    Abstract: Fumigant compositions including hexafluoropropene or 1,1,3,3,3-pentafluoropropene, and methods of preparing such compositions, are provided herein. The fumigant compositions may be suitable for use as soil fumigant compositions and structural fumigant compositions against a variety of undesirable species such as weeds, nematodes, pathogens, animals and insects. The fumigant compositions also have low toxicity and low Global Warming Potential.

    Abstract: The present invention is related to making hydrofluorocarbons (HCFCs), more specifically, 3,3,3-trifluoropropyne (TFP), from trans-1-chloro-3,3,3-trifluoropropene (trans-1233zd) by contacting the trans-1233zd with a base. Preferably, the base is potassium hydroxide or potassium tert-butoxide, which may or may not be dissolved in as solvent.

    Abstract translation: 本发明涉及通过使反式-1-氯-3,3,3-三氟丙烯(反式 - 1233zd)与反式-1-氯-3,3,3-三氟丙烯(反式 - 1233zd)反应制备氢氟烃(HCFC),更具体地说是3,3,3-三氟丙炔(TFP) 1233zd与基地。 优选地,碱是氢氧化钾或叔丁醇钾,其可溶解或不溶于溶剂。
