Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical production, specifically a stirring mechanism for small-scale production of sodium nitroprusside. Background Technology
[0002] Sodium nitroprusside, with the chemical formula C5H4FeN6Na2O3 and a molecular weight of 297.95, is a compound. It is a bright red, transparent, crystalline powder, readily soluble in water, with a brown liquid state. It is unstable and easily decomposes upon standing or exposure to light, converting ferric ions (Fe3+) to ferrous ions (Fe2+), turning the liquid blue. Due to its rapid action and quick disappearance of precipitates, it is a commonly used drug for treating hypertensive emergencies and acute left ventricular failure. In the production and preparation of sodium nitroprusside, a solid-liquid mixture is usually used, requiring stirring during the reaction to ensure complete reaction.
[0003] Traditional stirring mechanisms typically only stir solutions, using the solution to mix solid powders. This can lead to incomplete diffusion of the solid powders, resulting in insufficient mixing and a reduced reaction rate. To address these issues, this invention proposes a stirring mechanism for the small-scale production of sodium nitroprusside. Utility Model Content
