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:
The present invention generally relates to polymeric membrane materials formed, at least in part, from monomeric material selected from 2,3,3,3-tetrafluoropropene (CF3CF═CH2, HFO-1234yf) or trans-1,3,3,3-tetrafluoropropene (CF3CH═CFH, HFO-1234ze), and to membrane preparations and uses thereof in water desalination, filtration, membrane distillation, pervaporation, and selective gas separation.
Abstract:
In accordance with the present invention, processes for producing bromofluoropropenes in commercial quantities by reacting 3,3,3-trifluoropropyne with hydrogen bromide at elevated temperatures are provided.
