How to make organophilic clay

Organoclay | Organophilic Clay CP-2 also named amine treated Bentonite.

In diesel oil based fluids,organophilic clay viscosifier CP-2 are used to increase carrying capacity and suspension properties, providing support for weight materials and improved cutting removal. Organophilic bentonite also aids in filter-cake formation and filtration control.

How to make organophilic clay

Selection of the appropriate organic modifier quaternary amine salt to achieve the desired pro-organic properties. Temperature, time and agitation speed to ensure effective ion exchange.

To minimize impurities in the product, it is important to ensure that the washing process is adequate. Also control the temperature to prevent decomposition of the organic modifier. The temperature should never be too high.

We give an example of a complete preparation process. 100 parts of ethanol, 4 parts of raw mineral clay (montmorillonite), 0.3 parts of dimethyl silicone oil, 0.1 parts of dodecyl fatty acid. Add 100% ethanol to the reactor. Add 0.3 parts of dimethyl silicone oil and 0.1 parts of dodecyl fatty acid respectively under stirring state, dissolve well.

Then slowly add 4 parts of montmorillonite powder and continue to mix with stirring. The reactor was filled with nitrogen for 10 minutes and then sealed. The temperature was raised to 40-45°C under airtight condition and the reaction was carried out for 2.5 hours. After cooling to room temperature, the clay dispersion system was removed from the reaction kettle and drained.

The organophilic clay was dried and pulverized at 50°C to produce the organophilic clay. The above procedure allows for the preparation of clays with organophilic properties, which have good stability and suspension properties in applications such as oil-based drilling fluids.

How to make organophilic clay? The preparation of organobentonite involves a process of material preparation, heating and mixing, and extrusion and drying. Cation exchange and intercalation of organic molecules make the organobentonite hydrophobic. Currently, the dominant preparation processes are dry and wet.
