GLYCEROL PROPOXYLATE-B-ETHOXYLATE Use and Manufacturing
1. A process for the production of polyether polyols having an average hydroxyl functionality of at least 3 and a hydroxyl number of from 28 to 1000 by alkoxylating a mixture comprising: (a) from 20 to 80% by weight of sucrose (based on the sum of (a) and (b)), and (b) from 80 to 20% by weight of formitol having an average hydroxyl functionality of at least 3 (based on the sum of (a) and (b)). 2. The process of claim 1 wherein the mixture comprises: (a) from 40 to 75% by weight of sucrose (based on the sum of (a) and (b)), and (b) from 60 to 25% by weight of formitol (based on the sum of (a) and (b)). 3. The process of claim 1 wherein the formitol has an average hydroxyl functionality of from 3.3 to 5.7. 4. The process of claim 1 wherein the mixture further comprises 0.5 to 3% by weight water (based on the total quantity of sucrose and formitol). 5. The process of claim 1 wherein the mixture further comprises 2-20% by weight of a compound taken from the group consisting of a low molecular weight polyol, mono-amine, poly-amine and mixtures thereof (based on the total quantity of sucrose and formitol). 6. The process of claim 1 wherein the mixture has an average functionality with respect to alkylene oxides of from 4 to 7.
