| titleOfInvention | The preparation method of sucralose |
| abstract | The application provides a method for preparing sucralose, comprising: making the chlorination reaction liquid for preparing sucralose-6 ester, the first liquid caustic soda and the first recycled water enter into a neutralization reaction rectification tower by stages, and after evaporation After the neutralization reaction is carried out under the conditions, the solvent mixture is extracted from the column top of the neutralization reaction rectification; the chlorination reaction neutralization solution is extracted from the column bottom of the neutralization reaction rectification; the chlorination reaction neutralization solution and the second liquid caustic soda are extracted. Enter the hydrolysis reaction rectification tower with the second reuse water in sections, carry out alkaline hydrolysis reaction under evaporation conditions, extract the waste aqueous solution from the tower top of the hydrolysis reaction rectification tower, and extract three from the bottom of the hydrolysis reaction rectification tower. The aqueous sucralose solution; the aqueous sucralose solution is adjusted to neutrality, followed by extraction, oxidation, and back-extraction for purification; and a crystallization step. The present application is an efficient, green and continuous sucralose preparation process, which has extremely high application value and practicability. |
