M-cresol, izwi kandi nka m-methylphenol cyangwa 3-methylphenol, ni ifumbire mvaruganda hamwe n’imiti ya C7H8O. Ku bushyuhe bwicyumba, mubusanzwe ni ibara ryumuhondo cyangwa ibara ryumuhondo ryoroshye, rishonga gato mumazi, ariko rigashonga mumashanyarazi nka Ethanol, ether, hydroxide ya sodium, kandi ifite umuriro. Uru ruganda rufite uburyo bwinshi bwo gukoresha murwego rwimiti myiza.

Umurima wica udukoko: Nkibikoresho bigereranijwe kandi bibisi byimiti yica udukoko, m-cresol irakoreshwa cyane mugukora imiti yica udukoko twangiza pyrethroide, nka fluazuron, cypermethrine, glyphosate, na dichlorophenol, itanga imiti yica udukoko m-phenoxybenzaldehyde. Mu rwego rwa farumasi, m-cresol ifite uburyo bwinshi bwo kuyikoresha kandi irashobora gukoreshwa nkibikoresho fatizo mu gukora imiti itandukanye, nk'imiti igabanya ubukana, imiti igabanya ubukana, n'ibindi. Inganda nziza yimiti: m-cresol irashobora gukoreshwa mugukora ibicuruzwa bitandukanye byimiti. Kurugero, irashobora kwitwara hamwe na fordehide kugirango ikore m-cresol formaldehyde resin, ikaba ari imiti yica udukoko twica udukoko kandi irashobora gukoreshwa mugukora fungiside nudukoko. Byongeye kandi, irashobora kandi gukoreshwa mugukora antioxydants, amarangi, ibirungo, nibindi. Indi mirima: m-cresol irashobora kandi gukoreshwa mugutegura ibikoresho bikora, nkibikoresho byo guhanahana ion, adsorbents, nibindi.

1 、 Incamake yuburyo bwo kubyaza umusaruro itandukaniro ryimbere mu gihugu ndetse n’amahanga

Igikorwa cyo gukora meta cresol gishobora kugabanywa mubyiciro bibiri: uburyo bwo kuvoma nuburyo bwo guhuza. Uburyo bwo kuvoma burimo kugarura cresol ivanze mumashanyarazi yamakara hanyuma ukabona meta cresol binyuze muburyo butandukanye bwo gutandukana. Amategeko ya synthesis akubiyemo uburyo butandukanye nka toluene chlorination hydrolysis, uburyo bwa isopropyltoluene, nuburyo bwa m-toluidine diazotisation. Intandaro yubu buryo ni uguhuza cresol binyuze mumiti ya chimique hanyuma ukayitandukanya kugirango ubone m-cresol.

Kugeza ubu, haracyari icyuho kinini mubikorwa byo gukora cresol hagati y'Ubushinwa n'ibihugu by'amahanga. Nubwo hari intambwe imaze guterwa mubikorwa byo gukora m-cresol mu Bushinwa mu myaka yashize, haracyari ibitagenda neza mu kugenzura imiterere y’imiti, guhitamo catalizaires, no gucunga inzira. Ibi biganisha ku giciro kinini cya meta cresol imbere mu gihugu, kandi ubuziranenge buragoye guhangana nibicuruzwa byatumijwe hanze.

2 、 Inzitizi niterambere mugutandukanya ikoranabuhanga

Ikoranabuhanga ryo gutandukana ningirakamaro mubikorwa byo gukora meta cresol. Bitewe no gutandukanya ingingo ya 0.4 only gusa no gutandukanya ingingo ya 24,6 ℃ hagati ya meta cresol na para cresol, biragoye kubitandukanya neza ukoresheje uburyo bwa distillation hamwe nuburyo bwo korohereza. Kubwibyo, inganda muri rusange zikoresha molekulari ya elegitoronike hamwe nuburyo bwa alkylation bwo gutandukana.

Muburyo bwa molekile ya elegitoronike ya adsorption, guhitamo no gutegura amashanyarazi ya molekile ni ngombwa. Amashanyarazi meza yo mu rwego rwo hejuru arashobora kwamamaza neza meta cresol, bityo akagera ku gutandukana neza na para cresol. Hagati aho, iterambere ryibintu bishya kandi bikora neza nicyerekezo cyingenzi cyiterambere muburyo bwo gutandukanya ikoranabuhanga. Izi catalizike zirashobora kunoza imikorere yo gutandukana, kugabanya gukoresha ingufu, no kurushaho guteza imbere uburyo bwo gukora meta cresol.

3 pattern Isoko ryisi yose nu Bushinwa uburyo bwa cresol

Igipimo cy’umusaruro wa meta cresol ku isi kirenga toni 60000 / mwaka, muri zo Langsheng ukomoka mu Budage na Sasso ukomoka muri Amerika n’abakora cyane meta cresol ku isi, aho ubushobozi bwo gukora bwaba bugera kuri toni 20000 / ku mwaka. Izi sosiyete zombi ziri mu myanya ya mbere mu nganda mu bijyanye n’umusaruro wa meta cresol, kugenzura ubuziranenge, no guteza imbere isoko.

Ibinyuranye, umubare w’inganda zitanga umusaruro wa cresol mu Bushinwa ni muto, kandi umusaruro rusange ni muto. Kugeza ubu, inganda zikomeye zo mu bwoko bwa cresol mu Bushinwa zirimo ikoranabuhanga rya Haihua, Dongying Haiyuan, na Anhui Shilian, ubushobozi bwabo bwo kubyaza umusaruro bugera kuri 20% by’ubushobozi bwa cresol ku isi. Muri byo, Haihua Technology niyo ikora meta cresol nini mu Bushinwa, ifite umusaruro wa toni hafi 8000. Nyamara, umusaruro nyawo uhindagurika bitewe nimpamvu zitandukanye nko gutanga ibikoresho fatizo nibisabwa ku isoko.

4 、 Gutanga no gusaba ibintu hamwe no gutumizwa mu mahanga

Isoko n'ibisabwa ku isoko rya cresol mu Bushinwa byerekana ihindagurika runaka. Nubwo umusaruro w’imbere mu gihugu wa cresol wakomeje kwiyongera mu myaka yashize, haracyari icyuho kinini cyo gutanga bitewe n’imikorere y’ibicuruzwa ndetse no kuzamuka kw'isoko ryo hasi. Kubera iyo mpamvu, Ubushinwa buracyakeneye gutumiza meta cresol nyinshi buri mwaka kugirango huzuzwe ibitagenda neza ku isoko ryimbere mu gihugu.

Nk’uko imibare ibigaragaza, umusaruro wa cresol mu Bushinwa mu 2023 wari hafi toni 7500, mu gihe ibicuruzwa byatumijwe mu mahanga byageze kuri toni 225. Cyane cyane mu 2022, kubera ihindagurika ry’ibiciro by’isoko mpuzamahanga no kuzamuka kw’imbere mu gihugu, ibicuruzwa biva mu mahanga biva mu Bushinwa byarengeje toni 2000. Ibi byerekana ko isoko rya cresol mubushinwa rishingiye cyane kubitumizwa hanze.

5 trends Ibiciro byisoko ryisoko nibintu bigira ingaruka

Igiciro cyisoko rya meta cresol giterwa nimpamvu zitandukanye, zirimo ibiciro byamasoko mpuzamahanga, isoko ryimbere mu gihugu hamwe nibisabwa, ibiciro byumusaruro, na politiki yubucuruzi mpuzamahanga. Mu myaka mike ishize, igiciro rusange cyisoko rya meta cresol cyerekanye ihindagurika ryizamuka. Igiciro cyo hejuru cyigeze kugera kuri 27500 yu / toni, mugihe igiciro cyo hasi cyamanutse kigera kuri 16400.

Igiciro cyisoko mpuzamahanga gifite ingaruka zikomeye kubiciro byimbere muri cresol. Kubera icyuho gikomeye cyo gutanga ku isoko rya cresol hagati yUbushinwa, ibiciro bitumizwa mu mahanga akenshi biba ibintu byerekana ibiciro byimbere mu gihugu. Ariko, hamwe no kuzamuka kwumusaruro wimbere mu gihugu no kuzamura urwego rwinganda, ubwiganze bwibiciro byimbere mu gihugu buragenda bugaruka buhoro buhoro. Hagati aho, kunoza imikorere y’imbere mu gihugu no kugenzura ibiciro nabyo bigira ingaruka nziza ku biciro by’isoko.

Byongeye kandi, ishyirwa mu bikorwa rya politiki yo kurwanya ibicuruzwa nabyo bigira ingaruka runaka ku giciro cy’isoko rya meta cresol. Kurugero, Ubushinwa bwatangiye iperereza rirwanya guta ibicuruzwa kuri meta cresol yatumijwe mu mahanga ikomoka muri Amerika, Umuryango w’ubumwe bw’ibihugu by’Uburayi, n’Ubuyapani, bigatuma bigora ibicuruzwa bya meta cresol biva muri ibi bihugu kwinjira ku isoko ry’Ubushinwa, bityo bikagira ingaruka ku itangwa ry’ibisabwa hamwe n’ibiciro by’isoko rya meta cresol ku isi.

6 、 Hasi yisoko ryisoko ryisoko hamwe nubushobozi bwo gukura

Nkurwego rwingenzi hagati yinganda zikora imiti, meta cresol ifite intera nini yimikorere ikoreshwa. Mu myaka yashize, hamwe n’iterambere ryihuse ry’isoko rya menthol hamwe n’udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko twangiza udukoko.

Menthol, nkibigize ibirungo byingenzi, ifite uburyo bwinshi bwo gukoresha mubikorwa bya chimique ya buri munsi. Hamwe n’abantu bakurikirana ubuzima bwiza no gukomeza kwaguka ku isoko ry’ibicuruzwa bya buri munsi, icyifuzo cya menthol nacyo kiriyongera. Nka kimwe mu bikoresho byingenzi bibyara umusaruro wa menthol, isoko rya m-cresol naryo ryiyongereye.

Mubyongeyeho, inganda zica udukoko nimwe mubice byingenzi bikoreshwa muri meta cresol. Hamwe no kurushaho kumenyekanisha ibidukikije no gukosora no kuzamura inganda zica udukoko, icyifuzo cy’ubumara bwica udukoko twangiza, cyangiza ibidukikije, kikaba cyiyongera. Nkibikoresho byingenzi byokoresha imiti yica udukoko twinshi, isoko rya meta cresol rizakomeza kwiyongera.

Usibye inganda za menthol na pesticide, m-cresol ifite kandi porogaramu nyinshi muri VE no mubindi bice. Iterambere ryihuse ryiyi mirima ritanga kandi amahirwe menshi yo gukura kumasoko ya meta cresol.

7 out Ibitekerezo by'ejo hazaza n'ibitekerezo

Urebye imbere, isoko rya cresol yo mu Bushinwa rihura n'amahirwe menshi n'ibibazo. Hamwe nogukomeza kunoza imikorere yumusaruro wimbere mu gihugu no gukomeza kwaguka kumasoko yo hepfo, ubushobozi bwo kuzamuka kwinganda za meta cresol buragenda bugaragara. Nubwo ihura n’ibibazo, inganda za cresol mu Bushinwa nazo zifite iterambere ryagutse. Mu kongera udushya mu ikoranabuhanga, kwagura amasoko mpuzamahanga, gushimangira ubufatanye n’inganda zo hasi, no kubona inkunga ya guverinoma, biteganijwe ko inganda za cresol z’Ubushinwa zizagera ku majyambere arambye kandi arambye mu bihe biri imbere.
