Inoshandisa:1,1-dimethylurea (n-n-dimethylurea) yashandiswa muDowex-50w Ion exchange resin-inosimudzira-4-ARYL-3,4-dihydropyrimidinones.
Tsanangudzo yeruzivo
1,1-dimethylureaIyo yemakemikari yakaenzana neiyo molecular formula c3h8n2o. Izvo zvinozivikanwa seDimethylurea kana Dmu. Iyo chena crystalline poda, inochema nyore nyore mumvura uye organic sol sol.
1,1-dimethylurea ine dzakasiyana siyana maindasitiri akasiyana. Imwe yeinoshandiswa mainini ndeyekuwedzera mune organic synthesis. Zvinowanzoshandiswa seanobva dimethylamine, chivakwa chakakosha chivakwa mukugadzirwa kwemishonga yemishonga, dhayi nemamwe makemikari.
Muindasitiri yechechi, 1,1-dimethylurea inoshandiswa sepamberi pechirevo cheiyo synthesis yemishonga uye zvinodhaka.
Inogona kushandiswa seyemumiriri anodzivirira emakemikari anodzikisira emapoka emapoka panguva yekuita organic. Izvo zvinoshandiswawo sekatanga mune zvimwe zviitiko.
Mukuwedzera, 1,1-dimethylure zvakare inoshandiswawo mune synthesis yemakwenzi uye fungicides. Inoita sedhizimusi uye inowedzera kuita kweaya okungoma. Zvakakosha kwazvo kubata 1,1-dimethylurea nehanya nekuti inoonekwa ichikuvadza kana yakamiswa kana kusangana neganda kana maziso. Zvakakodzera zvekuchengetedza zvekuchengetedza zvinofanirwa kutorwa kana uchishanda neiyi nzvimbo, sekupfeka nhandare dzekudzivirira uye kuona kuti yakanaka yekuvhunduka.
Mukupfupikisa, 1,1-dimethylurea chikamu chaunga chinogona kuiswa mu organic syntic synthesis, mishonga yemishonga, uye agrochemicals. Zvivakwa zvayo zvinoita kuti zvive zvinobatsira seyedzinza, kuchengetedza, uye tika mune akasiyana emakemikari maitiro.
Application
1,1-dimethylurea, inozivikanwawo seDMU, ine zvingaitika zvinoverengeka mumasango akasiyana siyana. Heano mamwe anoshandiswa anoshandisa:
Indasitiri yeMishonga:DMEU anoshandiswa seyakajairwa yakanyorwa mune synthesis yemishonga yemishonga. Inogona kuita seinoita chiitiko mukugadzirwa kwezvinodhaka kunge Antipyrine, chifananidzo, uye theophylline. Chimiro chaDbu chakasarudzika chinozvitendera kuti vashande sechigadzirwa chekuvaka kuti vaumbe mamaleculx yakaoma mamalecules mamorekuru.
Ornisic Synthesis:DMEU anowanzoshanda zvakanyanya mu organic synthesis so organt kana solvent. Inogona kutora chikamu mumapakemikari akasiyana emakemikari akadai sekukona, oxidation, uye nyasha. Kugadzirisa kwaDbu uye kugadzikana kunoita kuti zviite kuti zviite kune huwandu hwekuita maitiro ekugadzira yakakosha organic compic makomputa.
Dyestuff Indasitiri:DMEU anoshandiswa seshanduro yepakati yekugadzira mamwe madhiri uye pigment. Kugadzirwa kwayo kwemakemikari kunobvumira kutora chikamu mukuita zvinoguma nekuumbwa kwemavara ane simba uye anobhadharwa. Dye maroyi akagadzirwa uchishandisa DMEU anogona kushandiswa muzvinyorwa, kudhinda inks, uye zvimwe zvikumbiro zveDyestuff.
Polymer Indasitiri:DMEU ine zvikumbiro mukugadzirwa kwePolymers uye anogara. Inogona kushandiswa seyakawirirana-inobatanidza mumiririri kana sechinhu chiri mu synnthesis yePolyurethane uye epoxy resins. Aya maini anowana anoshandiswa mumatombo, anomisheni, uye mamwe maindasitiri akasiyana.
Fetiraiza Indasitiri:DMEL inogona kushandiswa mukuumbwa kwekusunungurwa-kusunungura fetilizers. Zvivakwa zvaro zvinodzorwa zvinobvumidzwa kuburitswa zvishoma nezvishoma zve nitrogen, kupa zvidyarwa zvine nzvimbo yakatsiga yezvivakwa zvakaringana.
Izvo zvakakosha kuti uzive kuti kana uchishanda naDMU kana chero makemikari akaomesesa, kuchengetedza kwakakodzera uye nhungamiro dzinofanira kuteverwa kuti uve nechokwadi chekuchengeteka kwevanhu uye nharaunda.
