Abstract
The invention relates to an industrial production method of glycerol formal, which comprises the following steps: adding glycerol, paraformaldehyde and cationic resin into a reaction kettle, heating to 90-110 DEG C, reacting for 1.5-3 hours, evaporating to remove the generated moisture after the reaction is finished, filtering to recover the cationic resin, and rectifying the product to obtain the glycerol formal, the conversion rate is high, the raw materials are cheap and easy to obtain, and the product yield reaches more than 95%. The proportion of the six-membered ring product is 70% or above, the overall production cost can be effectively reduced, the energy consumption is reduced, and meanwhile the production efficiency is improved.
