Isopropyl Xanthic Acid (Isopropyl Xanthate)
CAS Number: 140-93-2
Isopropyl Xanthic Acid (also known as isopropyl xanthate free acid) is used as an intermediate in xanthate synthesis and as a direct collector in acidic flotation circuits where the free acid form is more effective than sodium or potassium salts. It is particularly useful in acid circuit copper flotation and in the flotation of oxide ores following acid conditioning, where the pH is too low for effective use of xanthate salt collectors.
Technical Specifications
| pH (neat) | 2-4 |
| appearance | Yellow oily liquid |
| purity (%) | ≥90 |
| acid value (mg KOH/g) | 480-510 |
Applications
- Acid circuit copper and zinc sulfide flotation
- Collector in acid-conditioned oxide ore flotation
- Intermediate for xanthate salt synthesis
- Flotation of copper minerals at low pH
- Combined use with dithiophosphates in acid circuits
Key Features
- Effective collector in low-pH flotation where xanthate salts are unstable
- Free acid form provides different adsorption kinetics from salt forms
- Suitable for integration into acid-base flotation sequential circuits
- Liquid form allows convenient metering in automated dosing systems
