Abstract: Method for traveling fluidized bed distillation of coarse ground tire scrap, rubber vulcanizate (also vulcanized rubber), in a mixture with coarse aggregate. The rubber and aggregates are charges to a vertical still equipped with power burners near the bottom to burn a portion of the carbonaceous residue and supply the needed heat for the distillation process. The volatile materials and the pyrolysis oil vapors are drawn at the top for recovery and processing. Fines are recovered and the aggregate still at elevated temperatures are recycled to the top of the column and reused again with additional ground rubber. Noncondensable gases resulting from the "pyrolysis oil" condensation and recovery system contain high heating value and can be used for combustion needs in the still, or for steam generation.

Abstract: The invention relates to a novel fluorinated pre-polymer and novel process steps in producing the same. The pre-polymers are quinoxaline materials derived by reaction of diketone linkage containing perfluoro-compounds with an aromatic diamine. The diketone is produced by oxidatively dechlorinating a polychloroketone which may be a monoketone or a bis-ketone. The polychloroketone is produced by reacting a keto-ylid with a chlorinating agent, e.g., chlorine. The keto-ylid is produced by reacting a phosphorane with an acid halide of a polyoxy-perfluoroalkylene oxide wherein the perfluoro-oxyalkylene group contains two or three carbon atoms, and there are present from two to twenty perfluoro-oxyalkylene units in the oligomer. The quinoxalines, the polychloroketones and the diketones hereof are novel products. Cross-linking may be effected with a free radical generator.

C., including the powdered metal, and an organic material having a surface tension of from 43 to 65 or higher dynes/cm. at 20.degree. C.

Abstract: There is provided a multi stage process for nonselectively chlorinating a titaniferous ore containing iron to produce TiCl.sub.4. In this process a portion of the ore charge is subjected to conventional fluid bed chlorination to produce TiCl.sub.4 and FeCl.sub.2. A second portion is subdivided and submitted to chlorination in a dilute phase chlorination step using FeCl.sub.3 as the chlorinating agent to produce additional TiCl.sub.4. The FeCl.sub.3 is obtained by partial oxidation of the FeCl.sub.2 obtained in the first stage and/or second stage to yield Fe.sub.2 O.sub.3 and FeCl.sub.3. The product streams of TiCl.sub.4 are then combined for further treatment.

Abstract: There is provided a process for the addition of a secondary aliphatic amine to myrcene or an 8-substituted myrcene and isomerization to a dialkyl 1,3-dienamine. The process is liquid phase and employs an excess of the amine relative to myrcene or substituted myrcene. The catalyst is an alkali metal amide anion formed from the amine.

Abstract: There is provided an improved process for chlorinating an iron-containing titaniferous ore, such as ilmenite which comprises dividing the ore charge into 2 parts. The first and major part is chlorinated with chlorine or with a mixture of chlorine and FeCl.sub.3 under fluidized bed conditions to yield principally TiCl.sub.4 and FeCl.sub.2. The FeCl.sub.2 is separated out and utilized as a chlorinating agent for the minor part of the ore in an entrained flow chlorinator to yield more TiCl.sub.4 and metallic iron as principal products. This process avoids the need for disposal of FeCl.sub.2 and retains the advantages of conventional chlorination procedures.

Abstract: An improvement in process for making cupreous catalyst composition, wherein a copper oxide-preponderant grind charge derived from the oxidation of elemental copper and/or an alloy thereof is subject to high energy milling with concomitant crystal lattice distortion until the average particle of the resulting grind is no larger than about 20 microns, comprises establishing a tin concentration between about 400 and about 3000 ppm in said composition prior to or after said high energy milling. The resulting catalyst is useful for producing organohalosilane from alkyl chloride and silicon.

Abstract: A grind charge of cupreous particulates containing a major proportion of cuprous and cupric oxides and a minor proportion of elemental copper, said charge having average particle size above 15 microns, is subjected to high energy comminution with concomitant crystal lattice distortion until the average particle size of said particulates is no larger than 15 microns. The resulting catalyst, of fairly high specific surface area, can be used for alkyl or aryl halosilane production.

Abstract: Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of hydrated refractory metal oxide such as hydrated alumina. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.

Abstract: Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of a hydroxide of Period IV metal having Atomic Number between 24 and 30, e.g. iron III oxide monohydrate. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.

Abstract: There is provided an improved process for producing biologically active arylterpenoid compounds useful to inhibit eclosion of pupae, e.g., fly pupae or mosquito pupae. The process is characterized by reacting a terpenoid material having a terminal unsaturated linkage, e.g., dihydromyrcene (3,7-dimethylocta-1,6-diene) with a lower alkyl Grignard reagent, e.g., n-propyl magnesium chloride to form a Grignard exchange product. The exchange product is then benzylated. Either a benzyl halide, e.g., p-isopropylbenzyl chloride, or a benzaldehyde, e.g., p-isopropylbenzaldehyde may be used. These compounds are specifically described in U.S. Pat. No. 4,002,769. They contain also a lower alkoxy group, e.g., methoxy. This can be introduced prior to the formation of the Grignard exchange product or at a later stage in the operation. Use of the exchange-type Grignard reaction enables elimination of several steps when producing the arylterpenoids from pinene as the terpene source, and consequent costs.

Abstract: A process and a product produced thereby, for forming rod or bar or tube stock or strip, comprising a sheath and a densified dispersion strengthened metal core. Powdered dispersion strengthened copper is put into a metal can and compressively reduced to size and density. The relationship between the tensile strength of the core when fully densified and the cold worked tensile strength of the can is important to the nature of the product.

Abstract: There is provided a new method for analysis of the size and/or distribution of particles emanating from a mother liquid by sedimentation in a rotating disc centrifuge, particularly a photosedimentometer. The method is characterized in that the spin fluid or medium is formed externally of the disc as distinct from being formed within the disc while it is rotating. The externally prepared spin medium is formed from at least two miscible liquids of different densities for example, methanol and water, in a manner such that they are substantially incompletely mixed whereby a density gradient is established in the spin medium. Thereafter the spin medium is injected into the disc while spinning at a given speed, and later the mother liquid is injected. Results are closely comparable to the buffered line start method described in U.S. Pat. No. 3,475,968.

There is also provided a method of stabilizing an emulsifiable tackifier composition which comprises adding to such composition, a minor amount of a surfactant and a minor amount of an elastomer.
