Embodiment Construction

[0015] Concrete preparation steps are as follows:

[0016] The first step of ring opening: add 85kg (1mol) of propenyl alcohol and 600ml (0.007mol) of boron trifluoride ether solution into the batching kettle, stir well and preheat the reaction solution to 50℃~55℃, then add epoxy chlorine Propane 120kg (1.4mol) controls the flow rate, gradually heats up the temperature, collects the front fraction when the temperature of the material in the kettle rises to 130°C, and sets the temperature of the temperature controller at 160°C, and turns off the power when the temperature of the material rises to 142°C At this time, the reaction temperature will continue to rise to about 146°C, indicating that the condensation ring-opening reaction is successful. When the temperature of the material in the kettle drops to 120°C, 190kg of distillate is collected, and the refractive index of the distillate is: n 25 D 1.4625±0.0005.

Abstract

This invention provides an allyl glycidyl ether industrialized preparation method. It uses Boron trifluoride diethyl ether comoles compound as catalyst, propylene alcohol and epichlorohydrin as raw material, pass through the condensation ring-opening reactions generate 1-chloro-2-hydroxy-3- allyloxy propane, then under alkaline conditions through close-loop to obtain allyl glycidyl ether; the product yield rate is 78%, the content of 98%.

Description

Technical field: [0001] The present invention relates to the preparation method of allyl glycidyl ether. Background technique: [0002] The chemical name of allyl glycidyl ether is 1-allyloxy-2,3-propylene oxide, which is a kind of active monomer containing unsaturated double bonds and epoxy groups, mainly used in epoxy resins , adhesives and fibers, coating reactive intermediates, and can also be used as electronic coating silicone intermediates. At present, the organosilicon surfactant widely used in daily fine chemical industry, its good water solubility and surface activity is obtained by grafting allyl glycidyl ether on the hydrogen-silicon bond. [0003] There are not many ways to prepare allyl glycidyl ether. Because the product contains two active groups at the same time, it is difficult to synthesize. At present, aliphatic glycidyl ether is usually synthesized. There are one-step and two-step methods for its synthesis. two kinds. [0004] One-step method: refers ...
