| titleOfInvention |
A kind of preparation method of lactide |
| abstract |
The invention provides a preparation method of lactide. The preparation method of lactide is to carry out cyclization reaction of gaseous lactide under the catalysis of titanium-containing molecular sieve to obtain product lactide. The preparation method provided by the invention has the advantages of simple process, high conversion rate of lactate and high selectivity of lactide. |
