An environmentally friendly composition and method which increase the API gravity, increase the solubility, and reduce the viscosity of hydrocarbon materials to provide enhance extraction and removal of the hydrocarbon materials for purposes of recovery or cleaning.

Composition and method for extracting, recovering, or removing hydrocarbon materials

A method of producing high purity germanium tetrafluoride comprising the step of flowing a mixture of inert gas and fluorine gas through a reactor chamber preferably containing germanium powder. The reactor effluent stream is conducted through at least one product trap effective for condensing and retaining at least a portion of the germanium tetrafluoride product. The product is preferably then purified by repeatedly subliming the product as necessary to remove volatile impurities.

Brazing fluxes comprising a combination of a fluoroaluminate complex and selected metal fluorosilicates, including their method of manufacture and use, are disclosed.

Brazing flux

Potassium tetrafluoroaluminate and potassium hexafluoroaluminate have been produced by three new processes: (a) by reacting alumina trihydrate with freshly produced, hot, solvated potassium fluoride or potassium bifluoride solution in presence of stoichiometric amounts and/or an excess of hydrogen fluoride, or (b) by reacting aluminum trifluoride trihydrate with hot aqueous solution in potassium fluoride or potassium bifluoride, or (c) by generating in situ potassium aluminate by reacting alumina trihydrate with hot aqueous potassium hydroxide and treating the same with aqueous or anhydrous hydrogen fluoride.
