Usage

Description

N,N'-ethane-1,2-diylbishexadecan-1-amide, also known as Ethylene bis-palmitamide, is a synthetic compound with a unique structure that consists of two palmitamide groups connected by an ethylene bridge. This structure endows it with specific properties that make it suitable for various applications.

Uses

Used in the Oil Industry:
N,N'-ethane-1,2-diylbishexadecan-1-amide is used as a fluidity improver for crude oil. Its application reason is that it can enhance the flow properties of crude oil, making it easier to transport and process. This is particularly useful in cold environments or when dealing with heavy crude oils that tend to become more viscous.
In the context of the provided materials, Ethylene bis-palmitamide is specifically used in the preparation and evaluation of acetal polyamine amide fluidity improvers for crude oil. This indicates that it plays a crucial role in the development of additives that can improve the efficiency of crude oil extraction and transportation.

A Novel Technique for the Preparation of Secondary Fatty Amides. III. Alkanolamides, Diamides and Aralkylamides

A low-temperature synthesis of fatty alkanolamides, fatty diamides and fatty aralkylamides directly from triglycerides and primary amines provides essentially quantitative yields of the various products.The reactions run to completion in 3-12 h at temperatures of 50-60 deg C, approximately 100 deg C lower than employed in present conventional practice.The amines are used in excess and serve as solvent, reagent and, perhaps, as catalyst.The amides were characterized by melting point and spectroscopic (infrared and nuclear magnetic resonance) methods.If the mixed amides produced from the various natural triglyceride mixtures of fats and oils are acceptable products, this synthetic method provides these products in satisfactory quality while conserving energy and avoiding the intermediate production of free fatty acids or their esters.
