YieldReaction ConditionsOperation in experiment
88.1% 10051] These examples demonstrate the cyclic use of mother liquor in the preparation of taurine. Using the same one-liter autoclave, the starting materials given in the table were reacted at 120°C. for 18 hours. Afierwards, the solution is cooled to 10° C. to crystallize taurine and ammonium sulfate, which are filtered off and washed with a solution saturated with ammonium sulfate. The mother liquor ischarged with ammonium sulfite monohydrate and then adjusted to pH 7.2 with aqueous ammonium hydroxide. AES is then charged and pH rechecked and if necessary readjusted to 7.2 with ammonium hydroxide or dilute sulfuric acid. The results are shown in the following table.10052] The solid filtrate, comprised of taurine and ammonium sulfate, from each batch, is combined and stirred as a suspension in water to dissolve ammonium sulfate. After filtration, crude taurine is washed with water and recrystallized from deionized water. Yield: 379.7 g (81.0percent).10053] An additional 15.2 g (3.2percent) of taurine is recovered from the mother liquor afier recrystallization and separation of ammonium sulfate.

YieldReaction ConditionsOperation in experiment
85% With ammonium sulfate; sulfuric acid; ammonium sulfite monohydrate; In water; at 110℃; for 24h;pH 6.2 - 7.2;Autoclave; 10047] Into a one-liter autoclave equipped with a stirrer were charged 251 g of ammonium sulfite monohydrate, 40 g of ammonium sulfate, 15.3 g of MEA, and 300 mE of water. Afier the pH of the solution was adjusted to 7.2 with 6 N sulfuric acid, 106.7 g of AES was added. Afier the reaction was carried out at 110° C. under autogenous pressure for 24 hours, the pH was found to be 6.2.10048] HPEC analysis showed that the solution contains 79 g of taurine (85percent theoretical yield), 1.4 g ofunchangedAES (1.3percent), and 22.2 g of MEA.
