Piece-form materials which comprise 5-100% by mass calcium formate and 95-0% by mass additives and have particle sizes of 0.2-5 mm can be prepared from finely crystalline calcium formate and the additives by compression and, if necessary, subsequent comminution and/or fractionation to set the particle size.

Piece-form calcium formate

The present invention relates to rubber mixtures consisting of at least one rubber and a specific proportion of a distillation residue from industrial trimethylolpropane production and the use of the rubber mixtures for the production of vulcanisates, especially for the production of highly reinforced, abrasion-resistant mouldings, particularly preferably for the production of tyres exhibiting low rolling resistance and high abrasion resistance.

Rubber mixtures containing trimethylopropane distillation residues

The present invention provides a process for preparing 2-(methylthio)-5-(trifluoromethyl)-1,3,4-thiadiazole. The process includes the steps of reacting methyldithiocarbazinate with a molar excess of trifluoroacetic acid and recovering the excess trifluoroacetic acid.

Process for preparing 2-(methylthio)-5-(trifluoromethyl)

The present invention provides a process for making thiadiazole sulfones. The present process is used to make 2-(methylsulfonyl)-5-(trifluoromethyl)-1,3,4-thiadiazole. 2-(Methylsulfonyl)-5-(trifluoromethyl)-1,3,4-thiadiazole is made using catalytic oxidation in the presence of a suitable oxidizing agent. The catalyst used for the oxidation reaction is glacial acetic acid.
