CAS: 164118-71-2 | ERUCAMIDOPROPYL HYDROXYSULTAINE

Erucamide hydroxysulfobetaine, also known as erucamide hydroxysulfobetaine, erucamide hydroxysulfobetaine, erucamide hydroxysulfobetaine, etc., English name: 1-Propanaminium, N- (2-hydroxyethyl)-N,N-dimethyl-3-[[(13Z)-1-oxo-13-docosenyl]amino]-, chloride

CAS:581089-19-2, molecular formula: C29N2O2+.Cl-, molecular weight: 443.7755

The properties of erucamide hydroxysulfobetaine are as follows:

1. Erucamide hydroxysulfobetaine has excellent anti-calcium properties, with a tolerance to Ca2+ of more than 8 g.L-1.

2. Erucamide hydroxysulfobetaine has the ability to significantly reduce the interfacial tension of oil and water. When combined with other surfactants, it has a good synergistic effect. The EHSB40 multi-surface activation complex system can achieve ultra-low interfacial tension of the order of 10-4 ~ 10-3mN/m with crude oil of various reservoir conditions.

3. The sand-carrying performance test of erucamide hydroxysultaine shows that this system can achieve good sand-carrying effect when the sand ratio is 30% or even 40%.

4. The gel breaking performance test of erucamide hydroxysulfobetaine shows that the system can break the gel in the presence of formation water or crude oil, and there is no residue after the system breaks the gel.

5. In the ethanol aqueous solution of erucamide hydroxysultaine, this product can form worm-like micelles and has excellent viscosity-increasing properties.

6. Erucamide hydroxysulfobetaine is a biodegradable viscoelastic surfactant.

Erucamide hydroxysultaine can be used for the following purposes: Since erucamide hydroxysultaine has good viscosity and can form a gel, it can be used in fracturing fluids and acid liquid thickeners. It can be used as an ideal surfactant for oil displacement in chemical composite flooding, which can increase oil recovery by more than 15%.

Recommended application ratio and method of erucamide hydroxysulfobetaine: The recommended addition amount is 1.0-4.0%. The product is first dissolved in an acidic solution such as hydrochloric acid, and then diluted before use.
