Method and system for continuous kettle type industrial production of crude acetal product

The invention discloses a method and a system for continuous kettle type industrial production of a crude acetal product, and belongs to the technical field of chemical production. A feeding mode of simultaneously, preferably and continuously adding corresponding reaction materials in the same proportion is adopted, and particularly, the temperature is controlled, so that the whole reaction process is continuously carried out; compared with a feeding mode of dropwise adding an acrolein-weak acid mixture into diethyl methylphosphite in the prior art that, the feeding mode of the invention realizes the continuous kettle type reaction process for preparing the crude acetal product, so the problems existing in the intermittent kettle type production process are effectively solved; and the production efficiency of the crude acetal product is effectively improved, the production cost is reduced, and meanwhile, large-scale industrial production is facilitated. 本发明公开了一种缩醛粗品的连续釜式工业化生产方法及系统，属于化工生产技术领域。本发明所述方法通过采用同时，优选同
