Etikkahappo 50 % (CAS 64-19-7)<\/strong> <\/p>\n

Etikkahappo eli etaanihappo on karboksyylihappo, jossa on yksi karboksyyliryhm\u00e4. Se on kirkasta, pist\u00e4v\u00e4n hajuista, sy\u00f6vytt\u00e4v\u00e4\u00e4 veteen sekoittuvaa nestett\u00e4. Etikkahapon rakennekaava on CH3COOH ja kemiallinen kaava C2H4O2. Etikkahappo on heikko monoproottinen happo, jonka happovakio on 1,75 \u00d7 10-5 (pKa 4,75). Sen konjugaattiem\u00e4s on asetaatti-ioni (CH3COO\u2212). Kotitaloudessa k\u00e4ytett\u00e4v\u00e4 etikka on etikka\u00adhapon laimea liuos. Vedet\u00f6nt\u00e4 tai yli 80-massaprosenttista etikkahappoliuosta sanotaan j\u00e4\u00e4etikaksi. Vedet\u00f6n etikkahappo kiteytyy jo 16,7 \u00b0C:ssa eli vain v\u00e4h\u00e4n alle huoneenl\u00e4mp\u00f6tilan. Etikkahapon moolimassa on 60,1 g\/mol, sulamispiste 16,7 \u00b0C, kiehumispiste 118 \u00b0C, tiheys (20 \u00b0C:ssa) 1,05 g\/cm3 (vesi = 1,0 g\/cm3), leimahduspiste 39 \u00b0C c.c., itsesyttymisl\u00e4mp\u00f6tila 427 \u00b0C ja CAS-numero 64\u201319\u20137. Etikkahapon suoloja ja estereit\u00e4 nimitet\u00e4\u00e4n asetaateiksi.<\/p>\n

Etikkahappo on t\u00e4rkeimpi\u00e4 kemianteollisuuden raaka-aineita. Sit\u00e4 k\u00e4ytet\u00e4\u00e4n muun muassa elintarvikkeiden lis\u00e4aineena (E260), monien l\u00e4\u00e4keaineiden (kuten aspiriinin), hajuaineiden, painov\u00e4rien, muovien, selluloosa-asetaatin, pehmitinaineiden ja asetaattikuitujen valmistukseen. Suomessa etikkahappoa k\u00e4ytet\u00e4\u00e4n muun muassa seuraavien kemikaalien valmistukseen: karboksimetyyliselluloosa (CMC), peretikkahappo (C2H4O3) ja kloorietikkahappo (C2H3ClO2).<\/p>\n","protected":false},"featured_media":18832,"template":"","meta":[],"product_brand":[],"product_cat":[180,117,323],"product_tag":[],"class_list":{"0":"post-18784","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-uncategorized-fi-2","7":"product_cat-kotitalouskemikaalit","8":"product_cat-lannoitteet","9":"pif-has-gallery","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-variable","17":"has-default-attributes"},"yoast_head":"\nEtikkahappo 50 % (CAS 64-19-7) -
