\u00c4ttiksyra 50 % (CAS 64-19-7)<\/strong> <\/p>\n

\u00c4ttiksyra eller etansyra \u00e4r en karboxylsyra med en karboxylgrupp. Det \u00e4r en klar, stickande luktande, fr\u00e4tande vattenblandbar v\u00e4tska. Strukturformeln f\u00f6r \u00e4ttiksyra \u00e4r CH3COOH och den kemiska formeln \u00e4r C2H4O2. \u00c4ttiksyra \u00e4r en svag monoprotisk syra med en syrakonstant p\u00e5 1,75 \u00d7 10-5 (pKa 4,75). Dess konjugatbas \u00e4r acetatjonen (CH3COO\u2212). Hush\u00e5llsvin\u00e4ger \u00e4r en utsp\u00e4dd l\u00f6sning av \u00e4ttiksyra. Vattenfri eller mer \u00e4n 80 massprocent \u00e4ttiksyral\u00f6sning kallas is\u00e4ttika. Vattenfri \u00e4ttiksyra kristalliserar redan vid 16,7 \u00b0C, dvs bara lite under rumstemperatur. Den mol\u00e4ra massan av \u00e4ttiksyra \u00e4r 60,1 g\/mol, sm\u00e4ltpunkt 16,7 \u00b0C, kokpunkt 118 \u00b0C, densitet (vid 20 \u00b0C) 1,05 g\/cm3 (vatten = 1,0 g\/cm3), flampunkt 39 \u00b0C c.c. , Sj\u00e4lvant\u00e4ndningstemperatur 427 \u00b0C och CAS-nummer 64\u201319\u20137. \u00c4ttiksyrasalter och estrar kallas acetater.<\/p>\n

\u00c4ttiksyra \u00e4r en av de viktigaste r\u00e5varorna i den kemiska industrin. Det anv\u00e4nds bland annat som livsmedelstillsats (E260), vid tillverkning av m\u00e5nga l\u00e4kemedel (som acetylsalicylsyra), parfymer, tryckf\u00e4rger, plaster, cellulosaacetat, mjukg\u00f6rare och acetatfibrer. I Finland anv\u00e4nds \u00e4ttiksyra bland annat f\u00f6r framst\u00e4llning av f\u00f6ljande kemikalier: karboximetylcellulosa (CMC), per\u00e4ttiksyra (C2H4O3) och klor\u00e4ttiksyra (C2H3ClO2).<\/p>\n","protected":false},"featured_media":11412,"template":"","meta":[],"product_brand":[],"product_cat":[105,116,173],"product_tag":[150,152],"class_list":{"0":"post-11388","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-hushallskemikalier-sv","7":"product_cat-alla-produkter","8":"product_cat-godselmedel","9":"product_tag-kotitalouskemikaalit-sv","10":"product_tag-lasikuitu-sv","12":"first","13":"outofstock","14":"featured","15":"taxable","16":"shipping-taxable","17":"purchasable","18":"product-type-variable","19":"has-default-attributes","20":"rtwpvg-product"},"yoast_head":"\n\u00c4ttiksyra 50 % (CAS 64-19-7) -
