    摘要： Process for preparing primary amines from aldehydes by mixing an aldehyde with a diluent, where in the case of an alcohol or of water as diluent the mixing temperature is at most 5.degree. C. to prevent the formation of the hemiacetal or the aldehyde hydrate, and bringing the mixture into contact with a mixture of ammonia, hydrogen and hydrogenation catalyst, whereby the formation of an imine is prevented, at temperatures of from 60.degree. to 180.degree. C. and pressures of from 20 to 60 bar, at least 15 mol of ammonia being used per mol of aldehyde group, and also an apparatus for carrying out the process.

    摘要： Amine salts of 3-phenyl-6-halo-4-hydroxypyridazines of the formula: ##STR1## in which X is a chlorine or bromine atom, R.sub.1 is an alkyl group containing up to 14 carbon atoms, which group may be substituted by a hydroxy group, an alkoxy group containing up to 10 carbon atoms, cyano group, amino group or lower mono- or lower dialkylamino group, an alkenyl group containing up to 6 carbon atoms or a cycloalkyl group containing 5, 6 or 7 carbon atoms, and R.sub.2 and R.sub.3 have the same meaning as R.sub.1 or each is a hydrogen atom, or R.sub.1 and R.sub.2 together with the nitrogen atom of the amine form a 5- or 6-membered heterocyclic group which may also contain oxygen and which may be mono- or di- substituted by alkyl, and herbicidal compositions containing them.
