Dodecylene succinic acid CAS:29658-97-7

What is Dodecylene Succinic Acid CMET T746?

CMET T746 is an ashless oil‑soluble rust inhibitor with dodecylene succinic acid molecular structure developed by FansChem, CAS No.: 29658‑97‑7. It is light yellow to brown viscous liquid, featuring stable acid value, low odor and low toxicity. The additive can form firm adsorption oil film on metal surfaces to block corrosive media, delivering anti‑rust protection for aluminum and copper alloys, while it is not suitable for lead and cast iron materials. It also acts as an excellent co‑solvent for benzotriazole (BTA), widely compounded with other rust additives, detergents and dispersants to prepare engine lubricants, industrial circulating oils and anti‑rust greases. Standard packaging adopts 50kg / 180kg plastic drums, which shall be stored in cool, dry and well‑ventilated warehouses.

Features of Dodecylene Succinic Acid CMET T746

• Excellent oil solubility & stable acid value: Fully miscible with various mineral and synthetic base oils; acid index remains stable during long‑term storage and formula blending, no sharp fluctuation of finished oil acid value.

• Dense protective oil film for multi‑metal anti‑corrosion: Adsorbs tightly on metal substrates to form compact hydrophobic film, effectively suppress rust of copper, aluminum and ferrous metals; note weak protection performance for lead and cast iron.

• Good universal additive compatibility: Can be perfectly matched with other rust inhibitors, detergents, dispersants and triazole metal passivators without turbidity or precipitation.

• Special co‑solvent function for BTA: Strong solubilizing capacity for benzotriazole solid powder, solves the dissolution difficulty of BTA in oil formulas and improves system stability.

• Low odor & low toxicity raw material: Mild smell and low toxicity characteristic, friendly for workshop operating environment and finished oil application scenarios.

• Wide compound formulation flexibility: Suitable for single use or mixed compounding with multiple anti‑rust additives to upgrade comprehensive salt fog and damp‑heat resistance.

Functions of Dodecylene Succinic Acid CMET T746

• Multi‑metal anti‑rust protection: Forms compact hydrophobic adsorption oil‑film on metal surface, isolates corrosive media and provides rust protection for steel, copper and aluminum alloys.

• BTA solubilization: Serves as efficient co‑solvent for benzotriazole, improving dissolving performance of solid BTA in oil‑based lubricant formulations.

• Formula compatibility stabilizer: Compatible with detergents, dispersants and other auxiliary additives, avoiding turbidity and precipitation in compound additive systems.
