The invention relates to the use of at least one 1-alkyl-3-alkyl-pyridinium halide, in particular 1-alkyl-3-methyl-pyridinium bromide, as an additive in bromine-generating electrochemical cells, such as zinc/bromine cells. Processes for preparing 1-alkyl-3-methyl-pyridinium bromide and concentrated aqueous solutions comprising same for use as additives in the aforementioned cells, are also disclosed.

Processes for preparing 1-alkyl-3-alkyl-pyridinium bromide and uses thereof as additives in electrochemical cells

Flame retardant aqueous dispersions or suspensions comprising tris(tribromophenoxy)-s-triazine (TTBT) or tetrabromobisphenol A bis(2,3-dibromopropyl ether) (TBBPE) or a mixture thereof and one or more nonionic or anionic surface active agent(s) and/or wetting agent(s) used in textile are described. The flame retardants exhibit high compatibility with textile materials and are stable in aqueous solutions.
