After 4h of reaction, gas phase detection shows that the reaction is almost finished, and the content of each component is 0.5 percent of raw material methyl allyl chloride, 91 percent of acetic acid methyl allyl alcohol ester, 6.5 percent of methyl allyl alcohol and 0.8 percent of methyl allyl ether.
Example 5
Adding a reaction product obtained in any one of the embodiments 1-4 into a reaction kettle, carrying out layered separation to obtain a crude product, slowly dropwise adding a sodium hydroxide aqueous solution with the mass percent of 5%, heating and refluxing for 2 hours, comprehensively hydrolyzing an ester (the obtained formic acid or the methyl allyl acetate in the embodiments) to obtain a methyl allyl alcohol crude product, standing and layering, drying and rectifying the upper layer to obtain the methyl allyl alcohol product, wherein the yield is over 91%. Drying and rectifying to obtain a product methallyl alcohol, and performing nuclear magnetic detection, wherein the detection result is as follows:
1H NMR:δ1.30(s,3H),2.0(s,1H),4.8(m,1H),5.21(m,1H),5.35(m,1H)5.81(d, 1H); the product obtained in the application is proved to be the target product.
The examples show that the methallyl alcohol prepared by the method has the advantages of high yield, few side reactions, simple reaction steps and low raw material cost.
