In the complex landscape of modern chemical manufacturing, certain high-purity compounds serve as the silent backbone for countless consumer goods. Among these, the industrial application of 67 48 1, widely recognized as Sodium Bicarbonate, stands out due to its versatile chemical properties and safety profile. From stabilizing pH levels in pharmaceutical formulations to acting as a primary leavening agent in the global food industry, this compound is indispensable for maintaining product quality and consistency.
The global demand for 67 48 1 has seen steady growth, driven by an increasing emphasis on food safety and the expansion of the pharmaceutical sector. As manufacturers shift toward sustainable and non-toxic additives, the role of this white, odorless crystalline solid becomes even more critical. Its ability to decompose into carbon dioxide, water, and sodium carbonate makes it a preferred choice for processes requiring controlled gas release or mild alkalinity.
Understanding the technical specifications of 67 48 1 is essential for procurement managers and formulation chemists alike. By adhering to strict standards such as GB1887-2007 and securing SGS certification, producers ensure that the heavy metal content remains negligible and the purity stays within the 99%-100.5% range, meeting the rigorous demands of international food-grade and pharmaceutical-grade markets.
Technical Specifications of 67 48 1
The technical profile of 67 48 1 is defined by its extreme purity and precise chemical composition. With a molecular formula of NaHCO3 and a molecular weight of 84.01, it presents as a white, odorless crystalline solid. For industrial use, the content typically ranges between 99% and 100.5%, ensuring that reactions in food processing or pharmaceutical synthesis are predictable and free from unwanted side effects caused by impurities.
Critical purity markers for 67 48 1 include strict limits on heavy metals, with lead (Pb) capped at 0.0005% and arsenic (As) at 0.0001%. These rigorous thresholds are vital for food-grade certifications, as they prevent contamination in the human food chain. Additionally, a pH value of approximately 8.5 confirms its nature as the mildest of all sodium alkalis, making it safe for various sensitive applications.
Chemical Properties and Stability of 67 48 1
One of the most significant characteristics of 67 48 1 is its solubility and thermal behavior. It is completely soluble in water, allowing for easy integration into liquid solutions, though it remains only slightly soluble in ethanol. This distinction is often used in laboratory settings to identify the substance and ensure that no contaminants are present in the batch.
Thermal stability is another core attribute, as 67 48 1 begins to decompose at approximately 60°C. During this decomposition process, the compound releases carbon dioxide gas, which is the fundamental mechanism behind its use as a leavening agent in baking and as a blowing agent in the production of rubber and plastics foam.
Moreover, the specific gravity of 2.159 provides a consistent density for packaging and transportation. Because it is an amphoteric compound, it can react with both acids and bases, providing a unique buffering capacity that is highly valued in effluent water treatment and flue gas treatment to neutralize harmful pollutants.
Industrial Production and Synthesis of 67 48 1
The synthesis of 67 48 1 typically involves the reaction of purified sodium carbonate or sodium hydroxide solutions with carbon dioxide. By bubbling CO2 through these solutions, the bicarbonate precipitates out of the liquid. This process relies on the fact that sodium bicarbonate is less soluble than sodium carbonate, allowing for efficient separation and purification.
To ensure the high quality of 67 48 1, the carbon dioxide used must be highly purified to prevent the introduction of organic contaminants. Once the precipitation is complete, the crystalline solids are filtered, washed, and dried. This meticulous process ensures the final product adheres to the GB1887-2007 standard, providing a reliable raw material for global industries.
Modern production facilities, such as those in China, have scaled this process to achieve massive productivity, often reaching 500 MT per month. This scalability ensures that the supply of 67 48 1 remains stable even during peak demand periods in the food and pharmaceutical sectors, preventing price volatility in the global market.
Multi-Sector Applications of 67 48 1
The utility of 67 48 1 spans a vast array of industries, making it one of the most versatile inorganic chemicals available. In the food sector, it is the gold standard for baking soda, used to create airy textures in cakes and breads. In the pharmaceutical realm, its mild alkalinity makes it an ideal ingredient for antacids and certain dialysis treatments.
Beyond consumption, 67 48 1 plays a vital role in environmental protection. It is used extensively in flue gas treatment to scrub acidic gases from industrial emissions and in water treatment to adjust pH levels. Furthermore, its flame-retardant properties make it a key component in dry chemical fire extinguishers and explosion suppression systems.

FAQS
The primary difference lies in the purity levels and the strictness of the contaminant limits. Food grade 67 48 1 must adhere to stringent standards like GB1887-2007, ensuring that heavy metals such as lead and arsenic are kept at extremely low levels (0.0005% and 0.0001% respectively) to ensure human safety. Industrial grade may have slightly higher impurity thresholds as it is used for applications like flue gas treatment or fire suppression where human ingestion is not a factor.
Sodium bicarbonate is sensitive to moisture and heat. To maintain its quality, 67 48 1 should be stored in a cool, dry, and well-ventilated warehouse, away from strong acids and incompatible chemicals. Using the provided 25kg P.P woven bags or 1000kg jumbo bags helps protect the crystalline powder from humidity, which prevents caking and ensures the material remains free-flowing for industrial use.
Yes, it is widely used in pharmaceuticals due to its mild alkalinity and high safety profile. It serves as an essential component in antacids to neutralize stomach acid and is used in hemodialysis to balance pH levels in the blood. However, for medical use, it is imperative to source a Pharma Grade version of 67 48 1 that meets specific pharmacopeia standards for endotoxin and impurity levels.
When stored under optimal conditions—dry and cool—67 48 1 has a very long shelf life, typically lasting several years. However, if exposed to high humidity or moisture, it may clump or "cake," which doesn't necessarily change its chemical potency but makes it difficult to dose accurately in industrial processes. Regular inventory rotation is recommended to ensure peak performance.
Verification can be done through a combination of COA (Certificate of Analysis) review and independent third-party testing. Check that the shipment is accompanied by an SGS certification and that the specifications match the GB1887-2007 standard.
