Sulfamic Acid For Industrial Scenarios - China

Sulfamic Acid (Amidosulfonic Acid) – Versatile Solid Strong Acid for Industrial Scenarios

Basic Product Information

• Synonyms: Sulfamide acid, Amidosulfonic acid

• Chemical Formula: NH₂SO₃H

• Molecular Weight: 97.094

• CAS No: 5329-14-6

• EINECS No: 226-218-8

Product Overview

Sulfamic acid is a high-performance solid strong acid widely used as a core industrial raw material.

It stands out for its excellent acidity, low corrosivity, and convenient logistics (replace liquid sulfuric acid with easier packaging storage or transportation), making it a cost-effective choice across multiple sectors.

Physical & Chemical Properties

• Appearance: White rhombic flake crystals (commercial products are supplied as white powder)

• Density: 2.126 g/cm³

• Melting Point: 205℃ (starts decomposing at 209℃; fully decomposes at 260℃, releasing SO₂, SO₃, N₂, water and trace substances)

• Water Solubility: 146.8g/L (20℃)

• Stability: Non-hygroscopic and stable at room temperature when stored in dry, water-free environments

Key Advantages (Aqueous Solution)

• Equivalent strong acidity to hydrochloric acid/sulfuric acid (earns the name "solid sulfuric acid")

• Non-volatile, odorless, and low toxicity to humans (note: avoid prolonged skin contact & eye exposure)

• Can replace liquid sulfuric acid, with far more convenient packaging, storage and transportation

Industrial Applications

1 - Sweetener Production: Core raw material (0.7 tons of sulfamic acid consumed per ton of sweetener)

2 - Metal Cleaning: High-efficiency ionic cleaner for removing surface oxides; lower corrosivity than other inorganic acids (ideal for boiler cleaning & system maintenance)

3 - Pulp & Paper Processing: Bleaching/whitening agent for fibers, wood & paper; removes nitrite from tobacco

4 - Multi-functional Auxiliary: Serves as catalyst, disinfectant and flame retardant

5 - Dyes & Pigments Manufacturing: Key raw material

6 - Electroplating: Process additive

7 - Analytical Chemistry: Primary standard reagent for acid-base titration
