Usage And Synthesis

Uses

N,N-Bis(2-hydroxyethyl)dodecanamide is used in preparation method of water-absorbent resin for improving anti-caking performance.

Definition

ChEBI: N,N-bis(2-hydroxyethyl)dodecanamide is a fatty amide.

General Description

Off-white waxy solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

An alcohol and amide. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Fire Hazard

Flash point data for LAURIC ACID DIETHANOLAMIDE are unavailable, however, LAURIC ACID DIETHANOLAMIDE is probably combustible.

Flammability and Explosibility

Non flammable

Synthesis

111-82-0

111-42-2

120-40-1

Methyl laurate and diethanolamine were used as raw materials, mixed in a molar ratio of 1:1.1, and NaOH at a mass concentration of 0.5 wt% was added as a catalyst. The reaction was carried out at 100 °C for 5 hours. After completion of the reaction, the reaction solution was concentrated using a rotary evaporator. After drying, N,N-bis(2-hydroxyethyl)dodecanamide was obtained in 85% yield.
