Versuchsvorschrift

The recrystallized N-(2-hydroxyethyl)-N,N,N-trimethylammonium bromide (55.86 grams, 0.30 moles) was placed in a 100 ml flask fitted with a magnetic stirrer and a pressure equalizing addition funnel. Water (29 ml) was added to make a 50% solution and the solution was stirred vigorously while 48.5 grams (0.30 moles) of bromine was added dropwise from the addition funnel. The tribromide fell out of solution as a dark red oil. The product was separated from the aqueous layer by decantation and the residual water removed by warming to 50° C. at aspirator pressure for fifteen minutes. The yield of N-(2-hydroxyethyl)-N,N,N-trimethylammonium tribromide was 103.16 grams. Analysis: %Brtot =67.63 (exp), 69.71 (theo); %Brox =44.10 (exp), 46.41 (theo).
