Isingeniso somkhiqizo
I-N-Methylformamide (NMF) CAS：123-39-7
I-N-methylformamide emsulwa iwuketshezi olungenambala, olubonakalayo noluqinile, mp-3.8℃, bp198℃, n25D 1.4310, ukuminyana okuhlobene okungu-0.9986 (25℃), oluncibilikayo emanzini, lungancibilikisa nosawoti ongaphili, futhi luyi-hygroscopic. Lubola kalula ezixazululweni ezine-acidic noma ze-alkaline.
Indlela Yokukhiqiza 1. Indlela ye-Methylamine ikhiqizwa ukusabela kwe-methylamine ne-carbon monoxide. 2. Indlela ye-Methyl formate itholakala ukusabela kwe-methyl formate ne-methylamine. 3. Itholakala ekusabela kwe-ethyl formate ne-methylamine. Faka i-ethyl formate ku-reactor, engeza isixazululo samanzi se-methylamine ngaphansi kokupholisa, bese ubuyisela ukusabela ku-40°C. Ngemuva kwalokho kwashiywa izinsuku ezi-3, bese i-ethanol ibuyiswa ngaphansi kwengcindezi encishisiwe ukuze kutholakale umkhiqizo ongahluziwe. Umkhiqizo oqediwe utholakala ngokuhluzwa ngaphansi kwengcindezi encishisiwe.
Inkambu yohlelo lokusebenza
I-N-methylformamide iyinto ebalulekile yokwenziwa kwezinto eziphilayo. Isetshenziswa ekuhlanganiseni izibulala-zinambuzane, izibulala-zinambuzane kanye ne-acaricides i-monoformamidine kanye ne-diformamidine. Iphinde isetshenziswe ekukhiqizeni imithi, isikhumba sokwenziwa, isikhumba sokwenziwa, kanye nesinyibilikisi sezindwangu zefayibha yamakhemikhali.
