Product Details
Polyisobutylene Succinic Anhydride (PIBSA)
High-Activity Intermediate for Lubricant Dispersants & Industrial Emulsifiers
Polyisobutylene Succinic Anhydride, commonly known as PIBSA, is a critical chemical intermediate in the lubricant and explosives industries. At Chemost, our PIBSA is synthesized using high-activity polyisobutylene (HR-PIB), ensuring a product with low residual impurities and high reactivity.
Manufacturing Excellence: The Thermal Adduct Process
Our PIBSA (Molecular Weight approx 1000) is produced through a clean, chlorine-free thermal process. Unlike older methods, our direct thermal reaction minimizes corrosive by-products.
Our Synthesis Protocol:
- Pre-activation: HR-PIB is pre-heated at 180°C for one hour to ensure uniformity.
- Thermal Reaction: Maleic Anhydride is introduced at temperatures exceeding 200°C under atmospheric pressure (1 atm).
- Refinement: Through a controlled, gradual reduction of temperature and pressure, we strip unreacted monomers.
- Result: A high-purity succinic anhydride with a low color scale and excellent solubility in base oils.
Primary Industrial Applications
1. Intermediate for Ashless Dispersants (PIBSI)
PIBSA is the foundational "building block" for manufacturing Polyisobutylene Succinimide (PIBSI). By reacting PIBSA with various polyamines, manufacturers produce ashless dispersants essential for engine oil cleanliness, sludge prevention, and soot suspension.
2. High-Stability Mining Emulsifiers
In the explosives industry, PIBSA serves as a high-performance emulsifier for Emulsion Explosives.
Superior Stability: It creates a robust interface between the oxidizer salt solution and the fuel phase.
Safety & Efficiency: Its chemical structure ensures the emulsion remains stable during transport and storage in harsh mining environments.

Frequently Asked Questions (FAQ)
Q: What is the advantage of your thermal PIBSA over the chlorine-process PIBSA?
A: Thermal PIBSA is virtually chlorine-free. This significantly reduces the risk of corrosion in the final lubricant formulation and is more environmentally friendly during the manufacturing of dispersants.
Q: Can the saponification value be customized for specific emulsifier needs?
A: Yes. As a manufacturer, we can adjust the reaction parameters to reach specific saponification targets required for different mining or industrial applications.
Q: How should PIBSA be stored for long-term stability?
A: It should be stored in a dry, cool, and well-ventilated warehouse. While stable, we recommend keeping it in sealed containers to prevent moisture absorption, which could lead to the hydrolysis of the anhydride group.
