Abstract
Ethoxylation of alcohols, alkylphenols, and alkylamines has been studi ed in the presence of a few catalytic systems. Distribution constants were computed. Broad-range distributed ethoxylates are formed in the p resence of NaOH, and the distribution constants increase up to the hom ologue containing six oxyethylene units. Narrow-range distributed etho xy lates are formed in the presence of calcium-based catalysts. It is reflected in the values of the distribution constants because an incre ase with the growing number of oxyethylene units in successive homolog ue is not observed.
