Substituted benzylimidazolium salts of the formula ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are identical or different and are each hydrogen, C.sub.1 -C.sub.4 -alkyl or halogen, R.sup.4 is alkyl of 8 to 14 carbon atoms or benzyl which is unsubstituted or substituted by halogen or alkyl, R.sup.5 is hydrogen, alkyl of 1 to 8 carbon atoms, phenyl or benzyl, R.sup.6 is alkyl of 1 to 4 carbon atoms or halogen, R.sup.7 is alkyl of 1 to 4 carbon atoms or halogen and X is an anion of an acid, in particular of a hydrohalic acid, and microbicides containing these compounds.

Microbiocidal substituted benzylimidazolium salts

1-Hydroxymethylimidazoles which are unsubstituted or alkyl-substituted in the 2-position, their manufacture and their use as chemical intermediates, e.g. for other imidazole derivatives or for the drug cimetidine.

Process for preparing 4-methyl-5[(2-aminoethyl)thiomethyl)]-imidazole

Process for producing 1-hydroxymethylimidazoles

Manufacture of 4-nitroimidazoles by nitrating imidazoles with nitric acid in the presence of urea while at the same time removing water from the mixture by distillation. The compounds which can be manufactured by the process of the invention are catalysts for polymerization reactions and condensation reactions, especially for reactions with epoxides, the aldol condensation, the manufacture of polyurethanes, condensation reactions with malonic esters or acetoacetic esters and intermediates for the manufacture of dyes, textile auxiliaries and insecticides.
