Kaliumklorid (CAS 7447-40-7) <\/strong> <\/p>\n

Kaliumklorid KCl \u00e4r ett f\u00e4rgl\u00f6st, hygroskopiskt, mycket vattenl\u00f6sligt och icke brandfarligt kristallint \u00e4mne som best\u00e5r av kalium och klor. Kaliumklorid har en molekylvikt p\u00e5 74,6 g\/mol, en sm\u00e4ltpunkt p\u00e5 770-773\u00b0C, en gl\u00f6dgningstemperatur p\u00e5 1 500\u00b0C, en densitet p\u00e5 1,98 g\/cm 3 (vatten = 1,0 g\/cm 3) och en CAS nummer 7447-40-7 . LD50 f\u00f6r oral kaliumklorid \u00e4r cirka 2,5 g\/kg. N\u00e4r det administreras direkt i en ven \u00e4r LD50 n\u00e5got \u00f6ver 100 mg\/kg (7,6 gram f\u00f6r 75 kg). H\u00f6ga doser orsakar hyperkalemi och \u00e5tf\u00f6ljande elektrisk st\u00f6rning av hj\u00e4rtmuskeln och ytterligare hj\u00e4rtstillest\u00e5nd. Det mesta av kaliumet i m\u00e4nniskokroppen finns i musklerna, d\u00e4r det fungerar som en elektrolyt f\u00f6r att \u00f6verf\u00f6ra nervimpulser. Hyperkalemi orsakad av en d\u00f6dlig dos av kaliumklorid st\u00f6r fl\u00f6det av nervimpulser i hj\u00e4rtmuskeln, vilket g\u00f6r hj\u00e4rtmuskeln f\u00f6r ledande, vilket g\u00f6r att nervimpulserna passerar direkt genom muskeln och hj\u00e4rtat inte l\u00e4ngre reagerar p\u00e5 dem. Detta g\u00f6r att hj\u00e4rtat stannar. F\u00f6r den medvetna orsakar det liknande sm\u00e4rtor som en hj\u00e4rtattack.<\/p>\n","protected":false},"featured_media":8422,"template":"","meta":[],"product_brand":[],"product_cat":[171,173,179,182,105,116],"product_tag":[],"class_list":{"0":"post-8419","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-livsmedelsindustrin","7":"product_cat-godselmedel","8":"product_cat-foderindustri","9":"product_cat-hortikultur","10":"product_cat-hushallskemikalier-sv","11":"product_cat-alla-produkter","13":"first","14":"outofstock","15":"taxable","16":"shipping-taxable","17":"purchasable","18":"product-type-variable","19":"has-default-attributes","20":"rtwpvg-product"},"yoast_head":"\nKaliumklorid (CAS 7447-40-7) - MasterChem | kemikaalien tuotanto ja myynti<\/title>\n<meta name=\"description\" content=\"Kaliumklorid (KCl eller kaliumsalt) \u00e4r ett metallhalidsalt som best\u00e5r av kalium och klor.
