摘要:Relating to the technical field of biological buffer reagent synthesis, provided is a preparation process for a sulfonic acid-containing compound and a slat thereof, comprising the following preparation steps: reacting a compound 1 with a compound 2 to obtain a compound 3; reacting the compound 3 with an M-containing reagent to obtain a crude product of an M-containing slat corresponding to a sulfonic acid-containing compound 4; and after acidification reaction, obtaining a crude product of the sulfonic acid-containing compound 4. Finally, the high-pure sulfonic acid-containing compound 4 and the salt thereof are obtained by performing purification process on the crude products of the sulfonic acid-containing compound 4 and a salt thereof. Raw materials used in the preparation method are low in cost and simple in operation, the obtained product is high in purity and suitable for industrial production, and the obtained product can satisfy requirements of the field of biological buffers on purity, impurity content, and cost.
