Description

200936595 IX. OBJECTS OF THE INVENTION [Technical Fields of the Invention] The present invention relates to a method for producing a polycarbonate containing a plant-derived component, which is used as a raw material, and a method The antioxidant can reduce the purification method of the anhydrous sugar alcohol characterized by the formation of a peroxide. 0 [Prior Art] Today, there is concern about global warming caused by the depletion of petroleum resources or the carbon dioxide generated by the waste gas treatment, and the anhydrous sorbitol dianhydrohexitol (isomannose) Alcohol, isoidido and iso-dian sorbitan) are plant-derived diols derived from plant-derived raw materials of mannitol, iditol and sorbitol, and can be used as raw materials for pharmaceuticals, etc. in recent years. Polymers are particularly renewable resources used in the manufacture of polyesters and polycarbonates (similar to natural resources such as petroleum or stone carbon, such as forest resources, biomass, wind, small scale The resources such as hydraulics and the like that have their own regenerative ability are being discussed enthusiastically (for example, Patent Documents 1 to 4, etc.). Further, it is known that the above-mentioned anhydrous sugar alcohols are decomposed and denatured depending on storage conditions, and various stability improvements have been discussed. For example, Patent Document 5 discloses that a specific reducing agent such as sodium borohydride or a stabilizer improving agent such as an antioxidant is added at a specific time in the anhydrous sugar alcohol producing step, and then stored at 40 ° C to obtain stability. Improvement. On the other hand, the inventors of the present invention have reviewed the production of the polymer of the above-mentioned anhydrous sugar alcohol as the raw material 200936595, and found that the stability improving agent exemplified in Patent Document 5 described above may contain a metal component, which may cause a decrease in polymerization rate. Further, the present inventors have found that after the purified anhydrous sugar alcohols are purified, the impurities are removed and used directly in the melt polycondensation reaction. The quality of the obtained or obtained polycarbonate is good, but when the purified anhydrous sugar alcohol is added to the air environment without being added to the stability improving agent or the like, it is decomposed and deteriorated after the number & When the deteriorated anhydrous sugar alcohol is supplied to the polycondensation reaction, the reactivity or the quality of the polymer is lowered. In industrial production, when the raw materials are delivered from overseas, they will pass through high-temperature areas or sea areas, or sometimes from the purchase of raw materials to the use of the materials for a considerable number of days. However, it is not preferable from the viewpoint of cost when the polymer raw material is continuously stored during the period from the production, transportation, and storage to the reaction, for example, under an inert environment. Further, in the case where a substance having a bad influence on the quality of the polymer is contained in the raw material, a production step in which the raw material to be purchased is supplied to the polycondensation reaction immediately after pure deuteration is disadvantageous in terms of cost. Therefore, when it is desired to obtain a good quality polymer from an anhydrous sugar alcohol, it is not necessary to use a stabilizer containing a metal component which adversely affects the quality of the polymer, and it is expected that the anhydrous sugar alcohol which can be stably stored at a relatively high temperature for a long period of time is expected. A method for the stabilization of a type, and a method for producing a polycarbonate from a stabilized anhydrous sugar alcohol by this method. Further, the present inventors have considered that a high-purity anhydrous sugar alcohol having a small amount of peroxide can be obtained under the purification step of the final stage -8-200936595 in the production of anhydrous sugar alcohol, and only this can be obtained by stabilization. As a better preserved and good polymer raw material, no known technique for the amount of peroxide in the anhydrous sugar alcohol or its reduction method has been found.
