    Abstract: A composition comprises polypropylene and a carboxylic amide containing the grouping wherein R denotes a hydrogen atom or a hydrocarbon radical and the two carbon atoms in said grouping are not components of a carbonyl group, which carboxylic amide is not volatile at a temperature below 200 DEG C., and which is derived from a carboxylic acid having 2 to 30 carbon atoms and up to 6 carboxylic groups (with the exception of carboxylic amides) having the general formula R1-CONH-R4-NR2R3 wherein R1 denotes a saturated or unsaturated aliphatic monovalent hydrocarbon radical having 1 to 40 carbon atoms, R2 and R3 are each alkyl groups having 1 to 4 carbon atoms, and R4 is an alkylene radical having 1 to 10 carbon atoms. The compositions can be moulded or spun into filaments, threads, films and sheeting which can be dyed.

    Abstract: Aminoguanidine is produced by reducing nitroguanidine with sodium amalgam in aqueous solution or suspension at a temperature of from 0 DEG to 30 DEG C. and a pH of from 7.5 to 11. The pH value is controlled by adding a buffer substance, e.g. ammonium chloride or sulphate or boric acid, or an acid, e.g. sulphuric, hydrochloric, phosphoric or carbonic. The aminoguanidine may be precipitated as a sparingly soluble salt.

    Abstract: The partial hydrogenation of cycloaliphatic hydrocarbons having at least two olefinic double bonds is effected with hydrogen in the presence of metallic palladium and heavy metal ions (a heavy metal is one having a specific gravity above 5). Suitable starting materials contain 2-4 conjugated or non-conjugated double bonds in a C5-C12 ring which may be substituted by up to three C1-C4 alkyl groups or 1 or 2 double bonds in a C5-C12 ring and additionally 1 or 2 double bonds in a C2-C6 side chain or in a second C5-C8 alicyclic ring which may be fused to the first ring, e.g. cyclopentadiene, 1,3 - cyclohexadiene, 1,3,5-cycloheptatriene, 1,3- or 1,5-cyclooctadiene, cyclooctatetraene, cyclododecadiene, methyl-cyclopentadiene, dimethylcyclooctadiene, 1-vinyl - 1 - cyclohexene, 1 - vinyl - 4 - cyclohexene, limonene, 1,11-dicyclohexenyl, dicyclopentadiene, and bicyclo-[4,2,0]-octatriene-2,4,7. Metallic palladium is deposited on active charcoal, alumina, barium sulphate, calcium carbonate, pumice, silicates, or silica gel or a compound, e.g. oxide, hydroxide, carbonate or silicate, providing heavy metal ions. Suitable heavy metals are Cu, Ag, Zn, Cd, Hg, Tl, Pb, Sn, Sb, Bi, V, Zr and Fe; any salt other than catalyst poisons (e.g. cyanides, thiocyanates, sulphides and arsenites) may be used, the necessary amount varying according to the metal. In a preferred embodiment the supported palladium catalyst is boiled in an aqueous or alcoholic solution of the heavy metal salt for 5-120 minutes. Ammonia, amines, organic sulphides or ethers may also be present as catalyst deactivators. The process is preferably effected in an inert diluent, e.g. a saturated hydrocarbon, alcohol, ester or ketone at - 20 DEG to 150 DEG C.ALSO:A catalyst used in the partial hydrogenation of polyolefinic cyclic hydrocarbons comprises metallic palladium and ions of a heavy metal (i.e. one having a specific gravity above 5), particularly Cu, Ag, Zn, Cd, Hg, Tl, Pb, Sn, Sb, Bi, V, Zr, and Fe.

    Abstract: Compounds of the 1,3,4-thiadiazole, 1,3-benzothiazole, 1,3-benzoxazole and pyrimidine series, wherein is present once or twice a chlorine atom in an a -position to a ring nitrogen atom, are obtained by treating a corresponding mercapto compound with phosgene and accelerating the decomposition of the intermediate adduct which is formed by heating the reaction mixture and/or by the addition of an N-substituted amide of the formula wherein R1 denotes a hydrogen atom or an alkyl group with from 1 to 5 carbon atoms, R2 and R3 denote alkyl groups with from 1 to 4 carbon atoms or R1 and R2, when taken together, denote a tri- or tetra-methylene group, or R2 and R3, when taken together, denote an alkylene group with from 2 up to 8 carbon atoms. The reaction is usually carried out in an inert solvent, many of which are specified, having a boiling point between 35 DEG and 250 DEG C., and may be effected at normal or raised pressure. Besides the parent compounds of the specified heterocyclic series, derivatives thereof are mentioned containing methyl, phenyl, methoxyl and chloro groups as substituents. Substituted amides specified are dimethylformamide, N,N1 - dimethylacetamide, N,N1-dibutylformamide, N,N1-tetramethyleneformamide, N-methylpyrrolidone and N-butylpyrrolidone. Examples illustrate the preparation of 2-chloropyrimidine, 2-chloro-4-methylpyrimidine, 2 - chloro-4,6-dimethylpyrimidine, 2 - chlorobenzothiazole, 2 - chlorobenzoxazole and 2,5-dichloro-1,3,4-thiadiazole. The compounds obtained are intermediates in the production of dyes.
