The present invention provides an improved process for preparing DTEA HCl from decene and cysteamine HCl by using a catalyst, solvent and a co-solvent to aid the reaction and provide low temperature stabilization of the resulting product solution.

Process for preparing DTEA HCl

A method for treating in an industrial water treatment system for at least two of metal corrosion inhibition, scale inhibition, suspended matter dispersion, biocide efficacy, or biofilm removal/biofilm dispersion is taught by the use of at least one compound which is a salt derived from a thioamine or an oxyamine and an acid.

Multiple uses of amine salts for industrial water treatment

The present invention provides for a slow release composition, preferably as a tablet, for industrial water systems, under an alkaline pH or high water hardness, using as an active ingredient a multifunctional amine of Formula (I) and a hydrophilic polymer, and other components such as a compression agent, in one composition as a biocide, biostat, biodispersant, deposit penetrant aid, organic deposit remover, detergent, surfactant, antifoam, scale inhibitor, scale remover, and a corrosion inhibitor. The composition is used in multiple water cycles, can remove, disperse or inhibit fouling. The active ingredient(s) of the composition is released over a long time, up to 6 months.
