Problems solved by technology

Either of these processes alone (let alone all of them in combination) can make the large-scale routine production of chlorinated propenes required to be suitable as feedstock for the production of downstream products prohibitively expensive

Abstract

Processes for the production of chlorinated propenes are provided. The processes proceed through the production of cyclic intermediate that is thereafter readily converted to a desired chloropropane, e.g., via selective pyrolysis. The process may be conducted using starting materials that are readily commercially available and / or that may be reacted safely in standard laboratory equipment so that capital cost savings may be seen. The process does not require the use of catalysts and yet, process conditions less extreme than many conventional processes for the production of chlorinated propenes are suitable, so that raw material and utility cost savings are also possible.

Description

technical field [0001] The present invention relates to a process for the production of chlorinated propenes. Background technique [0002] Hydrofluorocarbon (HFC) products are widely used in many applications including refrigeration, air conditioning, foam expansion, and as propellants in aerosol products, including medical aerosol devices. Although HFCs have been shown to be more climate friendly than the chlorofluorocarbon and hydrochlorofluorocarbon products they replace, they have now been found to exhibit a considerable global warming potential (GWP). [0003] The search for more acceptable alternatives to current fluorocarbon products has led to the emergence of hydrofluoroolefin (HFO) products. HFOs are expected to exert less impact on the atmosphere relative to their predecessors, in the form of little or no detrimental impact on the ozone layer and a much lower GWP than HFCs. Advantageously, HFOs also exhibit low flammability and low toxicity. [0004] As the en...
