N,N-Dimethylacetamide CAS: 127-19-5
Kemikari zvivakwa: Iyo makemikari zvimiro zvakafanana neN, N-dimethylformamide, uye inomiririra amide solvent. Mukushaikwa kweasidhi kana alkali, haizoora kana ichipisa kusvika pakufashaira pasi pekumanikidzwa kwakajairika, saka inogona kunyungudutswa pasi pekumanikidzwa kwakajairwa. The hydrolysis rate inononoka zvikuru. Apo N, N-dimethylacetamide ine 5% mvura inopisa pa 95 ° C kwemaawa 140, chete 0.02% ndiyo inonzi hydrolyzed. Nekudaro, pamberi peasidhi uye alkali, iyo hydrolysis rate inowedzera. Saponification inoitika kana inopisa muhupo hwealkali yakasimba.
Iyo yemhando yepamusoro-giredhi yakajeka fluid.
Nzvimbo yekushandisa
1. Pharmaceutical intermediate dimethylacetamide inokosha yemishonga yakasvibiswa uye inoshandiswa zvakanyanya mukugadzirwa kweamoxicillin, cephalosporins nemimwe mishonga. Sezvinonyungudutsa kana cocatalyst, dimethylacetamide inogona kuvandudza mhando yechigadzirwa uye goho kana ichienzaniswa neyechinyakare organic solvents. Muna 2000, kudiwa kwedimethylacetamide muindasitiri yemishonga yaive ingangoita 6kt. Iko kudiwa kwedimethylacetamide muna 2006 yaive ingangoita 9.6kt. 2. Acrylic fiber production Mukugadzirwa kwe acrylic fiber, vamwe vanoshandisa nzira ye dimethylacetamide. Parizvino, mudzimba acrylic fiber kugadzirwa Chemicalbook inonyanya kusanganisira sodium thiocyanate maviri-nhanho nzira, dimethylformamide imwe-nhanho nzira uye dimethylacetamide organic wet nzira zvinoenderana nezvinonyungudutsa. Kubva pamaonero emaitiro uye mashandisirwo emidziyo, kushandiswa kwezvinhu, kukanganisa kwezvakatipoteredza, mhando yechigadzirwa, Zvinhu zvakawanda senge post-processing performance, chiyero chenzvimbo uye mafambiro ebudiriro yekunze zvakawedzera tsvakiridzo yekushandisa uye kusimudzira kuedza. Dimethylacetamide yakashandiswa sekuenzanisa kwakazara. Sodium thiocyanate nzira mbiri-nhanho uye dimethylacetamide organic wet nzira yakashandiswa. Iyo inovimbisa budiriro. Parizvino, akawanda acrylic fiber kumisikidzwa muChina anoshandisa nyoro maitiro achishandisa dimethylacetamide sechinhu chinonyungudutsa.
