More Information
Summary:The invention discloses a preparation method of chemical products and particularly relates to a preparation method ofleucine, which comprises the steps: adding a hydrolysis assistant, and hydrolyzing hairs by using a multi-step hydrolysis method, so as to improve the hydrolysis yield of the leucine; introducing hydrolysis liquid after the hydrolysis into a concentration tank, concentrating by using steam at 110-120 DEG C, neutralizing by sulfuric acid for the first time, carrying out aminolysis, adding a decolorizer for decoloration, and neutralizing by ammonia water for the second time so as to obtain a product by using a refine process. The hair utilization rate is high, the production efficiency is high, the dried product is put in storage after being detected and packed. The method has the benefits that the technology is mature, the raw material utilization rate is high, the product yield is high, and the operation is convenient, so that the method is suitable for continuous large-scale production.
