Applications:
• Tetrabutyl ammonium hydroxide as Catalysts in the electrochemical synthesis of Adiponitrile; Catalysts in the polymerization of silicone rubber and other silicone products; As phase transfer catalysts in organic synthesis chemistry.
• TBAH aqueous solution as Molecular sieve template.
• Tetrabutyl ammonium hydroxide in water as Adjusting agents in surfactant products.
• TBAH as Cleaning agents for the electronic industry (such as chip cleaning agents).
• TBAOH also used as Polarographic reagents and pH regulators in the field of analytical chemistry.
Reference Crystalline Temperature for TBAH:
TBAH Assay | 10% | 25% | 40% | 55% |
Temperature | ~5℃ | ~25℃ | ~16℃ | ~8℃ |
(Note: When temperature lower than mentioned, TBAH solution will form crystalline hydrate solid in the liquid. This will not affect the quality. After heating, the crystalline solid TBAH will be back to transparent liquid again. For different assay TBAH, crystalline temperature is different.)
