Abstract

PURPOSE: To obtain the titled compound useful as an intermediate for various chemical raw materials inexpensively in high selectively and in high yield, by reacting monoepoxide of a 1,3-diene with water in the presence of a reaction accelerator consisting of a combination of a metal iodide and a strong acid.
CONSTITUTION: A monoepoxide of 1,3-diene shown by the formula I (R1WR4 are H, or 1W4C hydrocarbon residue) is reacted with water in the presence of both an iodide of metal selected from a group consisting of alkali metals, alkaline earth metals, and zinc (preferably iodide of Na, K, Mg, Ca, and Zn) and an acid (preferably ion exchange resin having sulfuric acid, hydrochloric acid, or sulfonic acid group) selected from the group consisting of sulfuric acid, hydrochloric acid, hydrobromic acid, hydroiodic acid, phosphoric acid, and sulfonic acid at a temperature 0W150°C, to give a 2-butent-1,4-diol shown by the formula II. In the amount of the reaction accelerator, 0.5W1.5g equivalent iodide of alkali metal and 0.05W 0.6g equivalent acid are used based on 1mol monoepoxide.
