Abstract: Disclosed is a method of making chlorinated hydrocarbons. A mixture is prepared of a hydrocarbon or partially chlorinated hydrocarbon from C.sub.18 to C.sub.30 and either benzotrifluoride or parachlorobenzotrifluoride in an amount sufficient to liquefy the mixture at the chlorination temperature. The mixture is heated to a temperature of about 50.degree. to 100.degree. C. and sufficient chlorine gas is passed therethrough in the presence of UV light to form a chlorinated hydrocarbon that is about 60 to about 80 wt. % chlorine. One part by weight of the composition is added to at least two parts by weight per part of a C.sub.1 to C.sub.6 monohydric alcohol, which results in the precipitation of the chlorinated hydrocarbon. The precipitated chlorinated hydrocarbon can be removed from the composition by, for example, filtration.

Abstract: Disclosed is a mixture of about 10 to about 60 volume percent monochlorobenzotrifluoride, about 10 to about 60 volume percent monochlorotoluene, and about 20 to about 60 volume percent perchloroethylene. Also disclosed is a mixture of about 10 to about 30 volume percent monochlorobenzotrifluoride, about 40 to about 60 volume percent monochlorotoluene, and about 30 to about 50 volume percent perchloroethylene. The mixtures are used as solvents to form coatings of organic polymers and to clean parts.

Abstract: Disclosed is a method of removing chlorine from a mixture of gases. The mixture of gases is contacted with a liquid which contains a compound having the general formula ##STR1## where n is 1 to 3, whereby chlorine in the mixture of gases is absorbed by the liquid. The liquid is then heated to volatilize the chlorine and separate it from the liquid.

Abstract: Disclosed is a method of removing synthetic and natural resins from an article containing an epoxy resin without damaging the epoxy resin. The article is contacted with a solvent having the formula ##STR1## where n is 1 or 2, which dissolves the synthetic and natural resins and forms a solution. The solution is then separated from the article. The solvent can be recovered from the solution.

Abstract: Disclosed is a method and degreasing apparatus for cleaning articles. The articles are contacted with a chlorinated benzotrifluoride liquid which is subsequently washed from the articles using liquid methylene chloride. The degreaser includes means for applying the liquids to the articles and can also include means for evaporating some of the methylene chloride to render vapors of the chlorinated benzotrifluoride nonflammable.

Abstract: Disclosed is a mixture of about 1 to about 99 volume percent monochlorotoluene and about 1 to about 99 volume percent monochlorobenzotrifluoride. Also disclosed is a mixture of about 10 to about 60 volume percent monochlorotoluene, about 10 to about 60 volume percent monochlorobenzotrifluoride, and about 30 to about 60 volume percent perchloroethylene. The mixtures are used as solvents to form coatings of organic polymers and to clean parts.

Abstract: Disclosed is a composition of about 25 to about 85 wt % perchloroethylene and about 15 to about 75 wt % monochlorotoluene. When the composition contains at least about 30 wt % perchloroethylene it does not display a flash point.

Abstract: Decomposition of perchloroethylene is prevented by the addition of a stabilizer system containing N-substituted cyclic alkyl amine, alcohol of 3-7 carbon atoms and olefin components. The stabilizer system is advantageous in that it does not contain any environmentally undersirable materials.

Abstract: Dielectric fluid is prepared by combining perchloroethylene with an aliphatic hydrocarbon having 7-9 carbon atoms in the aliphatic chain. The resulting dielectric has improved freezing point and nonflammability characteristics.

Abstract: Strobe lag is identified as a major source of sensitivity in distinguishing acceptable and flawed glassware in bright field video inspection systems employing strobed light sources and video systems with vidicon tubes. By disabling video signal generation from the photoconductive target of the vidicon for several milliseconds beginning with initiation of the strobed light sources, less sensitive and more stable operation of the video inspection apparatus is achieved. The video signal is generated from the fully developed stored image on the photoconductive target.

Abstract: The removal of undesirable substances such as water, PCB's and air from the internal components of electrical devices such as transformers and power capacitors is efficiently and effectively achieved by contacting, in the absence of air, the internal components of these various electrical devices with a heat-stable fluid material. The heat-stable fluid materials are preferably halogenated aliphatic hydrocarbons and most preferably perchloroethylene or FREON 113.

Abstract: Electrical devices such as transformers and power capacitors are improved by the use of a dielectric fluid prepared by combining perchloroethylene having a low chlorinated ethane content with an antioxidant. This fluid has excellent resistance to decomposition over long periods of time and under severe operational conditions.

Abstract: A chromium-containing treating composition, which is especially useful for rinsing phosphatized metal surfaces, contains hexavalent chromium-containing compound, methylene chloride and a substance that can be acetamide, N,N-dimethylformamide, acetone oxime and mixtures thereof. The composition is a homogeneous solution that is particularly useful where aqueous systems may create potential water pollution problems.
