Abstract

Provided are azeotropic or azeotrope-like mixtures of 1,3,3,3-tetrachloroprop-1-ene (HCO-1230zd) and hydrogen fluoride. Such compositions are useful as a feed stock in the production of HFC245fa and HCFO1233zd.

Claims (11)

1. A composition consisting of 1,3,3,3-tetrachloroprop-1-ene (HCO-1230zd) and hydrogen fluoride, wherein the amount of hydrogen fluoride in the composition ranges from about 5.4 to about 92 weight percent and wherein the composition is a heterogeneous binary azeotrope or azeotrope-like composition.

2. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 5.4 weight percent.

3. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 15.8 weight percent.

4. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 28.4 weight percent.

5. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 40.3 weight percent.

6. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 50.1 weight percent.

7. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 55.7 weight percent.

8. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 66.1 weight percent.

9. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 80.7 weight percent.

10. The composition of claim 1 , wherein the amount of hydrogen fluoride in the composition is 92.0 weight percent.

11. A composition consisting of 14.4 g of 1,3,3,3-tetrachloroprop-1-ene (HCO-1230zd) and 14.4 g of HF, wherein the composition is a heterogeneous binary azeotrope or azeotrope-like composition which has a boiling point of about 0° C. at a pressure of about 13.3 psia.
