Abstract
Abstract A process is provided for the reaction of an organic compound having an active hydrogen such as alcohols, phenols, polyols, acids, and amines with epoxides in the presence of a basic salt of an alkaline earth metal selected from the group consisting of calcium, strontium, and barium which is soluble in the reactants and the reaction products to prepare products having a narrower molecular weight distribution.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
A process for the preparation of reaction products of an organic compound having an active hydrogen with an epoxide having a narrower molecular weight distribution which comprises reacting an organic compound having an active hydrogen selected from the group consisting of monohydric alcohols, phenols, polyols, mono-and dicarboxylic acids, and amines with an epoxide at a temperature at which the reaction proceeds in the presence of at least a catalytic amount of a basic salt of an alkaline earth metal selected from the group consisting of calcium, strontium, barium, and mixtures of the same which is soluble in the reactants and the reaction products or of a compound of an alkaline earth metal selected from the group consisting of calcium, strontium, barium, and mixtures of the same which is converted to the soluble basic salt thereof in situ.
Claim 2
Dependent Claim
137 words
A process for the preparation of reaction products of an organic compound having an active hydrogen with an epoxide having a narrower molecular weight distribution which comprises reacting an organic compound having an active hydrogen selected from the group consisting of monohydric alcohols, phenols, polyols, mono-and dicarboxylic acids, and amines with an epoxide at a temperature at which the reaction proceeds in the presence of at least a catalytic amount of a basic salt of an alkaline earth metal selected from the group consisting of calcium, strontium, barium, and mixtures of the same which is soluble in the reactants and the reaction products or of a compound of an alkaline earth metal selected from the group consisting of calcium, strontium, barium, and mixtures of the same which is converted to the soluble basic salt thereof in situ.
Claim 3
Dependent Claim
57 words
The process of claim 1 in which the catalyst is a soluble basic alkaline earth metal salt selected from the group consisting of calcium, strontium, and barium alkoxides, calcium, strontium, and barium amides, calcium, strontium, and barium phenoxides, and the mutual reaction product of a calcium, strontium, or barium hexammoniate, an olefin oxide and an organic nitride.
Claim 4
Dependent Claim
22 words
The process of claim 1 in which the organic compound is selected from the group consisting of monohydric alcohols, phenols, and polyols.
Claim 5
Dependent Claim
51 words
The process of claim 1 wherein said reactive hydrogen compound is a member selected from the group consisting of monohydric alcohols having from 8 to about 20 carbon atoms, an alkyl substituted phenol, and a difunctional polypropylene oxide polymer having an average molecular weight in the range of 1000 to 5000.
Claim 6
Dependent Claim
14 words
The process of claim 4 wherein said reactive hydrogen compound is a primary alcohol.
Claim 7
Dependent Claim
27 words
The process of any one of claims 1 to 5 wherein said epoxide is an alkylene oxide having from 2 to 4 carbon atoms or mixtures thereof.
Claim 8
Dependent Claim
26 words
The process of any one of claims 1 to 6 in which the catalyst is selected from the group consisting of calcium, strontium and barium alkoxides.
Claim 9
Dependent Claim
38 words
The process of any one of claims 1 to 7 in which the catalyst concentration is within the range of 0.001 percent and 10 percent by weight of alkaline earth metal based on the active hydrogen organic compound.
