Structure
Properties
Appearance (1), brown semi-solid or flowing liquid; (2), solid.
Solubility insoluble in water.
Stability stable.
Risk Solid form: flammable material; irritation, moderate irritation to skin, eye, respiratory. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.
GHS label: 
Liquid form: flammable material; irritation, moderate irritation to skin, eye. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.
GHS label:
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent antirust, anticorrosive, lubricating, emulsifying, solubilizing, dispersing abilities. Good anti-rust effect to ferrous metals. To acid medium, has a good neutralization and replacement abilities. Flow-type product has a good oil solubility, and it is easy to use.
Synthesis
Currently, sulfonation reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfonates.
Generally, distillate oil (Typical: lubricating oil distillate) and sulfur trioxide react through reactor, then barium hydroxide neutralizes, finally obtain product.
US patent 8,921,588 (Process for preparing sulfates and/or sulfonates in a micro-reaction system) presents a synthetic process.
