N,N-Ethylenebisoctadecanamide - Introduction
N,N'-(ethane -1, 2-diyl) distearamide, also known as dioctyl acetate, is an organic compound. The following is a brief description of its nature, use, preparation and safety information.
Nature:
N,N'-(Ethane -1, 2-diyl) bisstearamide is a colorless to pale yellow waxy solid. It has good thermal stability and low volatility. It is insoluble in water at room temperature, but soluble in organic solvents, such as alcohols, ketones and aromatic hydrocarbons.
Use:
N,N'-(ethane -1, 2-diyl) bisstearamide is primarily used as a lubricant and plasticizer. It has a low melting point and a high coefficient of friction, so it is often used in the manufacture of plastic products, rubber products and greases. In addition, it can also be used as an additive for the preparation of high-performance coatings, inks and adhesives.
Preparation Method:
The preparation of N,N'-(ethane -1, 2-diyl) bisstearamide is generally obtained by reacting oxalic acid with octanol. The specific step is that oxalic acid and octanol are esterified in the presence of a catalyst to generate N,N'-(ethane -1, 2-diyl) distearamide. The reaction process needs to control the reaction temperature and reaction time to improve the yield and purity.
Safety Information:
N,N'-(ethane -1, 2-diyl) distearamide has low toxicity, but some safety matters should be paid attention. It may cause irritation to the skin, eyes and respiratory system, so it is necessary to wear appropriate protective measures during operation, such as gloves, goggles and masks. At the same time, it should also avoid long-term exposure to high temperature or fire sources to prevent it from burning. During storage and transportation, it should be kept away from strong acids, alkalis and oxidants, and stored in a cool and ventilated place. When a leak occurs, it should be removed quickly and prevented from entering the water source or soil to avoid environmental impact. If necessary, it is recommended to read and follow the safety guidelines for the relevant chemicals before use.
