Abstract
Inventia se refera la un procdeu pentru obtinerea esteri,lor alchilici ai acizilor carboxilici alifatici saturati prin tratarea olefinelor reziltate din dehidrogenarea catalitica a parafinelor sau din clorurarea parafinelor urmata de dehidroclorurarea clorparafinelor cu oxid de carbon li alcanol în prezenta unui catalizator cu continut de cobalt si a unui promotor constînd din piridina si/sau alchilpiridina nesubstituita în proportia orto, la presiune si temperatura ridicata si recircularea substabnselor nereactionate, constînd din aceea ca în scopul mentinerii carcateristicilor optime ale reactiei de esterificare, se îndeparteaza apa din alcool sau promotorul recirculat pîna la mai putin de 0,1 procente în greutate fata de olefina introdusa, prin distilare azeotropa sau tratare cu agenti de adsoirbtie.
