Iimpawu zekhemikhali:

Imveliso ecocekileyo ye-N-methylformamide lulwelo olungenambala, olucacileyo nolunobukrakra, mp-3.8℃, bp198℃, n25D1.43Chemicalbook10, uxinano oluhambelanayo 0.9986 (25℃), olunyibilikayo emanzini, kwaye lunokunyibilikisa iityuwa ezingaphiliyo. IneHygroscopic, ibola lula kwizisombululo zeasidi okanye zealkaline.

Ukusetyenziswa:

I-N-methylformamide sisixhobo esibalulekileyo sokwenziwa kwezinto eziphilayo. Isetyenziswa ekuhlanganiseni izibulali-zinambuzane, izibulali-zinambuzane kunye ne-acaricides i-monoformamidine kunye ne-diformamidine. Ikwasetyenziswa ekuveliseni amayeza, isikhumba sokwenziwa, isikhumba sokwenziwa kunye nesinyibilikisi seempahla zefayibha zamakhemikhali.

indlela yemveliso

Indlela ye-methylamine ifumaneka kwintsebenziswano phakathi kwe-methylamine kunye ne-carbon monoxide. I-CO+CH3NH2→HCONHCH3 Inika i-87.05kg/h, ngelixa inika i-56.5kg/h ye-carbon monoxide enomxholo we-9Chemicalbook9.5%, ubushushu bokusabela yi-90°C, kwaye uxinzelelo yi-2.53MPa. Thatha i-140.75kg yomxube oqulethe i-80.5% (inxalenye yobunzima) ye-monomethylamine ngeyure nganye, oko kukuthi, ubungakanani bemveliso ye-N-methylformamide yi-113.4kg ngeyure, kwaye amandla emveliso ye-reactor ye-1L yi-1.89kg ye-N-methylformamide ngeyure.
