Introduction | heavy alkylbenzene sulfonate is heavy alkylbenzene after sulfonation, neutralization synthesis of anti-rust additives, it has good emulsifying properties. |
Application | The sodium heavy alkylbenzene sulfonate can be combined with other additives to prepare emulsified cutting oil, wire cutting working fluid, hydraulic transmission fluid, internal combustion engine coolant and other emulsified oil. It is similar to the performance of petroleum sodium sulfonate, so it can be used instead of petroleum sodium Sulfonate in the production of some products, especially in emulsified oil. |
purpose | is used as emulsifier to prepare emulsified oil for fully mechanized coal mining machinery. for the preparation of rust preventive oil, emulsified oil, can also be used as cosolvent |
production method | C14 ~ 18 alkylbenzenesulfonic acid is added dropwise to the aqueous solution of sodium hydroxide and processed to obtain a finished product. See the preparation method of calcium alkylbenzene sulfonate for details. |
