The synthesis method of the invention is as follows: first, 5-amino-2-(p-aminophenyl)- benzoxazole and aliphatic diacid are respectively recrystallized; NMP is distilled; solubilizer is dried; second, in an atmosphere of nitrogen, after Py and NMP are mixed evenly and added to a sealed reactor, the solubilizer is added into the reactor, followed by the 5-amino-2-(p-aminophenyl)- benzoxazole, then the mixture in the reactor is stirred; second, in an atmosphere of nitrogen, the mixture in the second step is stirred and heated to 50-150 DEG C, then the aliphatic diacid is added, followed by TPP for condensation; fourth, after methanol is poured into the reactor, the sediment is separated out from the mixture, filtered, washed and dried, so the semi-aromatic polyamide containing oxazole ring is obtained.

本发明的合成方法如下：一、分别重结晶5-氨基-2-苯并唑与脂肪族二酸；蒸馏NMP；干燥增溶剂；二、在氮气气氛下，Py与NMP混匀后加入密封的反应器中，再加入增溶剂，然后加入5-氨基-2-苯并唑，搅拌；三、在氮气气氛下，将步骤二的混合液搅拌并升温至50℃～150℃后加入脂肪族二酸，再加入TPP后缩聚；四、再倾入甲醇析出沉淀，过滤，清洗沉淀，再干燥；即得到含唑环半芳香聚酰胺。

The preparation of the membrane is that the phthalazine polyether-sulfone-ketone polymer is mixed with chloroform, Ethanol or butanol according to certain quality proportion; after the magnetic stirring, the evenly mixed casting solution is obtained, filtered and carried out with vacuum deaeration; The casting solution is scraped into membrane of certain thickness on the non-woven fabric by adopting the scraper; the membrane is standed for 24 hours in the air of certain humidity and temperature to obtain the plate ultrafiltration membrane of phthalazine polyether-sulfone-ketone.

本发明公开了属于高分子膜分离技术领域的一种二氮杂萘聚醚砜酮类聚合物平板超滤膜的制备方法，所述膜的制备方法为：用二氮杂萘聚醚砜酮类聚合物与氯仿、无水乙醇或正丁醇按照一定的质量比混合，磁力搅拌后得到混合均匀的铸膜液，过滤并真空脱泡；将铸膜液采用刮刀在无纺布上刮制成一定厚度的膜，该膜在一定湿度和温度的空气中静置24h后即得到二氮杂萘聚醚砜酮类平板超滤膜。

Take the 10~12ml single-valve capacity as the example, with flings turns the head to separate evenly, 36.000rpm 60 the hour, turns the head with the angle type to separate 45, OOOrpm 36 the hour, the former including adds the deceleration to use in common 130,000,000 revolution of actuation department lives, the latter must use 100,000,000 revolution of actuation department lives, this was 100 ~ 20,000,000,000 transfers to at that time the supercentrifuge total life looked, without doubt each time tests the expense to be excessively high, in addition the CsCl amount used are many, price expensive and so on factors, causes this kind of separation purification work to become the very expensive experiment.

以10~12ml单管容量为例，用甩平转头分离，36.000rpm 60小时，用角式转头分离45，OOOrpm 36小时，前者包括加减速在内共用去1.3亿转驱动部寿命，后者也要用去1亿转驱动部寿命，这对当时超速离心机总寿命为100~200亿转来看，无疑每次实验费用过高，加上CsCl用量多、价格贵等因素，使这类分离纯化工作成为非常昂贵的实验。
