  Barium oxide is used as an ethoxylation catalyst for the reaction of ethylene oxide and alkanols of all classes. The reaction is carried out at temperatures of from about 200 to about 500° F to yield the ethoxylated product. The product abtained has a very narrow, high adduct distribution with low levels of by-products and unreacted free alcohols. Calcium and magnesium oxides show no catalytic effect.

  Basic compounds of strontium catalyzed the ethoxylation of alcohols in the presence of phenol or alkylphenol co-catalyst. Strontium-produced ethoxylates have sharper ethylene oxide distributions, lower free alcohol, lower pour points, and better detergency than the ethoxylates obtained from alkali base catalysis.
