Abstract:

This article is devoted to development of an environmentally safe technology for production of an explosive substance – starch nitrate. The aim of the development was to create the technology for starch nitrate production, which reduces the man-made burden on the environment, due to the absence of acidic wastes discharged into the environment, and also ensures the chemical stability of starch nitrate. This is achieved by starch nitration with highly concentrated nitric acid without adding sulfuric acid. To work out this process in laboratory conditions, nitration of starch was carried out with

Abstract:

It was studied the Processes of ensuring chemical stability (stabilization) of starch nitrate obtained by nitration of starch by two ways: nitric acid and nitric-sulfuric acid mixture. It has been confirmed that, in the first case, starch nitrate has much higher stability due to the absence of low-stable sulfuric acid esters. It is shown that to ensure it in this case, 10 minutes of washing of starch nitrate in 0.19 m3/kg of hot water (95 °С) is sufficient. It was established that in the case of nitration with nitric acid, an increase in the nitrogen content in starch nitrate, which characteri

Production of potato starch produces wastewaters with high concentrations of COD, nitrogen and phosphorus. The best known and most economical solution for the nearly full elimination of these substances is the two-stage anaerobic-aerobic treatment. The anaerobic pretreatment must only go so far as to maintain enough COD for biological nitrogen and phosphorus elimination in the aerobic stage. To optimize this process, several tests have been carried out on nitrification/denitrification by means of the intermediate product nitrite.

Abstract:

This study aimed to evaluate the growth and yield of two potato genotypes (S) due to three sources of nitrogen (G) fertilizer on medium plains. The study was arranged in a two-factor, randomized block design factorial and was repeated three times. The first factor is the source of N fertilizer, consisting of three levels: S1 = ZA ((NH4)2SO4), S2 = urea (CO(NH2)2), and S3 = ammonium nitrate (NH4NO3). The second factor was potato genotype, consisting of two levels G1 = MS 13 genotype and G2 = At 4 genotype. The data obtained were analyzed by F test at 5% level (ANOVA) to determine the effect of

This study examined the potential economic returns of using four different sources of nitrogen on `calabaza' pumpkins, a low moisture variety consumed as starch by many foreign nationals. Yields were 12.4, 12.6, 8.2 and 9.5 kg/plant for ammonium nitrate, sodium nitrate, ammonium sulfate and urea, respectively. Assuming 1989 farm gate prices in Alabama and other appropriate cost for vaious inputs used, the estimated return at $0.30/lb of pumpkin was $10,003, $10,115, $6,105 and $7,371/acre for different sources of nitrogen, respectively.
