseka cresol yosakanizidwa kuchokera ku phula la malawi ndikupanga meta cresol kudzera pakulekanitsa. Malamulo a kapangidwe kake amaphimba njira zosiyanasiyana monga tuliene chlorination hydrolysis, isoproropytoltuene njira, ndi m-toluidine njira. Pakati pa njirazi ndikuphatikizira cresol yophatikizika kudzera m'machitidwe a mankhwala ndikuwasiyanitsa kuti apeze M-Cresol.

Pakadali pano, pali kusiyana kwakukulu pakupanga cresol pakati pa China komanso mayiko akunja. Ngakhale kupita patsogolo kwinaku kwachitika popanga m-cresol ku China zaka zaposachedwa, pakusankhidwa kwamitundu yambiri, ndikusankhidwa. Izi zimabweretsa mtengo wokwera kwambiri wa mankhwala a Meta Cresol, ndipo mtunduwo ndiwovuta kupikisana ndi zinthu zochokera kunja.

2, Zovuta ndi Kupanga Zinthu Zopatukana

Tekinoloji yolekanitsa ndiyofunikira pakupanga meta cresol. Chifukwa cha kuwira kosiyanasiyana kwa 0,4 ℃ ndikusungunuka kosiyanasiyana kwa Meta Cresol ndi paral cresol, ndikovuta kuti mudzilekanitse ndi njira za crystallization. Chifukwa chake, makampani nthawi zambiri amagwiritsa ntchito ma molecular shuepption ndi ma alkylation njira zolekanitsa.

Mu mankhwala a molecular njira ya Adsororption, kusankha ndi kukonzekera kwa makelecular sikofunikira. Zopusa zapamwamba kwambiri zimatha kuveka adsorb meta cresol, potero popewa kupatukana kogwira mtima kuchokera kwa paras cresol. Pakadali pano, chitukuko chatsopano komanso chokwanira komanso chothandizanso ndikuwongolera kofunikira pakupanga ukadaulo wolekanitsa. Mapangano amenewa amatha kukhala osintha mphamvu, kuchepetsa mphamvu zakutha kwa meta Cresol.

3, msika wapadziko lonse komanso wachikuda wa ku Cresol

Gawo lopanga padziko lonse lapansi la meta cresol limaposa 60000 matani atatu, lomwe Langsheng kuchokera ku Germany ndi Sasso kuchokera ku United States ndi opanga matope ambiri padziko lonse lapansi. Makampani awiriwa ali pamalo otsogola pamakampaniwo pankhani ya Meta Cresol, ulamuliro wapamwamba, ndi chitukuko cha msika.

Mosiyana ndi izi, kuchuluka kwa mabizinesi opanga a Cresol ku China ndi yaying'ono, komanso kuchuluka kwathunthu. Pakadali pano mabizinesi opanga aku China ku China amaphatikizapo ukadaulo wa Haisol, Dongnsing Haiyuan, ndi Ahui Shilian, omwe ali ndi maanja omwe ali ndi nkhani pafupifupi 20% ya zopanga zopangidwa padziko lonse lapansi. Pakati pawo, ukadaulo wa Haia ndi wobadwa kwambiri wa Meta Cresol ku China, ndi mwayi wapachaka wa matani 8000. Komabe, njira yeniyeni yosinthira mawu chifukwa cha zinthu zosiyanasiyana monga zopangira zinthu zopangira ndi zofuna pamsika.

4, perekani ndikufunsa kuti zinthu ndi kusiyanasiyana

Kuperekera ndikufuna kuti msika wa ziweto ku China ku China ukuonetsa kusazikira kwina. Ngakhale kupanga nyumba kwa Cresol kwakhala kukulira kwakukulu m'zaka zaposachedwa, padakali gawo lalikulu kwambiri chifukwa cha zovuta zomwe zingachitike ndi malo otsika. Chifukwa chake, China likufunikabe kutumiza kuchuluka kwa meta cresol chaka chilichonse kupanga zolakwazo pamsika wapabanja.

Malinga ndi ziwerengero, kupanga kwa cresol ku China mu 2023 kunali matani 7500, pomwe vocyuloyi idafika pafupifupi matani 225. Makamaka mu 2022, chifukwa chasinthasintha pamitengo yamasika ndi kukula kwa nyumba zamayiko akufunika, kuchuluka kwa cresol kuchokera ku China kupitirira matani 2000. Izi zikuwonetsa kuti msika wa celsool ku China umadalirabe zothandizira kunja.

5, mtengo wamsika ndi zinthu zokopa zinthu

Mtengo wamsika wa meta cresol umatengera zinthu zosiyanasiyana, kuphatikizapo mitengo yamayiko apadziko lonse lapansi, kupezeka kwa nyumba ndi zopangira, njira zopangira, ndi mfundo zapadziko lonse lapansi. M'zaka zingapo zapitazi, msika wa msika wonse wa meta Cresol wawonetsa kusintha kwakukulu. Mtengo wapamwamba kwambiri womwe umafika pa 27500 Yuan / Toni, pomwe mtengo wotsika kwambiri udatsikira mpaka 16400 Yuan / Toni.

Mtengo wamsika wapadziko lonse umakhudza kwambiri mtengo wapabanja wa resolol. Chifukwa cha kusiyana kwakukulu pamsika wa Cresol pakati pa China, mitengo yambiri nthawi zambiri imakhala chinthu chomwe chimapangitsa kuti pakhale mitengo yanyumba. Komabe, ndikukula kwa nyumba ndi kukonzanso kwa unyolo wamafakitale, kuchepa kwa mitengo yanyumba kukubwerera pang'onopang'ono. Pakadali pano, kusintha kwa njira zopangira nyumba ndi chiwongola dzanja kumakhalanso ndi zotsatira zabwino pamitengo yamasika.

Kuphatikiza apo, kukhazikitsa ndondomeko zotsutsana ndi kutayanso kumakhudzanso pamsika wamsika wa meta cresol. Mwachitsanzo, China yayamba kufufuza zofufuza zotsutsa pa ku United States kuchokera ku United States, European Union Ion Ionclections kuchokera kumayiko a Meta Cresol kuchokera ku mayiko awa kuti alowe ndi zomwe zimachitika pamsika wapadziko lonse wa metasna.

6, oyendetsa madalaivala ndi oyendetsa bwino

Monga wapakatikati mu makampani abwino azachipatala, meta cresol ali ndi mapulogalamu osiyanasiyana. M'zaka zaposachedwa, ndikukula msanga kwa misika yam'madzi ndi mankhwala ophera tizilombo, kufunikira kwa msika meta cresol kwawonetsa kukula.

Menthol, monga zonunkhira zoyenera, zimakhala ndi ntchito zingapo pamakampani tsiku ndi tsiku. Ndi kufunafuna anthu kwa moyo ndi kufalikira kosalekeza kwa msika wa mankhwala a tsiku ndi tsiku, kufunafuna kwa Methol kukuchulukirachulukira. Monga chimodzi mwazinthu zofunikira zopangira menthol, kufunikira kwa msika kwa M-Cresol wachulukanso.

Kuphatikiza apo, makampani omwe amapezekanso ndi mankhwala nawonso ndi amodzi mwa magawo ofunikira a meta cresol. Ndi kusintha kwa chilengedwe komanso kukonza ndikukweza mafakitale othilira, kufunikira kwa poizoni, komanso zinthu zachilengedwe zachilengedwe kumakuchulukirachulukira. Monga chinthu chofunikira chopangira mankhwala osiyanasiyana ophera tizilombo, kufunikira kwa msika Meta Cresol kumapitilirabe.

Kuphatikiza pa makonda ndi mafakitale othandizira, m-cresol amakhalanso ndi ntchito zambiri ku ve ndi minda ina. Kukula mwachangu kwa minda iyi kumapereka mwayi waukulu wogulitsa msika wa Meta Cresol.

7, malingaliro ndi malingaliro ndi malingaliro

Kuyang'ana M'tsogolo, msika waku China wa China ukukumana ndi mwayi ndi zovuta zambiri. Ndi kukhathamiritsa kwakanthawi kwa njira zopangira nyumba komanso kufalikira kosalekeza kwa misika yotsika, kukula kwa malonda a meta a Meta a Cresol kukuchulukirachulukira. Ndikukumana ndi mavuto, makampani ogulitsa a cresol ku China alinso ndi chiyembekezo chochuluka. Mwakukulitsa misika yamayiko, kulimbikitsa mgwirizano ndi mabizinesi otsika, ndipo kupeza chithandizo chamaboma, malonda a China a Cresol akuyembekezeka kukwaniritsa bwino mtsogolo.
