摘要： A novel improved process for separating mixtures of 3- and 4-nitrophthalic acid is described. The said process comprises treating a mixture of 3- and 4-nitrophthalic acid, which mixture is free from inorganic acid residues, in an aqueous-organic medium containing 1-20 percent by volume of water, at a temperature of between 20.degree. and 100.degree. C., stepwise with a base capable of forming salts of 3- and 4-nitrophthalic acid, which salts are essentially insoluble in the reaction medium, the treatment being carried out by adding base until a pH value of about 2.8 is obtained, separating the precipitating product consisting mainly of a 3-nitrophthalic acid mono-salt, subsequently precipitating, by the addition of further base, a product consisting principally of a 4-nitrophthalic acid salt, and finally converting the resulting nitrophthalic acid salts separately into the corresponding free acids, and optionally purifying these. The 3- and 4-nitrophthalic acid can be obtained by the process according to the invention in a simple manner in an isomer-free form and in good to very good yields.

摘要： A process for joining components made of metal, in particular aluminum and aluminum alloys, is such that a thermally-curable (hardenable) adhesive is deposited between the close-fitting surfaces of the components that are to be joined, and one of the outer surfaces neighboring the said close-fitting surface of one of the components is radiated with infra-red radiation in order to cure the adhesive. At least the outer surface to be radiated is provided with a pattern that roughens that surface. By reducing the reflectivity of the roughened surface the capacity to absorb infra-red radiation is increased. A preferred application for the process is in the adhesive bonding of shaped parts, especially body sheet in automobile manufacture.
