GUANYLHYDRAZINE BICARBONATE - Nature

Open Data Verified Data

White fine crystalline powder. Soft, practically insoluble in water, insoluble in alcohol and other acids. Heating is not stable, when more than 45 degrees Celsius is gradually decomposed, melting point of 170~172 degrees Celsius. If it is heated slowly, it can be melted. When it is heated to 171~173 ° C in an oil bath, it will be completely decomposed. The decomposition products are soluble in water and can be decomposed by other acids, free aminoguanidine is formed and dissolved in water.

GUANYLHYDRAZINE BICARBONATE - Preparation Method

Open Data Verified Data

there are the following process routes.

  1. with lime nitrogen, hydrazine hydrate, ammonium bicarbonate as the main raw material. The distilled water is added to the lime nitrogen, the temperature is kept at 45~50 ℃ for 6 hours, the waste residue is filtered off to obtain the calcium cyanamide solution, and then dilute sulfuric acid is added to adjust the pH value to 6~7, after cooling to room temperature and filtering, the cyanamide solution is obtained, in which 5% hydrazine hydrate is added, and the temperature is kept at 50 ° C. For 4 hours, then ammonium bicarbonate is added, and the crystal is precipitated, filter dry is aminoguanidine bicarbonate crude. Then add acetic acid to dissolve the crude product, add oxalic acid, filter off calcium oxalate, adjust the pH value of the solution to 8~9 with ammonia water, and add a small amount of EDTA disodium salt, the filtered filtrate is reacted with the filtered ammonium bicarbonate solution, placed, crystallized, filtered, washed with distilled water and ethanol respectively, and finally dried by filtration to obtain a finished product.
  2. aminoguanidine bicarbonate can also be obtained by reacting cyanamide with hydrazine sulfate and then adding an aqueous solution of sodium bicarbonate to the reaction.

this product can be used as a synthetic raw material for medicine, pesticide, dye, photographic agent, foaming agent and explosive.
production method 1. made from lime nitrogen, hydrazine hydrate, ammonium bicarbonate or sodium bicarbonate. First, distilled water is added to lime nitrogen, kept at 45-50 ℃ for 6 hours, waste residue is filtered to obtain cyanamide (calcium) solution, then dilute sulfuric acid is added to cyanamide (calcium) solution to pH = 6-7, cooled to room temperature, and calcium sulfate is filtered to obtain cyanamide solution. Then 5% hydrazine hydrate is added to cyanamide solution, kept at 50 ℃ for 4 hours, then ammonium bicarbonate is added, and crystals are precipitated, filter to dry is crude aminoguanidine bicarbonate. Dissolve the crude with acetic acid, add oxalic acid, filter to remove calcium oxalate, adjust the solution to pH = 8-9 with ammonia water, add a little EDTA disodium, filter to be clear, then add filtered ammonium bicarbonate solution, place, crystallize, filter to dry, wash with distilled water and ethanol respectively, and filter to dry to obtain the finished product. 2. Condensation reaction of methyl isothiourea sulfate, hydrazine hydrate and sodium bicarbonate: dissolve methyl isothiourea sulfate in water, add hydrazine hydrate dropwise at room temperature, continue to stir for 1.5h after addition, and filter. The filtrate is concentrated to 2/5 of the original volume under reduced pressure, then the pH is adjusted to 5 with acetic acid, cooled to below 30 ℃, saturated bicarbonate solution is added under stirring, the material is released after stirring for 2 hours, cooled overnight, filtered, the filter cake is first washed with water, then washed with ethanol, and dried at 50 ℃ to obtain aminoganidine bicarbonate. Yield 85%-90%. 3. Use cyanamide and hydrazine sulfate to react, and then add sodium bicarbonate aqueous solution to react, and aminoguanidine bicarbonate can also be prepared.
