Abstract: 
This research investigates the monoethanolamine pulping with a concentration of 50% and alkali sulphite with 18% alkalinity for making pulp from corn stalks. The combination of sodium hydroxide and sodium sulphite in ratio of 70: 30 as a measure of alkali sulphite and water and monoethanolamine with a ratio of 50: 50 were selected as control treatments. The amount of deficiency was eliminated during all processes due to the fact that it was not minor and could not be weighed. Furthermore, the pulping conditions were chosen as variables: the process of alkali and soda sulphite was combined; time was 30: 60: 90 minutes at the three levels and the temperature was 125, 145 and 165 degrees at the three levels; and the ratio of the baking fluid to the raw material (1 to 4) remained constant. The paper pulp produced with monovalent and 50% had the lowest amount of total efficiency (36. 12) and kappa number (17. 93). In alkaline sulphite treatment, it was observed that decreasing the temperature and increasing the time as variable factors, results in a decrease in the total return value and the kappa number likewise increases, so that the highest burst index (6. 78) is related to baking with a temperature of 125 degrees and the total time would be 60 minutes. The results of this study show that monoethanolamine/water (50: 50) can be successfully used to make paper from corn stalks, and the characteristics of the pulp of manufactured paper, especially in terms of mechanical strength and kappa number, when mixed with water; and that it is superior to the process of alkali sulphite both as a combination and by itself.
