After stirring for 15 minutes, newly ground anhydrous K2CO3 (1.87 g, 11.56 mmol) was added to this solution.
One mL sample solution and 1 mL of saturated K2CO3 were also placed into the outer section of the same cell, and the lid was immediately closed.
The reaction between 2-aminobenzothiazole and anhydrous K2CO3, ethyl chloroformate, and ethanol provided ethyl (1,3-benzothiazol-2-yl) carbamate through the reaction with hydrazine hydrate and ethanol to produce N-(5-fuorobenzothiazol-2-yl) hydrazine carboxamide.
A mixture of 2-mercaptobenzothiazole (1.0 mmol) in dry acetone (20 ml), anhydrous K2CO3 (1.1 mmol), and the compound-1 (1.0 mmol) obtained in the previous step was stirred at room temperature for 15-16 h.
Four groups of samples {A (Table 1), B (Table 2), C (Table 3), and D (Table 4)} were stored in four saturated solution conditions (LiCl RH15%, Mg[Cl.sub.2] RH30%, K2CO3 RH 44%, NaCl RH 75%) for two months.
The clinical evidence indicated that the supplementation of buffering agents, bicarbonates and carbonates including sodium bicarbonate (NaHCO3), magnesium oxide (MgO), potassium bicarbonate (KHCO3) and potassium carbonate (K2CO3) are of significant value in increasing the ruminal pH of SARA affected animals (Erdman, 1988).
N-(2-Hydroxypropyl)methacrylamide (HPMA) was synthesized as described previously using K2CO3 [8] as a base.
The sorbent was activated chemically by utilizing 0.1M HCl and 0.1M K2CO3. A close muffle furnace was used for thermal treatment of the sorbent.
Determination of amino acids in plasma: Plasma (0.5 mL) was deproteinized with 0.5 ml of 1.5 mM HClO4, followed by addition of 0.25 ml of 2 M K2CO3. The neutralized extract was analyzed for amino acids using high-performance liquid chromatography.
Compound 1 was dissolved in acetone (HPLC grade) and then K2CO3 was added.The reaction mixture was stirred for 30 minutes and then added tert-butyl bromoacetate.
