Abstract

Compozitie catalitica folosita la obtinerea acizilor nesaturati, formata din oxizi de molibden, vanadiu si wolfram în proportii bine definite, caracterizata prin aceea ca în scopul maririi randamentului concomitent cu mentinerea unor grade de conversie ridicate, contine oxid de germaniu sau litiu în astfel de proportii încît sa corespunda formulei empirice: (vezi formula) în care Me reprezinta litiu, IV reprezinta germaniu, iar simbolurile a,b,c,d,g si x, reprezinta numarul de atomi ai elementelor care intra în constitutia amestecului si sunt egale cu: a=12; b=0,1...12; c=0...6; d=0...2; g=0,5...5, x are valoarea necesara satisfacerii valentelor elementelor care intra în constructia amestecului catalitic.Catalytic composition used to obtain unsaturated acids formed from oxides of molybdenum, vanadium and tungsten in well-defined proportions, characterized in that in order to increase the yield while maintaining high conversion rates, it contains germanium oxide or lithium oxide in such proportions that correspond to the empirical formula: where Me represents lithium, IV represents germanium, and the symbols a, b, c, d, g and x represent the number of atoms of the elements that enter into the constitution of the mixture and are equal to: a = 12; b = 0,1, ... 12; c = 0 ... 6; d = 0 ... 2; g = 0.5 ... 5, x is the value required to satisfy the valences of the elements entering the catalytic mixture.
