1. The possible mechanism of the aminating electroreduction of pyruvic acid was obtained and we consider it as a CE reaction.

2. Using diethanolamine as aminating agent and glacial acetic acid as neutralizing agent, aminated epoxy acrylic cationic resin was prepared.

3. The results of mechanical analysis showed that the aminating treatment has little effect on the strength of CFs.

4. In aminating reaction of ethyl N-(2, 4-dimethylphenyl) formimidate some reagents are first used as catalyst and a better one is sifted out from many catalysts.

5. In this paper, the aminating electroreduction of pyruvic acid was studied by potentiodynamic method.

5. is a sentence dictionary, on which you can find good sentences for a large number of words.

6. It was shown that, conductivity firstly decreased , and then increased with aminating temperature increase.

7. The effects of polymerization process, functional monomers (AA/NMA) and aminating reaction on the properties of latex and hydrosol were studied.

8. The process of ring opening reaction is proved through analyzing aminating mechanism by IR and NMR.

9. The experiment results show that the weight increase of the aminating fiber rises with the decrease of fiber number, the increase of the reaction time and the reaction temperature.

10. Results show that the cross-section shape gets more and more circular with increasing of aminating degree and coagulation temperature.
