Rate constants of non-catalyzed hydrolysis of 3-acetyl-1,3-diphenyltriazene (I) and 3-(N-methylcarbamoyl)-1,3-diphenyltriazene (II) have been measured in the presence of salts (ammonium chloride, potassium chloride, lithium chloride, sodium chloride and bromide, ammonium sulphate, potassium sulphate, lithium sulphate, sodium sulphate and zinc sulphate) within broad concentration ranges. Temperature dependence of the hydrolysis of the substrates studied has been measured in the presence of lithium sulphate within temperature range 20° to 55 °C. The results obtained have been interpreted by mechanisms of hydrolysis of the studied substances.

In the reciprocal salt pair Li2, K2, Cl2, SO4, and water, at 25 °C there are large areas in which potassium sulphate and potassium lithium sulphate (KLiSO4) are separately in equilibrium with solution. Two incongruent invariant points exist. At one of these the composition of the solution is 0.917 mole fraction chloride, 0.437 mole fraction lithium, and 19.4 moles of water per total mole of salt, the equilibrium solid phases being potassium chloride, potassium sulphate, and the double salt. At the second, the composition of the solution is 0.967 mole fraction chloride, 0.870 mole fraction lithium, and 13.8 moles of water per mole of salt, the solid phases being potassium chloride, double salt, and lithium sulphate monohydrate. One congruent invariant point exists, at which the composition of the solution is 1.00 mole fraction chloride, 0.960 mole fraction lithium, and 9.6 moles of water per mole of salt, the solid phases being lithium sulphate monohydrate, lithium chloride monohydrate, and potassium chloride.In the reciprocal salt pair Li2, Na2, Cl2, SO4, and water, at 25 °C there is an incongruent invariant point at which the composition of the solution is 0.873 mole fraction chloride, 0.668 mole fraction lithium, and 15.1 moles water per total mole of salt, the solid phases being sodium chloride, solid solution of sodium and lithium sulphates, and lithium sulphate monohydrate. A congruent invariant point exists, at which the composition of the solution is practically entirely lithium chloride, the solid phases present being lithium chloride monohydrate, lithium sulphate monohydrate, and sodium chloride.

New Phase

Previously obtained conductivity and viscosity results for the system (Li,K)2SO4 with less than 3 mole% K2SO4 show bad agreement with the phase diagram given in the literature. From conductivity, viscosity and differential thermal analysis we have constructed a new phase diagram for these concentrations.

Our study aims at improving the nutritional quality of eggplant fruits through application of organic fertilization. The study was conducted in Bingerville (located in the south of Côte d'Ivoire and west of Abidjan city), from April to August 2019. The work consisted in assessing, in a randomized complete block design, the effects of five manures on the biochemical parameters of Kalenda eggplant (Solanum melongena L.) fruits. The manures studied were T1: chicken manure, T2: chicken manure + plantain peel compost, T3: chicken manure + plantain peel potash, T4: plantain peel compost, T0: no fertilizer, T5 (positive control): NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4). The results showed that fiber, protein, lipid, sodium and iron contents were not influenced by the different treatments. However, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost), T3 (chicken manure + plantain peel potash) and T2 (chicken manure + plantain peel compost) induced the highest carbohydrate and energy content of fruits. With respect to phosphorus and potassium, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost) and T3 (chicken manure + plantain peel potash) had higher phosphorus values than those of other fertilizers T2 (chicken manure + plantain peel compost), T1 (chicken manure) with an average of 27; 26.58 and 25.491 mg per 100 g FM, respectively. Plants grown on the sites fertilized with chemical treatment T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) produced the fruits richest in potassium with an average equal to 255.16 mg per 100 g FM, followed by treatment T3 (chicken manure + plantain peel potash) (245.5 mg/100g FM). For magnesium and calcium, treatments T3 (chicken manure + plantain peel potash) and T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) were characterized by the lowest contents, thus reflecting an antagonism between potassium and these minerals. From this study, it appears that plantain peel applied as an organic fertilizer on eggplant is a source of potassium, phosphorus, carbohydrates and energy for a good nutritional balance of the body.
