Abstract
AbstractBroad‐ and narrow‐range dodecanol ethoxylates were obtained with sodium hydroxide and a proprietary calcium‐based catalyst, respectively. The proprietary catalyst was also used for direct ethoxylation of methyl dodecanoate ester. Natta‐Mantica distribution coefficients were calculated from the fractional content of the reaction products. A specific sequence of the distribution coefficients was observed in each case. A superior activation of the second addition step in ethoxylation of the methyl dodecanoate ester was noted. The kinetic pattern of the reaction resulted in a product distribution specifically related to the average degree of oxyethylation degree.
