| 20140088329 | PROCESS FOR THE PRODUCTION OF CHLORINATED AND/OR FLUORINATED PROPENES - Processes for the production of chlorinated and/or fluonnated propenes provide good product yield with advantageous impurity profiles in the crude product. Advantageously, the processes may be conducted at lower temperatures than 600° C., or less than 500° C., so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants. | 03-27-2014 |

| 20140275660 | METHOD FOR MITIGATING HCL GENERATION DURING 1,1,2,3-TETRACHLOROPROPENE PURIFICATION - This invention is directed to a method for mitigating HCl generation during 1230xa purification, which comprises the steps of; (a) adding a chelating agent into 1230xa crude, and (b) conducting the 1230xa purification in the presence of said chelating agent at a quantity sufficient to reduce or prevent 1230xa decomposition. Examples of chelating agent include tributyl phosphate (TBP), tripropyl phosphate (TPP), and triethyl phosphate (TEP). The concentration of chelating agent in 1230xa crude can range from 0.001 to 20 wt %, preferably from 0.01 to 10 wt %, and more preferably from 0.1 to 5 wt %. | 09-18-2014 |
| 20150353452 | METHOD FOR HEAT RECOVERY IN VINYL CHLORIDE MONOMER STRUCTURES OR IN THE STRUCTURE COMPOSITE DICHLOROETHANE/VINYL CHLORIDE, AND DEVICE SUITABLE FOR SAME - Energy savings in an integrated DCE/VCM plant, optionally also containing a PVC plant, is accomplished by using at least part of the vapor from a DEC quenching column to supply heat to an HCl column. The DCE plant has a high boiler column operating at superatmospheric pressure, and heat is removed from an overhead stream and used to supply heat to other portions of the process. | 12-10-2015 |

| 20120226081 | METHOD TO PURIFY AND STABILIZE CHLOROOLEFINS - The present invention is directed towards a method of purification of chloroolefins having 3 carbons and to a method to provide stable compositions of chloroolefins having 3 carbons. The chloroolefins are purified via the use of a solid absorbents for the removal of decomposition product such as phosgene and/or phosgene precursory from the reaction of the chloroolefins with oxygen. The chloroolefins stabilized against an increase of the phosgene level via the addition of inhibitors to the chloroolefins. | 09-06-2012 |
