| titleOfInvention | A kind of method utilizing micro-reaction system synthesizing polyethylene butyral |
| abstract | The present invention relates to a kind of method utilizing micro-reaction system synthesizing polyethylene butyral.Described micro-reaction system is sequentially connected is formed by microreactor, tubular reactor and collection kettle；Cavity disperse characteristic plate or minim channel are set inside described microreactor；On described cavity disperse characteristic plate, sieve aperture or groove are set.Raw material A and raw material B are joined in microreactor by the present invention, and hemiacetal reaction reaction of formation liquid C occurs；Described raw material A is the mixed solution of polyvinyl alcohol and hutanal, and raw material B is HCl/water solution；Reaction liquid C enters and occurs aldolisation to generate the suspension D of polyvinyl butyral resin in tubular reactor；Suspension D enters and collects kettle.The present invention utilizes the characteristic of microreactor strengthening reaction to complete overwhelming majority hemiacetal reaction before PVB forms precipitation, it is ensured that the uniformity of product acetal degree and the lot stability of product, improves product quality. |
