Intshayelelo Eneenkcukacha
I-1,1-dimethylireayinxalenye yemichiza ngefomula yemolekyuli c3h8n2n2o. Ikwabizwa ngokuba yi-DIMETHYLUREA okanye DMU. Yinto yomgubo we-crystalline emhlophe, inyibilika ngokulula kumanzi kunye nezinyibilikisi eziphilayo.
I-1,1-dimethylurea ineenkqubo ezahlukeneyo kumashishini ahlukeneyo. Olunye losetyenziso lwayo oluphambili lufana ne-regent kwi-ornthesic synthesis. Ihlala isetyenziswa njengomthombo we-DIMETHyLAmine, ibhloko yesakhiwo esibalulekileyo kwimveliso yeendawo zamayeza, idayi kunye nezinye iichemicals.
Kumzi-mveliso wamachiza, i-1,1-dimethylurea isetyenziswa njengentshabalalo ye-synthesis yeziyobisi kunye neziyobisi eziphakathi.
Ingasetyenziswa njengearhente yokhuselo kumaqela asebenza ngobuchule kwimichiza ngexesha lokuphendula kwezinto. Ikwasetyenziswa njengeyona nto iphambili ekuphenduleni.
Ukongeza, i-1,1-dimethylirea ikwasetyenziswa kwi-synthesis ye-herbicides kunye ne-fungicides. Isebenza njengesiqhelo kwaye iphucule intsebenzo yezi Agrochemicals. Kubaluleke kakhulu ukuphatha i-1,1-dimethylirea ngononophelo kuba ithathwa njengeyingozi ukuba ingeniswe okanye inxibelelana nolusu okanye amehlo. Amanyathelo afanelekileyo okhuseleko kufuneka athathwe xa esebenza nale nto, enjengokunxiba izixhobo ezikhuselayo kunye nokuqinisekisa ukuba uvelwano oluhle.
Isishwankathelo, i-1,1-dimethylurea yindawo yeqela elininzi elinokusetyenziswa kwi-ornthesic synthesi, amayeza, kunye ne-agrochemicals. Iipropathi zayo zenza ukuba kube luncedo njenge-redant, ukukhusela, kunye nokuthatha inxaxheba kwiinkqubo ezahlukeneyo zekhemikhali.
Isicelo
I-1,1-dimethylire, ekwabizwa ngokuba yi-DMEU, inezicelo ezininzi ezibalulekileyo kumashishini ahlukeneyo. Nazi ezinye izinto ezibonakalayo:
Ishishini lamachiza:I-DMEU isetyenziswa njengendawo ephakathi kwi-synthesis ye-PHERMACEOCTS. Ingasebenza njengendawo yokuphinda isebenze kwimveliso yeziyobisi njenge-antipyrine, phenobarbital, ne-theophylline. Isakhiwo sika-Dmeu sikuvumela ukuba sisebenze njengebhlokhi yokwakha ukulungiselela ukwenziwa kweemolekyuli ezintsonkothileyo.
I-Ornthesic Synthesis:I-DMEU iqeshwe ngokubanzi kwi-synthesi ye-organic njenge-regent okanye isoyile. Ingathatha inxaxheba kwimisebenzi eyahlukeneyo yemichiza enjengokunyamezela, i-oxidation, kunye ne-alkyting. Ukusebenza kuka-DMEU kunye nozinzo kwenza ilungele uluhlu lwezinto zokwenza izinto eziphilayo ezifanelekileyo.
Umzi mveliso weDySesuff:I-DMEU isetyenziswa njengento esebenzayo yokufumana i-dyes i-DEES kunye ne-pigments. Isakhiwo sayo semichiza sikuvumela ukuba ithathe inxaxheba ekunikezelweni kwesiphumo sokusekwa kwemibala esebenzayo neqinileyo. I-Dye Molecules evelisiweyo isebenzisa i-DMEU isetyenziswe kwii-lespings, ii-interks zokushicilela, kunye nezinye izicelo zeDySesuff.
Ishishini lePolymer:I-DMEU ineenkqubo zokuveliswa kweepolimers kunye ne-resins. Ingasetyenziswa njenge-arhente yokudibanisa okanye njengecandelo kwi-synthesis ye-polynthene kunye ne-epoxy resins. Oku kufumanisa i-resins fumanisa ukusebenzisa iingubo, imihlambi, kunye namanye amashishini ahlukeneyo.
Imveliso ye-distilizer:I-DMEU inokusetyenziswa ekuqulunqweni kwezichumisi ezihamba kancinci. Iipropathi zayo ezilawulwayo zivumela ukukhululwa ngokuthe ngcembe i-nitrogen, enikezela ngezityalo ngokubonelela ngezondlo kwixesha elininzi.
Kubalulekile ukuba uqaphele ukuba xa usebenza ne-DMEU okanye nayiphi na into yekhemikhali, izikhokelo ezichanekileyo nezikhokelo ezifanelekileyo kufuneka zilandelwe ukuqinisekisa ukhuseleko lwabantu kunye nokusingqongileyo.
