    Abstract: 1,139,919. Urea derivatives. BADISCHE ANILIN- & SODA-FABRIK A.G. 16 May, 1966 [20 May, 1965], No. 21615/66. Heading C2C. [Also in Division A5] The invention relates to compounds of the formula in which R 1 is a methyl, methoxyl or 1-methyl- 2-propinyl radical and the group R-NH and is derived from 2-amino-[3,2,1]-octanes. Compounds claimed per se are 1-(2-bicyclo-[3,2,1]- octyl) - 3,3 - dimethylurea; 1 - (2 - bicyolo- [3,2,1] - octyl) - 3 - methyl - 3 - (1 1 methyl- 2 1 - propinyl) - urea; 1 - (2 - bicyclo - [3,2,1]- octyl) - 3 - methyl - 3 - methoxyurea. The compounds may be prepared by reacting a 2- hydroxymethyl bicyclo -[2,2,1]-heptane with a nitrile and hydrolysing the resulting bicyclo- [32,1]-octyl amide-2 and reacting the resulting 2-amino bicyclo-[3,2,1]-octane with either (a) N-dimethyl, N-methyl-N-methoxyl or N- methyl - N - (1 - methyl - 2 - propinyl) - carbamyl halides or carbamic esters, or with (b) phosgene to the corresponding isocyanates or carbamyl chlorides followed by further reaction with dimethylamine, methyl methoxylamine or methyl-(1-methyl-2-propinyl)-amine.

    Abstract: Polyamides may be prepared by heating mixtures of and with dicarboxylic acids or esters or chlorides thereof. Acids specified are adipic, sebacic, decane dicarboxylic, suberic, terephthalic, cyclohexane dicarboxylic and pyridine dicarboxylic acids. Where the acid itself is used this may be in the form of its salt with the amine. The reaction may be carried out in the absence of oxygen at superatmospheric pressure, water being removed in the later stages by an inert gas stream, e.g. N2, or by application of a subatmospheric pressure. Where the acid ester is used the reaction may be in 2 stages. In the first stage the diamine and ester may be heated, optionally in a solvent, e.g. an alcohol or aromatic hydrocarbon to form a precondensate. In the second stage the precondensate solution may be heated to distil off the solvent and complete the polymerization. Heating in this stage may be above 200 DEG C. and under an inert atmosphere of subatmospheric pressure. Where the acid chloride is used the reaction may be carried out at a water/non-aqueous solvent interface, the diamine being dissolved in the former and the acid halide in the latter. Non-aqueous solvents specified are CCl4 and toluene. The reaction mixture may include a lactam, e.g. caprolactam, a chain terminator, e.g. a monocarboxylic acid or monoamine or an amide forming derivative of either, a thermal stabilizer, photostabilizer, optical brightener, filler and/or lubricant. The products may be used to make injection mouldings, sheets, rods, bristles, filaments and threads.
