Dimetyyliformamidi (CAS 68-12-2)<\/strong><\/p>\n

Dimetyyliformamidi on orgaaninen yhdiste, jonka kaava on (CH3)2NC(O)H. T\u00e4m\u00e4 v\u00e4rit\u00f6n neste sekoittuu veteen ja useimpiin orgaanisiin nesteisiin, lyhennet\u00e4\u00e4n yleisesti nimell\u00e4 DMF. DMF on yleinen liuotin kemiallisiin reaktioihin. Dimetyyliformamidi on hajuton, mutta teknisill\u00e4 tai hajoavilla n\u00e4ytteill\u00e4 on usein kalan haju dimetyyliamiinin ep\u00e4puhtauksien vuoksi. Dimetyyliamiinin hajoamisen ep\u00e4puhtaudet voidaan poistaa suihkuttamalla n\u00e4ytteit\u00e4 inertill\u00e4 kaasulla, kuten argonilla, tai sonikoimalla n\u00e4ytteet alipaineessa. Kuten nimi osoittaa, se on rakenteellisesti sukua formamidille, jossa on kaksi metyyliryhm\u00e4\u00e4 kahden vedyn tilalla. DMF on polaarinen (hydrofiilinen) aproottinen liuotin, jolla on korkea kiehumispiste. Se helpottaa polaarisia mekanismeja seuraavia reaktioita, kuten SN2-reaktioita.<\/p>\n","protected":false},"featured_media":23619,"template":"","meta":[],"product_brand":[],"product_cat":[180,286],"product_tag":[],"class_list":{"0":"post-23577","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-uncategorized-fi-2","7":"product_cat-maalit-ja-lakat","8":"pif-has-gallery","10":"first","11":"instock","12":"taxable","13":"shipping-taxable","14":"purchasable","15":"product-type-variable","16":"has-default-attributes"},"yoast_head":"\nDimetyyliformamidi (CAS 68-12-2) - Chemistry For Industry - Solvents & Chemicals - Masterchem.ee<\/title>\n<meta name=\"description\" content=\"Dimetyyliformamidi on orgaaninen yhdiste, jonka kaava on (CH3)2NC(O)H.
