Abstract
Emulsifier particles and methods for making and using same. The emulsifier particles can include an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate, an alkali metal salt or an alkaline earth metal salt of a modified tall oil, or a blend of an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate and an alkali metal salt or an alkaline earth metal salt of a modified tall oil. The emulsifier particles can have a BET specific surface area of about 0.3 m2/g to about 1 m2/g. The method for making the emulsifier particles can include reducing a size of an emulsifier solid via a mechanical attrition process to produce the emulsifier particles.
Claims16
A method for making emulsifier particles, the method comprising
- distilling a liquid composition to produce a molten emulsifier, wherein the liquid composition comprises (1) an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate, (2) an alkali metal salt or an alkaline earth metal salt of a modified tall oil, or (3) a blend of an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate and an alkali metal salt or an alkaline earth metal salt of a modified tall oil;
- cooling the molten emulsifier to produce an emulsifier solid;
- and
- reducing a size of an emulsifier solid via a mechanical attrition process to produce emulsifier particles having:
- a Brunauer/Emmett/Teller (BET) specific surface area of about 0.3 m2/g to about 1 m2/g,
- a BET pore volume of at least 0.001 cm3/g to about 0.005 cm3/g,
- a BET average pore width of about 50 angstroms to about 200 angstroms,
- a bulk density of about 0.3 g/cm3to about 0.6 g/cm3, and
- a weight average particle size of about 5 μm to less than 80 μm.
