摘要： An improved polymerization process wherein starting material such as monomer, a mixture of monomers, a partially polymerized product, or a mixture of fully polymerized product and monomer or monomer mixture is reacted with an initiator such as an organic peroxide, hydroperoxide or perester and a quaternary ammonium salt under polymerization conditions wherein polymerization or further polymerization of the starting material is initiated. The initiator and quaternary ammonium salt are miscible with the polymerization mixture in the absence of solvent. An improved polymerization process is also provided wherein a crosslinked polymer structure is formed from an unsaturated polymer in a polymerizable monomer.

摘要： The instant invention relates to a method for converting phosphorus containing polymers from a two dimensional, layered structure into a three dimensional structure by crosslinking such layers. The method and the resulting crosslinked polymers may be used to encapsulate active materials such as catalysts, pesticides, etc. by intercalating such active materials between the layers prior to crosslinking. Thus, the egress of said active materials into the environment during use may be hindered or prevented. The crosslinking polymers, themselves, may also be used as catalysts or as selective sorbents.

摘要： Magnesium and aluminum impurities are removed from aqueous phosphoric acid by treatment with a fluorine material and an alkali metal containing material in such a manner that the atomic ratio of fluorine to aluminum is adjusted so that it is greater than about 2 and the alkali metal plus magnesium to aluminum atomic ratio to a value no greater than about 2. In one embodiment the fluorine to aluminum ratio is below about 11, preferably between about 4 and about 8. By controlling such atomic ratios in the limits prescribed, a more purified aqueous phosphoric acid can be produced having a substantial reduction in the magnesium and aluminum content thereof. The process is useful for wet-process phosphoric acids. The process is also particularly useful for acids having low P.sub.2 O.sub.5 content and/or high aluminum concentration. The purification process does not require evaporation for the removal of impurities, as for example fluorine as silicon tetrafluoride.

摘要： In a process for the reduction of titanium salt comprising a halide of titanium to titanium metal by contacting said titanium salt in the molten state with a molten alloy and zinc to form a solution of titanium metal in zinc the improvement which comprises the step of:(a) contacting said titanium salt in the molten state with said molten alloy at an elevated pressure to thereby increase the solubility of said titanium metal in said solution.For example, an ore comprising titanium oxides may be fluorinated to convert the titanium oxides to titanium fluorides and the titanium fluorides may be reduced to titanium metal by contacting a molten titanium fluoride salt with a molten zinc-aluminum alloy at an elevated pressure to provide a titanium-zinc alloy having a greater concentration of titanium than is obtained at ambient pressure. The titanium-zinc alloy may be separated from the resulting fluorides of aluminum and the zinc distilled from the alloy to leave behind titanium sponge. The ore may be an ilmenite ore and the fluorination may be carried out by contacting said ilmenite ore with a fluosilicate salt such as sodium fluosilicate.

摘要： A method for igniting an in situ oil shale retort containing a fragmented permeable mass of formation particles containing oil shale is provided. A void space is in the retort between the top surface of the fragmented mass and the top boundary of overlying unfragmented formation. A hot ignition gas comprising oxygen is introduced into the void space to form a combustion zone across the surface of the fragmented mass. An oxygen-supplying gas is then introduced into the void space for sustaining the combustion zone and for advancing the combustion zone downwardly through the retort. The combustion zone is then extinguished and a cool inert gas is introduced into the retort to cool carbonaceous materials comprising the surface of the fragmented mass to a temperature below the self-ignition temperature of such carbonaceous materials, while leaving carbonaceous materials below the fragmented mass surface at temperatures greater than the self-ignition temperature of such materials. Introduction of the inert gas is then discontinued. Thereafter, an oxygen-supplying gas is re-introduced into the retort to ignite the carbonaceous materials below the surface of the fragmented mass for re-establishing the combustion zone in the fragmented mass and for advancing the combustion zone downwardly through the retort.

摘要： A process for producing phosphorus pentoxide from phosphate ore includes the mixing and formulation of a feed mixture of phosphate ore with lime and solid carbonaceous material in amounts to produce a feed mixture having a CaO/SiO.sub.2 mole ratio greater than about 8.0. This mixture is formed into pellets which are then exposed to radiation eminating from an oxidation zone, preferably within a rotary type kiln, in order to heat the pellets to a temperature sufficient to reduce the phosphate by reaction with the solid carbonaceous material to form elemental phosphorus vapor without substantial melting of the pellets. Sufficient oxygen-containing gas is provided to cause oxidation of the elemental phosphorus vapor within the oxidation zone to produce phosphorus pentoxide.
