A practical and scalable synthesis of ultra-long chain fatty acids avoiding column purification.

Fatty acids of vegetable and animal origin are an important renewable feedstock for the chemical industry. Their application has increased multifold during the last two decades. While there are many ways to synthesize fatty acids, the chemical synthesis route offers more advantages in terms of versatility and targeted synthesis. Though remarkable achievements have been made in the field of fatty acid synthesis, it is still in the preliminary stage of optimization. In this paper, we wish to report a more practical & scalable approach for the synthesis of fatty acids with carbon atoms ranging from 20 to 45.
