Abstract
Abstract A process is provided for the preparation of soluble basic salts of alkaline earth metals that are catalytically active in the oxyalkylation reaction of alcohols, polyols and phenols which comprises reacting an alkaline earth metal material selected from the group consisting of calcium, strontium, and barium and mixtures of the same with a lower monohydric alcohol having 1 to 7 carbon atoms at a temperature at which the reaction proceeds to form a lower alcohol metal alkoxide, mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol-alkaline earth metal alkoxide reaction product and removing the lower alcohol therefrom.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
A process for preparing catalytically active soluble basic salts of alkaline earth metals which comprises reacting an alkaline earth metal material selected from the group consisting of calcium, strontium, and barium, and mixtures of the same with a lower monohydric alcohol having 1 to 7 carbon atoms at a temperature at which the reaction proceeds to form a lower alcohol metal alkoxide; mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol-alkaline earth metal alkoxide reaction product and removing the lower alcohol therefrom.
Claim 2
Dependent Claim
91 words
A process for preparing catalytically active soluble basic salts of alkaline earth metals which comprises reacting an alkaline earth metal material selected from the group consisting of calcium, strontium, and barium, and mixtures of the same with a lower monohydric alcohol having 1 to 7 carbon atoms at a temperature at which the reaction proceeds to form a lower alcohol metal alkoxide; mixing a polyol or a higher monohydric alcohol having at least 4 carbon atoms with the lower alcohol-alkaline earth metal alkoxide reaction product and removing the lower alcohol therefrom.
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-alkaline earth metal alkoxide reaction product is an amount sufficient to convert all of the lower alcohol metal alkoxide.
Claim 4
Dependent Claim
29 words
The process of claim 1 in which the concentration of alkaline earth metal in the lower alcohol reaction mixture is from about 0.01 to about 20 percent by weight.
Claim 5
Dependent Claim
20 words
The process of claim 1 in which a polyol is mixed with the lower alcohol-alkaline earth metal alkoxide reaction mixture.
Claim 6
Dependent Claim
23 words
The process of claim 4 in which the polyol has from 2 to 30 carbon atoms and from 2 to 6 hydroxyl groups.
Claim 7
Dependent Claim
21 words
The process of claim 1 in which a higher alcohol is mixed with the lower alcohol-alkaline earth metal alkoxide reaction mixture.
Claim 8
Dependent Claim
17 words
The process of claim 6 in which the higher alcohol has between 8 and 30 carbon atoms.
Claim 9
Dependent Claim
18 words
A soluble basic salt of alkaline earth metals which comprises the product of the process of claim 1.
