Ammonium taurate preparation method

The invention relates to a method for synthesizing a taurine precursor-ammonium taurate by directly using ethylene and sulfur trioxide as initial raw materials. In the method, ethylene and sulfur trioxide are reacted in a solvent to prepare a cyclic intermediate, and under the action of a catalyst and a ligand, the cyclic intermediate is subjected to a reaction with ammonia to form ammonium taurate. Compared with the preparation method of the taurine precursor in the existing ethylene oxide methods, the method has the advantages of low raw material cost, high product selectivity, and mild reaction conditions.

Method for preparing taurine and co-producing bicarbonate

The invention discloses a method for preparing taurine and co-producing bicarbonate. The method comprises the step of leading carbon dioxide gas or adding a carbon dioxide water solution to an amino ethyl sulfonate water solution of alkali metal or ammonium to regulate a pH value so as to obtain the taurine and the bicarbonate. The method can replace an existing taurine preparation method of using sulfuric acid or sulfur dioxide to regulate the pH value, meanwhile can treat boiler exhaust gas, turns the carbon dioxide in the exhaust gas into wealth, co-produces the bicarbonate and is a safe, environmentally-friendly and energy-saving method for producing the taurine and co-producing the bicarbonate.
