Claims (4)
1. Förfarande för framställning av en eventuellt sek- butanolhaltig blandning av sek-butyl-tert-butyleter och tert- butanol av butan, kännetecknat av att n-butan isomeriseras partiellt, butanerna dehydreras katalytiskt, butadien hydre- ras selektivt under omvandling av buten-1 tili buten-2, i de- hydreringsreaktionsblandningen förekommande isobuten omsätts med äterförd blandning av sek-butanol-vatten vid temperaturer o av 20-150 C i närvaro av sura katalysatorer tili tert-buta-nol och sek-butyl-tert-butyleter, varvid en sädan mängd isobuten tillsätts, att per 1 mol sek-butanol används 0,1-10 mol isobuten och per 1 mol vatten används 1-20 mol isobuten, och buten-2 i den icke omsatta huvudsakligen buten-2- och butan-haltiga kolväteblandningen omvandlas med vatten tili sek-butanol och denna äterförs tili företringsreaktionen.
2. Förfarande enligt patentkravet 1, kännetecknat av att isobutan efter företring och icke omsatt kolväte efter hydratisering dehydreras gemensamt med isomerisatet.
3. Förfarande enligt patentkravet 1 eller 2, kännetecknat av att genom rektifiering av reaktionsblandningen fr&n hydratiseringen separeras en blandning av vatten-sek-butanol, f rein denna separeras genom behandling med en isobutenhaltig C -fraktion en blandning innehällande sek-butanol och isobuten samt vatten genom extraktion, och företring utförs, under det att den frän sek-butanol och vatten befriade C - 4 . fraktionen äterförs tili extraktionen och vattenfasen fran extraktionen äterförs tili hydratiseringen.
