Isovoihappo (CAS 79-31-2)<\/strong><\/p>\n

Isovoihappo, joka tunnetaan my\u00f6s nimell\u00e4 2-metyylipropaanihappo tai isobutaanihappo, on karboksyylihappo, jonka rakennekaava on (CH3)2CHCOOH. Se on n-voihapon isomeeri. Se luokitellaan lyhytketjuiseksi rasvahapoksi. Deprotonointi tai ester\u00f6inti tuottaa johdannaisia, joita kutsutaan isobutyraatteiksi.<\/p>\n

Isovoihappo on v\u00e4rit\u00f6n neste, jolla on hieman ep\u00e4miellytt\u00e4v\u00e4 haju. Se liukenee veteen ja orgaanisiin liuottimiin. Sit\u00e4 esiintyy luonnostaan johanneksenleip\u00e4puussa (Ceratonia siliqua), vaniljassa ja Arnica dulcis -juuressa sek\u00e4 etyyliesterin\u00e4 krotoni\u00f6ljyss\u00e4.<\/p>\n

Tuotanto<\/strong>
\nIsovoihappoa valmistetaan hapettamalla isobutyyrialdehydi\u00e4, joka on propeenin hydroformylaation sivutuote.<\/p>\n

Se voidaan valmistaa my\u00f6s korkeapainehydrokarboksylaatiolla (Koch-reaktio) propeenista: CH3CH=CH2 + CO + H2O \u2192 (CH3)2CHCO2H<\/p>\n","protected":false},"featured_media":23473,"template":"","meta":[],"product_brand":[],"product_cat":[180,120],"product_tag":[],"class_list":["post-23431","product","type-product","status-publish","has-post-thumbnail","product_cat-uncategorized-fi-2","product_cat-laaketeollisuus","pif-has-gallery","first","instock","taxable","shipping-taxable","purchasable","product-type-variable","has-default-attributes"],"yoast_head":"\nIsovoihappo (CAS 79-31-2) -
