| abstract |
The invention relates to a process for the production of croton lactone, which is used as a plant growth substance (for wheat, maize and cotton) and plasticizer and represents a valuable intermediate of organic fine synthesis. In order to increase the yield and raise the purity of the target product, as a chemical reagent, thiourea is used in an amount of 2-10 wt%; the reaction mass is treated at a temperature of 20-80C. |
