Abstract
PURPOSE: An alkali metal salt of taurine is made to react with glycolonitrile to form N-cyanomethyltaurine, which is hydrolyzed to give title compound useful as a builder in high yield inexpensively.
CONSTITUTION: After taurine is converted into the alkali salt with a caustic alkali, glycolonitrile is made to react with the salt usually at 10W60°C for 30 minW3hr to prepare N-cyanomethyltaurine. The resulting reaction mixture is hydrolyzed using l.0Wl.5 moles, per mole of glycolonitrile, of a caustic alkali to give title compound.
