Abstract
The disclosure provides a preparation process of an allyl alcohol polyether with a low potassium and sodium content, comprising the following steps: reacting allyl alcohol with a mixture of epoxypropane and oxacyclopropane to prepare an allyl alcohol oligomer crude product with a molecular weight of 150-1500; reducing the total content of potassium and sodium ions in the allyl alcohol oligomer crude product prepared in step S1 to 2 ppm or less through a cation exchange resin; and reacting the allyl alcohol oligomer product treated in step S2 with the mixture of epoxypropane and oxacyclopropane to prepare allyl alcohol high-molecular-weight polyether with a molecular weight of 2000-5000. According to the present disclosure, the total content of potassium and sodium ions in the product is reduced to 2 ppm or less, and the product has a good double bond protection rate.
