| titleOfInvention | Device and method for industrially preparing L-lactide |
| abstract | The invention relates to a device for industrially preparing L-lactide, which comprises a multistage dehydration prepolymerization unit, a pre-cracking unit and a cracking cyclization unit which are connected in sequence. The invention also provides a method for industrially preparing the L-lactide, which comprises the steps of multistage dehydration prepolymerization, precracking and cracking cyclization which are sequentially carried out. The device and the method provided by the invention can realize continuous production of the L-lactide, have the advantages of short reaction time, low required temperature, high production efficiency and high product purity, and are easy for subsequent separation and purification. |
