Abstract

The invention is a continuous process for the preparation of polytrimethylene ether glycol from 1,3-propanediol reactant. In addition, the invention is directed to a continuous multi-stage process comprising reacting at least one reactant in a liquid phase in an up-flow column reactor, and forming a gas or vapor phase by-product wherein the gas or vapor phase by-product is continuously removed at the top and at least one intermediate stage.

Claims (18)

1. A process of making polytrimethylene ether glycol comprising:
(a) providing 1,3-propanediol reactant and polycondensation catalyst; and (b) continuously polycondensing the 1,3-propanediol reactant to polytrimethylene ether glycol.
2. The process of claim 1 wherein the polycondensing is carried out at a temperature of 150-250°C.
3. The process of claim 1 wherein the temperature is of 160-210°C.
4. The process of any of claims 1-3 wherein the polycondensation is carried out at a pressure of less than 500 mm Hg.
5. The process of claim 4 wherein the pressure is less than 250 mm Hg.
6. The process of any of the preceding claims wherein the 1,3-propanediol reactant is selected from the group consisting of 1,3-propanediol and/or dimer and trimer of 1,3-propanediol and mixtures thereof.
7. The process of any of claims 1-5 wherein the 1,3-propanediol reactant is selected from the group consisting of the 1,3-propanediol or the mixture containing at least 90 weight % of 1,3-propanediol.
8. The process of any of claims 1-5 wherein the 1,3-propanediol reactant is the 1,3-propanediol.
9. The process of any of the preceding claims wherein the reactor has 3-30 stages.
10. The process of any of the preceding claims wherein the reactor has 8-15 stages.
11. The process of any of the preceding claims wherein the polycondensation is carned out in an up-flow co-current column reactor and the 1,3-propanediol reactant and polytrimethylene ether glycol flow upward co-currently with the flow of gases and vapors.
12. The process of claim 11 wherein the 1,3-propanediol reactant is fed at multiple locations to the reactor.
13. The process of claim 11 or 12 wherein at least some amount of steam (water vapor) that is generated as a by-product of the reaction is removed from the reactor at least one intermediate stage.
14. The process of any of claims 1-10 wherein the polycondensation is carried out in a counter current vertical reactor wherein and the 1,3-propanediol reactant and polytrimethylene ether glycol flow in a manner counter-current to the flow of gases and vapors.
15. The process of any of the preceding claims wherein the 1,3-propanediol reactant is fed at multiple locations to the reactor.
16. The process of any of the preceding claims wherein the polycondensation is first carried out in at least one prepolymerizer reactor and then continued in a column reactor, the 1,3-propanediol reactant comprises 90 weight % or more 1,3-propanediol, and in the prepolymerizer reactor the 1,3-propanediol is polymerized with the catalyst to a degree of polymerization of at least 5.
17. The process of claim 16 wherein in the at least one prepolymerizer reactor the 1,3-propanediol is polymerized with the catalyst to a degree of polymerization of at least 10 and the column reactor comprises 3-30 stages.
18. A continuous multi-stage process comprising reacting at least one reactant in a liquid phase in an up-flow column reactor, and forming a gas or vapor phase by-product wherein the gas or vapor phase by-product is continuously removed at the top and at least one intermediate stage.
