Mokhoa o matla oa ho hlaphoheloa le ho sebelisa hape dichloromethane lits'ebetsong tsa tlhahiso o fumane matla ka selemo sa 2023. E thehiloe ke mokhatlo oa Europe oa lipatlisiso, sistimi ena e koetsoeng e sebelisa mahlale a tsoetseng pele a adsorption ho hapa le ho hloekisa mouoane oa MC o hlahisitsoeng nakong ea tlhahiso ea ho roala. Liteko tsa pele li bonts'a sekhahla sa ho hlaphoheloa sa 92%, se fokotsa haholo tšebeliso ea thepa e tala le mesi.
Theknoloji e kopanya tlhahlobo e tsamaisoang ke AI ho ntlafatsa lipotoloho tsa tšebeliso ea solvent, ho netefatsa hore ho latela meeli e tiileng ea ho pepeseha mosebetsing. Liindasteri tse kang tlhahiso ea polycarbonate le ho hloekisa likarolo tsa elektroniki li ntse li leka sistimi ena, e tsamaellanang le lipehelo tsa moruo tse chitja tsa Lekhotla la Machabeng la Mekhatlo ea Lik'hemik'hale (ICCA) 2030.
2. Ho tiisa Melao ea Lefatše ka Phallo ea MC
Mekhatlo e laolang e ntse e tsoela pele ho lekola Methylene Chloride ka lebaka la bokhoni ba eona ba ho fokotseha ha ozone (ODP) le likotsi tsa bophelo bo botle mosebetsing. Ka Loetse 2023, European Chemicals Agency (ECHA) e ile ea etsa tlhahiso ea liphetoho ho melaoana ea REACH, e laelang hore ho lateloe tlhahiso ea nako ea 'nete bakeng sa lits'ebeletso tse sebelisang lithane tse fetang 50 tsa MC ka selemo. Melao e boetse e hloka litlhahlobo tse ling bakeng sa lits'ebetso tseo e seng tsa bohlokoa ka Q2 2024.
Ka nako e ts'oanang, Setsi sa Ts'ireletso ea Tikoloho sa US (EPA) se qalile tlhahlobo ea boemo ba MC tlasa Molao oa Taolo ea Lintho Tse Chefo (TSCA), ka liphuputso tsa pele tse fanang ka maikutlo a hore ho na le meeli e thata ea khatello ea moea sebakeng sa mosebetsi - e ka fokotsang moeli ho tloha ho 25 ppm ho isa ho 10 ppm. Mehato ena e ikemiselitse ho rarolla mathata a ntseng a eketseha ka lebaka la litlamorao tsa nako e telele tsa methapo ea kutlo har'a basebetsi ba indasteri.
3. Lekala la Meriana le Amohela Mekhoa e Meng ea Tala
Indasteri ea meriana, e leng moreki ea ka sehloohong oa Methylene Chloridefor crystallization ea lithethefatsi le ho ntšoa, e potlakisa liteko tsa li-solvents tse thehiloeng ho bio. Phuputso e hlahlobiloeng ke lithaka e phatlalalitsoeng ho *Green Chemistry* (Phato 2023) e totobalitse lihlapolli tse nkiloeng ho limonene e le li-AC tse ka nkeloang sebaka ka har'a motsoako oa API (motsoako o sebetsang oa meriana), tse fihlelang litholoana tse bapisoang ka 80% ea boemo bo tlase ba chefo.
Leha ho nkeloa ka lapeng ho ntse ho eketseha ka lebaka la liphephetso tsa botsitso ba moralo, likhothaletso tsa taolo tlas'a Molao oa Phokotso ea Litheko tsa US ke lichelete tsa lifeme tsa liteko tse ikemiselitseng ho eketsa mekhoa ena e meng. Bahlahlobisisi ba bolela esale pele phokotso ea 15–20% ea tlhoko ea MC ho tsoa ho pharma ka 2027 haeba mekhoa ea hajoale ea R&D e phehella.
4. Tsoelo-pele ho MC Risk Mitigation Technologies
Litaolo tse ncha tsa boenjiniere li fokotsa likotsi tse amanang le MC. Sehlopha sa lipatlisiso sa Amerika Leboea se sa tsoa senola mokhoa oa ho hloekisa o thehiloeng ho nanoparticle o senyang MC e setseng metsing a litšila hore e be lihlahisoa tse se nang chefo tse kang li-ion tsa chloride le carbon dioxide. Ts'ebetso ea photocatalytic, e sebelisoang ke lebone la UV le nang le matla a tlaase, e finyella katleho ea 99.6% ea ho senyeha 'me e ntse e kenngoa litsing tsa ho hloekisa metsi a litšila ka lik'hemik'hale.
Ho feta moo, lisebelisoa tsa ts'ireletso tsa botho tsa moloko o latelang (PPE) tse nang le li-respirators tse ntlafalitsoeng ke graphene li bonts'itse katleho ea 98% ho thibela mouoane oa MC nakong ea mesebetsi e pepeneneng joalo ka ho hlobola pente. Lintlafatso tsena li tsamaellana le litataiso tse ntlafalitsoeng tsa OSHA tse totobatsang taolo ea ho pepeseha ha maemo bakeng sa batsamaisi ba MC.
5. Liphetoho tsa Maraka tse tsamaisoang ke Moshoelella
Leha e le karolo ea eona e tiileng, Methylene Chloride e tobane le khatello e matla ho tsoa ho litekanyetso tsa matsete tsa ESG (tikoloho, sechaba, puso). Phuputso ea 2023 e entsoeng ke mohlahlobi ea ka sehloohong oa indasteri ea lik'hemik'hale e senotse hore 68% ea bahlahisi ba tlase hona joale ba etelletsa pele barekisi ka merero e netefalitsoeng ea ho fokotsa tlhahiso ea MC. Mokhoa ona o hlohlelletsa mahlale a mahlale a ho hlaphoheloa ha solvent le mekhoa ea tlhahiso ea bio-hybrid.
Haholo-holo, morero oa teko oa Asia Boroa-bochabela o atlehile ho kopanya MC ka ho sebelisa methane chlorination e tsamaisoang ke matla a tsosolositsoeng, ho khaola khabone ea tlhahiso ka 40%. Leha ho ntse ho le teng liqholotso tsa scalability, matsapa a joalo a toboketsa tjantjello ea lekala la lik'hemik'hale mabapi le lintho tse phelang ho tsona tse qhibilihisang khabone.
Qetello: Ho leka-lekanya Tšebeliso le Boikarabelo
Ha Methylene Chloride e ntse e le ea bohlokoa bakeng sa lits'ebetso tsa bohlokoa, tsepamiso ea indasteri mabapi le boqapi bo tsitsitseng le taolo ea taolo e ntse e eketseha.
