Abstract
Narrow, balanced alkoxylation product mixture distributions having at least one alkoxylation product constituting more than 20 weight percent of the mixture can be provided by modified, calcium-containing catalysts. Catalysts for alkoxylation processes can be produced from lime and can, with modification, be used to make the narrow, balanced alkoxylation product mixture distribution.
