| titleOfInvention | The method of continuous production poly butylene succinate |
| abstract | The invention discloses a kind of preparation method of the overall industrial chain of poly butylene succinate, on the one hand the quality of uncontrollable raw material in the prior art is overcome, on the other hand the problem of by-product small molecule is more, yield is relatively low in the prior art are overcome, so as to effectively reduce the production cost of poly butylene succinate.The present invention general reaction route beļ¼Normal butane is gone out with C-4-fraction rectifying, liquid phase cis-butenedioic anhydride is produced with normal butane, succinic anhydride is produced by raw material of liquid phase cis-butenedioic anhydride, with succinic anhydride, 1,4 butanediols carry out ring-opening polymerisation with catalyst in nitrogen atmosphere, then polycondensation reaction is carried out under vacuum, that is, obtains target product poly butylene succinate. |
