Abstract

Procedeul de obtinere a gazolinei din amestecurile apoase care o contin, conform inventiei, este un procedeu îmbunatatit de producere de gazolina cu concentratie de alcooli C2...C4 din amestecuri apoase care contin alcoolii respectivi, îmbunatatirea constînd în aceea ca amestecul apos este facut sa reactioneze cu o olefina tertiara, în prezenta unui catalizator acid, la o temperatura cuprinsa în intervalul de la 40 pînp la 90 degree C si la o viteza spatiala cuprinsa între 5 si 25 l de reactanti pe litrul de catalizator si ora. Catalizatorii preferati sunt rasini schimbatoare de ioni-forma acida, în special acele grupe -SO3H, intervalul de temperatura si viteza spatiala fiind critice, cu scopul de a reduce la minimum reactiile de formare a esterilor parazitari.
