    Abstract: A method and system to remediate soil containing PFAS compounds and organic carbon. Total organic carbon is reduced by heating the soil at a sufficient temperature and for a sufficient duration to reduce surface effects between the PFAS compounds and the organic carbon to permit evaporation and treatment of the PFAS compounds from the soil.

    Abstract: A process is disclosed for producing 1,1,1,3,3,3-hexafluoropropane and/or 1,1,1,3,3-pentafluoropropene from (CF3)2CHCOOH and/or its water soluble salts. The process involves providing a mixture containing water and such carboxy compound(s) which has a pH of less than about 4, and reacting the mixture at a temperature of at least about 75 DEG C. Certain ether compounds may be included in the mixture along with (CF3)2CHCOOH and/or its water soluble salts. The reaction of the carboxy (and optionally ether) compound(s) with water may be employed in connection with a process for producing tetrafluoroethylene and/or hexafluoropropylene by pyrolysis, where by-product perfluoroisobutylene is reacted with water (and optionally an alkanol) to produce (CF3)2CHCOOH (and optionally one or more ether compounds).

    IPC: C07C17/363

    Abstract: Provided is a process for the manufacture of a fluorinated benzene derivative starting from benzoic acid derivative by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F2) is preferably present in a high concentration, and subsequent decarboxylation of the benzoic acid hypofluorite derivative obtained by direct fluorination. The fluorination process of the invention may be performed batch-wise or in a continuous manner. If the process is performed batch-wise, a column (tower) reactor may be used. If the process is continuous a microreactor may be used.
