Abstract
Abstract A process is provided for preparing soluble basic salts of barium that are catalytically active in the oxyalkylation reaction of reactive hydrogen compounds which comprises reacting barium oxide with a lower monohydric alcohol having 1 to 4 carbon atoms at a temperature at which the reaction proceeds to form a basic barium specie that is soluble in the lower alcohol; mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol-barium oxide reaction product and removing the lower alcohol from the reaction mixture.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
A process for the preparation of soluble basic salts of barium that are catalytically active in the oxyalkylation reaction of alcohols, polyols, and phenols which comprises reacting barium oxide with a lower monohydric alcohol having 1 to 4 carbon atoms at a temperature at which the reaction proceeds to form a basic barium specie soluble in the lower alcohol; mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol"barium oxide reaction product and removing the lower alcohol from the reaction product.
Claim 2
Dependent Claim
89 words
A process for the preparation of soluble basic salts of barium that are catalytically active in the oxyalkylation reaction of alcohols, polyols, and phenols which comprises reacting barium oxide with a lower monohydric alcohol having 1 to 4 carbon atoms at a temperature at which the reaction proceeds to form a basic barium specie soluble in the lower alcohol; mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol"barium oxide reaction product and removing the lower alcohol from the reaction product.
Claim 3
Dependent Claim
37 words
The process of claim 1 in which the amount of polyol or higher alcohol added to the lower alcohol-barium oxide reaction product is an amount sufficient to convert all of the lower alcohol basic salt of barium.
Claim 4
Dependent Claim
27 words
The process of claim 1 in which the concentration of barium in the lower alcohol reaction mixture is from about 0.01 to about 20 percent by weight.
Claim 5
Dependent Claim
17 words

Claim 8
Dependent Claim
25 words
