Abstract
Disclosed is a method of preparing fatty acid alkyl ester sulfonate using coffee oil. The fatty acid alkyl ester sulfonate prepared using the coffee-derived oil has superior cleaning capacity compared to commercially available alkylbenzene sulfonate (LAS). In addition, a detergent composition containing fatty acid alkyl ester sulfonate prepared using coffee-derived oil exhibits cleaning capacity equal to or higher than that of a detergent containing fatty acid alkyl ester sulfonate prepared using palm oil and can be used as an alternative to palm oil.
Claims11
A method of preparing fatty acid alkyl ester sulfonate, the method comprising:
- a first step of adding a short-chain alcohol and a basic catalyst to an oil extracted from coffee beans or coffee grounds, followed by transesterification to prepare unsaturated fatty acid alkyl ester;
- a second step of adding hydrogen to the unsaturated fatty acid alkyl ester, followed by complete or partial hydrogenation to prepare saturated fatty acid alkyl ester;
- and
- a third step of mixing the saturated fatty acid alkyl ester with a sulfonating agent to synthesize the fatty acid alkyl ester sulfonate.
