| titleOfInvention | One kind synthesis 1,4：The method of 3,6 pairs of dewatering hexitol methyl ethers |
| abstract | The invention discloses one kind synthesis 1,4：The method of 3,6 pairs of dewatering hexitol methyl ethers.With 1,4：3,6 pairs of dewatering hexitols are initiation material, and Isosorbide-5-Nitrae is generated as methylating reagent, in the presence of acidic etherified effect using methyl ether compound：3,6 pairs of dewatering hexitol methyl ethers.Wherein, Isosorbide-5-Nitrae：3,6 pairs of dewatering hexitol methyl ethers are selected from the mono-, di- methyl ether of isobide, isomannite and different iditol, preferably isosorbide, dimethyl ether, and the total recovery of isobide methyl ether is up to more than 80%.The present invention uses environmentally friendly acidic catalyst, high catalytic efficiency, avoids the generation of a large amount of halide salt accessory substances in traditional etherification method, and the corrosion problems caused by highly basic, there is provided a kind of new, efficient Isosorbide-5-Nitrae：3,6 pairs of dewatering hexitol methyl ether syntheti c routes, and realize environmental friendly catalysis etherification reaction. |
