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.

The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.
