Methylene Chloride ningirakamaro cyane mu nganda, kandi iterambere ryinganda nubushakashatsi bwa siyanse ni byo byibandwaho cyane. Iyi ngingo izagaragaza iterambere ryayo iheruka kuva mu bintu bine: imiterere yisoko, imikorere igenga imikorere, ibiciro, hamwe nubushakashatsi bugezweho bwa siyansi.
Imiterere y'Isoko: Isoko ryisi ryibanze cyane, hamwe nabaproducer batatu ba mbere (nka Juhua Group, Lee & Man Chemical, na Jinling Group) bafite imigabane ihuriweho hafi 33%. Agace ka Aziya-Pasifika nisoko rinini, bingana na 75% byimigabane.
Ibikorwa bigenga:Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA) cyasohoye itegeko rya nyuma hashingiwe ku itegeko rigenga ibiyobyabwenge (TSCA) ribuza ikoreshwa rya methylene chloride mu bicuruzwa by’abaguzi nko gusiga amarangi no gushyiraho amategeko akomeye ku ikoreshwa ry’inganda.
Imigendekere y'Ibiciro: Muri Kanama 2025, kubera igipimo kinini cyo gukora mu nganda kiganisha ku isoko ryinshi, hamwe n’igihe kitari gito cyo gukenera hamwe n’ishyaka ridahagije ryo kugura hasi, ibiciro byaturutse ku nganda zimwe na zimwe byagabanutse munsi y’amafaranga 2000 / toni.
Imiterere y'Ubucuruzi:Kuva muri Mutarama kugeza Gicurasi 2025, Ubushinwa bwohereza mu mahanga methylene chloride bwiyongereye ku buryo bugaragara (umwaka-ku mwaka + 26.1%), cyane cyane bugenewe Aziya y'Amajyepfo y'Uburasirazuba, Ubuhinde, n'utundi turere, bifasha kugabanya umuvuduko w'itangwa ry'imbere mu gihugu.
Imipaka mubushakashatsi bugezweho
Mu rwego rwubushakashatsi bwa siyanse, ubushakashatsi kuri methylene chloride hamwe nibindi bifitanye isano bigenda bitera imbere bigana ku cyatsi kibisi kandi cyiza. Hano hari ibyerekezo byinshi byingenzi:
Uburyo bwa Green Synthesis:Itsinda ry’ubushakashatsi ryaturutse muri kaminuza y’ikoranabuhanga ya Shandong ryasohoye ubushakashatsi bushya muri Mata 2025, butanga igitekerezo gishya cya “redox itwarwa na magnetiki.” Iri koranabuhanga rikoresha umuzenguruko wa magneti uzunguruka kugirango ubyare ingufu zituruka ku mashanyarazi mu cyuma, bityo bigatwara imiti. Ubu bushakashatsi bwerekanye uburyo bwa mbere bwokoresha ingamba muburyo bwo gutambutsa ibyuma byinzibacyuho, bigerwaho neza no guhuza kwambukiranya imipaka ya aryl chloride idakora neza na chloride ya alkyl. Ibi bitanga inzira nshya yo gukora inert ya chimique (nka C-Cl bonds) mubihe byoroheje, hamwe nibishobora gukoreshwa mugari.
Gutandukanya uburyo bwo gutandukana:Mu musaruro wimiti, gutandukana no kwezwa nintambwe zingenzi zitwara ingufu. Ubushakashatsi bumwe bwibanze ku guteza imbere ibikoresho bishya byo gutandukanya imiti ivanze na methylene chloride synthesis. Ubu bushakashatsi bwakoze ubushakashatsi ku gukoresha methanol nk'iyikuramo kugira ngo itandukanye imvange ya dimethyl ether-methyl chloride ifite umuvuduko muke ugereranije, igamije kunoza imikorere yo gutandukana no kunoza ibipimo ngenderwaho.
Ubushakashatsi bwa Porogaramu muri Sisitemu nshya ya Solvent:Nubwo idafite uruhare runini rwa methylene chloride, ubushakashatsi ku mashanyarazi yimbitse ya eutectic (DES) yasohotse muri PMC muri Kanama 2025 ni ingenzi cyane. Ubu bushakashatsi bwatanze ubumenyi bwimbitse kumiterere yimikoranire ya molekile muri sisitemu yo gukemura. Iterambere muri ubwo buryo bwikoranabuhanga ryatsi rishobora, mugihe kirekire, gutanga uburyo bushya bwo gusimbuza ibinyabuzima bimwe na bimwe gakondo bihindagurika, harimo na methylene chloride.
Muri make, methylene chloride inganda muri iki gihe kiri mugihe cyinzibacyuho irangwa n'amahirwe n'ingorane.
Inzitizibigaragarira cyane cyane mu mabwiriza akomeye y’ibidukikije (cyane cyane ku masoko nk’Uburayi na Amerika) hamwe no kugabanuka kw’ibisabwa mu turere tumwe na tumwe dusaba (nk'ibisiga amarangi).
Amahirweicyakora, kuryama mubisabwa bikenerwa mumirenge aho abasimbuye neza bataraboneka (nka farumasi na synthesis ya chimique). Icyarimwe, gukomeza kunoza imikorere yumusaruro no kwagura amasoko yoherezwa mu mahanga nabyo bitanga imbaraga mu iterambere ry’inganda.
Iterambere ry'ejo hazaza riteganijwe gushingira cyane ku bikorwa-byo hejuru, bifite isuku-nziza cyane kandi udushya tw’ikoranabuhanga duhuza n'amahame ya chimie yicyatsi.
