| titleOfInvention | A kind of production technology of anhydrous acetone acetal |
| abstract | The invention discloses a production process of anhydrous acetone acetal. The production process comprises the following steps: using glycerol and acetone as raw materials, using an acidic ion exchange resin as a catalyst, and performing a reaction; the reaction process continuously removes moisture in a reaction system; After the end, the reaction system is subjected to post-treatment to obtain the acetone acetal product. During the preparation of acetal acetal, water will be generated, which will not only reduce the single-pass yield of acetal acetal in the reaction process, but also cause the hydrolysis of acetal acetal in the process of separating and purifying the acetal acetal product, further reducing the yield of the product. The process of the invention removes the moisture generated by the reaction in time, the conversion rate of the acetal acetal in the reaction process is high, and it is also beneficial to the purification process of the subsequent product. |
