There is disclosed a process for producing alkali taurinate from alkali isethionate, alkali ditaurinate, or alkali tritaurinate by adding excess ammonia and at least of equal molar amount of an alkali hydroxide to a solution comprised of alkali ditaurinate, alkali tritaurinate, or their mixture and subjecting the solution to an ammonolysis to yield a solution comprised of alkali taurinate.

Disclosed are novel phosphono-phosphate and anionic group containing polymer compositions that have targeted uses with divalent cations and surfaces having divalent cations. These compounds can be used to deliver anionic character to surfaces such as calcium hydroxyapatite.

Methods and machinery are described for combining methane with sulfur trioxide to make MSA, in a system that sustains optimal concentrations of reactants in the main reactor for high yields, efficiency, and profitability. Rather than simply making MSA and then removing it, this design uses a “continuous loop system” with: (i) a “rich acid” stream containing a high concentration of MSA, mixed with sulfuric acid, which will emerge from the main reactor, and (ii) a “reduced acid” stream containing a low concentration of MSA (still mixed with sulfuric acid), from an extractor unit (such as a distillation unit) which removes some but not all of the MSA from the “rich acid”. Additional subassemblies are described which enable the main reactor to work efficiently, at a sustained high flow-through capacity. This system also can be scaled up or down, for any daily MSA production rate.

There is disclosed a process for producing taurine in a molar yield of at least 80% from alkali isethionate, alkali ditaurinate, or alkali tritaurinate by adding excess ammonia and at least of equal molar amount of an alkali hydroxide to a solution comprised of alkali ditaurinate, alkali tritaurinate, or their mixture and subjecting the solution to an ammonolysis to yield a solution comprised of alkali taurinate.
