I-Methylene Chloride sisinyibilikisi esibalulekileyo semizi-mveliso, kwaye uphuhliso lwayo lwemizi-mveliso kunye nophando lwesayensi zizinto ekufuneka ziqwalaselwe kakhulu. Eli nqaku liza kuchaza uphuhliso lwayo lwamva nje kwiinkalo ezine: ulwakhiwo lwemarike, amandla olawulo, iindlela zamaxabiso, kunye nenkqubela phambili yophando lwesayensi lwamva nje.
Ulwakhiwo lweMarike: Imakethi yehlabathi igxile kakhulu, apho abavelisi abathathu abaphambili (abafana neJuhua Group, iLee & Man Chemical, kunye neJinling Group) babambe isabelo semakethi esidibeneyo esimalunga nama-33%. Ummandla weAsia-Pacific yeyona marike inkulu, ebalelwa malunga nama-75% esabelo.
Iinguqu zoLawulo:I-Arhente yoKhuseleko lweNdalo yase-US (i-EPA) ikhuphe umthetho wokugqibela phantsi koMthetho woLawulo lweZinto ezinobungozi (i-TSCA) othintela ukusetyenziswa kwe-methylene chloride kwiimveliso zabathengi ezifana nezihluzi zepeyinti kunye nokubeka imiqathango engqongqo ekusetyenzisweni kwemizi-mveliso.
Iindlela zokuThenga: Ngo-Agasti 2025, ngenxa yamanani aphezulu okusebenza kushishino akhokelela ekufumanekeni okuninzi, kunye nokufunwa kakhulu ngexesha lokuphumla kunye nomdla wokuthenga ongonelanga emva koko, amaxabiso avela kwabanye abavelisi ehle ngaphantsi kophawu lwe-2000 RMB/ton.
Imeko yoRhwebo:Ukususela ngoJanuwari ukuya kuMeyi 2025, ukuthunyelwa kwe-methylene chloride eTshayina kunyuke kakhulu (unyaka nonyaka +26.1%), ikakhulu kujoliswe eMzantsi-mpuma Asia, eIndiya, nakwezinye iindawo, nto leyo enceda ekunciphiseni uxinzelelo lokubonelela ngemveliso yasekhaya.
Imida kuPhando lweTekhnoloji yamva nje
Kwicandelo lophando lwesayensi, izifundo kwi-methylene chloride kunye neekhompawundi ezinxulumene noko ziqhubela phambili zisiya kwicala eliluhlaza nelisebenza ngakumbi. Nazi iindlela ezininzi ezibalulekileyo:
Iindlela zokwenziwa koLuhlaza:Iqela lophando elivela kwiYunivesithi yeTekhnoloji yaseShandong lipapashe uphando olutsha ngo-Epreli 2025, licebisa ingcamango entsha "ye-redox eqhutywa ngumbane." Le teknoloji isebenzisa intsimi yemagnethi ejikelezayo ukuvelisa amandla e-electromotive abangelwayo kumqhubi wesinyithi, ngaloo ndlela iqhuba iimpembelelo zeekhemikhali. Olu phononongo luphawule ukusetyenziswa kokuqala kwesi sicwangciso kwi-transition metal catalysis, ngempumelelo ifezekisa ukudityaniswa okuncitshiswayo kwee-aryl chloride ezingasebenziyo kakhulu kunye nee-alkyl chloride. Oku kubonelela ngendlela entsha yokusebenzisa iibhondi zeekhemikhali ezingasebenzisi khemikhali (ezifana neebhondi ze-C-Cl) phantsi kweemeko ezibuthathaka, ezinokusetyenziswa ngokubanzi.
Ukuphuculwa kweNkqubo yoKwahlula:Kwimveliso yeekhemikhali, ukwahlulahlula kunye nokucoca ngamanyathelo abalulekileyo asebenzisa amandla. Olunye uphando lugxile ekuphuhliseni isixhobo esitsha sokwahlula imixube yokusabela kwi-methylene chloride synthesis. Olu phando luhlolisise ukusebenzisa i-methanol njengento yokukhupha ngokwayo ukwahlula imixube ye-dimethyl ether-methyl chloride ene-volatility ephantsi, ijolise ekuphuculeni ukusebenza kakuhle kokwahlulahlula kunye nokwenza ngcono iiparameter zenkqubo.
Ukuphononongwa kwezicelo kwiiNkqubo eziNtsha zeSolvent:Nangona ingabandakanyi ngqo i-methylene chloride, uphando malunga ne-deep eutectic solvents (DES) olupapashwe kwi-PMC ngo-Agasti 2025 lubaluleke kakhulu. Olu phononongo lubonelele ngolwazi olunzulu malunga nohlobo lokunxibelelana kweemolekyuli kwiinkqubo ze-solvent. Inkqubela phambili kwezo teknoloji ze-solvent eziluhlaza, ekuhambeni kwexesha, inokubonelela ngamathuba amatsha okutshintsha ezinye ze-volatible organic solvents zemveli, kuquka i-methylene chloride.
Ngamafutshane, ishishini le-methylene chloride okwangoku likwixesha lotshintsho elibonakala ngamathuba kunye nemingeni.
Imingenizibonakala kakhulu kwimithetho yokusingqongileyo engqongqo ngakumbi (ingakumbi kwiimarike ezifana neYurophu ne-US) kunye nokuncipha kwemfuno okulandelayo kwezinye iindawo zesiqhelo zokusetyenziswa (ezifana nezihluzi zepeyinti).
AmathubaNangona kunjalo, kukho imfuno eqhubekayo kumacandelo apho izinto ezigqibeleleyo ezingasetyenziswayo (ezifana namayeza kunye nokuhlanganiswa kweekhemikhali). Kwangaxeshanye, ukuphuculwa okuqhubekayo kweenkqubo zemveliso kunye nokwandiswa kweemarike zokuthumela kwamanye amazwe nazo zibonelela ngamandla ophuhliso lweli shishini.
Uphuhliso lwexesha elizayo kulindeleke ukuba luthambekele ngakumbi kwiimveliso ezikhethekileyo ezisebenza kakuhle nezicocekileyo kakhulu kunye nophuhliso lwetekhnoloji oluhambelana nemigaqo yekhemistri eluhlaza.
