N,N-Dimethylacetamide CAS 127-19-5
ʻO N, N-Dimethylacetamide, i ʻike ʻia ʻo Acetyldimethylamine a i ʻole Acetyldimethylamine, i hoʻopau ʻia ʻo DMAC, he mea hoʻoheheʻe polar non proton me kahi ʻala amonia liʻiliʻi a me ka solubility ikaika. Hiki iā ia ke hoʻoheheʻe i nā ʻano mea like ʻole, me ka wai, nā mea ʻala, nā esters, nā ketones, nā ʻawaʻawa, nā ethers, benzene, a me trichloromethane, a hiki ke hoʻōla i nā molekala hui. No laila, hoʻohana nui ʻia e like me ka solvent a me ka catalyst.

Hoʻohana ʻia ʻo N, N-Dimethylacetamide ma ke ʻano he mea maka no nā fibers synthetic a me kahi solvent polar maikaʻi loa no ka synthesis organik. Hoʻohana ʻia ʻo N, N-Dimethylacetamide i ka synthesis organik, a me ke ʻano he solvent, catalyst, a me ka wehe ʻana i ka pena. N, N-Dimethylacetamide hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe ʻana no ka hoʻohui ʻana i ka lāʻau, he mea hoʻoheheʻe no ka wili ʻana o ka fiber synthetic a me ka resin synthesis, he mea hoʻoheheʻe no nā kala kemika photosensitive, a he mea hoʻoheheʻe no ka uhi. mea hoʻopāpā.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
