The composition is useful for the introduction of thiocyanate functionality into organic compounds in the same manner as thiocyanogen or thiocyanogen chloride, but is stable over longer periods of time, i.e. one year or more.

Abstract: It has now been found that certain phosphonate derivatives of bis(aminoalkyl) piperazines are good threshold agents to prevent metal ion precipitation in aqueous solutions. They also function as sequestering and/or chelating agents as do those which do not contain the phosphonate group.

Abstract: For measurement of chlorine concentration in a process stream, an improved device is set forth measuring light transmission in a selected frequency range. The preferred embodiment uses a light source, a light filter and an optical fiber extending to a pipe or other vessel with flowing chlorine. The light is transmitted from a lens system to another lens system and into a second optical fiber. The second fiber extends to a measuring device.

Abstract: An aqueous composition containing hydrogen peroxide, or a precursor which will form said peroxide in aqueous solution, is inhibited from decomposition in the presence of small amounts of copper, iron, manganese or other transition metal ions and in the presence of significant amounts of alkaline earth metal ions, e.g. Ca or Mg, by the presence of a combination of inhibitors one being from the group consisting of alkyleneaminephosphonic acids and the other being from the group consisting of polyalkylenepolycarboxylic acids and their analogous amides and sulfonic acid derivatives.

Abstract: New stable complexing agents for radionuclides which are phosphonate derivatives of certain polyamidoamines have been found which are useful in imaging the skeletal system in animals. Even though the complexing agents have high molecular weights the complexes clear rapidly and very efficiently through the kidneys, with large amounts being taken up in the bone. The ratio of uptake in bone to that in surrounding soft tissue is high even at relatively short times after injection.

Abstract: The process is an improvement over the chlorination of EDC in a boiling bed. The reactants, chlorine and dichloroethane (either 1,1- or 1,2-) are mixed in the vapor phase and passed over a molecular sieve which serves as a catalyst to produce 1,1,2-trichloroethane.

Abstract: A method of purifying 3-chloro-2-hydroxypropyl trialkylammonium chloride. An aqueous slurry is prepared containing about 70-98 wt. % total solids including the chloride and impurities associated with the preparation thereof. To this slurry is then added a miscible alcohol having about 3-4 carbon atoms. A solid filtrate is collected and optionally washed with additional alcohol and dried. The solid filtrate is substantially more pure in the chloride than the starting material.

Abstract: Stable methylchloroform solvent compositions in combination with from about 3 to about 5 volume percent of 2-butanol and from about 1 to about 3 volume percent of 3-methyl-1-butyn-3-ol have been shown to be superior solvents for removing flux from circuit boards. Such compositions have no flash point and maintain excellent distribution of the components in the vapor and liquid sections of the defluxing apparatus.

Abstract: The imaging of cardiac infarcts with complexed radioactive metals is improved by employing as the complexing agent a compound of the formula ##STR1## wherein substituents A, B, X and Y are each independently selected from radicals including hydrogen, hydroxyalkyl (wherein the alkyl group contains 2-6 carbon atoms), methylenephosphonic, methylene-, ethylene-, and propylenesulfonic, carboxylic acid radicals (having 2-4 carbon atoms) and the alkali or alkaline earth metal, ammonia and amine salts thereof and wherein at least one A, B, X and Y is methylenephosphonic acid or a salt thereof. In particular Tc-99m complexes have been found useful for imaging damaged cardiac tissue.

Abstract: An alumina support which contains cesium is prepared by adding a fusible compound of cesium to alumina along with known binders and porosity control agents. The cesium compound should be fusible below the temperature at which the alumina fuses. Such a support is especially useful as a support for a silver catalyst employed in the oxidation of ethylene to ethylene oxide.

Abstract: New compounds have been prepared from dicyclopentadiene bis(methylamine) which have the following formula ##STR1## wherein substituents A, B, X and Y each are independently selected from radicals including hydrogen, hydroxyalkyl (wherein the alkyl group contains 2-6 carbon atoms) phosphonic, sulfonic, hydroxyethyl- and hydroxypropylsulfonic, methylenephosphonic methylene-, ethylene- and propylenesulfonic, alkylcarboxylic acid radicals (having 2-4 carbon atoms) and the alkali or alkaline earth metal, ammonia and amine salts of any of the phosphonic, sulfonic or carboxylic acid derivatives. At least one of the substituents must be other than a hydrogen. These compounds are useful chelating agents and those containing the methylenephosphonic substituents are good threshold agents.

Abstract: A process of preventing precipitation of scale producing metal ions, e.g. calcium, from their aqueous solutions by adding an effective amount of a methylenephosphonic acid derivative of bis(methylamine)-norbornane. These compounds are effective in threshold amounts.

Abstract: Radionuclide complexes of phosphonate derivatives of bis(aminoalkyl)piperazine have been found which are useful for imaging and/or treating therapeutically the skeletal system to detect and treat bone tumors. These complexes clear readily through the kidneys and the ratio of uptake in bone to that in surrounding soft tissue is high.

Abstract: Distillation of the heavy waste stream from the manufacture of phenol via the cumene process provides an overhead stream containing phenol, acetophenone and 2-phenyl propionaldehyde. Extraction of the overhead stream with aqueous caustic removes the phenol and subsequent distillation of the remaining two components in the presence of a catalytic amount of caustic provides a substantially pure acetophenone distillate.

Abstract: Superior solder flux, e.g., rosin flux, removal compositions are disclosed which have no flash point and are substantially non-corrosive toward aluminum. These compositions consist of about 0.5 to less than 2% methanol with about 3 to 10% of one or more alcohols containing 2-5 carbon atoms the balance being an inhibited 1,1,1-trichloroethane, wherein percentages are based on volume of the total composition.
